BOOK I: THE THREE ROGUES


Chapter I: The Backsliding of Mr. Didbury Toke

THERE is nothing so deceptive as a half-truth. The half that is true has
a certain suggestive power that lends to the other half a plausibility
and a credibility that it does not possess in its own right. This
interesting psychological fact was realized, at least subconsciously, by
Mr. Didbury Toke. For Mr. Toke was a collector of antique and other works
of art, a connoisseur and a dealer. He really was. It was not a pose or a
pretence. He was a bona fide collector, and a connoisseur who had that
genuine love of fine and beautiful works that is the indispensable
condition of real connoisseurship. But Mr. Toke was also a fence. And
that was where the illusory element came in. Any person who, not being a
known collector and a recognized dealer, should have been seen, as he
frequently was, in the company of definitely shady characters, would
inevitably have attracted the attention of the guardians of the law. But
everyone knows that the really enthusiastic collector must needs seek his
quarry where it is most likely to be found; and there is no need to watch
him, for no crook or fence would be so foolish as to sell doubtful
merchandise to a collector who is going to expose it forthwith in his
show-cases, or a dealer who is going to offer it in the open market. So
Mr. Didbury Toke went about his lawful occasions unmolested and
unsuspected, and, under the cover of them, did a little unlawful business
if it happened to come his way.

It came his way pretty often in these latter days.

But this was a comparatively new development. For many years he had
carried on his activities in the most scrupulously correct manner. And so
he might have continued to the end, but for some exceptional
circumstance. We are all, indeed, the creatures of circumstance. But
circumstances are not entirely beyond human control. Their control is,
however, largely proportionate to our control of ourselves. And that was
where Mr. Toke had failed. At a critical moment he found himself unable
to resist a sudden temptation. But let us have done with generalities and
consider the circumstances in detail.

The descent to Avernus is proverbially easy; and, in practice, it is
usually somewhat gradual. But there are exceptions; and the case of Mr.
Didbury Toke furnishes an example. For his start upon that famous decline
was the result of an incident quite unforeseen and, to a certain extent,
beyond his control. At any rate, the determining cause--or perhaps we
should say the predisposing cause--was a convulsion of nature for which
he certainly could not be held responsible; being, in fact, no less than
a thunderstorm. Mr. Toke did not like thunderstorms. Few of us do;
especially when they come on us in the open country, in which the only
refuge visible is the illusory shelter offered by scattered hedgerow
elms.

At the moment Mr. Toke was pursuing his way along the rather unfrequented
road that led from the village in which his house was situated to the
neighbouring market town of Packington. As he walked at an easy pace on
the grass verge of the road, his thoughts were pleasantly occupied by
reflections on a little windfall that he had recently picked up at a
country auction; so much so that his immediate surroundings received but
the vaguest attention. Suddenly, he was aroused from his meditations by a
low rumble from the far distance behind him, and, turning sharply, became
aware of an obvious inkiness of the sky, and, low down, an arched edge of
blackness surmounting a pale area in which, even as he looked, jagged
streaks of light shot up from the dim horizon.

Mr. Toke looked about him uneasily. He had passed no habitation, so far
as he could remember, for the last mile; and Packington lay some two
miles farther on. But, clearly, it was useless to think of turning back.
His only chance of shelter, apart from the treacherous elms, was in some
possible inn or cottage that might lurk unseen by the roadside ahead.
Accordingly, he resumed his progress in that direction, mending his pace
appreciably as his ears were smitten by a sound as if a Brobdingnagian
tea-tray had been kicked by a Titanic foot.

Swiftly Mr. Toke padded along the solitary, inhospitable road while the
leaves of the elm trees shivered audibly and elemental bangings from
behind announced the approach of the storm. And then, just as the first
big drops began to fall with an audible plop on the earth, a slight turn
of the road revealed a cottage, hitherto hidden by a clump of trees. It
was but a humble labourer's dwelling, timber-built and roofed with
thatch, but to Mr. Toke's eagerly searching eyes it was more grateful
than a baronial mansion. As a resounding crash from behind mingled with
the hiss of a sudden deluge, he frantically unfastened the button of the
gate and darted up the path to the small porch that sheltered the door.
Nor did he come as a mere suppliant doubtful of his welcome; for, on the
jamb of the door hung a small board bearing the single word "TEAS." It
was a laconic announcement; but brevity is the soul of wit; and to Mr.
Toke it was as a charter of freedom conferring the right to enter
unquestioned.

The door was opened in response to his rather urgent thumps by an elderly
labourer, who looked first at Mr. Toke and then at the sky, as if he
suspected the former of some responsibility for the unfavourable state of
the weather. But he uttered no word; and, as the rain was playing freely
on Mr. Toke's back, that gentleman proceeded bluntly to state his wants.

"Can I have some tea?" asked Mr. Toke.

The man seemed surprised at the request. "Tea, you wants," said he. He
took another critical survey of the landscape, and then replied
cautiously: "I'll ask the' old woman."

As "the old woman" was plainly in view, sitting by the fire and obviously
attentive to the conversation, the precaution seemed hardly necessary. In
fact, she anticipated the question.

"Why, certainly, Tom; I can get the gentleman a cup of tea if he wants
one." She rose stiffly from her chair and cast an enquiring glance at the
kettle which reposed in unpromising silence on the hob.

"You have a notice by your door that you supply teas," Mr. Toke ventured
to remark.

"Yes," the master of the house admitted; "that there board was put up by
my darter. She's gone and got married, so we don't do much in that line
nowadays. Never did, in fact. Oo's coming out 'ere for tea?"

Mr. Toke agreed that the road was not actually congested, and, meanwhile,
under the guidance of his host, squeezed himself past an obstructive
table towards a Windsor arm-chair which he distinguished with some
difficulty in the pervading gloom. For, now that the door was closed, the
room was almost in darkness, the small window, obscured by dirt and
invading creepers, admitting only a fraction of the feeble light from the
inky sky.

"Seems as if we was going to have a bit of rain," the host remarked, by
way of making conversation. Mr. Toke agreed that there was a suggestion
of moisture in the air, and ventured to express the hope that it would do
the country good.

"Ay," said his host, "a bit of rain is allers useful at this time o'
year. In reason, mind yer. Yer don't want it a-comin' down like
brickbats, a-flattenin' down the crops. A nice, soft, steady rain is what
ye wants for the land. Keeps it miste, d'ye see."

Mr. Toke assimilated this lucid explanation as he watched the old woman
coaxing the unresponsive kettle with sticks of firewood. By degrees, his
eyes were becoming accustomed to the obscurity. Already, he had converted
the sound of harsh, metallic ticking into the visual impression of a drum
clock, perched on the mantelshelf, and now let his glance wander
questingly round the dim interior, it was not an idle glance. By no
means. Not, it is true, that he was ordinarily much concerned with the
simple domestic antique. But all is fish that comes to a collector's net;
and experience had taught him that if "Honesty lives in a poor house,
like your fair pearl in your foul oyster," so was it occasionally with
the treasures that the past has bequeathed to the present. So Mr. Toke
had made it a rule of life to "keep his weather eyelid lifting" even in
the most unlikely surroundings.

"Main lucky for you, it is," remarked his host, as a resounding crash
shook the door and made the window-frames rattle, "that you struck this
house in time. There ain't another this side of The Rose and Crown, and
that's a good mile and a half further on down the road. You'd a-caught it
proper if you'd a-been out in it now."

"Yes, indeed," said Mr. Toke. "Holy water in a dry house is better than
this rain-water out of doors."

His host did not, apparently, recognize the quotation, for he looked at
him suspiciously, and replied in a somewhat surly tone:

"There ain't no holy water in this house. We're Baptisses, we are."

"Ha," said Mr. Toke; "I was merely repeating an old saying. And there is
some truth in it, you know."

"So there may be," was the grudging reply. "I don't hold with none of
them there superstitions. Lord! Look at that!"

"That" was a blinding flash that flooded the room with violet light, and
was instantly followed by a shattering crash directly overhead, as if
some aerial three-decker had fired a broadside straight down the chimney.
The instantaneous flash, followed by what seemed to the dazzled eye a
period of total darkness, left Mr. Toke with a strangely vivid impression
of the cottage interior, in which all its details were clearly visible:
the seated figure of his host, the old woman, standing by the fire, the
tea-pot poised in her hand, the little dresser with its modest crockery
set out in an orderly array, and one or two pictures on the wall. But all
these things lay, as it were, on the margin of his field of vision, seen,
indeed, but only half-consciously perceived. For it happened that, at the
moment of the flash, Mr. Toke's eyes had been fixed upon a dim square
patch of paleness that was just barely discernible in the darkest corner
of the room, and he had been speculating on the nature of the object to
which it appertained. The flash solved that problem. The pale, square
patch was the dial of a long-case clock. Anyone could have seen that
much. But Mr. Toke saw a good deal more. It is true that the object was
seen only for an infinitesimal fraction of a second (plus a further
sixteenth of a second for what the physiologists call "the persistence of
visual impressions"), and that in that instant of time it had revealed
little more than a dark silhouette. But a silhouette may be highly
significant. It was to Mr. Toke. The square-headed hood, flanked by
twisted pillars, the slender body, the low plinth, taken together,
suggested a date before the time of good Queen Anne. There were, indeed,
two hands--pointing to an impossible hour and clearly indicating that
the clock was not a "going concern"--but there was nothing incongruous
in this, for two-handed clocks and even eight-day movements, were made
before the dawn of the eighteenth century.

But what really did worry Mr. Toke was the appearance of the dial. It was
obviously white. Now the seventeenth-century clock-maker had a soul above
a painted dial. If this dial was painted, as it appeared to be, there
were two possibilities; either the old dial had been barbarously covered
with paint, or, at some time, the clock had fallen into the hands of a
Philistine and had its original movement replaced by a new one.

It was a momentous question, and Mr. Toke debated it anxiously as he
stirred his tea and kept up a rambling conversation with his host. Of
course, it was none of his business--at least one would have said so.
But one would have been wrong. Mr. Toke intended to make it his business.
There are, indeed, some who maintain that to strike a keen bargain with
an ignorant man who happens to possess some valuable object is a base act
almost tantamount to robbery. This was not Mr. Toke's view. He held most
emphatically that the expert was fully entitled to the usufruct of his
knowledge. And there is something to be said for this point of view. A
man does not become a connoisseur without the expenditure of time,
effort, and money; and as to the person who, by chance inheritance,
happens to possess a Rembrandt or a Leonardo and elects to use it as a
tea-tray or to cover up a damp place on the wall, it is not easy to grow
sentimental over his rights. After all, the base collector rescues the
treasure from imminent destruction, and preserves it for the benefit of
mankind at large.

At any rate, Mr. Toke, recalling the fugitive vision of that elegant
silhouette, kept an acquisitive eye on the dim, pale square, which, like
the grin of the Cheshire cat, persisted when all else had vanished, and
cast about for some mode of strategic approach to the subject. Presently
his host, all unconsciously, gave him an opening.

"You takes your tea early," he remarked (it had just turned half-past
three).

Mr. Toke pulled out his watch and glanced at the drum clock on the
mantelshelf.

"Is your clock right?" he asked.

"Ay--leastways as near as I can tell. I sets him by the carrier's cart.
He go past every morning at nine o'clock, sharp."

"Ha," said Mr. Toke, "and does it keep good time--the clock, I mean?"

"Ay, he do that; wunnerful good time he keeps. And I only give three
shillings for him, brand noo."

"Really," said Mr. Toke. "It's surprising how cheap clocks are nowadays."

"Ay," agreed the host, "times has changed. It's what they calls progress.
Now, that old clock in the corner, he wasn't never bought for three
shillings; no, nor for three pund."

Mr. Toke stared into the dark corner indicated, as if he had not noticed
the clock before. But the corner was less dark now; for, with the last
crash, the storm seemed to have spent its wrath, and now a gleam of
sunshine stole in at the window and so brightened up the room that the
shape of the clock became distinctly visible.

"No," Mr. Toke concurred, "there were no three-shilling clocks in the
days when that was made. Have you had it long?"

"Had him from my old woman's grandfather. And he had him from the squire
what he was coachman to. So he wasn't made yesterday. He's like my old
woman and me: he's one of the has-beens."

"Does it keep good time?" Mr. Toke asked, regardless of the wildly
erroneous position of the hands.

His host chuckled. "Don't keep no time at all. Won't go. My darter's
husband has a tinker at him now and again--he's a plumber and gas-fitter
by trade--but it ain't no use. The' old clock's wore out. Takin' up room
to no purpose. Chap offered me five shillin' for him, and I'd a-took it.
But my old woman said no. So we kep' him."

"It wasn't a very liberal offer," Mr. Toke remarked.

"That's what I thought," said the old woman. "'Twasn't enough for a good
old clock, even if it won't go. I said so to Tom at the time."

"Well," growled Thomas, "who's a-going for to pay good money for a clock
what won't even tick?"

Mr. Toke decided that the time had come to open negotiations.

"There are such people," said he. "I have a friend who has quite a fancy
for old clocks. He would probably be willing to give you a couple of
pounds for it."

"Then," said Thomas, "I be glad if you'd send him along this way. What
d'you say, Susan?"

"Two pounds 'ud be very useful," replied the old woman. "But I doubt if
he'd give it when he see the clock. It be terrible old."

Mr. Toke rose and strolled across to the corner. The light was now quite
good, and at close quarters it was possible to make out the details. And
at some of those details Mr. Toke's gorge rose, and he half regretted the
liberality of his offer. The venerable time-piece had received the most
shocking treatment from some Vandal. The case was encrusted with varnish,
apparently applied with a tar brush, and the brass dial had received a
thick coat of white paint. Yet, through the treacly depths of the varnish
and the layer of paint, other details were faintly discernible which he
noted with deep satisfaction.

The clock had been an aristocrat in its day. The dark wood of the case
was richly ornamented with marquetry, and a framed panel seemed to
enclose some initials and a date, though Mr. Toke could not actually
decipher them. But their presence hinted at a possibly traceable
history, which would greatly enhance the value of the piece. A
glance at the dial showed it to be undoubtedly the original one. The
corner ornaments--simple cherubs' heads--were quite characteristic
of the period, as were the hour and minute figures, where they were
distinguishable, and the hands, though their form was obscured by a
thick coat of black enamel paint, showed the simple elegance that marks
the work of the earlier makers. Mr. Toke, seeking in vain to decipher
the maker's name, was reassured. Perhaps, after all, the plumber's
contribution did not go beyond the paint and the varnish.

"Do you happen to remember the name of the squire who originally owned
the clock?" Mr. Toke enquired.

"His name was Hawkwood," the old woman replied. "Sir John Hawkwood."

Mr. Toke made a mental note of the name and announced: "I am inclined to
think that my friend would be willing to give a couple of pounds for this
clock, if you are prepared to sell it."

Thomas was undoubtedly prepared to sell, and said so with some emphasis;
and the old lady opined that two pounds would be more useful than the
clock.

"Very well," said Mr. Toke, "then we will consider the matter settled.
How am I to get the clock to my house?"

"Where is your house?" the practical-minded Thomas demanded.

"I live at Hartsden Manor; just outside the village."

"I knows him," said Thomas. "A tumbledown old house just alongside the
old church what is shut up. 'Tain't fur from here. A couple of mile. I
could run th' old clock down in my barrer."

"When?" asked Mr. Toke.

"Now, if yer like. I suppose yer pays on delivery?"

"Certainly. When I receive the clock, you'll receive the money."

With this stimulus, Thomas awoke to strenuous activity. The clock was
hauled out of its corner, and, while Mr. Toke detached the pendulum and
secured the weights in a packing of spare garments, old Susan went in
search of a blanket, and Thomas retired to fetch the "barrer." In a few
minutes all was ready. The clock, decently swathed in the blanket, and
faintly suggesting an impending inquest, was tied firmly on the barrow
and Thomas signified that the procession was ready to start.

The journey to Hartsden was, for the most part, uneventful. One or two
wayfarers on the road greeted the barrow and its burden with surprised
grins, and, at the entrance to the village, a group of schoolboys, just
released from bondage, formed up into an orderly procession and followed
the barrow, two by two, with bare and bowed beads and unseemly giggles; a
proceeding that attracted unnecessary attention, and added appreciably to
the gaiety of the neighbourhood for the time being.

"Passel o' grinnin' fules," said Thomas, casting a resentful and
contemptuous glance at the little party of smiling bystanders as he drew
up at the gate of the house while Mr. Toke unfastened it to admit him to
the short drive. As the gate swung open, he stooped to grasp the handles
of the barrow at the moment when one of the juvenile mourners advanced,
with his hand kerchief held to his eyes, to drop a dandelion on the
shrouded clock.

The business was soon concluded to mutual satisfaction. The clock was
conveyed to a disused room at the back of the house and deposited on a
rough table. Then Mr. Toke wrote out a receipt in such terms as amounted
to a formal conveyance of the property, and, when the vendor had
subscribed his sign manual, two sovereigns were laid on the table.

"Thank ye, sir," said Thomas, transferring them to his pocket. "I hopes
the clock will suit your friend. I shouldn't like to think of it being
left on your hands."

"He'll have to take it now that I have paid for it," replied Mr. Toke.
"But you needn't worry. He'll be quite satisfied."

In point of fact, the "friend" was more than satisfied. A rapid
inspection showed that the case was in excellent condition under the
crust of varnish; and through the latter, it was now possible to see that
the dark walnut was adorned with marquetry of a richness unusual in such
early work. For, in the strong light, the date was clearly legible as
well as the initials, grouped in a triangle around a heart--J. H. M.
1692, the H being uppermost, and, as Mr. Toke reasonably surmised,
representing the name, Hawkwood. The dial and hands, too, were of
appropriate style and of the same excellent workmanship; and on the
former could now be deciphered, through the paint: "Robert Cooke,
Londini, fecit."

From this general, preliminary inspection Mr. Toke proceeded to the
consideration of details. He had already noticed that the case was closed
at the bottom. Now, on opening the door, he observed a partition closing
the interior space at an appreciably higher level. This was rather
remarkable, for the position of this upper partition was such as possibly
to interfere with the proper fall of the weights. But what was still more
remarkable was the way in which it was secured. There were four screws;
but, though the wood of the partition appeared to be old, the screws
certainly did not. Their bright, clean heads seemed to shout,
"Nettlefold."

Mr. Toke was quite interested. Between those two partitions there must be
a space. That space might be an ancient hiding-place. But the screws
hardly supported that view. At any rate, the question could soon be set
at rest. And the first turn of the screwdriver settled it. The readiness
with which the screw turned suggested a touch of tallow; and a greasy
stain on the wood around the hole was clear confirmation. The other three
screws followed with the same ease, and then, by inserting a bradawl into
one of the holes, it was possible to prise up the loose partition.

Now, whether this had or had not been an ancient hiding-place, it was
quite clear that the contents were modern; consisting of a parcel wrapped
in undeniable newspaper. Mr. Toke lifted it out, and, having cut the
string, carefully opened it. And then he got the surprise of his life.
There were several layers of paper, the innermost being of clean tissue
paper; and, when the last of these was turned back, there was revealed to
Mr. Toke's astonished gaze a magnificent diamond necklace and a still
more magnificent pendant.

For some moments he stood staring at the gorgeous bauble, lost in
amazement. Then a slow grin stole over his face. Now he understood how it
was that the "tinkerings" of the plumber and gas-fitter had failed to
make the clock go. "My darter's husband" had had other fish to fry. But
that estimable artisan seemed to have taken unnecessary risks, for the
door had a lock. Apparently it was not in working order, and the key was
missing (perhaps in the plumber's possession). Common prudence would have
suggested a repair to the lock. But, possibly, it had been left for fear
of attracting attention. Thomas was not, it had seemed, gifted with a
peculiarly enquiring mind. Perhaps the plumber had adopted the more
prudent course.

But the obvious question arose, What was to be done? Mr. Toke believed
that he recognized the necklace. He thought that he recalled a daring
daylight robbery at a great London house when the thief had entered a
bedroom by way of a stack-pipe while the family were at dinner and got
away unseen with a diamond necklace--presumably this very one--said to
be worth £20,000. There would therefore be no difficulty in discovering
the owner. Indeed, there was no need for him to do anything of the kind.
All that was necessary was to report the discovery to the police. And
this was what occurred to Mr. Toke as the obvious thing to do.

But was it so very obvious, after all? Mr. Toke looked at the necklace,
and somehow the obviousness of that course of action seemed to grow less.
In the course of his rather varied life, Mr. Toke had been connected for
a year or two with the diamond and gem trade. That tended strongly to
influence his point of view. It was not that he was a great judge of
gems. He was not; though, of course, he could price a stone
approximately. But the vital fact, in regard to the present transaction,
was that he knew the ropes. The man who had stolen this jewel had been
reduced to the necessity of hiding it until such time as he should find a
"fence" who would take the incriminating treasure off his hand and ask no
questions. And what would that fence pay him for it? No more than a
paltry fraction of its real value. Now he, Mr. Toke, could dispose of it
at something like its market price.

He looked at it with a calculating eye. It was a fine necklace. Probably
report had not greatly over estimated its value. Every stone in it was a
valuable stone. But there was no one of those fine brilliants that was of
spectacular value. Not one of them was of a size that would involve
questions or possibly lead to identification. He could safely deal with
any of them in the ordinary market.

And, after all, why not? He had not stolen the necklace. So far as he was
concerned, it was a case of treasure trove, pure and simple. So he told
himself, casuistically trying to smother his not very lively scruples. Of
course, he knew quite well that he was contemplating a theft. But,
although, up to this time, he had been a least conventionally honest, he
was, if not actually avaricious, highly acquisitive by nature, as is apt
to be the case with collectors. He had the passion to possess; and, even
if he had been unable to dispose of these diamonds, he would still have
been reluctant to give them up.

The conflict in his mind was not a long one. There were the diamonds--ten
thousand pounds' worth of them, at a moderate estimate--staring him
in the face and inviting him to accept the gifts of Fortune. There was
absolutely no danger. The transaction was as simple and safe as an
ordinary commercial deal. Suppose the plumber should denounce him to the
police. It was wildly improbable; but suppose he did? Well, who was going
to prove that the diamonds were ever there? The plumber's unsupported
testimony would go for nothing; and apart from him, there was,
presumably, no one who had any knowledge of their whereabouts--unless
it was "my darter." But neither of these was in a position to swear that
the diamonds were in the clock-case when it was removed from its late
owner's custody. Mr. Toke's position was impregnable. He simply knew
nothing about the matter.

But he was not going to leave it at that. No sooner had he taken the
fateful resolution to treat this gorgeous derelict as treasure trove than
the inevitable psychological effect began to manifest itself. The
contemplation of a criminal act immediately began to generate the
criminal mentality. Safe as the enterprise was, he was going to make it
safer. The tracks, already confused, must be further confounded. His
intention had been to clean the case himself. He was a fairly expert
french polisher. Not that he had contemplated french polishing this old
case. On the contrary, his intention had been to un-french-polish it. But
now he realized the inexpediency of meddling with it at all. It should
go, just as it was, for treatment to some third party. Thus would the
issues be further confused.

Having made his decision, he acted promptly. The very next day he
conveyed the clock to a roomy closed car that he had lately adopted, and
bore it up to town. There he deposited the movement at the premises of a
reliable "chamber worker" in Clerkenwell for a careful overhaul, and then
carried the case to Curtain Road and handed it to a skilful cabinet-maker
with the instruction that it was to be cleaned and wax-polished, but left
structurally intact, with the exception of any trifling repairs that
might be unavoidable. The lock was to be repaired and fitted with a key
of the correct pattern according to the date on the panel.

When he had done this, Mr. Toke felt that he had made his position
unassailable. He allowed himself to hope that he would be left in
undisputed possession of his treasure trove. But his hopes were tempered
by a suspicion that he had not heard the last of the worthy Thomas's
too-ingenious son-in-law. And subsequent events justified his suspicions.

Chapter II: Enter Mr. Hughes

IT was a little over a week after his acquisition of the clock that Mr.
Toke's forebodings began to be realized. On that day, about eleven in the
forenoon, his house keeper, Mrs. Gibbins, came to him as he sat in his
study writing letters, and announced with something of an air of mystery
that a man wished to see him.

"A man?" Mr. Toke repeated. "Do you mean a gentleman?"

Mrs. Gibbins made it extremely clear that she did not.

"Did he say what his business was?"

"No, sir. I asked him, but he said he wanted to see you on private
business. He wouldn't say what it was. He is waiting in the hall. I told
Margaret to keep an eye on him." (Margaret was Mrs. Gibbins's niece and
functioned as housemaid.)

"Well," said Mr. Toke, "I suppose you had better bring him in here. But I
can't imagine who he can be"; which was not perfectly candid on Mr.
Toke's part. He had a strong suspicion that the visitor would turn out to
be an exponent of the plumbing and gas-fitting arts. And even so it
befell. When Mrs. Gibbins returned, she was accompanied by a somewhat
seedy stranger of truculent aspect, whose appearance suggested a Labour
agitator or a working man of strongly political leanings.

"Well," said Mr. Toke, when the housekeeper had retired, "what is it that
you want to see me about?"

His visitor crept towards him with an air of mystery and secrecy, and
replied impressively:

"It's about a clock what you bought off of my father-in-law, Mr. Hobson."

"Yes," said Mr. Toke, "I remember. An old clock, a good deal out of
repair. Yes. What about it?"

"Well, you see, Mr. Hobson hadn't got no right for to sell you that
clock. 'Twasn't his for to sell. That clock belongs to my wife. It was
give to her as a wedding present."

Mr. Toke reflected rapidly. It would be perfectly practicable to restore
the clock, since its contents were now securely concealed in an
undiscoverable hiding-place. The clock, itself, valuable as it was, had
become, by comparisons negligible. Nevertheless, Mr. Toke's strongly
acquisitive temperament made him reluctant to disgorge. Besides, to what
purpose should he restore the clock? Its return, empty, would not dispose
of the business. It was not the clock but the necklace that this worthy
craftsman was seeking. And then there was the practical certainty that
his statement was a barefaced untruth. No; there was nothing to be gained
by an attempt to compromise.

"This is very unfortunate," said Mr. Toke; "but I am afraid you will have
to settle the matter with Mr. Hobson. He has the money. I have no doubt
that, if you put it to him, he will hand it over to you."

"But my wife don't want to sell the clock, nor more don't I."

"Ha," said Mr. Toke, "that is a pity; because, you see, the clock has
been sold. I bought it in a perfectly regular manner, and I have Mr.
Hobson's receipt for the price of it."

"But don't I keep telling yer that old Hobson hadn't no right for to sell
it?"

Mr. Toke admitted that the matter had been mentioned. "But," he
continued, "that is really not my concern. You must settle the affair
with your father-in-law."

"Ho, must I? Fat lot of good it 'ud be talking to him. No, Mister, I'm
going to settle with you, I am. You've got my clock, and you're going to
hand it over. I've got the barrer outside."

Mr. Toke complimented him on his providence, but declined to consider the
demand.

"Look here," the stranger exclaimed in a threatening tone, "if you don't
want any trouble, you just hand that clock over. I'm going to have it,
you know. I'm going to make you hand it over. See? You think I; can't,
but I tell you I can."

"I am sure you can," Mr. Toke agreed. "That is just my point. If the
clock is yours, you can compel me to return it. All you have to do is to
go to your solicitor, give him proof of your title to the property and
instruct him to recover it in the ordinary way. He will make no trouble
about it."

"Gawd!" exclaimed the other. "I don't want all that trouble and fuss. And
I don't want no solicitors. I shall just inform the police."

"Yes," said Mr. Toke, "you could do that. If your father-in-law did
actually sell a clock that was not his property, he undoubtedly was
guilty of a criminal act. You might prosecute him. So might I, for
obtaining money from me by false pretences. But you would have to prove
that the clock was yours, in any case. It would be less trouble to
instruct a solicitor, and you would avoid the scandal."

Mr. Toke's calm, detached attitude seemed rather to nonplus his visitor,
for the latter stood for some time gazing at him, breathing hard but
uttering no word. At length he resumed, in a milder, even pacific tone:

"I don't want to make no trouble for old Hobson, seeing as he is my
wife's father. And I don't want no truck with solicitors. I'll tell you
what I'll do. You hand me back that clock, and I'll give you the two quid
what you paid for it. I can't say no fairer than that."

But Mr. Toke shook his head regretfully. "I am sorry, Mr.--I didn't
quite catch your name--"

"My name is Dobey, Charles Dobey, if you want to know."

"Thank you. I was saying that I am extremely sorry that I can't accept
your offer. But, to begin with, the clock is not here; and as I have
already spent a substantial sum of money on it, I should not be prepared
to sell it at the price that I gave for it."

"What do you mean about spending money on it?" Mr. Dobey asked with
evident uneasiness.

"Well, you see," said Mr. Toke, "in the first place, I had to send the
case to a cabinet-maker's--"

"What!" gasped Dobey. Then, controlling himself, he demanded, huskily:
"What was the cabinet maker going to do to it? There wasn't nothing the
matter with the case."

"Nothing structural," Mr. Toke agreed. "But it wanted a clean up. I told
him to clean off all the old varnish and put on a slight wax polish. That
was all. And I have had the movement put in order. So you see, the clock
is now worth a good deal more than I gave for it."

"And where is it now?" Mr. Dobey asked, gloomily.

"I have sent it to Messrs. Moore and Burgess, the eminent auctioneers,
and I understand that it will be put up for sale next Thursday--a week
from to-day."

Mr. Dobey reflected on this statement with an expression compounded of
dejection and bewilderment. And, meanwhile, Mr. Toke looked him over,
critically. He was not much to look at. He presented none of those
interesting "stigmata" that distinguish the criminal countenance in the
plates of Lombroso's treatises. He was just a common "low-grade" man of
the type that may be seen by the dozen, taking the air in the exercise
yard of any local prison; with darkish red hair and--not unusually--a
nose to match; hands suggestive of deficient washing rather than
excessive labour and a noticeably shifty and furtive cast of countenance.

At length be pulled himself together for a final effort.

"This is all very well, you know, Mister, but I can't allow you to put up
my clock to auction just as if it was your own. You'll have to get it
back; and I'll make you an allowance for what you've spent on it."

"I'm afraid I can't agree to that." said Mr. Toke. "You seem to be
forgetting that, at present, I am the legal owner of that clock. The
receipt that I hold establishes my ownership; and if you claim that the
clock is yours, it is for you to produce evidence of ownership. You
haven't done that, you know; and, if you haven't any papers to prove that
it was given to your wife, I don't think you would be able to do it."

"I could swear a affidavit," said Mr. Dobey.

"M'yes," agreed Mr. Toke. "But you have to be a bit careful about
affidavits. There is such a thing as perjury, you know. I shouldn't
recommend an affidavit."

Mr. Dobey received this advice with a bewildered stare. He could make
nothing of it. Mr. Toke's bland, impersonal attitude left him, for the
moment, speechless. At length, he asked, lamely:

"Well, what am I to do? I ought to be able to get my own clock
back--leastways, my wife's clock."

"So you are," said Mr. Toke. "There's nothing to prevent you from going
to the auction and bidding."

For some moments Mr. Dobey was too much over come to be capable of any
reply. At last, he exclaimed, hoarsely:

"Well, I am blowed, I reely am. You've got the blinkin' sauce to tell me
to go to the blinkin' auction and buy in my own clock. And you to take
the money. I never heard the likes of it!"

"I merely threw out the suggestion," said Mr. Toke. "I thought you were
anxious to get the clock. You could always sell it and get your money
back, you know."

Futile as the suggestion seemed, it was craftily conceived; and Mr. Toke,
furtively watching his visitor, saw that it had taken effect. The
aggressive expression faded out of Mr. Dobey's countenance and gave place
to one indicative of reflection.

"Where do these auction blokes hang out?" he asked after a longish pause.

Mr. Toke took out from his letter case a card on which was inscribed,
"MR. DIDBURY TOKE, 151 QUEEN SQUARE, BLOOMSBURY. TUESDAY AND FRIDAY, 11
to 5, OR BY APPOINTMENT." On the back of this he wrote the address of the
auctioneers, and handed it to Mr. Dobey; who, having read what was
written, turned the card over and studied the printed inscription.

"I'll have to think over this," he remarked gloomily; and then, as if a
new idea had struck him, he demanded:

"What is the name of the cabinet-maker what did the clock up?"

"His name," said Mr. Toke, writing on a slip of paper as he spoke, "is
Levy, Maurice Levy, and his place is in Curtain Road."

"Sounds like a sheeny," Dobey remarked, disparagingly.

"He is, as you have guessed, of the Jewish faith," Mr. Toke admitted. "A
most excellent workman and a thoroughly honest man."

"Ho," said Mr. Dobey, in a tone of obvious scepticism. But he seemed to
get some comfort from the description, nevertheless. He gazed
reflectively at the slip of paper for a while, and then, slowly and
reluctantly, rose.

"Well," he remarked in an aggrieved tone, "this ain't what I expected,
but I suppose there's no use staying here chin-waggin' to no purpose."

He moved dejectedly towards the door, and Mr. Toke piloted him to the
hall and launched him with a suave "Good morning" from the front door,
watching him with a faint smile as he slouched down the short drive. He
was not dissatisfied with the result of the interview. His subtle hint
had evidently taken effect. And, though there would certainly be trouble
if Dobey really bought the clock, it would be better so than that some
other purchaser should have his house burgled, with the possibility of a
capture and awkward explanations.

On the following Wednesday, the day before the sale, Mr. Toke arrived
betimes at the rooms of Messrs. Moore and Burgess to watch the company of
dealers and connoisseurs who had gathered to view the goods that were to
be sold on the following day. There were two large rooms, connected by a
wide doorway; and, immediately opposite the doorway, the clock was
standing, ticking solemnly in proof of its perfectly restored health. Mr.
Toke halted before it and surveyed it with not unpardonable pride. By the
joint efforts of Mr. Levy and the Clerkenwell artist, the shabby outcast
that had cumbered the floor of Thomas Hobson's cottage had been restored
to its rightful status as an aristocrat among clocks. The fine, dark
walnut case with its rich marquetry had emerged from the crust of varnish
as a butterfly comes forth from its pupa-shell; the brass dial with its
cherub-heads and its silver hour-circle had been cleansed of the paint,
and yet not cleansed too much, and the hands once more showed the fine,
simple workmanship of their period.

Mr. Toke stood and let his eyes travel over its revived beauties with the
genuine pleasure of the connoisseur, congratulating himself on having
been the means of rescuing it from its unworthy surroundings and the risk
of destruction. But, even as he gloated, he kept a watchful eye on the
entrance through which new-corners were constantly pouring in; and it
was, perhaps, just as well that he did; for, even as he held the narrow
door of the clock open and peered in to see that the partition had not
been tampered with, the countenance of Mr. Dobey came into view among the
little crowd of new arrivals.

Now there was really no reason why Mr. Toke should have made any secret
of his presence in the rooms. As a collector, it was quite natural that
he should be there. But recent transactions had engendered in him a new
furtiveness and secrecy. He didn't want Dobey to see him, and he did want
to keep an eye on Dobey. Accordingly, having shut the clock-case, he made
his way, as well as the crowded state of the rooms would let him, through
the doorway into the other room, and looked about for some means of
concealment. A large French armoire seemed to offer the best cover, for,
from the shadow behind it, he could get a good view of the adjoining room
in a large mirror.

Here, then, he established himself, and soon the bereaved artisan came
into view. He was quite respectably dressed, and would have been
unnoticeable but for the self-consciousness which caused him to move
stealthily and suspiciously among the crowd. Very soon he spied the clock
and crept up to it with ill-assumed unconcern. Mr. Toke watched him with
grim amusement. Evidently, the changed appearance of the clock puzzled
him considerably. The distinctive characteristics, now so striking, had
been hidden by the varnish, and were unfamiliar to him, He stared at the
clock, and then gazed about in search of another. But this was the only
clock in the room. Finally, after a furtive glance to right and left, he
ventured to open the door of the case and peer in. Then, evidently, some
chord of memory was struck. No doubt the four Nettlefold screws were old
friends. At any rate, he closed the door with an air of decision, and
once more began to look about him furtively and uneasily, while Mr. Toke
watched expectantly to see what his next move would be.

For some time Dobey crept to and fro rather aimlessly, gazing at the
exhibits, but keeping in the neighbourhood of the clock, and Mr. Toke had
the feeling that he was waiting for someone. And so it turned out,
presently. The meeting was singularly unostentatious but Mr. Toke,
watching narrowly, noted the mutual recognition. The new-corner was a
well-dressed man, obviously of a superior class to Mr. Dobey, who walked
in confidently, and, having looked round, glanced at the catalogue that
he held and then walked straight up to the clock. He stood before it and
surveyed it critically, point by point; tried the lock, opened the door
of the case, gazed into the interior and reclosed it. And it was at this
moment that the meeting took place. There was no sign of recognition;
but, as the stranger stood inspecting the clock, Dobey sidled up, and for
a moment stood by his side. Nothing appeared to be said, but the stranger
made an entry in his catalogue. Then Dobey moved away, and, after a few
vague glances at some of the exhibits, faded away towards the entry and
vanished into the outer world.

With the disappearance of Mr. Dobey, concealment became no longer
necessary. Mr. Toke emerged boldly, and made his way into the other room
with the purpose of getting a closer look at Mr. Dobey's friend. The
circumstances were favourable for getting, at least, an unobserved back
view; and the observant Mr. Toke, beginning with a minute inspection from
the rear, arrived at the decision that the unknown wore a wig. It was an
exceedingly good wig; so good and well-fitting as to suggest a bald or
shaved head underneath. Having made this interesting observation, Mr.
Toke contrived to obtain a view of the stranger's face. It impressed him
as a rather curious face; but he presently realized that the peculiarity
of expression was due to the absence of eyebrows. Either they were
naturally deficient or they had been shaved off. The presence of the wig
suggested the former, but the meeting with Mr. Dobey made the latter
possibility quite conceivable. At any rate, the dark-brown wig, with eyes
to match, and the curiously blank forehead, rendered the stranger easy to
recognize; which was satisfactory, as Mr. Toke intended to keep an eye on
him, if, as seemed likely, he should turn up at the sale on the following
day.

And turn up he did. Mr. Toke, keeping a bright look-out, saw him come in,
catalogue in hand, and select a seat well in view of the auctioneer. Mr.
Toke saw him fairly seated and then found a place for himself, where he
could command an uninterrupted view of the stranger without making
himself conspicuous. As he was not going to bid, he had no need to be in
a position to catch the auctioneer's eye.

His vigil was not unduly prolonged, for the clock came early in the list.
As the number approached, he watched the wigged stranger; but his queer
blank face showed no sign of uneasiness. He watched the proceedings
stolidly, and did not even glance at his catalogue. Evidently, he was not
a jumpy man.

At length the fateful number was reached. The auctioneer cleared his
throat and announced, not without gusto:

"Long-case clock by Robert Cooke of London, dated 1692, in a case of fine
walnut wood, enriched with elaborate marquetry. A most exceptional lot,
this, gentlemen. It is really a museum piece. I have never seen a clock
of this early period in such perfect condition. It is virtually
untouched. With the exception of a modern partition in the bottom of the
case, there are no restorations or repairs. It is in the very condition
in which the maker turned it out. And I understand that an authentic
history accompanies it. The initials on the case are those of Sir John
Hawkwood and the Lady Margaret, his wife. Now, gentlemen, what shall we
say for this unique clock?"

Almost before he had finished speaking, a voice answered:

"Fifty pounds."

Mr. Toke grinned. This was, in effect, an ultimatum. The speaker meant to
have the clock, and made no secret of his intention. But he was not the
only pebble on the beach, as the vulgar saying has it. His challenge was
immediately taken up by another enthusiast.

"Fifty-five."

"Sixty."

"Sixty-five."

The bids followed one another with hardly a moment's interval, and the
price hopped up by fives until it reached a hundred and ninety. Then
there was a slight slackening; but still the bidding went on, at at a
reduced pace. And all the time the gentleman in the wig sat gazing
stolidly before him and uttering not a word. Mr. Toke began to be uneasy.
Was he not going to bid, after all? Had he merely come to get the name of
the purchaser with a view to a subsequent burglary? That was an
unpleasant position. Not that it mattered very much; but, still, Mr. Toke
didn't want a burglary. No one could say what disagreeable results might
follow. But at this point his anxieties were dissipated by a sudden
activity on the part of the wigged gentleman. The price had reached two
hundred and five, and, after the last bid, a somewhat lengthy pause
occurred. The auctioneer repeated the bid, solemnly, and his hand stole
towards his hammer. But at this moment, the wigged stranger looked at the
auctioneer and nodded.

"Two hundred and ten," the latter chanted, and repeated the refrain three
times with increasing emphasis. But now there was no answer. The
appearance of a new competitor at the eleventh hour was too much for the
others. After a long and anxious pause, the hammer came down with a sharp
rap and Mr. Toke drew a deep breath.

The name of the wigged gentleman, it transpired, was Hughes. As soon as
he had communicated this fact, he rose and walked over to the clock and
stood for a while surveying it with apparent satisfaction. Then he turned
the key in the lock, put it in his pocket and sauntered out of the room;
and, as the purchase of the clock left Mr. Toke with no further interest
in the proceedings, he also presently rose and left the premises. And, as
he wended his way to his office, he speculated, not without a shade of
anxiety, on the probabilities of the immediate future. Messrs Hughes and
Dobey were going to suffer a somewhat severe disappointment. It was not
likely that they would suffer in silence. He had a strong presentiment
that he had not heard the last of that necklace or of its quondam owners.
As to Dobey, he was a negligible ass. But Mr. Hughes was in a rather
different class. His conduct at the auction showed considerable judgment
and self-restraint. He was clearly a gentleman who knew his own mind; a
man of courage and resolution.

Mr. Toke was rather sorry that Mr. Hughes had come into the affair.

Chapter III: An Unholy Alliance

LOVERS of paradox assure us that it is the unexpected that happens.
Perhaps they are right. But the unexpected holds no monopoly. Sometimes
the expected happens. It did, for instance, on a certain Friday
afternoon--the very day, in fact, after the auction. On that day,
in accordance with the announcement on his cards, Mr. Toke was in
attendance at his professional premises. At the moment he was seated at
the writing-table in the inner room--it was hardly an office--writing
one or two letters. He was quite alone, for he had no clerk or
secretary. He had no use for one, since his business was entirely
personal and his transactions few, though the amounts involved were
usually substantial. So there he sat, writing his letters, but by no
means engrossed with the matter thereof.

To tell the literal truth, Mr. Toke was just a shade nervous. The auction
had not gone quite according to plan. He had reckoned on Mr. Dobey,
whereas he now had to deal with Mr. Hughes; which was a slightly
different proposition. Accordingly, he sat, making shift to write, but
with an attentive ear on the outer door.

It was within a few minutes of five o'clock, and he was preparing for a
scrupulously punctual departure, when the expected happened. The outer
door opened, and, through the slight opening of the door communicating
with the outer room, he saw a man enter. He rose, and, stepping out into
the other room found himself confronting Mr. Hughes. The visitor looked
at him critically and affirmed:

"I wish to see Mr. Didbury Toke."

"Fortunate man!" said Mr. Toke. "Your wish is realized even as you utter
it. In what way can I be of service to you?"

"I should like to have a few words with you in private," was the reply.

"Again," said Mr. Toke, with genial facetiousness, by way of keeping up
his spirits, "you are favoured. For here we are, solus cum solo, with
none to supervise, as the poet expresses it. You can say anything you
like and no one will be the wiser."

He led the way into the inner room, and, shutting the communicating door,
indicated a chair adjoining the writing-table, resumed his seat at the
table, and looked expectantly at his visitor.

"I have come to see you on behalf of Mr. Charles Dobey," said the latter.
"My own name is Hughes."

"I hope Mr. Dobey is not unwell," said Mr. Toke.

"He is not," was the reply; "but he wished me to act on his behalf, as
being more experienced in business affairs. The matter is this: a short
time ago you purchased from a certain Thomas Hobson an antique clock.
Dobey states that the clock was actually his property, but I am not going
into that. The point is, that there was certain property, which certainly
was Dobey's, concealed in that dock. He had been in the habit of using it
as a safe."

"What an extraordinarily stupid thing to do!" exclaimed Mr. Toke.

"I agree," said Mr. Hughes. "But he did. He stowed this property in a
cavity between two partitions, the upper of which was secured with
screws."

"Was this property of any considerable value?" Mr. Toke asked.

"I understand that it was."

"Dear me!" exclaimed Mr. Toke, "I wish I had known. May I ask what was
its nature?"

"I understand that it consisted of jewellery," replied Mr. Hughes. "But
the point is, that it has disappeared. Acting on Dobey's instructions, I
bought the clock, and Dobey removed the partition in my presence. The
cavity underneath was empty."

"Dear me," said Mr. Toke. "Was it, indeed? Now, I wonder how it can have
disappeared."

"Dobey assumes that you removed it, and it seems a reasonable
supposition. I have come to ask you what you propose to do about it."

Mr. Toke leaned back in his chair, and, placing his finger-tips together,
looked steadily at Mr. Hughes. He had, indeed, been looking at him
throughout the interview, and, as the light from the window fell full on
the queer, rather sinister face, he had been able to study it
advantageously. I use the word "study" advisedly; for at the first glance
he had been aware of a faint stirring of memory. Mr. Toke had an
exceedingly good memory for faces; and, although this face was strange to
him, yet, as he looked, it seemed to set some chord of memory vibrating.

"May I ask what leads you to suppose that I removed this property?" he
asked, without any sign of resentment.

"It is obvious enough," Hughes replied. "The property was there when the
clock came into your possession, and it isn't there now."

"But," protested Toke, "you seem to be over looking the number of hands
through which the clock has passed. There is the cabinet-maker, the
clock-maker who fitted the movement to the case, and various unknown
persons who had access to it at the auction rooms."

"And there is yourself, the only one of the lot who happens to have the
means of disposing of valuable jewellery."

"That is quite true," Mr. Toke agreed. "If Dobey had offered me the
jewellery, I could certainly have disposed of it to advantage.
Unfortunately, he did not. And you must see that my professional standing
has no bearing on the question as to who found the jewellery, assuming it
to have been really there. The fact is that I, of course, saw the
partition, and I saw that it had no business to be there. But I make it a
rule, when I buy a piece with the intention of selling it, to leave it
exactly as I find it. And I instructed the cabinet-maker to make no
structural changes in the case; otherwise, he would, no doubt, have
removed the partition, as it might be thought to stand in the way of the
weights. Still, it might be worth while to ask him if he did remove it."

"I have," said Mr. Hughes, "and he states very positively that he did
not. And I believe him."

"So do I," said Mr. Toke. "He is a most respectable man, and would, I am
sure, have reported to me if he had made any discovery. And so, I think,
would the clock-maker. If the property was really there, it must have
been abstracted by someone after it was delivered at the auction rooms."

Mr. Hughes received this statement in gloomy silence, but with a lowering
of the brows--or, at least, of the region where the brows should have
been--that plainly expressed his unbelief. But he did not leave it at
mere facial expression. After a somewhat lengthy pause, he said, in low,
emphatic tones:

"Look here, Mr. Toke, all this evasion is no good. You have got those
jewels. It is of no use your telling me that you haven't. I am perfectly
sure that you have."

"Very well," Mr. Toke replied calmly, "then there is no more to be said.
You have your legal remedy, you know."

"You know that we have nothing of the sort," replied Hughes. "I realize
that you can stick to them if you like. The question is, do you intend to
hold on to them, or are you willing to make some sort of arrangement with
Dobey?"

Mr. Toke reflected. Once before, when he had discovered the jewels, he
had stood at the cross-roads; and he had taken the wrong turning. Now he
stood at the cross-roads again. Should he share the loot with these two
rascals, or should he accept the gifts of Fortune and snap his fingers at
them?

It was a momentous question; more momentous than he knew. If he could
have looked into the future and seen the consequences that hung on his
decision, that decision might have been very different. But Mr. Toke was
like the rest of us. He could be wise enough after the event. But the
future was a matter of guess work. And it is always possible to guess
wrong. Probably Mr. Toke guessed wrong on this occasion. At any rate, he
made the fateful decision; and the future was to show that it was the
wrong one.

"I cannot be committed to any opinions that you may have formed," said
he. "As to these jewels, I feel no conviction that they were ever there.
Mr. Dobey is a plumber and gas-fitter. Now, what has a gas-fitter to do
with valuable jewels?"

"We need not go into that," Mr. Hughes said, brusquely.

"Very true. We need not," Mr. Toke agreed. "There is certainly a
particular kind of gas-fitter who comes into the possession of valuable
jewels. But he is not an honest kind of gas-fitter, whose word could be
accepted without proof. I am very doubtful about those jewels."

"Then I take it that you don't mean to make any kind of arrangement?"

"I am willing to make one concession," Mr. Toke replied. "As I assume
that you bought the clock for the purpose of recovering the jewels, I am
ready to take it back at the price that you paid, subject to its being in
the same condition as when it was sold."

"Well," said Hughes, "I suppose we must be thankful for small mercies. We
don't want to drop a couple of hundred on an empty shell. I will accept
your offer. The clock shall be delivered here in good condition next
Tuesday, if that will suit you."

"It will suit me perfectly," replied Mr. Toke. "And as to payment? Will a
crossed cheque do?"

"Certainly," Hughes replied; and, for the first time, his rather
unprepossessing countenance was illuminated by the ghost of a smile.

Mr. Toke was secretly surprised, but he concealed the fact and rejoined:

"One naturally prefers to draw crossed cheques. Shall I give the cheque
to the person who delivers the clock?

"No," replied Hughes. "I will come with it, or soon after."

Mr. Toke nodded, and, as the other rose to depart, said facetiously, and
perhaps a little untactfully:

"I am sorry that things have turned out so unsatisfactorily for Mr.
Dobey; but, if he had brought his heirlooms to me, instead of hiding them
in a clock in someone else's house, we might have made some mutually
satisfactory arrangement--that is, if he wished to dispose of them. You
might mention the fact to him for his future guidance."

It was not a tactful thing to say, under the circumstances, and, for a
moment, Mr. Hughes looked decidedly vicious. But, if he was an angry man,
he was also a politic man. He was not going to let temper stand in the
way of self-interest. Just as the great difficulty of the murderer is the
disposal of the body, so the great difficulty of those who acquire
unlawful goods is the disposal of the loot. Now Mr. Toke undoubtedly had
the means of disposing of valuable property. Mr. Hughes had not. For
though, like Mr. Toke, he knew the ropes, there were circumstances that
hindered his appearance in the places where precious things were bought
and sold. Therefore, to Mr. Toke's surprise, instead of resenting the
advice, he replied, dryly:

"He will be grateful for the tip. Shall I tell him that you are prepared
to waive the question of title deeds?"

Mr. Toke smiled blandly. "When I am offered property for purchase," he
said, "I assume that the vendor is the owner. It is a reasonable
assumption."

"Quite," agreed Hughes. "But suppose there seems to be a flaw in the
title. How would that affect the transaction? I suppose it would be a
case of a knock-down price, at any rate?"

"My dear sir," said Mr. Toke, "you know very well that property which is
hampered by conditions that hinder its sale in the open market is of less
value than property not so hampered. That has to be allowed for in order
to leave a reasonable profit to the purchaser. But the allowance need not
be excessive."

Hughes reflected with a calculating eye on Mr. Toke. After a considerable
pause, he said, rather suddenly:

"Look here, Mr. Toke. I want to ask you a plain question. I don't know a
great deal about Dobey's affairs, but I fancy that he sometimes comes by
oddments of property--jewellery, for the most part--that are not quite
negotiable in the regular markets. I don't know where he picks them up.
It isn't my affair. Now the question is, in plain language, would you be
prepared to take them off his hands and give him a fair price for them?"

"If I bought them, I should give a fair price, allowing for difficulties
of disposal. But I couldn't have Dobey coming here, you know, or at my
private house."

"I realize that," said Hughes. "But that could be arranged. May I take it
that you would be willing to buy the goods and ask no questions?"

Mr. Toke was a little staggered by the bluntness of the phrase, but he
answered with belated caution:

"My business, hitherto, has been of a strictly legitimate kind. My
reputation in the trade is spotless. Still, if the affair could be
arranged with absolute discretion, I might be prepared to consider a deal
of the kind that you propose."

"Very well," said Hughes, "I will tell Dobey. And, if he should happen to
pick up any chance trifles, we must consider how the negotiations could
be carried out."

With this Mr. Hughes took his leave and departed with very mixed
feelings. On the one hand, he was possessed by a murderous hatred of Mr.
Toke. That the latter had the diamonds--that he had quietly annexed the
product of an almost unique coup--he had no doubt. But he was equally
sure that Mr. Toke's position was impregnable. By no means that he could
think of could that discreet gentleman be made to disgorge. On the other
hand, much to his surprise, Toke seemed quite willing to act as a
receiver of stolen property. That was all to the good; for Toke would
probably pay better prices than the wretched pittances offered by the
regular "fences." And he would be much safer to deal with, provided the
transactions were kept on the discreet lines that both of them desired.
So Mr. Hughes was not displeased, especially as the arrangement promised,
sooner or later, to give him a chance to settle accounts with Mr. Toke.

The latter gentleman, left alone in his office, was also a little
surprised at himself. After years of blameless dealing, he had suddenly
proposed to embark on the perilous activities of the "receiver." Why this
sudden change of outlook? He was a little puzzled, though he dimly
perceived the explanation; which was, in reality, fairly simple. He had
dismounted the diamonds from their settings, and had made an estimate of
their marketable value. The amount that he could safely reckon on
pocketing by their sale came out at the highly satisfactory figure of
seven thousand pounds. Now, seven thousand pounds takes a great deal of
earning by legitimate industry. Naturally he was impressed by this "easy
money"--the immemorial lure that has drawn so many on to the broad road
that leadeth to destruction. But the really potent influence was the fact
that he was already in actual possession of stolen property, and making
preparations to dispose of it. The first step had been taken; and, in
taking it, he had made a curious discovery. He had discovered that, apart
from the attraction of easily won wealth, there was a certain element of
excitement and adventure in the acquirement and sale of illicit property
that was only feebly present in lawful dealing.

On the following Tuesday the clock was duly delivered, and Mr. Toke was
in the act of winding it when Mr. Hughes arrived. His greeting was not
effusive, nor was it in any way hostile. He merely stated that he had
come for the cheque.

"A crossed cheque, you said, drawn to your own name, I suppose?"

"Yes. Arthur Hughes."

Mr. Toke wrote out the cheque and handed it to Hughes with the remark:

"Well, you've got your money back, at any rate."

"Some of it," responded Hughes, adding: "Are you sure you won't
reconsider the other little matter?"

But Mr. Toke's heart was hardened. Already, in effect, he had his hand on
that seven thousand pounds.

"If you mean the problem of the alleged lost property in the clock," said
he, "I can only repeat that I know nothing about it, and that I am
profoundly sceptical as to its having been there, at any rate when the
clock came into my possession."

"Very well," said Hughes, "then we must leave it at that. And now as to
the other matter--the question of your negotiating some of Dobey's
unconsidered trifles. Have you considered the question of procedure?"

"In a general way," replied Mr. Toke. "In the interests of us both, we
must avoid jeopardizing my position as a reputable dealer. You realize
that?"

Hughes realized it perfectly. Not that he was in the least tender about
Mr. Toke's reputation in the abstract, but he saw clearly that a
reputable dealer could obtain, and pay, better prices than a common
fence. He said so, and Mr. Toke continued:

"To that end, there must be as little contact as possible. I can't have
Dobey coming here; and the less you come here, yourself, the better. We
must avoid leaving tracks."

"Certainly," Hughes agreed, "if you can see how to avoid leaving them."

"I think I can. We will go into that presently. But there is another
point. We shall simplify matters a great deal if we try to treat one
another quite fairly and honestly."

Mr. Hughes's thoughts turned, inevitably, towards the despoiled clock,
and he grinned openly and undisguisedly. Nevertheless, he assented to the
proposition. Mr. Toke observed and interpreted the grin, but continued
unabashed:

"What I mean is, that if the vendor and purchaser are each content with
actual, realizable values, contacts, even by post, will be reduced to a
minimum."

Hughes nodded with the air of one waiting for further details, and Toke
continued:

"Supposing, for instance, Dobey submits a parcel of goods with a
specified price. Now, if that price is a fair one it can be paid, and
there is the end of the matter. But if he makes an excessive claim, the
goods must be returned, or there must be a course of bargaining,
involving, in either case, an undesirable number of contacts. Or, if he
should submit a parcel for an offer, and I make such an offer as, in my
judgment, is the best that is practicable; if he accepts that offer
without haggling, again contacts are reduced to a minimum. You see my
point?"

"Yes, and I agree in principle. One can't do more until one sees how
things work out in practice. How do you suggest that samples should be
submitted? You don't want them left by hand, and the post is not very
safe--an accident is always possible. Have you any plan?"

"A simple method occurs to me," said Mr. Toke "It is this. On receiving
notice in some prearranged manner that a sample is to be delivered, I
draw my car up at night in a quiet place, opposite a blank wall, with the
doors locked, but the rear window open. I then leave it for a few minutes
unattended. It would be quite easy for a passer-by to drop a small parcel
in at the window unobserved and pass on. A few suitable localities could
be designated by numbers for greater safety in making arrangements."

Mr. Hughes considered this proposal, and, on the whole, approved.

"It would work all right," said he, "provided both parties keep to the
principle of a square deal. Otherwise, the party who dropped his goods
into the other man's window would take a biggish risk."

"Quite so," agreed Mr. Toke. "That is why I emphasized the necessity for
scrupulous fair dealing on both sides."

They spent some time in settling a few details and in arranging a simple
code for use in unavoidable letters. Then Hughes rose as if to depart.
But, as he was turning away from the table, he paused and then sat down
again.

"There is one little affair that we might settle as I am here," said he.
He unbuttoned his coat and from an inner pocket produced a little
wash-leather bag. From this he extracted a ring set with a single large
emerald and laid it down on the table.

"Any offers?" he asked.

Mr. Toke took it up and examined it.

"A fine stone," he remarked, approvingly; "a very fine stone. Well cut,
too. These step-cut stones often have the table too large. I can offer
you thirty pounds for this ring."

"It is worth a good deal more than that," said Hughes.

"It is," agreed Mr. Toke. "It might fetch sixty at a suitable auction. I
will give you forty-five if I may sell it publicly and say where I got
it. Is that possible?"

"No," replied Hughes. "I am selling it on commission, and I don't know
where the vendor got it."

"Then," said Toke, "thirty is the outside price. You see, this is an
important stone. Someone is sure to have the particulars of it--the
measurements and weight--so it could be identified. If I take it, I
shall either have to have it re-cut or put it into store for a year or
two. Still, you might get a better price from someone else."

Hughes, however, knew that he certainly would not; having tried a fence,
who offered him ten pounds. But he did not mention this fact. He merely
replied:

"Very well. I suppose you know best. I'll take thirty, if you can't offer
any more."

Accordingly the amount was paid--in cash--and Mr. Hughes took his
leave.

We need not pursue the details of the subsequent transactions. The
visible parties to those transactions were Toke and Hughes; and, as both
of them were reasonable men, the necessary conditions were loyally
observed and everything went fairly smoothly. Toke made it a rule to give
the best prices that were economically possible; and these were so much
better than those obtainable from the regular fences that Hughes found it
practicable to purchase illicit goods from certain practitioners other
than Dobey, with the result that Mr. Toke was almost embarrassed by the
magnitude of the transactions. Yet it was all to the good. For the
increased amount of capital at his disposal enabled him not only to make
more important purchases in his own legitimate line, but to indulge in
the luxury, dear to the true collector's heart, of keeping specially
choice pieces which he would otherwise have had to sell.

But it had another effect; and a very queer effect it was. There was a
side to Mr. Toke's character which we have not had occasion to mention,
because, in the ordinary affairs of life, it did not show itself. But the
fact is, that there was in Mr. Toke's mental make-up a very definite
streak of the miser. It was very strange. In his daily business of life,
and even in his domestic affairs, he was a perfectly normal man, with a
banking account and investments, an ordered financial system, and a
completely rational sense of values. Yet, behind it all was that queer
mental twist; and, when it showed itself, Mr. Didbury Toke was a
miser--a genuine miser, too, of the real "Blackberry Jones" brand.

But perhaps it was not so very strange, after all. For Mr. Toke was a
born collector; and what is a miser but a collector of a rather
irrational kind? A collector whose joy is in mere possession, regardless
of the qualities--other than intrinsic value--of the things possessed?
At any rate, there it was; and it must be mentioned because certain
consequences, directly traceable to it, have to be recorded hereafter.
And, for the same reason, it is necessary to describe briefly the ways in
which this queer trait manifested itself.

In the good old days before the war, Mr. Toke was accustomed to keep, in
one of the rooms adjoining the gallery at the Manor House, in which his
collection was lodged, a drawer filled with sovereigns. It was a secret
hoard, not provided for current use, but, like the rest of the
collection, a treasure to be enjoyed by mere gloating and contemplation.
At night, when the gallery door was locked, he would bring it out and set
it on the table. Then, in the genuine "Blackberry Jones" manner, he would
sit himself down to gloat over its glittering contents, taking up
handfuls of the shining coins or spreading them out on the table in rows
or geometrical patterns.

Perhaps there was something to be said for this rather odd pursuit. The
Sovereign was a handsome coin, particularly as to the reverse, which
displayed Pistrucci's magnificent St. George. But, though Mr. Toke was
far from unappreciative of Pistrucci's masterpiece, it was not that work
of art which endeared the coins to his heart, as subsequent events
proved. For, in the days that followed the war, he was compelled to make
inroads on his treasure to carry out some of his foreign deals, and to
furnish himself for his journeys abroad. Gradually, the golden contents
of the drawer dwindled, until only a hundred or so of the coins were
left.

It was at this point that the inflow of ill-gotten wealth came to his
relief. The parcels of jewellery that Mr. Hughes dropped periodically in
through the window of his car consisted principally of "trade" articles,
which, however valuable intrinsically, were of no artistic merit. Mr.
Toke's procedure was to pick out the stones and dispose of them through
the ordinary trade channels. Their sale yielded him a modest profit, and
with this he was content, at least for a time. But presently the gold
mountings began to accumulate. If the transactions had been lawful ones,
be would simply have taken these mountings to a bullion dealer and
realized the value of the gold. But the gold mounts were precisely the
most recognizable parts of the "swag." It was quite impracticable to
dispose of them in the state in which they came to him.

Then he decided to melt them down; and, to this end, he provided himself
with a small crucible furnace that burned coke or charcoal--there was no
gas at the Manor House--and was fitted with a foot bellows. He also
obtained a few crucibles, one or two jewellers ingot moulds, and the
necessary tongs and other implements; and with these appliances he set to
work to reduce the miscellaneous collection of stoneless jewellery to
neat little ingots, each of which he carefully marked with a punch to
show its "fineness" in carats.

But even this did not quite solve the difficulty. For, as we have seen,
Mr. Toke was an eminently cautious gentleman, and it was borne in on him
that the sale of gold ingots on a somewhat considerable scale was a
proceeding that might, in the course of time, lead to inconvenient
enquiries. He was known as a dealer in stones. But gold ingots were
things that needed to be accounted for. He decided, at least for the
present, not to run the risk.

So, by degrees, the ingots accumulated. But Mr. Toke was not disturbed.
On the contrary, the larger his stock grew--and it grew apace--the less
desirous did he become to dispose of it. For a curious change had come
over him. Gradually, the affection that he had felt for the sovereigns
transferred itself to the growing pile of ingots; and at nights, when he
had turned out the surviving remnants of coins from the drawer, he would
bring forth the ingots from the cupboard where they were secreted and lay
them out on the table or build them up into little stacks. And as the
stacks grew steadily in size and number, he would think of his partners
and their mysterious activities with pleasant anticipations of yet
further additions to his hoard; which was rapidly becoming more real to
him than the less visible wealth that was represented by the figures in
his bank books and his lists of investments.

Occasionally he found himself speculating on the part that Mr. Hughes
played in this curious, unlawful business. Was he a receiver, pure and
simple, or was he an actual operator? On the rare occasions when they
met, Hughes maintained the most profound reticence. Mr. Toke's view was
that Hughes and Dobey formed a small firm to which Hughes contributed the
brains and power of contrivance, and Dobey the manual skill and executive
ability.

Possibly he was right. At any rate, as we have said, all went well and
smoothly, and Dobey, more fortunate than most of his fellow
practitioners, continued to keep out of the clutches of the law.

Chapter IV: Mr. Toke's Indiscretion

IN a remote corridor at the top of a large building in Holborn the rather
infrequent visitors might have seen a door, glazed with opaque glass, on
which was painted the name of Mr. Arthur Hughes. No further information
was vouchsafed; but if the directory had been consulted it would have
been ascertained that Mr. Hughes was a patent agent. His practice was not
extensive; but still, on certain rare occasions, stray members of that
peculiarly optimistic class, prospective patentees, discovered his
existence by means of the directory aforesaid, and subjected him to a
mild surprise by appearing in his office.

Their visits were not unwelcome; for, though the business that they
brought was of little enough value, they rendered possible the keeping of
books which could be produced in evidence of a bona fide industry.

The visitor, however, who appeared on a certain afternoon was not one of
these clients, nor was he connected with the patent industry; being, in
fact, none other than Mr. Didbury Toke. Mr. Toke was a good deal out of
breath, having climbed the long staircase as a matter of precaution, and
now sat panting across the table behind which Mr. Hughes was seated,
regarding him with undisguised impatience.

"It's a devil of a way up," said Mr. Toke.

"It is if you are fool enough to walk," was the ungracious reply. "Why
the deuce don't you use the lift?"

"Well," Mr. Toke explained, "one is apt to meet people in a lift, or at
least be seen and possibly remembered, by the lift girl, at any rate. It
is better to avoid contacts as far as possible."

"You're mighty careful," said Hughes, sourly. "You're glad enough to mop
up the profits of our little enterprises, but you don't mean to take any
of the risks."

"Not if I can help it," Toke admitted. "Why should I? And what good would
it be if I did?"

The question was so obviously reasonable (since the safety of each member
of the firm was essential to the well-being of the others) that Hughes
was reduced to a non-committal snort; and might have left it at that had
not Toke rather untactfully added: "And I am not aware that you are in
the habit of exposing yourself unnecessarily."

Mr. Hughes was apparently in a somewhat irritable state of mind, for he
took needless umbrage at this remark.

"Oh," he exclaimed, "so you think so, too, do you?"

"Too?" repeated Toke, interrogatively.

"Yes. You are taking up the same position as that infernal Dobey."

"I hope not," said Mr. Toke. "But what is Dobey's position?

"In effect the same as yours. He says that he takes all the risks while
we take most of the profits."

"I did not say that," Mr. Toke protested. "I admit that I keep out of
harm's way to the best of my ability. And, really, I suppose, as a matter
of fact, Dobey does take more risks than we do."

"Do you?" snarled Hughes. "How do you know what risks I take?"

Mr. Toke had to admit that he knew very little about the matter. "But,"
he continued, "there is no use in mutual fault-finding. We each have our
respective parts to play, and each of us is indispensable to the others."

"That isn't Dobey's view," said Hughes. "I have discovered that he has
been doing some jobs on his own, and what is worse, he has found some
other market for the swag. He is a slippery devil. Thanks to me, he has
been able to work in safety, and do uncommonly well. Now he thinks he
knows all there is to know, and he is going to work on his own and stick
to all the stuff that he collects--the ungrateful bounder!"

Mr. Toke expressed his profound disgust at this base conduct of the
unappreciative gas-fitter. "But, after all," he added optimistically, "I
suppose he is not the only pebble on the beach."

"No," Hughes admitted, "but he is a pretty big pebble, from our point of
view. We can't afford to lose his little contributions. But it is not
only that. Now that he seems to have gone off on his own, and knows that
I have spotted him, he may give us trouble, especially if he should get
into a tight place. As I said before, he is a slippery devil. But he had
better look out. If I see any signs of his making trouble, I shall make
things most unpleasantly lively for him. However, he hasn't starved us
out yet. I have got quite a nice little collection from another artist.
Got it here, too. I don't usually bring stuff to this place, but I had
to, on this occasion. So here it is, all ready for you to take away when
we have settled preliminaries."

"Oh, dear!" exclaimed Mr. Toke, "how very unfortunate! I can't possibly
take it now. I called to tell you that I am just starting on a longish
tour on the Continent."

"Well, you'll just have to put off the start for a day. I can't have the
stuff here, and I certainly can't store it while you are browsing about
the Continent."

"But," protested Mr. Toke, "I have made all my arrangements. I have shut
up the wing of my house where I keep my collection and sealed the doors,
and I have notified my solicitor that I have started."

"I suppose you can alter your arrangements if you please. You are your
own master."

Mr. Toke shook his head, and was about to add some confirmatory remarks
when Hughes suddenly lost what little patience he had and broke out,
angrily:

"Look here, Toke, you are going to take that stuff. You have got to. I am
not going to keep it in store for months. Besides, I want the money for
it. There is a hundred and fifty pounds' worth in this parcel. You can
look at it now, and, if you are afraid to take it away with you, I will
plant it in your car later."

"But," pleaded Toke, "I haven't got my car. I took it to the garage this
morning to be overhauled and taken care of while I am away. I should have
to go by train with the confounded stuff in a hand-bag."

Mr. Hughes was on the point of demanding what the occasion of the train
journey might be, seeing that the "stuff" was presumably to be deposited
either at Mr. Toke's bank or in his safe-deposit. That was how he had
always understood that Mr. Toke secured his valuables. But the reference
to the train journey seemed to offer a rather curious suggestion. And,
Mr. Hughes being a decidedly reticent, not to say secretive, gentleman,
refrained from either comment or question. But he stuck to his point, and
continued to insist that the property must be transferred. If he had done
so in a polite and tactful manner, all might have been well.
Unfortunately, he adopted a bullying, hectoring tone that jarred heavily
on Mr. Toke's already ruffled feelings. As a result, his customary
suavity gave place to a slightly forbidding manner.

"I think," he said stiffly, "you misunderstand the nature of our
relations. I purchase from you at my convenience. You are addressing me
as if I were some sort of subordinate, as you might address Dobey--who,
by the way, doesn't seem to have found your manners endearing."

"He will find them a good deal less endearing if, he doesn't take care,
and so will you. Don't you come here with your damned superior airs. You
are one of the firm, and I am the boss of the firm, and you have got to
understand that."

"And suppose I don't accept that relationship? Suppose I retire from the
firm, as you call it, and wash my hands of you? Would that suit you?"

"It wouldn't suit you if the police got to know that the eminently
respectable Mr. Didbury Toke had been doing a roaring trade in stolen
gems."

Mr. Toke's face hardened. "It is a great mistake to utter threats," he
said in a warning tone. And then, in total disregard of the admirable
principle that he had just laid down, he continued: "And, in fact, it
would not suit you particularly well if the police should be induced to
take an interest in you."

"But they couldn't," retorted Hughes. "You couldn't prove anything
against me. I've made it my business to see to that. In regard to this
swag, the man who collected it is at one end and the man who marketed
it--that's you--is at the other. I don't appear in it at all."

Mr. Toke smiled sourly. "I see," he said, quietly, "that you don't
remember me. But my memory is better."

"What the devil do you mean?" Hughes demanded angrily, but with a startled
expression which he failed to control.

"Of course," Mr. Toke continued, calmly, "I am a good deal changed. So
are you since the days when you used to have a sandy moustache and a
bushy head of hair. But, all the same, I recognized you at the first
glance." (Which was not quite correct. It had taken him some three months
to convert a vague sense of familiarity into a definite identification.)
"The sight of you carried me back to the time when I used to have
connections with the assaying industry, and when a good deal was heard
about a certain famous thumb-print."

He stopped rather abruptly--and wished that he had stopped sooner, as he
noted the effect of his foolish speech. Hughes did not trouble to contest
the statement, but sat gazing fixedly at the speaker; and the
concentrated malignity that expressed itself in that look brought Mr.
Toke suddenly to his senses. The gentle art of making enemies is an art
that is practised only by fools. But Mr. Toke was not a fool, and he
certainly did not want to make an enemy of Mr. Hughes. He saw clearly
that reconciliation was the necessary policy, and proceeded forthwith to
swallow his pride.

"This won't do, Hughes," he said in a conciliatory tone. "We are behaving
like a couple of fools. Of course we sink or swim together. I understand
that. I was annoyed at having my arrangements upset and lost my temper.
Let us have a look at that stuff."

Without a word, Hughes rose and walked across to a small safe which he
unlocked and threw open. From some inner recess in it he produced a
parcel which he laid on the table. Then he stepped over to the door, and,
having slipped the catch of the lock, came back and began methodically to
untie the string of the parcel. When the various wrappings were loosened,
there was exposed to view a miscellaneous collection of jewellery which
Mr. Toke diagnosed as probably the pooled swag from several different
robberies. He looked it over with tepid interest, being anxious chiefly
to get the business over and bring the rather unpleasant interview to an
end.

"Well," he said, "there's nothing sensational about it. You say you want
a hundred and fifty for this lot. It's quite enough, but it isn't worth
while to haggle over a trifle. I'll give you what you ask. I suppose a
cheque won't do for you?"

"No," Hughes replied gruffly, "of course it won't."

"It's infernally inconvenient," Toke grumbled. "This will eat up the
greater part of the cash that I had provided for travelling."

He produced a fat wallet from his pocket, and sorted out its contents; a
process that was watched by Hughes with a curious, avid interest as he
retied the string of the parcel.

"Fifteen tens," said Toke. "Will that do? I would rather keep the fives
for use on the road."

As Hughes made no reply, but silently held out his hand, Toke placed in
the latter the sheaf of crisp, rustling notes, and closed his wallet,
fastening it and returning it to his pocket.

"Now, Hughes," he said as he dropped the parcel into his hand-bag and put
on his hat, "let us forget the nonsense that we talked just now and bury
the hatchet. We shan't see each other again for a month or two. Don't let
us carry away unpleasant memories."

He held out his hand genially, and Hughes, relaxing with an effort the
grimness of his expression, took it and gave it a formal shake.

"I suppose," said he, "you will spend the night at Hartsden?"

"No," replied Toke, "I can't do that. I want to catch the night--or
rather early morning--train to Dover."

"You will have some trouble in making the various connections," Hughes
remarked. "There aren't so very many trains to and from Hartsden. It is a
pity that you didn't keep your car for another hour or two."

"Yes," Toke agreed reflectively. "I think you are right. The trains will
be an awkward complication. I rather think that I will just get the car
out again or borrow another. That will make me independent of trains."

"But what will you do with the car?" asked Hughes, who was beginning to
take an interest in Toke's movements.

"I dare say I shall be able to run it down to the garage. Or perhaps I
shall be able to get a taxi driver to run it round from the station. It
will only take him a few minutes."

"Yes," Hughes agreed, "that will be quite simple. And the car will enable
you to take your own time. Much better than the suburban trains. Well, so
long. I hope you will have a pleasant and profitable trip."

He gave a sort of valedictory grin--the nearest that he could get to the
semblance of a friendly smile--and accompanied Toke out into the
corridor, where he stood, watching the retreating figure of his associate
in iniquity. And, even as he looked, the grin faded from his features and
was replaced by a scowl of the most intense malice.

He went back into his office, still scowling forbiddingly, and with the
air of one wrapped in profound thought. Which was, in fact, his
condition. For Mr. Toke's indiscreet outburst had furnished him with the
matter for anxious cogitation. That Toke could or would "blow on" the
little transactions that took place between them had never occurred to
him. Nor did it now. He had made his position at least as safe as that of
Mr. Toke himself. Neither of them could effectively blow on the other.
But now it appeared that Mr. Toke could, by merely uttering a few words
in the proper quarter, send him, Mr. Hughes, to a term of penal
servitude. This was quite a different affair. The sudden appearance of
Mr. Toke as a potential accuser was, to put it very mildly, an extremely
disagreeable surprise. Up to this time, Hughes had believed that one
person only in the whole world had penetrated the very effective disguise
with which a natural affliction had furnished him as a free gift. For Mr.
Hughes's wig was, in any case, a necessity. An attack of the complaint
known as Alopecia areata had produced large bald patches which had to be
covered up by a wig; and this, together with the loss of his eyebrows,
and aided by the removal of his beard and moustache, had so metamorphosed
him that, though he avoided all old haunts and old acquaintances, he was
almost completely secure from recognition. But, as we have said, there
was one person who had appeared, at least, to suspect his identity, and
whose existence kept him in a state of constant watchfulness and anxiety.
And now there was another.

Mr. Hughes was not a scrupulous man; and if he was a cautious man, he was
ready to take a present risk for the sake of future safety. In the very
moment when Mr. Toke had foolishly proclaimed his power, he had made a
decision. He was not going to walk abroad with this everlasting menace at
his elbow. One dangerous enemy was more than enough. Two were more than
could be borne. The plain fact was that Mr. Toke knew too much; and that
fact pointed to the obvious remedy. So much Hughes had decided even while
Toke was speaking. The rest was only a question of ways and means.

Apparently, this question also was in course of being settled, for Mr.
Hughes, after pacing up and down the office for a few minutes, began, in
a leisurely and deliberate fashion, to make certain changes in his
visible characteristics that suggested a definite purpose. It is one of
the compensations of being compelled to wear a wig that one can choose
one's wig and even, on occasion, change it. Of this privilege Mr. Hughes
proceeded to avail himself. From a locked drawer in a locked cupboard he
took out a wig of a pronounced red and of a fluffy, rather ragged
texture, strikingly different from the sleek, dark brown one that he was
wearing. Having locked the door, he put on the new wig, and then produced
from the drawer a reddish moustache, a small bunch of hair of the same
colour, and a bottle of spirit gum. With some of the latter, he anointed
the base of the moustache (which was not one of those artless devices
used by the amateur actor, but a workmanlike affair, made by a regular
theatrical wig-maker) and carefully affixed it to his upper lip with the
aid of a small mirror.

When he had fixed it securely in position he cut off some wisps of hair
from the bundle, and, having stuck them along the upper margin of the
moustache, combed them over the latter and finally trimmed them off with
scissors. The effect was extremely realistic; and when, in the same way,
a pair of darkish eyebrows had been attached, the transformation was
complete.

But Mr. Hughes was too old a hand to trust a make up, no matter how
excellent, farther than was unavoidable. The afternoon was already
merging into evening. Another half-hour and the dusk would have fallen.
Then not even close inspection would penetrate the disguise. So Mr.
Hughes proceeded with caution. Having tidied up the office, he put away
the bottle and the other materials and appliances which he had been
using, and was in the act of locking the cupboard when he seemed to
remember something that he had forgotten, and hastily reopened the door.
Then that something was searched for and found in another locked drawer;
revealing itself as a sheath-knife of the kind used by old-fashioned
sailors (and commonly known as a "Green river knife"), furnished with a
narrow waist-strap. Having slipped the knife inside the waistband of his
trousers, he secured it in place by means of the strap. Then he took a
glance at a time table and jotted down a few figures on a slip of paper
which he put in his pocket, after which he walked over to the window and
stood for a while, looking down into the fast-emptying street.

Already the daylight was beginning to fade, and the quiet of evening was
settling down on the city. Judging that the time had come, he emerged
cautiously into the dim corridor, locked the door behind him and set
forth. Emulating Mr. Toke's discretion, he avoided the lift, taking his
way down the unfrequented staircase, from the bottom of which he hurried
along the lower corridors, and so out into the street. Even there he
preserved his attitude of caution, threading his way through the quieter
back thoroughfares, and maintaining that incessant watchfulness that has
to be habitual with those who are on unsatisfactory terms with the law.

By the time that he reached the station the daylight was visibly
weakening. He walked confidently to the booking-office, where he took a
first-class single ticket to Hartsden Junction, which, as he knew, was
some three-quarters of a mile from the hamlet which gave it its name. He
was by no means unacquainted with the locality, for, if the truth must be
told, he and Dobey had reconnoitred the neighbourhood with the idea of a
possible nocturnal visit to Mr. Toke's premises on some occasion when
that gentleman was absent on one of his periodical excursions abroad.
That visit had never been made, for the reason that Mr. Toke had let it
be very clearly understood that he kept on those premises nothing but the
"pieces" that formed his collection--porcelain figures, bronzes, and
other objects, valuable enough in themselves, but of no use to merchants
of the class to which Hughes and Dobey belonged. All negotiable property,
he had explained, was kept securely in the strong room of his bank or in
the safe that he rented at the safe-deposit establishment; and this had
seemed such an obvious precaution that both rascals had accepted the
statement and abandoned the idea of the nocturnal raid.

But now, by the light of the admission that Mr. Toke had so incautiously
made, that he was proposing to convey this parcel of stolen property to
his house, evidently with the intention of leaving it there during his
absence abroad, Mr. Hughes began to reconsider the situation. The main
object of his journey was not irreconcilable with certain other
transactions; and, as he was borne by the fast express to the
neighbourhood of Mr. Toke's residence, he turned over quite a number of
interesting possibilities.

The night had definitely fallen when Mr. Hughes approached the hamlet of
Hartsden by the road from the Junction. He looked about him with his
habitual wariness, but there was little need; for, as he passed through
the single street, not a soul was to be seen, and, but for the lighted
windows, the place might have been uninhabited. Beyond the hamlet the old
manor house stood in dignified isolation, and adjoining it was the
disused churchyard, enclosing the ruinous church--now also disused and
replaced by a new building at the other end of the village.

It was towards the churchyard that Hughes directed his steps, making for
the gateway without hesitation as if by a considered plan. On arriving
there, he paused for a moment to glance down the road--of which the
gateway commanded a clear view; then he pushed open the rickety gate and
entered. Slowly he walked along the narrow path that led to the church,
looking back from time to time to see that he still had an uninterrupted
view of the road. Presently the path turned slightly to the right, and,
passing into the shadow of a great yew tree, was encompassed by darkness
so complete that Hughes was able only with the greatest difficulty to
grope his way along it. Here, by the side of a large sarcophagus tomb
which stood between the yew tree and the wall, he stopped and looked
about him. Finding that the road was now no longer in sight, he slowly
retraced his steps until he was, able once more to look out through the
gateway along the road that formed the only approach to the village. And
here he selected a spot where he could keep a look-out, secure from the
observation of any chance wayfarer who might pass along from the village.

He was prepared for a long vigil, for it was possible that Toke might be
delayed; and, in any case, the car would take considerably longer to
cover the distance than the fast train by which Hughes had travelled. To
beguile the time, he produced his cigarette-case and took out a
cigarette. But his habitual caution warned him not to light it in view of
the road. Accordingly, he retired past the yew tree into the darkest
corner of the churchyard, behind the great tomb, and there, crouching low
against the plinth of the tomb, he struck a match, held it for a moment
to the cigarette and blew it out. But even then he held the cigarette
shrouded in his hand; and when he returned to his look-out, he was
careful to ensconce himself behind the tall headstone that he had
selected as cover so that the glow of the cigarette should not be visible
from outside.

But it was a tedious business, waiting in the gloom of the darkening
churchyard for the coming of the man who could send him to penal
servitude. And it was rendered none the more pleasant by a somewhat acute
anxiety. For, though he had a perfectly clear purpose, the carrying into
effect of that purpose could not be planned in exact detail. The precise
method of procedure must be determined by Mr. Toke's actions; and these
could not be foreseen.

Time ran on. One by one, the lights in the windows of the few houses that
were visible from the churchyard went out, and the chime of the clock in
the new church at the end of the village, borne faintly on the night air,
told out quarter after quarter. It was just striking the hour of ten when
Hughes, having lighted his sixth cigarette, came out from behind the
sarcophagus tomb and crept back to his look-out; and at that moment the
lights of a car came into sight far away down the road.

Hughes was not a nervous man. But the message that those glimmering
lights conveyed to him set his heart thumping and his hands trembling so
that the cigarette dropped unheeded from his fingers. It is one thing to
contemplate an atrocious deed from afar, but quite another to feel the
irrevocable moment of action drawing nigh. With a feeling of shuddering
dread, but yet never for an instant abandoning his dreadful intent, he
watched the lights gradually wax brighter until the approaching car was
actually entering the village. Apparently it was fitted with a powerful
but silent engine, for no throb or hum of mechanism was borne to his
ears.

Suddenly the lights went out, and for a few moments the car was
perceptible neither to eye nor ear. Then it became faintly visible as a
dim spot of deeper darkness. Nearer and nearer it came, now growing into
a defined shape, and recognizable as a large, closed car. Hughes craned
out from behind the headstone to watch it as it passed the gate. But it
did not pass the gate. Just as it reached the farther wall of the
churchyard, it slowed down suddenly and turned off to the left and was
instantly lost to view.

To Hughes, in his state of extreme nervous tension, this unexpected
behaviour was highly disconcerting. He had assumed that Mr. Toke would
drive up to his gate, get out, and open it, and then run the car up the
drive to the door of the house. Much puzzled and somewhat alarmed, he
crept out from behind the headstone and began to steal softly and
cautiously down the path towards the gate. But he had gone only a few
steps when he was startled by the sudden appearance of Mr. Toke within a
few paces of the gate and walking briskly towards it with the evident
intention of entering the churchyard.

Sweating and trembling from the sudden shock, Hughes staggered back to
the headstone and crouched down behind it, cursing silently and for the
moment overcome by terror. A step or two more and he must have been seen;
and who could say what would have happened then? Toke could hardly have
failed to grasp the situation; and Toke was no weakling. It had been a
near thing.

From his lurking-place he saw Mr. Toke, hand-bag in hand, walk up the
path with the assured manner of a man who is making for a definite
destination. When he had passed the headstone Hughes craned out to watch
the retreating figure; and, as it disappeared into the darkness under the
yew tree, he rose and followed stealthily, crouching low to keep out of
sight among the crowded tombstones. Presently he halted just at the edge
of the patch of shadow and watched from the shelter of a crumbling tomb
that was enclosed by an ivy-covered railing. From the impenetrable
darkness under the yew tree there came a faint grinding or creaking
sound. It lasted but a few moments, but, after a brief interval it was
repeated. After yet another short interval, Hughes rose and came out from
behind the railed tomb. Then he, too, disappeared into the darkness under
the yew tree.

The minutes passed, but no sound came from that eerie corner of the
churchyard over which the yew tree cast its sinister shadow. The clock of
the distant church told out a quarter and then another. The
reverberations of the bell had just died away when the silence was broken
once more by that curious faint grinding or creaking sound. It was
followed, almost immediately, by what sounded like a muffled cry. Again
there was a brief space of silence. Then the grinding sound was repeated.
And, after that, again silence.

The time ran on. Save for the murmur of the trees, as the leaves were
gently stirred by the soft breeze, and the faint, indefinite voices of
the night, not a sound disturbed the stillness that brooded over the
churchyard. Away in the distance, the clock of the new church made its
announcements to the sleeping village of the passage of the minutes that
perish for us and are reckoned. But among the grey headstones and under
the solemn yew tree, nothing stirred and no sound broke in to disturb the
peace of the dead.

So the time passed, measured out impassively, quarter by quarter, by the
distant chimes. More than an hour had slipped away since those two
figures had been swallowed up in the dark cavernous depths under the yew
tree, when the silence of the night was at last broken by the faint
grinding creak. After the lapse of a few seconds, it was repeated. Then a
figure appeared creeping stealthily out of the shadow and down the path
towards the gate, which, as it emerged into the dim light, revealed
itself as that of Mr. Hughes.

There was something curiously secret and furtive in his demeanour. He
walked slowly, setting down his foot at each step with evident care to
make no sound, and every few seconds he paused to listen and look about
him. Thus he crept down to the gate, where again he halted and stood,
listening intently and gazing into the darkness, first up the village
street, and then across at the old manor house, sleeping among its trees.
But it seemed that in the whole village there was no living creature
besides himself waking and moving.

From the gate he turned to the right, and, in the same silent, furtive
manner, stole along the wall of the churchyard towards the place into
which the car had seemed to disappear. Short as the distance was, it
seemed interminable in the agony of suspense that possessed him. For the
car was indispensable. It had been the keystone of his plan--the
appointed means of safety and escape. But suppose it had been seen, or,
still worse, taken away! The fearful possibility brought the sweat afresh
to his already clammy brow, and set his trembling limbs shaking so that
he staggered like a drunken man.

At length he reached the corner of the wall. Beside the churchyard ran a
narrow, leafy lane, enclosed between the high wall and a tall hedgerow,
and as dark as a cellar. He peered desperately into the dense obscurity,
but at first could see nothing. With throbbing heart he stole up the lane
as quickly as he dared, still craning eagerly forward into the darkness,
yet still careful not to trip on the rough ground. Suddenly he gave a
gasp of relief; for, out of the darkness ahead, a shape of deeper
darkness emerged, and, as he hurried forward, he recognized the big
covered car with which he had had so many dealings in the past.

Shaken as he was, he still had all his wits about him, and he realized
that there must be no false start. Once he was on the move, he must get
straight away from the neighbourhood. It would never do to be held up on
the road by any failure of the engine or other occasion of delay.
Accordingly, he went over all the working parts with the aid of a small
electric lamp that he produced from his pocket and satisfied himself that
all was in order. Then he threw the light back along the lane to see that
the way was clear for steering out in reverse. That was the immediate
difficulty. There seemed to be no room to turn round. He would have to
back out; and to back out at the first attempt.

At length he prepared for the actual start. Getting into the driver's
seat, he switched on the lights and the ignition and pressed the electric
starter. Instantly, the silence was shattered by a roar that seemed fit
to rouse the whole countryside, and brought the sweat streaming down his
face. Still, though the hand that held the steering wheel shook as if
with a palsy, he kept his wits under control. The lane was practically
straight and the car had been run straight in. By the dim light of the
rear lamp he could see through the rear window well enough to back the
car down the lane to the road.

At last, he was out in the open, as he could see by the light from the
front lamps shining on the corner of the churchyard wail. He put the
steering-wheel over and started forward, now quite noiselessly, through
the village street and so out on to the London road.

It was getting on for two o'clock when he drove into the small car-park
attached to the garage.

"Late, ain't you?" said the night watchman. "They told me Mr. Toke was
going to bring her back by half-past eleven. Did he miss his train?"

"No," replied Hughes. "He caught his train all right. It was my fault. I
had to go somewhere else and couldn't bring her along any sooner."

"Well," was the philosophical response, "better late than never."

"Very much better," Hughes agreed. "Good night--or rather, good
morning."

He paused for a moment to light a cigarette, and then walked out into the
street and was lost to sight.

BOOK II: INSPECTOR BADGER DECEASED

Chapter V: The Tragedy in the Tunnel

MR. SUPERINTENDENT MILLER was by no means an emotional man. He had his
moments of excitement or irritation, but in general he was a person of a
calm exterior, and gave the impression of one not easily ruffled. That
was my view of him, born of years of intimacy. But the Superintendent
Miller whom I admitted to our chambers in response to a somewhat
peremptory knock was a new phenomenon. His flushed, angry face and
lowering brow told us at once that something quite out of the ordinary
had occurred, and we looked at him expectantly without question or
remark. Nor was there any occasion for either; for, without seating
himself or even taking off his hat, he came instantly to the point.

"I want you two gentlemen to come with me at once, if you can. I've got a
car waiting. And I want you to bring all your wits and knowledge to bear
on this case as you never brought them before."

Thorndyke looked at him in surprise. "What is it, Miller?" he asked.

The Superintendent frowned at him fiercely, and replied in a voice husky
with passion: "It is Badger. He has been murdered. And I look to you two
gentlemen as officers of the law to strain every nerve in helping us to
bring the crime home to the villain who committed it."

We were profoundly shocked; and we could easily understand--and indeed
share--his wrathful determination to lay hands on the murderer. It is
true that Inspector Badger had been no favourite with any of the three of
us. His personal qualities had not been endearing. But now this was
forgotten. He had been, in a sense, an old friend, if at times he had
seemed a little like an enemy. But especially, he was a police officer;
and to a normally constituted Englishman, a police officer's life is
something even more sacred than the life of an ordinary man. For the
police are the guardians of the safety of us all. The risks that they
accept with quiet matter-of-fact courage are under taken that we may walk
abroad in security and rest at night in peace and confidence. Well may we
feel, as we do, that the murder of a police officer is at once an outrage
on the community and on every member of it.

"You may take it, Miller," said Thorndyke, "that we are at your command,
heart and soul. Where do you want us to go?"

"Greenhithe. That is where the body is lying and where the murder must
have been committed. There is a fairly good train in a quarter of an
hour, and the car will get us to the station in five minutes. Can you
come?"

"We must," was the reply; and without another word Thorndyke rose and ran
up to the laboratory to notify our assistant, Polton, of our sudden
departure. In less than a minute he returned with his "research case" in
his hand, and announced that he was ready to start; and as I had already
made the few preparations which were necessary, we went down to the car.

During our brief journey to the station nothing was said. As we arrived
at the platform from the booking office, the train came alongside, and
the passengers poured out. We took up our position opposite a first-class
coach, and, when the fresh passengers had all bestowed themselves and the
train was on the point of starting, we entered an empty compartment and
shut ourselves in.

"It is very good of you gentlemen," said Miller, as the train gathered
speed, "to come off like this at a moment's notice, especially as I have
not given you any inkling of the case. But there will be plenty of time
for me to tell you all I know--which isn't very much at present.
Probably we shall pick up some fresh details at Greenhithe. My present
information is limited to what we have heard over the telephone from
there and from Maidstone. This is what it amounts to.

"Yesterday morning poor Badger went down to Maidstone to look over
a batch of prisoners for the assizes and see if there were any old
acquaintances lurking under an alias. But principally his object was
to inspect a man who had given the name of Frederick Smith, but whom
he suspected of being a certain crook whose real name was unknown to
us. We were a good deal interested in this man. For various reasons
we associated him with a number of burglaries of a rather clever
type--one-man jobs, which are always the most difficult to deal with
if they are efficiently carried out. And we had something to go on in
one case, for Badger saw the man making off. However, he got away, and
neither he nor the stuff was ever traced. So our position was that here
was a man whom we suspected of quite an important series of crimes, but
who was, so to speak, in the air. He was not even a name. He was just a
'person unknown.' Whether we had his finger-prints under some name we
couldn't guess, because nobody knew him by sight excepting Badger; and
his opinion was that the man had never been in custody, and couldn't be
identified--excepting by himself."

"But," said I, "surely Badger could have put a description of him on
record."

"M'yes," replied Miller. "But you know what Badger was like. So beastly
secretive. One doesn't like to say it now, but he really didn't play the
game. If he got a bit of information, instead of passing it round for the
benefit of the force and the public, he would keep it to himself in the
hope of bringing off a striking coup and getting some kudos out of it.
And he did bring it off once or twice, and got more credit than he
deserved. But to come back to this Maidstone business. Badger gleaned
something from the reports concerning the prisoners there that made him
suspect that this man, Smith, might be the much-wanted burglar. So down
he went, all agog to see if Smith was the man he had once got a glimpse
of."

"I shouldn't think a recognition of that kind, based on a mere passing
glance, would have much value as evidence," I objected.

"Not in court," Miller admitted. "But it would have had considerable
weight with us. Badger had a devil of a memory for faces, and we knew it.
That was his strong point. He was like a snapshot camera. A single glance
at a face and it was fixed on his memory for ever."

"Do you know if he recognized the man?" Thorndyke asked.

"He didn't," replied Miller, "for the man wasn't there. In some way he
had managed to do a bolt; and up to the present, so far as I know, they
have not been able to find him. It is quite likely that he has got clean
away, for, as he was wearing his own clothes, he won't be very easy to
track. However, Badger seems to have satisfied himself that the man was
really the one he was looking for--probably he thought he recognized the
photographs--and this morning he started for Town with the papers--the
personal description, photographs, and finger-prints--for examination
and comparison at the Criminal Record Office. But he never arrived; and
about eleven o'clock his body was found near the middle of the Greenhithe
tunnel. The engine driver of an up train saw it lying across the rails on
the down side, and reported as soon as he got into Greenhithe. But it
seemed that at least one train had been over it by then. I gather
that--but there! I don't like to think of it. Poor old Badger!"

"No," Thorndyke agreed sympathetically. "It is too horrible to think of.
But still, as we have to investigate and ascertain what really happened,
we must put aside our personal feelings and face the facts, terrible as
they are. You spoke of his having been murdered. Do you know if there
were any signs, apart from the mutilation caused by the train passing
over him, that he had met a violent death? Is it clear that it was not an
accident?

"Quite clear, I think," replied Miller. "I know nothing about the
condition of the body, but I know that there was no open door on the off
side of the train that he travelled by."

"That would seem to be conclusive," said Thorndyke, "if the fact can be
established. But it isn't always easy to prove a negative. A passenger,
getting into an empty compartment and finding the door open, would
naturally shut it and might not report the circumstance. The point will
have to be enquired into."

"Yes," Miller agreed; "but I don't think there is much doubt. You must
remember that the train passed through Greenhithe station and past the
signal boxes both there and at Dartford. An open door on the off side
would be very noticeable from the down platforms. Still, as you say, the
point will have to be settled definitely. Probably it has been by now. We
shall hear what they have to say when we get to Greenhithe. But for my
part I have no doubt at all, door or no door. Badger was not the sort of
fool who leans out of the window of a moving train without seeing that
the door is fastened. It is a case of murder, and the murderer has got to
be found and dealt with."

If the Superintendent may have seemed to have formed a very definite
opinion on rather slender evidence, that opinion received strong
confirmation when we reached Greenhithe. Awaiting us on the platform were
a detective sergeant and one of the senior officers from Maidstone
Prison. They had travelled up from Maidstone together, apparently
comparing notes and making enquiries by the way.

"Well, sir," said the Sergeant, "I think we can exclude the suggestion of
accident, positively and certainly. It was unlikely on the face of it.
But we have got some definite facts that put it out altogether. This
officer, Chief Officer Cummings, whose duties include all matters
relating to descriptions and records, handed to Inspector Badger the
papers relating to the prisoner, Frederick Smith--finger-prints,
description, and photographs--and saw him put them into his letter
wallet. Now, I have been through that wallet with the greatest care, and
there is not a trace of any of those papers in the wallet or in any of
his pockets."

"Ha!" exclaimed Miller in a tone of grim satisfaction, "that settles it.
I take it, Cummings, that there is no possible doubt that the Inspector
had those papers in his pocket when he started from Maidstone?"

"Not a shadow of doubt, sir," replied Cummings. "I gave him the papers,
carefully folded, and saw him put them into his wallet--just into the
open wallet, as they were too large to go into the pockets without
further folding. He stowed the wallet away in his inside breast pocket
and buttoned his coat. And I can swear that it was in his pocket when he
started, for I walked with him to the station and actually saw him into
the train. He asked me to walk down with him, as there were various
questions that he wanted to put to me respecting the prisoners,
especially this man, Smith."

"Yes," said Miller, "we shall have to have a talk about Mr. Smith
presently. But the fact that the Inspector had those papers on his person
when he got into the train, and that they were not on the body, makes it
certain that he was not alone in the carriage."

"It does, sir," the Sergeant agreed. "But apart from that, we have got
direct evidence that he was not. The station-master at Strood gave us the
particulars. The Inspector's train stopped there, and he had to get out
and wait a few minutes for the London train. The station-master saw him
standing on the platform, and, as they knew each other, he went up to
him, and they had a few words together. While they were chatting the
London train came in and drew up at the platform. Inspector Badger was
just moving off to find a compartment when a man came along from the
entrance. As soon as the Inspector saw this man, he stopped short and
stood watching him. The man walked rather quickly along the train,
looking in at the windows, and got into an empty first-class smoking
compartment. But the station-master noticed that, before he got in, he
looked into each of the adjoining compartments, which were both empty. As
soon as he had got in and shut the door after him, the Inspector wished
the station-master 'Good morning,' and began to saunter slowly towards
the compartment that the stranger had got into. A few paces away from it
he stopped and waited until the guard blew his whistle. Then he walked
forward quickly and got into the compartment where the strange man was."

"Could the station-master give you any description of the man?"

"No, sire No description that would be of any use. He said he was a
middle-aged man of about medium height, not noticeably stout or thin,
moderately well-dressed in a darkish suit, and wearing a soft felt hat.
He thought that the man had darkish red hair and rather a red nose. But
that isn't very distinctive. And he thought he was clean-shaved."

"Did you ask him if he would know the man again if he saw him?"

"I did, sir, and he said that he might or he might not, but he didn't
think he would, and he certainly wouldn't swear to him."

The Superintendent emitted a growl of dissatisfaction, and, turning to
the Chief Officer, asked: "What do you say, Cummings? Does the
description suggest anything to you?"

The officer smiled deprecatingly. "I suppose, sir, you are thinking of
Frederick Smith, and it does seem likely. Smith certainly has darkish red
hair and a reddish nose. And he is about that age and about that height
and he hasn't got a beard, and when I last saw him he was wearing a
darkish suit and a soft felt hat. So it might have been Smith. But as the
description would apply to a good many men that you might meet, it isn't
much good for identification."

"No," growled Miller, "not enough details. And now that the finger-prints
and detailed description are gone, it might be difficult to prove his
identity even if we should get hold of him."

"It isn't as bad as that, sir," said Cummings. "As it happens, luckily, we
have a duplicate of the finger-prints, at least of some of them. The
officer who took the finger-prints made rather a mess of one of the
rolled impressions. So he had to waste that form and start over again.
Fortunately, the spoiled form wasn't destroyed. So we've got that, and of
course we've got the negatives of the photographs, and the officer who
took the description can remember most of the items. There will be no
difficulty in proving the identity if we can get hold of the man. And
that ought not to be so very difficult, either. There are several of us
who have seen him and could recognize him."

The Superintendent nodded. "That's all to the good," said he; "but before
we can recognize him we've got to find him. The train didn't stop here, I
understand."

"No, sir," the Sergeant replied. "The first stop after Strood was
Dartford. We've been over there, but we had no luck. There were a lot of
people waiting for the train, so the platform was pretty crowded, and it
was not easy to see who got out of the train. None of the porters noticed
any first-class passengers getting out, though there must have been one,
for a first-class ticket was collected--from Maidstone."

"Maidstone!" exclaimed Miller. "Well, that couldn't have been our man. He
came onto the Strood platform from the entrance."

"So the station-master says. But the booking-office clerk there doesn't
remember issuing any first-class ticket, or any ticket at all to
Dartford."

"Hm," grunted Miller. "Looks rather as if he didn't get out at Dartford.
May have chanced it and gone on to London. We must have all the tickets
checked. Did you make any enquiries from the ticket collector?"

"Yes, sir. But it was no go. He hadn't noticed any of the passengers
particularly. Two or three of the men who passed out answered the
station-master's description more or less. Of course they would. But he
didn't really remember what any of them was like, and he couldn't say
whether either of them was a first-class passenger. I suppose he just
looked at the tickets and didn't see anything else."

"Yes," Miller agreed. "But we will go into this matter presently. We
mustn't keep these gentlemen waiting." He turned to Thorndyke and asked:

"What would you like to do first, Doctor? I suppose you will want to
inspect the tunnel, and I should like you to take a look at the body."

"The body has been examined, sir," said the Sergeant, "by one of the
local doctors. He was rather cautious in his opinions, but I understood
that he found no marks of violence--no wounds or injuries excepting the
accidental ones."

"Where is the body?" the Superintendent asked.

"In an empty store, sir, down below. They put it there out of sight until
it could be moved to the mortuary."

Miller looked at us enquiringly, and Thorndyke reflected for a few
moments.

"I think we had better take the tunnel first and see if we can pick up
any traces from which we can gather a hint. It isn't very likely. The
inside of the carriage, if we could have identified and examined it,
would have been more hopeful as a source of information. However, the
carriage is not available and the tunnel is. Will it be safe to explore
it now?"

As he asked the question he glanced at the station-master, who took out
his watch and consulted it.

"There is a down train due in a couple of minutes," said he. "We had
better let that go through. Then the line will be clear for a full hour
on the down side."

"You have pretty long intervals," Miller remarked.

"We have," the station-master admitted, "but they will be a good deal
shorter when the electrification is completed. At present only the steam
trains come on from Dartford. There goes the signal."

We waited until the train had drawn up at the platform, discharged its
two or three passengers and proceeded on its way. Then we walked on to
the end of the platform, descended to the permanent way, and, marching in
a procession, headed by the station-master, along the rough side-path,
presently entered the mouth of the tunnel, advancing along the space
between the down-side rails and the smoke-blackened wall.

There is always something rather eerie about a tunnel, even a
comparatively short and straight one like that at Greenhithe, in which
the light is never completely lost. It is not the obscurity only or the
strange reverberating quality that the vaulted roof imparts to the voice.
The whole atmosphere is weird and uncanny, there is a sense of remoteness
from the haunts of living men, heightened by the ghostly, whispering
sounds which pervade the air, confused and indistinguishable echoes from
the far-away world of light and life.

The light from the entrance followed us quite a long way, throwing our
indefinitely elongated shadows into the twilight before us until they
were lost in the deeper gloom ahead. Gradually, the warm glow of the
station-master's lantern and the whiter circles of light from the
electric lamps carried by Thorndyke and the Superintendent replaced the
dwindling daylight and told us we were approaching the middle of the
tunnel. The combined lights of the three lamps illuminated the ground
with a brilliancy that was accentuated by the encompassing darkness,
lighting up the rails and sleepers and the stones of the ballast, and
bringing into view all the little odds and ends of litter that had been
jettisoned from passing trains; scraps of newspaper, match-boxes, spent
matches, cigarette-ends--trivial by-products of civilized human life,
insignificant and worthless, but each scanned attentively by six pairs of
eyes.

It was in the heart of the tunnel that Miller remarked, in a hollow voice
with an accompaniment of chattering echoes:

"Someone has chucked away a pretty good cigar. Shocking waste. He hasn't
smoked a quarter of it."

He spoke feelingly, for it was just the type of cigar that he favoured: a
big, dark-coloured cigar of the Corona shape. Thorndyke let the light
from his inspection lamp fall on it for an instant, but he made no reply,
and we continued our slow progress. But, a few moments later, I suddenly
missed the light from his lamp (we were marching in single file and he
brought up the rear of the procession), and, looking round, I saw that he
had gone back and was in the act of picking up the cigar with his gloved
left hand. As he evidently did not wish his proceedings to be noticed by
the others, I continued to walk on at a slightly reduced pace until he
overtook me, when I observed that he had carefully enclosed the cigar in
two of the seed envelopes that he invariably carried, and was now
tenderly wrapping it in his handkerchief before disposing of it in his
breast pocket.

"Any special significance in that cigar?" I asked.

"It is impossible to say," he replied. "A half-smoked cigar must have
some significance. It is for us to see whether it has any significance
for us."

The answer was a little cryptic and left me with the suspicion that it
did not really disclose the motive for his evidently considered act. To
one unacquainted with Thorndyke and his methods of research, the salving
of this scrap of jetsam must have appeared entirely foolish, for there
seemed no more reason for taking and preserving this cigar than for
collecting the various empty match-boxes and cigarette that lay strewn
around.

But I knew Thorndyke and his ways as no one else knew him. I knew that it
was his principle to examine everything. But the word "everything" has to
be construed reasonably. There was always some selection in the objects
that he examined; and I had the feeling that this cigar had presented to
him something more than its mere face value.

So I reflected as we walked on slowly, scanning the ballast by the light
of our lamps. But no other object came into view to engage our attention
until we reached the spot where the tragedy had occurred. Here we halted
with one accord and stood looking down in silence at the gruesome traces
of the disaster. Miller was the first to break the silence.

"There seems to have been a lot of blood. Doesn't that suggest that he
was alive when the train went over him?"

"Yes," replied Thorndyke, "in a general way, it does. But we shall be
able to judge better from an examination of the body." Then, turning to
the station-master, he asked: "How long could he have been lying on the
line when the down train came along?"

"Not more than a minute," was the reply. "Perhaps not that. The two
trains passed in the tunnel."

"And how was the body lying? You came with the search party, I think?"

"Yes, I directed the search party. The body was lying across the rails
slantwise with the feet towards the Greenhithe end. It was lying nearly
on its back. But, of course, the train passing over it may have changed
its position. Still, it is rather curious that the feet should have been
pointing that way. If a man steps out of a moving train, his feet come to
the ground and catch, and he flies forward head first. The position of
the body almost seemed to suggest that he fell out head downwards."

"Yes," agreed Thorndyke. "But there isn't much in it, for he certainly
did not step out. And a man who falls out by the unexpected opening of
the door may fall, in almost any position. Have you had any detailed
report from the driver of the down train?"

"Yes. I had a talk with him when he brought the train back from New
Brompton. But he had very little to tell. He never saw the body at all,
and he wouldn't have known of the accident if it hadn't been for the
chance that the fireman happened to look over the near side of the
foot-plate and caught just a passing glimpse of a pair of feet sticking
out from under the engine. He shouted out as soon as he saw them, but of
course there was nothing to be done. It was a fast train, and it couldn't
have been pulled up in its own length, even if that would have been any
good."

"And where did he pass the up train?"

"He was just passing the rear of it when the fireman shouted."

"Did he notice any open door?"

"No. But that is not to say that there was not an open door. He didn't
really see the other train at all. They had just opened the furnace door
and the light from that must have dazzled him. It was the light from the
furnace reflected from the roof and walls of the tunnel that enabled the
fireman to see the body."

"It is unnecessary to ask in what part of the train Badger was
travelling," said Thorndyke. "He must have been near the front unless it
was a very long train."

"It was rather a long train," said the Sergeant. "The station-master at
Strood told us that, though he couldn't say exactly how many coaches
there were. Of course, we can easily find out, and we shall have to. But
he was able to tell us where Inspector Badger's compartment was. It was
right up in front, in the second coach--rather an unusual position for a
first class compartment."

While this interrogation was proceeding, we had been walking on slowly
towards the east end of the tunnel, scrutinizing the ground as we went
but without any further result. We now came out into the open in a
cutting, and, on the station-master's advice, continued our examination
of the permanent way as far as Swanscombe Halt; but nothing came into
view that threw any light on the tragedy. At the halt we waited a few
minutes for an up train that was then due, in which we travelled back to
Greenhithe; an arrangement that not only saved time and effort, but gave
Thorndyke the opportunity of observing, with his head out of the window,
the conditions of light prevailing in the tunnel and the visibility of
one part of the train from the others.

As we came out on to the platform at Greenhithe, Miller looked wistfully
at my colleague.

"Did you think of having a look at the body, Doctor?" he asked, adding:
"I should feel more satisfied if you would. A local doctor hasn't had the
experience of criminal cases that you and Dr. Jervis have."

"I don't suppose that the local doctor would have missed any signs that
bore on the cause of death," said Thorndyke. "But still, an additional
examination is at least an extra precaution. Perhaps the station-master
will direct someone to show us the way."

The station-master elected to show us the way himself, and preceded us
down the stairs. Reluctantly, I followed Thorndyke, leaving the others on
the platform and, as I descended the stairs, I was, for the first time in
my professional life, conscious of a shrinking repugnance to the
atmosphere of tragedy and death. After all, a doctor has his human
feelings. It is impossible to look on the mutilated corpse of an old
acquaintance as the mere "subject" of an investigation. But, as a matter
of fact, I took no part in the actual examination. I saw that the body
still lay on the tarpaulin-covered stretcher and that part of the
clothing had been removed, but I stood aloof by the door, leaving the
inspection to Thorndyke; who evidently realized my state of mind, for he
made his examination in silence and with no suggestion that I should join
him.

One thing, however, I did observe, and with considerable surprise. When
he had completed his examination of the body, he opened his research case
and took from it the portable finger-print outfit that formed part of its
permanent equipment. Taking out the ready-inked copper plate and a couple
of cards, he proceeded, in his neat, methodical way, to make a set of ten
prints, one of each digit.

"Why are you taking his finger-prints?" I asked. "Does anything hinge on
them?"

"Not at present," he replied. "But it is possible that some finger-prints
may be found; and, if they may be, it might be very important to be able
to say if they were or were not Badger's. So I am securing the means of
comparison while they are available."

Thus stated, the motive for the proceeding seemed reasonable enough; but
yet the explanation left me wondering if there was not something more
definite in Thorndyke's mind. And this vague suspicion was strengthened
when, as I helped him to repack the research case, I saw him deposit in
it, and pack with extreme care, the derelict cigar which be had picked up
in the tunnel. But I made no comment, and as the gruesome business was
now completed, I took up the research case and led the way out of the
store.

"Apparently," he said as we ascended the stairs, "the local practitioner
was right. There are no signs of any injuries that might have been
inflicted before he fell on the line. But one thing is clear. He was
certainly alive when the train ran over him and for at least a few
seconds after."

"Then," said I, "it might really have been an accident."

"So far as the appearances and condition of the body are concerned, it
might. But if there was another person in the compartment and that person
has not reported an accident, the probabilities are overwhelmingly in
favour of either a crime or what we may call an incriminating
misadventure."

"What do you mean by an incriminating misadventure?" I asked.

"I mean a misadventure which would probably not have been accepted as
such. Miller believes that the other passenger was the escaped prisoner,
Frederick Smith. Suppose that Miller is right. Suppose that Badger
recognized the man and tried to arrest him. That the man resisted and a
struggle occurred. I don't see why it should unless Badger had handcuffs
with him and tried to put them on. But suppose a struggle to have
occurred, in the course of which the door became unfastened and Badger
fell out. That would have been a pure misadventure. But it is not likely
that the man would have reported it, for he would realize the
improbability of his statement being believed. He would trust rather to
the probability of his presence in the carriage being unknown."

"I have no doubt that he would," I agreed, "and wisely, too. For no one
would believe his statement. He would be charged with murder and most
probably convicted. But you don't entertain the possibility of a
misadventure, do you?

"As a bare possibility, yes. But it is wildly improbable; and still more
so if those documents were really in Badger's pocket and have really
disappeared. That is a crucial point. For, if it is certain that they
were removed from the wallet, that is not only evidence of a conflict
having taken place, but suggests in the strongest possible way that
Badger had been rendered unconscious or helpless. But that suggestion at
once raises the question, How was he rendered unconscious or helpless?
The state of the body seems to exclude physical violence such as
throttling or a knock on the head. Yet it is difficult to think of any
other means."

"Very difficult," I agreed, "particularly in the alleged circumstances--the
casual and unexpected meeting of two men in a railway carriage; and
if one of those men was, as the theft of the documents seems to imply, a
man just escaped from prison, the difficulty is still greater. Such a man
would presumably, be unprovided with anything but his fists, indeed the
mystery is how he could have procured his ticket."

"Yes," Thorndyke assented, "that calls for explanation. But we must not
mix up hypothesis and fact. Miller assumes that the man was the prisoner,
Smith, and it is possible that he was. But we must not let that
possibility influence us. We have to approach the inquiry with a
perfectly open mind."

As he concluded, we came out on to the platform, where we found our
friends awaiting us. In a few words Thorndyke communicated to them the
results of his inspection, at which Miller was visibly disappointed.

"It is an extraordinary thing," said he. "Badger was a pretty hefty
fellow and a skilled wrestler and boxer. I can't imagine even a strong
man putting him out through the door unless he had disabled him first.
And, in any case, you would expect to find some signs of a scrap. Did you
propose to make any further examination?"

"It doesn't seem very necessary," Thorndyke replied. "But perhaps you
might like me to be present when the local doctor does the post-mortem.
There are other possibilities besides gross physical injury."

"That is what I was thinking," said Miller; "and I should be glad if you
could be present at the post mortem. Then I could feel satisfied that
nothing had been overlooked. I understand that the inquest is to be held
to-morrow afternoon at four o'clock and the post-mortem at two. Can you
manage that?"

"I shall have to, if you think it important," was the reply.

As Miller was making grateful acknowledgments, the station-master
approached to convey to us the welcome tidings that a fast train to
London was due in a few minutes.

"Are you coming back with us, Superintendent?" Thorndyke asked.

"I may as well," Miller replied. "The Sergeant will carry on with the
case, and I must set some inquiries going at the London end. And, by the
way, Cummings, are you returning to Maidstone to-day?"

"Yes, sir," answered the Chief Officer. "I shall take the next train
back."

"Then," said Miller, "you had better have those finger-prints of Smith's
photographed and send either the photographs or the original up to
Headquarters with the portrait photographs and the personal description.
See to it at once, for we may want the information at any moment. In fact
we want it now."

"Very well, sir," replied Cummings. "I expect the photographs have been
done already, but in any case, I will see that you get them some time
to-morrow."

The short remaining interval was occupied by Miller in the delivery of
detailed instructions to the Sergeant. Then the train came hissing into
the station, and Thorndyke, Miller, and I took our places in a
compartment to which we were escorted by our three coadjutors.

Chapter VI: Thorndyke examines his Material

ON the way up to Town little was said on the subject of our investigation
and that little was mainly contributed by Miller. Thorndyke, unwilling as
he always was to go far beyond the ascertained facts, maintained a
tactful reticence tempered by a sympathetic interest in the
Superintendent's comments and suggestions.

"What I can't understand," said Miller, "is how that fellow managed to
get Badger out of the door. It wouldn't be easy in the case of an
ordinary man, but in the case of a man like Badger--a trained police
officer and a pretty hefty one at that--it seems incredible."

"It would seem," I suggested, with little conviction, "that he must have
been taken unawares."

"But how could he?" retorted Miller. "He knew that he was shut in with an
escaped prisoner and that the other man probably knew that he knew it.
You can take it that Badger would have watched him like a cat with a
mouse. And the other fellow would have had to get the door open. That's
rather a noticeable proceeding. No; when you think of the circumstances,
it seems impossible that Badger could have been caught off his guard, and
in a tunnel, too, of all places. What do you say, Doctor?"

"I agree with you," replied Thorndyke, "that it seems impossible that
Badger could have been put out by mere physical violence."

"Are you quite sure that there were no signs of any injury? No bullet
wound or marks of a life-preserver or sand-bag, or anything of that
sort?"

"I think I can say positively," Thorndyke answered, "that there was no
bullet wound and no bruises on the head, though I shall examine the body
more minutely to-morrow when I attend at the post-mortem. As to a
sand-bag, that would probably leave no external marks. But it is an
infinitely unlikely weapon to be used in a railway carriage, even in a
tunnel. The carriage was presumably lighted like this one; and although
that lamp gives a mere glimmer, hardly visible in daylight, the carriage
would not be dark enough to make the use of a sand-bag practicable."

"No," Miller agreed, "it wouldn't. I was just feeling around for some
sort of explanation. What about chloroform? Have you considered that?"

"Yes," replied Thorndyke, "and I think we can exclude it. At any rate I
could discover no trace of it. But, as a matter of fact, it is really not
practicable to administer chloroform forcibly to a strong man. The whiff
from a handkerchief, producing instant unconsciousness, appertains to
fiction. In practice the forcible use of chloroform involves a rather
prolonged struggle, and results in very characteristic marks on the skin
around the mouth and nose. There were no such marks in this case, nor any
other signs what ever."

"Then," Miller rejoined disconsolately, "I'm done. There must be some
sort of explanation, but I'm hanged if I can think of one. Does anything
occur to either of you gentlemen?"

For my part, I was as much in the dark as the Superintendent and had to
admit it; and Thorndyke, as I expected, refused to commit himself to any
speculative opinions.

"There isn't much use in theorizing at this stage," said he. "We want
more facts, and we want confirmation of the assumptions that we have been
treating as facts. For instance, the identity of the man who was seen to
get into the carriage at Strood."

"M'yes," Miller agreed reluctantly. "I don't think there's much doubt,
but, as you say, a little direct proof would be more satisfactory.
Probably we shall get some more details in the course of a day or two.
Meanwhile, I'm afraid I've taken up a lot of your time to very little
purpose. We don't know much more than we did when we started."

"Apparently we do not," Thorndyke admitted. "But I don't regret the
expedition. It was desirable for our own satisfaction to go over the
ground at once and make sure that we had not missed anything."

"I'm glad you take that view, Doctor," said Miller, "but, all the same,
you've got mighty little for your pains; nothing, in fact, excepting what
you have gleaned from your examination of the body, and that doesn't seem
to help us much."

"It doesn't," Thorndyke agreed. "But we must not forget that negative
evidence has its value. The exclusion of one possibility after another
leaves us eventually with the one that has to be accepted."

Miller received this rather academic observation without enthusiasm,
remarking, truly enough, that the early stages of that sort of
investigation were apt to be a little discouraging. "Possibly," he added,
"some thing new may come out at the inquest, though it isn't likely. And
it is just possible that, when we get those finger-prints from Maidstone,
we may find that we are dealing with a known criminal. But even that
would not prove the fact of the murder."

"As to that," said I, "if it can be proved, as apparently it can, that
this man was alone with Badger in the compartment when the disaster
occurred, that will create a pretty strong presumption of murder."

"No doubt," agreed Miller. "But presumption is a different thing from
proof. If he should give a plausible account of an accident--such as
leaning out of the window of an unfastened door--we shouldn't believe
him, but we couldn't disprove his statement, and you might find it hard
to get a jury to convict. If there is any doubt, the accused is entitled
to the benefit of it. What we want is something in the way of positive
evidence; and all that we have got is that certain documents have
apparently been taken from the person of the deceased."

"I should call that pretty weighty positive evidence," said I,
"especially as the documents included the suspect's finger-prints and
description. What do you think, Thorndyke?"

"I think," he replied, "that we shall be in a better position to form
opinions after the inquest, when we shall know what facts are really
available. And, speaking of the inquest, Miller, what is to be done with
regard to notes of the evidence? Are you employing a shorthand reporter,
or shall I bring or send my own man?"

"I don't see that either is necessary," replied Miller. "We can get a
copy of the depositions if we want one."

"That may meet your requirements," said Thorndyke, "but it may not suit
me so well. I think I will send a reporter of my own, and you can have a
copy of the notes if you have any use for them."

The Superintendent accepted this offer with suitable acknowledgments, and
the subject dropped for the time. As the train moved out of London Bridge
Station, however, I ventured to raise another subject of more immediate
interest, at least to me.

"What are we going to do in the matter of food, Thorndyke?" I asked.
"Does Polton know when to expect us?"

"Obviously not," was the reply, "as we did not know ourselves. I told him
that we should get some food on the way, and I suggest that the Coffee
Room at the Charing Cross Hotel will be the best place to stoke up.
Perhaps the Superintendent will join us."

"Very good of you, Doctor," said Miller, "but I think I must get on to my
office to finish up one or two odds and ends. Possibly we shall travel
down together to-morrow, but, if not, we shall meet at the inquest. By
that time I shall probably have seen those finger-prints from Maidstone."

Accordingly, we separated at Charing Cross, Miller striding away towards
the entrance while Thorndyke and I made our way to the Hotel Coffee Room,
where, with one accord, we demanded whatever might be ready at the
moment. The long fast that our various activities had entailed had
disposed us both to find a better use for our jaws than conversation. But
as the entrée dish emptied and the level in the claret bottle sank, my
interest in our quest revived and I began cautiously to put out feelers.
It had been evident to me that Thorndyke was not prepared to accept
Miller's interpretation of the facts, and the question that I asked
myself--and by implication put to him--was, Had he any alternative
theory? But my feelers felt nothing but a steady, passive resistance to
discussion, which, however, was not entirely unilluminating; for long
experience of Thorndyke had taught me that when he was more than usually
uncommunicative, he had something up his sleeve.

Now, could he have anything up his sleeve on the present occasion? Was
there something that he had seen and the rest of us had overlooked?
Naturally, I could not be sure, but there had been so little to see that
it seemed hardly possible. His examination of the body could not have
yielded any fact that he had net disclosed. It was quite unlike him to
withhold any observed fact when he made a report. As I turned over the
events of the day, I could recall only two that seemed to involve any
obscurity or uncertainty. Thorndyke had taken the dead man's
finger-prints. I did not see why. But it was a simple and reasonable
proceeding and Thorndyke's explanation had seemed adequate. But was it
possible that he had something more definite in his mind?

Again, he had picked up a half-smoked cigar in the tunnel. That I could
make nothing of. I could imagine no possible bearing that it could have
on the case. The subsequent taking of the finger-prints suggested a
suspicion that the cigar had been smoked by Badger. But supposing it had?
What light could that fact conceivably throw on the crime? I could
perceive no relevancy at all. Nevertheless, the more I reflected on these
two incidents, the more strongly did I suspect that they were connected
with something definite in Thorndyke's mind; something connected with
Badger's finger-prints, or even with those of the other man--which
would, indeed, furnish highly relevant and important evidence.

That suspicion deepened when, on our arrival at our chambers, he made his
way straight up to the laboratory with an air of evident purpose. There
we found our laboratory assistant, Polton, apparently engaged in a
post-mortem examination of the dismembered remains of a clock. He greeted
us with a crinkly smile of welcome, and, scenting some more alluring
activity, abandoned the autopsy and slipped off his stool.

"Is there anything that you are wanting, sir?" he asked, as Thorndyke ran
a seeking eye along the shelves.

"Haven't we a holder for objects that are to be photographed?" Thorndyke
enquired.

"Yes, sir. The stand forceps," was the reply; and, opening a cupboard,
Polton produced an appliance somewhat like an enlarged edition of the
stage forceps of a naturalist's microscope--a spring holder supported on
a heavy foot and furnished with a universal joint. As Polton set the
appliance down on the bench, Thorndyke opened his research case, and,
taking from it the envelope containing the cigar, extracted the latter
with a pair of forceps and fixed it in the jaws of the holder, which
grasped it near the pointed end. Anticipating the next move, I repaired
to the cupboard and brought forth an insufflator, or powder spray, and a
wide-mouthed bottle filled with a fine, white powder, both of which I
placed on the bench without remark. Thorndyke acknowledged the attention
with a smile, enquiring:

"What are the odds that we draw a blank?"

"You are gambling on the chance of finding Badger's finger-prints?" I
suggested.

"It is hardly a gamble, as we don't stand to lose anything," he replied.
"But I thought it worth while to try. There is at least a possibility."

"Undoubtedly," I agreed. "And the probability is not so very remote. What
I don't see is the relevancy of their presence or absence. Does it matter
to us or to anybody else whether Badger was or was not smoking a cigar
when he met his death?"

"That question," he replied, "we may leave until we see what luck we
have. The might-have-beens certainly do not concern us."

As he was speaking, he filled the container of the spray with the white
powder, and, starting the bellows, blew a jet of powder on to the cigar,
turning the latter round by degrees until every part of it was covered
with a white film. Then, swinging up the arm of the holder until the
cigar was upright, he took a little box-wood mallet that Polton had
picked out of a rack and handed to him, and began rapidly and lightly to
tap the foot of the holder. As the slight concussions were transmitted to
the cigar, the film of powder on its surface crept gradually downward,
uncovering the dark body by degrees, but leaving a number of
light-coloured patches where the powder had adhered more closely. Slowly,
as the tapping continued, the loose powder became detached until only the
lightest dusting remained; and meanwhile the light patches grew more
distinct and defined, and began to show faintly the characteristic linear
patterns of finger-prints. Finally, Thorndyke blew gently on the cigar,
rotating it as before by means of the universal joint. And now, as the
last vestiges of the loose powder were blown away, the finger-prints--or
at least some of them--grew suddenly quite clear and distinct.

Polton and I pored eagerly over the curious markings (though it had been
almost a foregone conclusion that some finger-prints must appear, since
somebody had held the cigar in his fingers) while Thorndyke once more
opened his research case and took from it a couple of cards, each bearing
five finger-prints and each scribed with the name of Inspector Badger.
Laying the two cards on the bench beside the holder, he took a magnifying
glass down from a nail on the wall and carefully scanned through it first
the prints on the card and then those on the cigar. After several
prolonged comparisons he seemed to have reached a conclusion, though he
made no remark but silently handed me the glass.

I began with a thorough inspection of the prints on the cards. They were
beautifully distinct, having been skilfully executed with finger-print
ink, and showed, with the sharpness of an engraving, not only the
ridge-pattern but the rows of tiny white dots on the black lines which
represented the mouths of the sweat glands. When I had to some extent
memorized the patterns, I turned my attention to the cigar, selecting
first a rather large print which looked like that of a thumb. It was
slightly blurred as if the thumb had been damp, but it was quite legible;
and when I compared it with the two thumb prints on the card, I
recognized it pretty confidently as that of the left hand.

Having reached a positive result, I felt no further examination was
worthwhile. But before giving my decision, I handed the glass to Polton,
who took it from me with a crinkle of satisfaction and bent eagerly over
the cards. But I think he had already made his observations with the
naked eye, for, after a very brief inspection, he delivered his verdict.

"It's a true bill, sir." He pointed at the large print with a pencil and
added:

"That is Mr. Badger's left thumb."

"That was my opinion, too," I said in confirmation.

"Yes," Thorndyke agreed, "I think there is no doubt of it, though it will
have to be verified by a detailed comparison of the separate characters.
But it establishes a prima facie case. There are a number of other, less
distinct prints, but we need not examine them now. The important thing is
to secure a permanent record which can be safely handled. How many
photographs shall we want, Polton?"

"You will want to show every part of every finger-print free from
distortion," said Polton, stating the problem and slowly rotating the
cigar as he spoke. "Six photographs would do it at a pinch, but if it is
important, I should do twelve and make it safe. That would give you about
four views of each finger-print."

"Very well, Polton," said Thorndyke, "we will make twelve exposures. And
if you have the plates ready, we will get them done at once."

As the making of twelve exposures promised to be a tedious business and
my assistance was not required, I took one or two sheets of paper from
the rack, and, laying them on the work-bench, proceeded to occupy myself
usefully in drawing up a summary of the day's experiences and the facts,
such as they were, which had transpired during our investigations. But
they were few and apparently not very significant, so that I was not long
in coming to the end of my summary; when I laid down my pen and
transferred my attention to Thorndyke's proceedings.

It was evident that the discovery of Badger's thumb-print had not
exhausted his interest in the derelict cigar, for, as each negative was
developed and washed, he brought it to the bench, and, holding it over a
sheet of white paper under the lamp, scrutinized it through his lens and
compared it with the prints on the cards. I did not quite understand the
object of this detailed comparison, for the identification of the one
print had established the fact that the cigar had been smoked by Badger,
whatever the significance of that fact might be. The identification of
further prints seemed rather like flogging a dead horse. Eventually I was
moved to make a remark to that effect.

"That is true enough," said he, "but we have to get all the information
that our material will yield. As a matter of fact, I am not looking for
the remainder of Badger's prints; I am looking to see if there are any
prints which are not his."

"And are there?"

"Yes, there is at least one and a problematical second one, but that is
practically obliterated by the heat from the burnt end. The other is a
fairly clear print, apparently a thumb; and it is certainly not either of
Badger's thumbs."

"From which, I presume, you infer that the cigar was given to Badger by
someone else?"

"That is the reasonable inference; and as he was alone with another man
in the carriage, the further inference is admissible that the giver of
the cigar was that other man. That, however, is only a probability which
will have to be considered in relation to the other facts."

"Yes," I agreed. "It might have been given to him at Maidstone to smoke
in the train. I don't see how you are to prove either view, or that you
would be much forrarder if you did."

I was, in fact, rather puzzled by the intense interest that Thorndyke
displayed in this cigar. For, surely, nothing could be less distinctive
or more hopeless for purposes of identification than a commodity which is
manufactured in thousands of identical replicas. But as Thorndyke must
necessarily realize this, I could only suppose that there was some point
the significance of which I had overlooked; and with this probability in
my mind, I followed my colleague's proceedings closely in the hope that
the point which I had missed would presently emerge.

When the last of the negatives had been developed and examined, Thorndyke
took the cigar out of the holder and wiped it clean of all traces of the
powder.

"That," he remarked, "is the advantage of carrying out these
investigations ourselves. If Miller had seen those finger-prints, he
would have insisted on annexing the cigar to produce as an 'exhibit' at
the trial--if there ever is one. Whereas our photographs, properly
attested, are equally good evidence, and the cigar is at our disposal for
further examination."

The advantage was not very obvious to me, but I discreetly abstained from
comment, and he continued:

"It is a rather unusual cigar; considerably above the ordinary
dimensions. The part which remains is five inches and an eighth long.
Judging by the thickness--a full three-quarters of an inch--the
complete cigar was probably well over six inches in length. How much over
we can't say. There are some enormously long cigars made for civic
banquets and similar functions."

"No doubt," said I, "a cigar merchant could identify the type and give us
the actual dimensions."

"Probably," he agreed. "But it is enough for us to note that it was an
exceptionally large cigar and pretty certainly an expensive one. And
then, as if the size were not enough, there is the strength of the
tobacco. The appearance of the leaf tells us that it is an uncommonly
strong weed. Taking the size and the strength together, it would be
rather more than enough for an ordinary smoker."

All of this was doubtless true, but it seemed to have no bearing on the
question as to how Inspector Badger had met with his death. I was still
puzzling over Thorndyke's apparently irrelevant proceedings when I
received a sudden enlightenment. Having finished his examination of its
exterior, Thorndyke laid the cigar on the bench and with a long thin
knife, cut it cleanly lengthwise down the middle. The action set a chord of
memory vibrating, and incidentally engendered in me a desire to kick
myself. For, years ago, I had seen Thorndyke cut open another cigar.

"Ha!" I exclaimed. "You are thinking of that poisoned cheroot that Walter
Hornby sent you."

"That we inferred to have been sent by him," Thorndyke corrected. "We
were pretty certainly right, but we had no actual proof. Yes, it seemed
possible that this might be a similar case."

I looked closely at the cut surfaces of the two halves. In the case of
the cheroot, the section had shown a whitish patch where the alkaloid--it
was aconitine, I remembered--had dried out of the solution. But
nothing of the kind was visible in these sections.

"I don't see any signs of the cigar having been tampered with," said I.
"There doesn't seem to be any trace of a hypodermic needle, as there was
in the cheroot, or any crystals or foreign matter of any kind."

"As to the needle," said Thorndyke, "the heat and the steam from the
burning end would probably obliterate any traces. But I am not so sure of
the absence of foreign matter. There is certainly no solid material, but
the whole of the inside has a greasy, sodden appearance which doesn't
seem quite natural, and the smell is not like that of a normal cigar."

I picked up one of the halves and cautiously sniffed at it.

"I don't make out anything abnormal," said I. "It is devilish strong and
rather unpleasant, but I can't distinguish any smell other than that of
virulently rank tobacco."

"Well," said Thorndyke, "there is no use in guessing. We had better
ascertain definitely. And as the foreign matter, if there is any, appears
to be a liquid, we will begin by making an attempt to isolate it."

He glanced at Polton, who, having put the negatives to drain, had now
reappeared and was casting wistful glances at the divided cigar.

"Will you want any apparatus prepared, sir, or any reagents?" he asked.

"A fairly wide-mouthed ten-ounce stoppered bottle and some sulphuric
ether will do for the start," replied Thorndyke; and as Polton went to
the chemical side of the laboratory in search of these he laid a sheet of
paper on the bench, and, placing on it one of the halves of the cigar,
proceeded to cut it up into fine shreds. I took possession of the other
half and operated on it in a similar manner; and when the whole cigar had
been reduced to a heap of dark-brown, clammy "fine-cut" tobacco, we shot
it into the bottle, which Thorndyke then half-filled with ether.

"This is going to be a long job," I remarked, looking a little anxiously
at my watch. "This stuff ought to macerate for two or three hours at
least."

"We need not complete the examination to-night," Thorndyke replied,
reassuringly, as he gave the bottle a shake. "If we can decide whether
there is or is not any foreign substance present, that will be enough for
our immediate purposes; and we ought to be able to settle that in half an
hour."

Thorndyke's estimate seemed to me rather optimistic, unless--as I was
disposed to suspect--he had already decided that some foreign substance
was present and had formed some opinion as to its nature. But I made no
comment, contenting myself with an occasional turn at shaking the bottle
or prodding the mass of sodden tobacco with a glass rod.

At the end of half an hour, Thorndyke decanted off the ether--now
stained a brownish yellow--into a beaker which he stood in a pan of warm
water to hasten the evaporation, while Polton opened the windows and door
to let the vapour escape.

"It's an awful waste of material, sir," he remarked, disapprovingly. "We
ought to have done this in a retort and recovered the ether."

"I suppose we ought," Thorndyke admitted, "but this is the quicker way,
and time is more precious than ether. Dr. Jervis wants to get done and go
to bed."

As he was speaking, we all watched the beaker, in which the liquid
dwindled in bulk from minute to minute, growing darker in colour as it
grew less in volume. At length it was reduced to a thin layer at the
bottom of the beaker--less than half a teaspoonful--and as this
remained unchanged in volume, and the odour of ether became rapidly less
intense, it was evident that evaporation had now ceased. Thorndyke took
up the beaker, and, having smelled the contents, turned it from side to
side to test the fluidity of the liquid; which flowed backwards and
forwards some what sluggishly like a thinnish oil.

"What do you say it is, Jervis?" he asked, handing the beaker to me.

"Probably a mixture," I replied. "But it smells like nicotine and it
looks like nicotine, excepting as to the colour; and as it has been
extracted from a cigar, I should say that it is nicotine, stained with
colouring matter."

"I think you are right," he said, "but we may as well confirm our
opinions. The colour test will not answer very well owing to the
staining, but it will probably work well enough to differentiate it from
coniine, which it resembles in consistency, though not very much in
smell. Can we have a white tile, Polton, or the cover of a porcelain
capsule?"

From the inexhaustible cupboard Polton produced a small white, enamelled
tile which he laid on the bench, while Thorndyke picked up a glass rod
which he dipped into the liquid in the beaker and then touched the middle
of the tile, leaving a drop on the white surface.

"I have rather forgotten this test," said I, leaning over the tile, "but
it seems to me that this drop shows quite a distinct green tint in spite
of the staining. Is that what you expected?"

"Yes," he replied. "The green tint is characteristic of nicotine. Coniine
would have given a pink colour. But we had better try Roussin's test and
settle the question quite definitely. We shall want two test tubes and
some iodine."

While Polton was supplying this requisition, Thorndyke took up a clean
filter paper and laid it on the drop of liquid on the tile, which it
immediately soaked up, producing an oily spot of a distinct green colour.

"That," said he, "further supports the suggestion of nicotine. But it is
not conclusive in the way that a chemical test is."

Once more I had the feeling that he was flogging a dead horse, for there
seemed to be no reason whatever for doubting that the liquid was
nicotine. However, I kept this view to myself, taking the opportunity to
refresh my memory as to the procedure of Roussin's test, while Polton
followed the experiment with breathless interest.

It was quite a simple test. Into one test tube Thorndyke dropped a few
particles of iodine and poured on them a small quantity of ether. While
the iodine was dissolving, he poured a little ether into the other test
tube, and, with a pipette, dropped into it a few minims of the liquid
from the beaker. When the iodine was dissolved, he poured the solution
into the other tube. Almost immediately a brownish-red precipitate
separated out and began to settle at the bottom of the tube.

"Is that according to plan?" I asked.

"Yes," he replied. "The result is positive, so far, but we must wait a
few minutes for the final answer to our question. If this liquid is
nicotine, the precipitate will presently crystallize out in long, slender
needles of a very characteristic colour--ruby red by transmitted light
and dark blue by reflected light."

He stood the test tube in a stand, and, seating himself on a high stool,
proceeded to fill his pipe, while Polton stationed himself opposite the
test tube stand and kept an expectant eye on the little mass of sediment.
Presently I saw him pick up the magnifying glass, and, having drawn down
an adjustable lamp, make a closer inspection. For three or four minutes
be continued to watch the test tube through the glass, assisting his
observations by placing a sheet of white paper upright behind the stand.
At length he reported progress.

"It is beginning to crystallize--long, thin blue crystals."

"Try it against the light," said Thorndyke.

Very slowly and carefully, to avoid disturbing the formation of the
crystals, Polton lifted the tube from its stand and held it between the
lamp and his eye.

"Now they are red," he reported, "like thin splinters of garnet."

I took the tube from his hand and examined the growing mass of fine,
needle-like crystals, crimson against the light and deep blue when the
light was behind me, and then passed it to Thorndyke.

"Yes," he said when he had verified our observations, "that is the
characteristic reaction. So now our question is answered. The liquid that
we extracted from the cigar is nicotine."

"Well," I remarked, "it has been a very interesting experiment, and I
suppose it was worth doing, but the result is not exactly sensational.
Nicotine is what one might expect to extract from a cigar, though I must
say that the amount is greater than I should have expected, especially as
we haven't got the whole of it."

Thorndyke regarded me with an indulgent smile.

"My learned friend," said he, "has allowed his toxicology to get a little
rusty, and thereby has missed the point of this experiment. It is not a
question of quantity; there ought not to have been any nicotine at all."

As I gazed at him in astonishment and was beginning to protest, he
continued: "The nicotine that we dissolved out with the ether was free
nicotine. But there is no free nicotine in a cigar. The alkaloid is
combined with malic acid. If this had been a normal cigar, we should have
got no free nicotine until we had treated the cigar--or a decoction of
it--with a caustic alkali, preferably caustic potash."

"Then," I exclaimed, "this nicotine had been artificially introduced into
the cigar."

"Exactly. It was a foreign substance, although it happened to be a
natural constituent of a cigar. Probably it was injected into the open
end with a hypodermic syringe. But at any rate there it was; and I think
that its presence disposes of Miller's question as to how Inspector
Badger was put out of the carriage on to the line."

"You think that he was suffering from nicotine poisoning?"

"I have no doubt of it. We have seen that he smoked at least an inch of
this cigar. The cigar contained naturally anything up to 8 per cent of
combined nicotine, part of which would pass into the smoke. To this had
been added not less than half a fluid drachm of free nicotine. Now, when
we consider that the lethal dose of nicotine is not more than two or
three drops, and that more than that amount must have been contained in
the part that was burned, we are pretty safe in assuming that the smoker
would have been reduced, at least, to a state of physical helplessness."

"You have no doubt that he was alive when the train went over him?"

"No. But though he was undoubtedly alive, I think it quite likely that he
was moribund. He had apparently taken nearly, if not quite, the full
lethal dose."

"It is a little surprising," I remarked, "that he went on smoking so
long; that he did not grow suspicious, seeing that he knew who his fellow
passenger was, as apparently he did."

"I don't think it is very surprising," replied Thorndyke. "The procedure
had been so well calculated to avert suspicion. Let us suppose--as
probably happened--that the stranger produces a cigar-case. There are
two cigars in it--one, no doubt, bearing a private mark. The stranger
takes the marked cigar and holds out the case to Badger. Now Badger, as
we know, usually smoked a pipe, but he was very partial to a cigar, and
he preferred a strong one. He would certainly have taken the cigar and
would have been impressed by its strength. Probably, owing to the
presence of the free nicotine, the cigar would not have burned freely. He
would have had to draw at it vigorously to keep it alight, and so would
have drawn into his mouth a large amount of the vaporized nicotine.

"Presently he would begin to feel unwell, but at first he would feel
nothing more than ordinary tobacco-sickness, and before he had time to
become suspicious, he would be in a state of collapse. Nicotine, you will
remember, is probably, with the exception of hydrocyanic acid, the most
rapid of all poisons in its action."

"Yes; but if Badger was really in a moribund state, it would seem that it
was a tactical mistake to throw him out on the line. If the murderer had
simply sat him up in a corner and got out at the next station, no
suspicion of any crime would have arisen. The body might not have been
observed until the train reached London, and when it was discovered and
examined, death would have appeared to have been due to natural causes,
or to excessive smoking, if the nicotine poisoning had been detected."

"I don't think that would have done, Jervis," Thorndyke replied. "Your
plan would have involved too many contingencies. The next stop was at
Dartford--a fairly busy junction. Someone might quite probably have got
in there and seen the murderer getting out. And again, Badger might have
recovered. You can usually tell when a man is dead, but it is difficult
even for an expert to be certain that an insensible man is dying. No,
this man was taking no risks, or as few as possible. And he was a
desperate man. Probably, Badger was the only officer who knew him, and he
was aware of the fact. His safety depended on his getting rid of Badger."

"I gather," said I, "that you don't accept Miller's view as to the
identity of the other passenger. It struck me that he was rather jumping
at conclusions."

"He was, indeed," Thorndyke agreed, "in a most surprising manner for so
shrewd and experienced an officer. It was a positive obsession. I never
entertained the idea for a moment, for, apart from the total absence of
evidence, it bristled with impossibilities. The man was a runaway
prisoner. He was, it is true, wearing his own clothes, but he would
probably have no hat and his pockets would almost certainly be empty. How
could such a man have got a first-class ticket? And how could he have got
away from Maidstone to make his appearance so promptly at Strood? The
thing is inconceivable.

"But we had better adjourn this discussion. It is past midnight, and
Polton is yawning in a way that threatens us with the job of reducing a
dislocation of the lower jaw. The rest of the nicotine extraction can
wait till the morning, if it is necessary to pursue the question of
quantity. The actual amount is of no great consequence. The presence of
free nicotine is the essential fact, and we have established that."

"And thereby," said I, as the meeting broke up, "prepared quite a
pleasant little surprise for Superintendent Miller."

Chapter VII: The Persistence of Superintendent Miller

As I undressed, and for the short time that I lay awake, I revolved in my
mind the amazing events of the evening; and in the morning, no sooner was
I in possession of my waking senses than the question presented itself
afresh for consideration. What was it that had impelled Thorndyke to
secure and preserve that cigar? It had looked like a mere chance shot.
But all my knowledge and experience of Thorndyke and his ways was against
any such explanation. Thorndyke was not in the habit of making chance
shots. Moreover, the act had been deliberate and considered. He had seen
the cigar by the instantaneous flash of the lamp; he had walked on for a
few paces, and then he had slipped on a glove and gone back to pick up
the cigar and bestow it in his pocket with evident care. In those few
instants of reflection, something must have occurred to him to suggest
the incredible possibility that had been turned into ascertained fact in
the laboratory. Now, what could that something have been?

When we met at the breakfast-table, I proceeded without delay to present
my problem for solution.

"I have been wondering, Thorndyke," said I, "what made you pick up that
cigar. Evidently, the results of the examination were not entirely
unexpected."

I could see that my question, also, was not unexpected. But he did not
reply immediately, and I continued:

"That cigar was perfectly normal to look at. Yet it seems as if some
intuition had suggested to you the possibility of its amazingly abnormal
qualities. It is an utter mystery to me."

"I pray you, Jervis," he replied, smilingly, "not to accuse me of
intuitions. I have always assumed that intuitions are for those who can't
reason. But let us consider the circumstances surrounding that cigar. We
will take first the prima facie appearances, disregarding, for the
moment, our own personalities and our special knowledge and experience.

"Here was a cigar which had been lighted and thrown away, less than
half-smoked. Now, its condition offered evidence, at a glance, of some
sudden change in the state of mind of the smoker. That would be true even
of a cigarette. Normally, a man either wants a smoke or he does not. If
he does, he lights the cigarette and smokes it. If he does not, he
doesn't light it. But if he lights it and then throws it away, that act
is evidence of a change of purpose; and that change is almost certainly
determined by some change in his circumstances or surroundings.

"But what is true of a cigarette, which costs about a penny, is more
emphatically true of a cigar of an expensive type, which must have cost
at least half a crown. There must have been some definite reason for its
having been thrown away. But within a few yards of the place where the
cigar was lying, a man had been murdered. There had been two men in a
smoking-compartment. If deceased had been smoking a cigar, he would
obviously not have finished it; and the same is almost certainly true of
the other. Hence there was an appreciable probability that this cigar had
some connection with the murder. But, since a cigar which has been smoked
is practically certain to bear finger-prints, it would have been
reasonable in any case to secure the cigar and see, if possible, whose
finger-prints it bore.

"So much for the general aspects of the incident--which I should have
thought would have been obvious to Miller. We, however, were not
concerned only with the general aspects. We had special knowledge and
special experience. I have told you how, in the early days of my
practice, when I had little to do, I used to occupy myself in the
invention of crimes of an unusual and ingenious kind and in devising
methods of detection to counter them. It was time and effort well spent;
for each crime that I invented--and circumvented--though it was
imaginary, yet furnished actual experience which prepared me to deal with
such a crime if I should encounter it in real life. Now, among the
criminal methods which I devised was the use of a cigar as the means for
administering poison."

"Yes," said I, "I remember; and very fortunate it was for you that you
did. The fact that the possibility was in your mind probably saved your
life when our friend, Hornby, sent you that poisoned cheroot."

"Exactly," he agreed. "The imaginary case had the effect of a real case;
and when the real case occurred, it found me prepared. And now let us
apply these facts to the present case. You heard Miller's sketch of the
tragedy as he had heard it told through the telephone, and you will
remember that he put his finger on the point that most needed
explanation. How had Badger been put out of the carriage on to the line?
According to the report, no gross injuries had been found. He had not
been shot or stabbed or bludgeoned. He seemed simply to have been thrown
out. Yet how could such a thing be possible? A Metropolitan
police-officer is a formidable man, and Badger was a fine specimen of his
class--big, powerful, courageous, and highly trained in the arts of
offence and defence. He could not have been off his guard, for he knew
that he was travelling with a criminal and must have been prepared for an
attack. How then could he have been thrown out? That was Miller's
difficulty, and it was a real one, assuming that the report had given the
true facts.

"The train journey down gave us time to think it over. That time I
employed in turning over every explanation that I could think of. Since
direct violence seemed to be ruled out, the only reasonable supposition
was that, in some way, Badger must have been rendered insensible or
helpless. But in what way? You heard Miller's suggestions; and you could
see that none of them was practicable. To me, it appeared that poison in
some form was the most likely method. But how do you set to work to
poison a man in a railway carriage?

"I considered the various methods that were physically possible. The
most obvious was to offer a drink from a flask. That would be effective
enough--but not with a detective inspector of the C.I.D. Badger would
have refused to a certainty; and poisoned sweets would have been still
more hopeless. Then the possibility of a poisoned cigar occurred to
me. The idea seemed a little extravagant; but, still, the method had
actually been used within my own experience. And there was no denying
that it would have met the case perfectly. The offer of a cigar would
have appeared, even to a cautious police officer, a quite unsuspicious
action. And we know that Badger liked a cigar and would almost
certainly have accepted one. So, in spite of the fact that, as I have
said, the suggestion seemed rather far-fetched, I made a mental note to
keep the possibility in mind.

"At Greenhithe the absence of any traces of violence was confirmed. Then
we went into the tunnel; and behold! almost the first object that we
notice is a half-smoked cigar. There was not much need for intuitions."

I admitted a little shamefacedly that there was not. It was the old
story. An item of knowledge or experience that was once in Thorndyke's
mind was there for ever; and what is more, it was available for use at
any moment, and in any set of circumstances. I had not this gift. My
memory was good enough; but I had not his constructive imagination. I
could only use my experiences when analogous circumstances recurred. The
poisoned cheroot had come by post. Thereafter, I should have looked with
suspicion on any cigar that arrived by post from an unknown source. But
Thorndyke had the idea in his mind, ready to apply it to any new set of
circumstances. It was a vital difference.

Having settled this question, I passed on to another that had exercised
my mind a good deal.

"You seem," I said, "to have decided pretty clearly how the actual murder
was carried out. Have you carried the matter any farther? Have you any
theory of the general modus operandi of the crime?"

"Only in quite general terms," he replied. "I think we are forced to
certain conclusions. For instance, the fact that the murderer had the
poisoned cigar available compels us to assume that the crime was not only
premeditated but very definitely planned. My impression is that poor
Badger was under a delusion. He thought that he was stalking a criminal,
whereas, in fact, the criminal was stalking him. I suspect that he knew
what was going on at Maidstone, and that he kept Badger in sight. I
believe that he saw him into the train at Maidstone and travelled with
him in that train to Strood."

"There seem to be at least two objections to that theory," said I. "To
begin with, he could hardly have avoided being seen at Maidstone. For,
leaving Badger out of the picture, there was Cummings, who certainly knew
him by sight and would surely have spotted him at the station."

"I see," said Thorndyke, "that you are adopting Miller's view that the
murderer was the man Smith. That view seems to me quite untenable. I have
never entertained it for a moment."

"You are not forgetting the resemblance between the two men? That both
men had red hair and a noticeably red nose? It would be a remarkable
coincidence, if they were different men."

"Very true," he agreed. "But don't let us lose sight of the collateral
circumstances. If we assume that this was a carefully planned murder, as
it appears to have been, we have to be on the look-out for such ordinary
precautions as a murderer would probably take. Now a red nose with red
hair is a rather uncommon combination; and, as you say, its occurrence in
two men in these peculiar circumstances would be a remarkable
coincidence. But there are such things as wigs and rouge and
grease-paint; and these are just the circumstances in which we might look
to see them used. The very simplest make-up would do. Consider how easy
it would have been. Supposing a dark man with close-cropped hair gets
into an empty carriage at Maidstone. Just before reaching Strood, he
slips on a red wig and gives his nose an infinitesimal touch of rouge. On
arriving at Strood, he hops out, and at once makes for the stairs leading
to the subway. There, or elsewhere, he waits for the arrival of the
London train, and, when it comes in, he emerges, boldly, on to the
platform, and lets himself be plainly seen."

"But don't you think Badger would have spotted the wig?" I objected.

"I feel pretty sure that he would," Thorndyke replied. "But why not? The
stranger was there for the express purpose of being spotted. And you
notice a further use that the make-up would have had. For, after the
murder, he could have doffed the wig and cleaned off the rouge; and
forthwith he would have been a different person. The description of him,
as he had been seen at Strood, no longer applied to him. He could show
himself boldly at Dartford and leave no trace. What is the second
objection?"

"I was thinking of the fact--if it is a fact--that he took the risk of
stealing Smith's finger-print papers from the body. It was a very serious
risk. For if he had been stopped and searched and they had been found on
his person, that would have convicted him of the murder beyond any
question. And, moreover, the very fact that they were taken furnishes
evidence, of murder and effectually excludes the possibility of
misadventure. The taking of such a risk points to a very strong motive.
But they were Smith's finger-prints; and if he were not Smith, what
strong motive could he have had for taking them?"

"Admirably argued," Thorndyke commented. "But perhaps we had better
postpone the consideration of that point until we have actually
ascertained that the papers were really taken from the body. The point is
of importance in more than one respect. As you, very justly remark, the
taking away of these papers converts what might have been accepted as a
misadventure into an undeniable murder. And the man who took them--if he
did take them--could not have failed to realize this. You are certainly
right as to the strength of the motive. The question that remains to be
solved is, What might have been the nature of that motive? But I think we
shall have to adjourn this discussion."

As he spoke, I became aware of footsteps ascending the stairs, and
growing rapidly more audible. Their cessation coincided with a knock at
the door, which I instantly recognized as Miller's. I sprang up and threw
the door open, whereupon the Superintendent entered and fixed a
mock-reproachful eye on the uncleared breakfast-table.

"Well, gentlemen," he said, by way of greeting, "I thought I would just
drop in and give you the news in case you were starting early. You
needn't. The post-mortem is fixed for two-thirty, and there is nothing
else for you to do."

"Thank you, Miller," said Thorndyke. "It was good of you to come round.
But, as a matter of fact, we are not going--at least, I am not, and I
don't think Jervis is."

The Superintendent's jaw dropped. "I am sorry to hear that," said he in a
tone of very real disappointment. "I was rather banking on your getting
us some thing definite to go on. We haven't got much in the way of
positive evidence."

"That," Thorndyke answered, "is why we are not going. We have got some
positive evidence; and we think--and so will you--that we had better
keep it to ourselves, at least for the present."

The Superintendent cast an astonished glance at my colleague.

"You have got some positive evidence!" he exclaimed. "Why; how the
deuce--but there, that doesn't matter. What have you discovered?"

Thorndyke opened a drawer and produced from it a pack of mounted
photographs and the two cards bearing Badger's finger-prints, which he
laid on the table.

"You may remember, Miller," he said, "pointing out to me in the tunnel
that someone had thrown away a half-smoked cigar."

"I remember," the Superintendent replied. "An uncommon good weed it
looked, too. I had half a mind to pick it up and finish it--in a holder,
of course."

"It's just as well that you did not," Thorndyke chuckled. "However, I
picked it up. I thought there might possibly be some finger-prints on it.
And there were. Some of them were Badger's. But there were some others as
well."

"How were you able to spot Badger's finger-prints?" Miller demanded in a
tone of astonishment.

"I took the records from the body," Thorndyke replied, "on the chance that
we might want them."

Miller stared at my colleague in silent amazement.

"You are a most extraordinary man, Doctor," he exclaimed, at length. "You
seem to have the gift of second sight. What on earth could have made
you--but there, it's no use asking you. Are these poor Badger's prints?"

"Yes," Thorndyke answered, "and these are the photographs of the cigar
with the prints developed on it."

Miller pored eagerly over the photographs and compared them with the
prints on the cards.

"Yes," said he, after a careful inspection, "they are clear enough. There
is poor old Badger's thumb as plain as a pikestaff. And here is one--looks
like a thumb, too--that certainly is not Badger's. Now we are
going to see whose it is."

He spoke in a tone of triumph, and as he spoke, he whisked out of his
pocket, with something of a flourish, a large leather wallet. From this
he extracted a blue document and spread it out on the table. On it, among
other matter, were four sets of finger-prints--the "tips" of the two
hands, both sets complete, and the two sets of "rolled impressions," of
which those of the right hand consisted only of two perfect impressions
and a smear. Miller confined his attention principally to the tips,
glancing backward and forward from them to the photographs, which were
spread out on the table. And, watching him, I was sensible of a gradual
change in his demeanour. The triumphant air slowly faded away, giving
place, first to doubt and bewilderment, and finally to quite definite
disappointment.

"Nothing doing," he reported, handing the paper to Thorndyke. "They are
not Smith's finger-prints. Pity. I'd hoped they would have been. If they
had been, they would have fixed the murder on him beyond any doubt. Now
we shall have to grub about for some other kind of evidence. At present,
we've got nothing but the evidence of the station-master at Strood."

Thorndyke looked at him with slightly raised eyebrows.

"You seem," said he, "to be overlooking the importance of those other
finger-prints. If they are not Smith's, they are somebody's; and the
person who made them is the person who gave Badger that cigar."

"No doubt," Miller agreed. "But what about it? Does it matter who gave
him the cigar?"

"As it happens," Thorndyke replied, "it matters a great deal. We have
analysed that cigar and we found that it contained a very large dose of a
deadly volatile poison."

Miller was thunderstruck. For some moments he stood, silently gazing at
Thorndyke, literally open-mouthed. At length, he exclaimed in a low,
almost awe-stricken tone:

"Good God, Doctor. This is new evidence with a vengeance! Now we can
understand how poor old Badger was got out on to the line. But, how in
the name of fortune came you to analyse the cigar?"

"There was just the bare possibility," Thorndyke replied. "We thought we
might as well make the trial."

Miller shook his head. "It's second sight, Doctor. There's, no other name
for it. It looks as if you had spotted the poison in the cigar as it lay
on the ground in the tunnel. You are a most astonishing man. But the
question is, how the deuce he got hold of that cigar."

"Who?" demanded Thorndyke. "You don't, surely, mean Smith?"

"Certainly I do," Miller replied, doggedly. "Who else?"

"But," Thorndyke protested with a shade of impatience, "you have just
ascertained, beyond any reasonable doubt, that the cigar was given to
Badger by some other person."

But the Superintendent was not to be moved from the conviction that
apparently had possession of his mind. "Those other prints," he insisted,
"must be the prints of the man from whom Smith got the cigar. We shall
have to find out who he is, of course. But it is the murderer we want.
And the murderer is Frederick Smith, or whatever his real name is."

Thorndyke's sense of humour apparently got the better of his vexation,
for he remarked with a low chuckle:

 "It seems odd for me to pose as the champion of finger-print evidence.
But, really, Miller, you are flying in the face of all the visible facts
and probabilities. There is absolutely nothing to connect the man Smith
with that cigar."

"He may have worn gloves," suggested Miller.

"He may have worn a cocked hat," retorted Thorndyke. "But there is no
reason to believe that he did. Why do you cling to the unfortunate Smith
in this tenacious fashion?"

"Why," rejoined Miller, "look at the description on his paper and then
recall what the station-master at Strood said."

Thorndyke took up the paper and read aloud:

"'Height, 67 inches; weight, 158 pounds; rather thick-set, muscular
build. Hair, darkish red; eyes, reddish brown; complexion, fresh; nose,
straight, medium size, rather thick and distinctly red.' Yes, that seems
to agree with the station-master's description. I see that he gives no
address, but describes himself as a plumber and gas-fitter."

"Probably that is right," said Miller. "A considerable proportion of the
men who take to burglary started life as plumbers and gas-fitters. Their
professional training gives them an advantage."

"It must," I remarked a little bitterly, recalling the ravages of a
gas-fitter on my own premises. "There seems to be a natural connection
between gas-fitting and house-breaking."

"At any rate," said Thorndyke, who was now inspecting the
photographs--one profile and one full face--"the description fits the
man's presumed avocation, without insisting on the gas-fitting. It is a
coarse, common face. Not very characteristic. He might be a burglar or
just simply a low-class working-man."

"Exactly," the Superintendent agreed. "It's the sort of mug that you can
see by the dozen in the yard at Brixton or in any local prison. Just a
common, low-grade man. But that hasn't much bearing on our little
problem."

"I don't think I quite agree with you there, Miller," said Thorndyke.
"The man's general type and make up seem to have a rather important
bearing. We are dealing with a crime that is distinctly subtle and
ingenious, and which seems to involve a good deal more knowledge than we
should expect an ordinary working-man to possess. The face fits the
assumed character of the man; but it does not fit the crime. Don't you
agree with me?"

"I'll not deny," the Superintendent conceded, grudgingly, "that there is
something in what you say. Probably, we shall find that there was some
man of a different class behind Smith."

"But why insist upon Smith at all? The poisoned cigar is the one solid
fact that we have and can prove. And, as you have admitted, we have not a
particle of evidence that connects him with it. On the contrary, the
evidence of the finger-prints clearly connects it with someone else. Why
not drop Smith, at least provisionally?"

Miller shook his head with an air of resolution that I recognised as
hopeless.

"Theory is all very well, Doctor," he replied, "and I realise the force
of what you have pointed out. But you remember the old story of the dog
and the shadow. The dog who let go the piece of meat that he had in order
to grab the other piece that he saw reflected in the water was a foolish
dog. I'm not going to follow his example. This man, Smith, was seen to
get into the carriage with Badger. He must have been in the carriage when
Badger was killed; and no one else was there. If he didn't murder Badger,
it's for him to explain how the thing happened. And I fancy he'll find
the explanation a bit difficult."

Thorndyke seemed, for a moment, inclined to pursue the argument. But then
he gave up the attempt to convince the Superintendent and changed the
subject.

"What was the charge against Smith?" he asked.

"He was charged with uttering counterfeit paper money," Miller replied.
"It was a silly affair, really. I can't think how the magistrate came to
commit him. It seems that he went into a pub in Maidstone for a drink and
tendered a ten-shilling note. The publican spotted it at once as a bad
one and he gave Smith in charge. At the police station he was searched
and two more notes were found on him. But they were both genuine and so
was the rest of the money that he had about him. His statement was that
the note had been given to him in change, and that he did not know that
it was bad; which was probably true. At any rate, I feel pretty sure that
the Grand Jury would have thrown out the bill. He was a mug to complicate
matters by bolting."

"So, as an actual fact, there is no evidence that he was a criminal at
all. He may have been a perfectly respectable working-man."

"That is so," Miller agreed rather reluctantly, "excepting that Badger
seemed to have been satisfied that he was the crook that he had been on
the look-out for."

"As he never saw the man," said Thorndyke, "that is not very conclusive.
Do you know how the escape was managed?"

"Only in a general way," replied Miller. "It doesn't particularly concern
me. I gather that it was one of those muddles that are apt to occur when
prisoners are wearing their own clothes. Got himself mixed up with a gang
of workmen. But he'd better have stayed where he was."

"Much better," Thorndyke agreed with some emphasis. "But, to return to
the case of the unknown man who prepared the poisoned cigar, I think you
will agree with me that we had better keep our own counsel about the
whole affair."

"I suppose so," answered Miller. "At any rate, I think you are right to
keep away from the inquest. The coroner might ask you to give evidence,
and then you'd have to tell all you know, and the story would be in every
blessed newspaper in the country. I take it you are prepared to swear to
the poison in that cigar?

"Certainly; and to produce the poison in evidence."

"And you are going to let me have a photograph of those finger-prints?"

"Of course. There is a set ready for you now, including two of Badger's.
And, as to those from the cigar, it is just possible that you may find
them to be those of some known person."

"It's possible," Miller admitted, "but I don't think it very likely."

"Nor do I," said Thorndyke, with a faint smile; by which I judged that he
realized, as I did, that Miller's suspicions, even in the matter of the
cigar, were still riveted on the elusive Smith.

"With regard to this paper of Smith's," said Thorndyke, as he handed
Miller the set of photographs that had been reserved for him; "I should
like to take a copy of it for reference. A photographic copy, I mean, of
the portraits and the finger-prints."

Miller looked a little unhappy. "It wouldn't be quite in order," he
objected. "An official document, you know, and a secret one at that. Is
it of any importance?"

"It is impossible to say, in advance," replied Thorndyke. "But I shall be
working at the case on your behalf and in collaboration with you. It
might be important, on some occasion, to be able to recognize a face or a
finger-print. Still, if it is not in order, I won't press the matter. The
chances are that the copy will never be needed."

But Miller had reconsidered the question. He was not going to put any
obstacles in Thorndyke's way.

"If you think a copy would be helpful," said he, "I'll take the
responsibility of letting you have one. But I can't let the document go
out of my possession. Can you take it now?"

"Yes," Thorndyke replied. "It will be only a matter of a minute or two,
to make one or two exposures."

Without more ado, he took the document and went off with it to the
laboratory. As he disappeared, the Superintendent commented admiringly on
the efficiency of our establishment.

"Yes," I replied, with some complacency (though the efficiency was none
of my producing), "the copying camera is a great asset. There it is,
always ready at a moment's notice to give us a perfect facsimile of any
thing that is set before it--an infallible copy that will be accepted in
any court of law, But you have quite as good an outfit at the Yard."

"Oh yes," Miller agreed, "our equipment and organization are good enough.
But, in a public department, you can't get the flexibility and
adaptability of a private establishment like yours, where you make your
own rules and use your own judgment as to obeying them. This can't be the
Doctor, already."

It was, however. Thorndyke had just made the exposures and left the
development to be done later. He now returned the document to the
Superintendent, who, having carefully bestowed it in his pocket with the
photographs, rose to take his departure.

"I hope, Doctor," he said, as he shook hands with Thorndyke, "that I
haven't seemed unappreciative of all that you have done. That discovery
of yours was a most remarkable exploit--a positive stroke of genius.
And it has given us the only piece of real evidence that we have.
Please don't think that I'm not grateful."

"Tut, tut," said Thorndyke, "there is no question of gratitude. We all
want to catch the villain who murdered our old friend. Are you going to
the inquest?"

"No," replied Miller. "I am not wanted there; and, now that you have
given me this new information, I feel, like you, that I had better keep
away, for fear of being compelled to let the cat out of the bag. You said
you were sending a shorthand reporter down to take notes for you."

"Yes," said Thorndyke; "Polton has made all the arrangements, and has
told our man to type the notes out in duplicate so that you can have a
copy."

"Thanks, Doctor," said Miller. "I think they may be useful, after all,
particularly the station-master's evidence concerning the man he saw at
Strood."

"Yes," agreed Thorndyke. "It will be a great point if he can recognize
the prison photograph--and an almost equally great one if he cannot."

I seemed to gather from the Superintendent's expression that he did not
view the latter contingency with any great enthusiasm. But he made no
rejoinder beyond again wishing us "Good morning," and at length took his
departure, escorted to the landing by Thorndyke.

Chapter VIII: A Review of the Evidence

WHEN Thorndyke re-entered the room, closing the oak door behind him, he
appeared to be in a thoughtful and slightly puzzled frame of mind. For a
minute or more, he stood before the fireplace filling his pipe in
silence and apparently reflecting profoundly. Suddenly he looked up at me
and asked:

"Well, Jervis; what do you think of it all?"

"As to Miller? I think that he has his nose glued to the trail of Mr.
Frederick Smith."

"Yes," said he. "The Smith idea almost amounts to an obsession; and that
is a very dangerous state of mind for a detective superintendent. It may
easily lead to a bad miscarriage of justice."

"Still," I said, "there is something to be said for Miller's point of
view. The man who got into the train at Strood did certainly agree, at
least superficially, with the official description of the man Smith."

"That is quite true," Thorndyke admitted. "The report of the evidence at
the inquest will show what sort of description the station-master is
prepared to swear to. But I don't feel at all happy as to Miller's
attitude. We shall have to watch events closely. For we are deeply
concerned in this investigation. And it will be just as well if we go
over the facts that are known to us and consider what our own attitude
must be."

He took up a pencil and a note-block, and, dropping into an easy chair,
lit his pipe and opened the discussion.

"I think, Jervis," he began, "we are justified in assuming that the man
who got into the carriage at Strood is the man who murdered Badger."

"I think so," I agreed. "That is, if we assume that it was really a case
of murder. Personally, I have no doubt on the subject."

"I am assuming that the document was really in Badger's pocket when he
started, and that it was not there when his body was examined by the
sergeant. The inquest notes will confirm or exclude those assumptions. At
present, our information is to the effect that they are true. And if they
are true, the document must have been taken from Badger's pocket; and
that fact furnishes prima facie evidence of murder. But if Badger was
murdered, the Strood man must be presumed to be the murderer, since no
other possibility presents itself. Hence, the question that we have to
settle, or at least to form a definite opinion on, is, Who was the Strood
man?

"Now, our information is to the effect that he had red or reddish hair
and a noticeably red nose. But the man Smith has dark-red hair and a
noticeably red nose. Then it is possible that the Strood man may have
been Smith. But mere coincidence in these two characteristics does not
afford positive evidence that he was. For two men resembling one another
in these respects might be otherwise very different."

"That is so," said I. "But you must admit that it is a rather remarkable
coincidence. And you have often pointed out, with great justice, that
coincidences call for very careful consideration."

"Precisely," said he. "And that is what I am going to insist on now. We
have to note the coincidence and ask ourselves what its significance may
be. It is, as you say, a quite remarkable coincidence. Neither of these
peculiarities is at all common. If you were to examine any considerable
collection of men, such, for example, as a battalion of infantry, how
many men with dark-red hair would you find in it? Not more than one or
two. Perhaps not one. But, of the one or two, or say half a dozen, that
you found, bow many would have noticeably red noses? Most probably none.
Improbabilities become rapidly cumulative as you multiply the
characteristics that are postulated us appearing coincidently.

"The position, then, in regard to the Strood man is this: In two salient
personal characteristics, he resembled the man Smith. That resemblance
can be accounted for by three hypotheses, one of which must be true:

"1. That the Strood man was Smith.

"2. That he was another man who happened to resemble Smith.

"3. That he was another man who had been purposely made up or disguised
so as to resemble Smith.

"Those are the only possibilities and, as I said, one of them must be
true. Let us take them in order and consider their respective
probabilities. We begin with the first hypothesis, that the Strood man
was Smith. Now, in order to judge of the probability of this, we have to
consider what we know of the personality of Smith and of the Strood man
respectively and to decide whether what we know of the one is compatible
with what we know of the other.

"Now, what do we know of Smith? First, we have the fact that he described
himself as a plumber and gas-fitter. As that description seems to have
been accepted by the prison officials, we may assume that it fitted his
appearance and manner; and we see that his face is of the type
characteristic of the lower class of working-man. We know, further, that
he had just escaped from prison, and that he was known and could have
been recognized by several persons at the prison, including Chief Officer
Cummings. It is probable that when he escaped, his pockets were empty and
he may have been hatless.

"Now as to the Strood man. It is almost certain that he had a first-class
ticket; that he travelled from Maidstone in Badger's train, and, if so,
he must have been on the platform at Maidstone at the same time as Badger
and Cummings. He carried in his pocket a cigar which had been treated
with a poison which is practically unprocurable commercially and which he
must almost certainly have prepared himself. Now, Jervis, does it seem to
you possible that those two descriptions could apply to one and the same
person?"

"No," I replied, "it certainly does not, though you omitted to mention
that Smith is probably a burglar."

"That is not known to us, though I admit that it is not improbable. But
it really has no bearing. Even if we knew that he was a burglar, all the
obvious discrepancies would remain. I submit that the hypothesis that the
Strood man was the escaped prisoner, Smith, must be rejected as
untenable.

"We pass on, then, to the next possibility, that the Strood man was not
Smith, but was a man who happened to resemble Smith these two physical
characteristics. In order to state the probabilities, it is necessary to
note that the Strood man was apparently in this train with the
premeditated purpose of murdering a police officer, and that a few hours
previously a man with dark-red hair and a noticeably red nose had escaped
from a Maidstone prison and was still at large. Bearing in mind the
rarity of this combination of physical characters, what do you think of
the probability of the coincidence?"

"Well," I replied, "obviously, the chances against are a good many
thousands to one. But that is not quite the same thing as certainty."

"Very true, Jervis," he agreed, "and very necessary to remember. It is by
no means safe to apply the laws of chance to individual cases. A prize of
£30,000 in a lottery or sweepstake necessarily implies sixty thousand
ten-shilling tickets, of which all but one must be blanks; so that the
chances against any ticket holder are fifty-nine thousand nine hundred
and ninety-nine to one. Nevertheless, in spite of that enormous adverse
chance, someone does win the prize. You are quite right. Long odds
against do not exclude a possibility. But, still, we have to bear the
odds in mind; and, if we do, we shall be very indisposed to accept this
coincidence.

"We are left with the third hypothesis: that the Strood man was an
unknown man, deliberately disguised or made up to resemble the escaped
prisoner, Smith. This suggestion, though it has certain positive elements
of probability, has also certain weighty objections, as I have no doubt
you have noticed."

"I see one objection," said I, "that seems to exclude the suggestion
altogether. If the Strood man had made up to resemble Smith, he must have
had the means with him, provided in advance. He couldn't have gone about,
habitually, with a red wig and a bottle of rouge in his pocket. But the
escape of Smith was a contingency that couldn't have been foreseen. If we
accept the idea of the make-up, we have to suppose that, after hearing of
Smith's escape, this man was able to provide himself with the wig and the
rouge. That seems to be quite incredible."

Thorndyke nodded, approvingly.

"Very true," said he. "My learned friend has made a palpable hit. It is a
very serious objection, and, as you say, it appears, at the first glance,
to be insuperable--to render the hypothesis quite untenable. But if you
consider the circumstances more thoroughly, you will see that it does
not. The probability is that we are dealing with one of those
combinations of chance and design that are always so puzzling and so
misleading. Let us exercise our imaginations a little further and make
one or two more hypotheses. Let us suppose I that this man had already
decided to avail himself of Smith's conspicuous peculiarities and to
personate him to that extent--presumably for some unlawful purpose. He
would then have had the wig and the rouge in readiness. Suppose that he
is staying in Maidstone, perhaps keeping a watch on Smith. Smith,
however, is in custody, with the certain result that his personal
peculiarities will be noticed in detail and recorded.

"This will make him much better worth personating. If the stranger is
keeping a watch on Smith, he will know about the prosecution, and he will
know that there is a good chance of an acquittal. Suppose, now, at this
point, two unforeseen events happen: Smith makes his escape, and then
Badger turns up in Maidstone. The stranger has, as the murder pretty
clearly proves, some strong reason for getting rid of Badger. But here is
a set of unforeseen circumstances that creates a first-class opportunity.
The apparent impossibility of the disguise is an additional favourable
factor."

I was impressed by my colleague's ingenuity and said so, perhaps with
some faint suggestion of irony in my tone.

"Of course," I hastened to add, "all that you suggest is quite possible.
The trouble is, that it is quite imaginary. There is not a particle of
direct evidence to suggest that it is true--that what you postulate as
having possibly happened, really did happen."

"No," Thorndyke admitted, "there is not. It is hypothesis, pure and
simple. So far, I do not contest your objection. But I remind you of our
position. We have three hypotheses which represent all the imaginable
possibilities. One of the three must be the true one. But we have already
excluded two as being quite untenable on the grounds of extreme
improbability. The third is admittedly difficult to accept; but it is far
less improbable than either of the other two. And you notice that, if we
make the assumptions that I suggest, what follows presents a high degree
of probability. I mean that a man, setting out to commit a murder, under
circumstances in which he must be seen in the company of his prospective
victim, would be taking a very ordinary precaution if he should so alter
his appearance that a description of the murderer would not be a
description of himself. And if he had the opportunity to make up so as to
resemble some other person, and that other person an escaped prisoner, it
would be very much to his advantage to take it. How great the advantage
would be, we can see for ourselves by the attitude of our old friend, the
Superintendent."

"Yes, by Jove!" said I. "The deception, if it is one, has operated most
effectively on Miller. And, if your suggestion is correct, it will
explain another rather incomprehensible thing--I mean the taking from
the body of the prison record. That naturally suggested that the murderer
was the man whose description was on the stolen document. In fact, my
impression is that it is the document as much as the personal resemblance
that is sticking in Miller's gullet."

"I think you are right," said Thorndyke. "At any rate, the combined
effect of the two facts--the theft of the document and the personal
characteristics--is undoubtedly responsible for his state of mind. But,
to return to our discussion, I think that, out of the three hypotheses
from which we have to choose, we are forced to adopt the third, at least
provisionally: that the man who murdered Badger is not Smith, but is some
unknown man who had deliberately made up to the end that he might be
mistaken for Smith."

"Yes," I agreed. "I suppose we are, since the other two suppositions
cannot be reasonably entertained. But I could wish that it were a little
more easy to accept. It involves an uncomfortable amount of unproved
assumptions."

"So it does," he admitted. "But there it is. All three hypotheses seem to
be full of improbabilities. But, as one of them must be the true one,
since there are no others, we have no choice but to adopt the one that
presents the smallest number of improbabilities and the greatest number
of probabilities. Still, as I have said, our acceptance is only
provisional. We may have to revise our opinions when we have the evidence
of the witnesses at the inquest before us."

In the event, however, we did not. On the contrary, when, late in
the evening, our very expert stenographer delivered the copy of his
notes--typed in duplicate--the report of the witnesses' evidence tended
rather to confirm Thorndyke's conclusions. There was nothing very
definite, it is true; but the few additional facts all pointed in the
same direction.

There was, for instance, the station-master's evidence. It seemed that,
in the interval, he had thought matters over, and his statements were now
more decided. He was able, moreover, to amplify his description of the
suspected stranger. The latter he described as a well-dressed man of
about middle age, carrying a good-sized hand-bag of brown leather, but no
stick or umbrella, and wearing a soft felt hat. The man had a rather
conspicuously red nose. He had noticed that particularly--"thought the
gentleman looked as if he were in the habit of taking a drop." And he was
quite clear about the colour of the man's hair. He noticed it as the
stranger was getting into the carriage and the sun shone on the back of
his head. It was distinctly red; dark red or auburn--not bright red, and
certainly not sandy. Probably, in the sunlight, it may have looked rather
redder than it really was. But it was definitely red hair.

"Do you think that you would recognise the man if you were to see him?"
the coroner asked.

"I don't much think I should," was the cautious reply. "At any rate, I
shouldn't be able to swear to him."

Here the coroner apparently produced the prison form with the two
photographs and handed it to the witness.

"I want you to look at those two portraits," said he, "and tell us
whether you recognize them."

The witness examined them and replied that he did not recognize them.

"Does the face that is shown in those photographs seem to you to resemble
the face of the red-haired stranger?"

"I don't see any resemblance," the witness replied.

"Do you mean," the coroner pursued, "that you simply don't recognize the
face, or that it seems to you to be a different face?"

"I should say that it is a different face. The man I saw looked more like
a gentleman."

"You are definitely of opinion that these photographs are not portraits
of the man that you saw. Is that so?"

"Well, sir, I shouldn't like to be positive, but these photos don't look
to me like the man I saw on the platform."

That was all that was to be got out of the station-master; and, so far,
it tended to support Thorndyke's view; as also did the evidence of the
ticket collector at Dartford, who was the next witness. He, like the
station-master, seemed to have turned the matter over in his mind, though
he was not able to give much more information. He did, however, remember
collecting a first-class ticket, and recalled noticing that it was from
Maidstone to London.

"That," said the coroner, "is a point of some significance. This
passenger started from Maidstone with the intention of going to London,
but at Dartford--the next station after Greenhithe--he suddenly changed
his mind. It is a fact to be noted. Do you remember what this man was
like?"

"I can't say that I remember him very clearly," the witness answered. "You
see, sir, I was looking at the tickets. But I do remember that he was
carrying a largish brown hand-bag."

"Do you remember anything peculiar in his appearance? You have heard the
last witness's description of him. Can you say whether this passenger
agreed with that description?"

"I wouldn't like to say positively whether he did or whether he didn't. I
can only say that I didn't notice that he had a particularly red nose,
and I didn't notice the colour of his hair. As far as I remember him, he
seemed an ordinary, gentlemanly sort of man; the sort of man that you
would expect to hand in a first-class ticket."

So much for the ticket collector. His evidence did not carry us very far.
Nevertheless, such as it was, its tendency was to support Thorndyke's
suggestion. There could be little doubt that the man who had given up the
first-class ticket was the Strood man; and the fact--though it was only
a negative fact and of little weight at that--that the special
peculiarities of nose and hair had not been observed, seemed to lend a
faint support to Thorndyke's further suggestion that, as soon as the
murder had been committed, those special peculiarities would be
eliminated.

There was little else in the evidence that was of interest to us. The
engine-driver's evidence had practically no bearing; for poor Badger's
body was unquestionably on the line, and the details as to how long it
could have been there did not affect our enquiry. As to the body itself,
the fact that no injuries could be discovered other than those inflicted
by the train now caused us no surprise, though, to the coroner, it was
naturally rather puzzling. Indeed, the problem that had so exercised the
mind of Superintendent Miller was the problem that the coroner discussed
at the greatest length and with complete failure to find any plausible
solution. I read his very just and reasonable comments with considerable
sympathy, not without a twinge of compunction as I reflected on the way
in which we had withheld from him the one conclusive and material fact.

"The greatest mystery in this strange case," he observed, "is the absence
of any traces of injury. Here was a powerful, highly trained
police-officer, flung out on the line by a man whom he had apparently
intended to arrest. He had not been shot, or stabbed, or stunned by a
blow on the head, or in any way disabled. He had been simply thrown out.
It seemed incredible; but there were the facts. But for the known
presence in that carriage of another person, and that person a suspected
criminal, the condition of the body would have pointed to an accident of
a quite ordinary kind. But the presence of that other man, and especially
the fact--which has been quite conclusively proved by the evidence of
Chief Officer Cummings--that a certain document was taken from the
pocket of the deceased, puts accident entirely out of the question.

"But it adds enormously to the difficulty of understanding how this crime
could have been committed. For, obviously, deceased would not have
allowed this document to be taken from him without very energetic
resistance. The great mystery is how any ordinary man could have taken
this document forcibly from this powerful, capable officer and then
opened the door and thrown him out on to the line. I must confess that I
cannot understand it at all.

"However, our failure to unravel the mystery of the actual method
employed by the murderer does not leave us in any doubt as to how
deceased met his death; which is the subject of our inquiry. The presence
of that unknown man, his immediate disappearance at the very first
opportunity, and the theft of that document, are facts that are too
significant to allow of any but one interpretation.

"The next question presents much more difficulty--the question as to the
identity of that man. If we think that we can give him a name, it is our
duty to do so. But it is not the concern of a coroner's inquest to prove
the guilt of any particular person. That is the office of a court of
criminal jurisdiction. Unlike such a court, we have the choice of
returning an open verdict--open, that is to say, as regards the identity
of the criminal. And, if we have any doubt as to his identity, that is
our proper course. Now, you have heard the evidence relating to the
identity of the man who shared the compartment with deceased. You cannot
have failed to notice the conflicting nature of that evidence, nor can
you have failed to be impressed by the unlikeliness of an escaped
prisoner showing himself openly on the platform of Maidstone Station.
Still, if you are satisfied with such proof of his identity as has been
given, your finding must be to that effect; but, if you have any doubts,
you will be wiser to leave the investigation of that point to the
police."

This eminently judicious advice the jury accepted, eventually returning a
verdict of "Murder by some person unknown."

"Well," said Thorndyke, as I handed him back the copy of the notes, "has
my learned friend any comments to make?"

"Only," I replied, "that the evidence, such as it is, seems rather to
justify your choice of the third hypothesis."

"Yes," he agreed. "There is not much that is new. But there is one point
that I dare say you noticed. The Strood man was carrying a fair-sized
hand-bag. That supports the 'make-up' theory to this extent: that a
hand-bag would be almost a necessity, seeing that a wig is a rather bulky
article, and one that must not be too roughly treated, as it would be by
being stuffed in the pocket. Then, the ticket collector's evidence,
little as it was worth, leaned to our side. He did not notice that the
passenger had either a red nose or red hair; which might mean either that
those characters were not there to notice, or simply that he took no note
of the man's appearance. There isn't much in it either way.

"But there is one other point that emerges--a slightly speculative
point, but very important in its bearing if we accept it, though rather
obvious. If we assume that this man was made up to pass, at least in a
printed description, as Frederick Smith, that points to some kind of
connection between him and Smith. He must, as you very justly observed,
have made his preparations in advance. That is to say, he had decided, at
least a few days previously, and probably more, to adopt Smith's
peculiarities to cover some unlawful proceedings of his own. Now, it is
highly improbable that he would have selected a complete stranger as the
model for his disguise; and, as a stranger, he could not have known that
Smith was under suspicion of being a member of the habitual criminal
class. But it was this suspicion that gave the disguise its special
value. The evident probability is that he had some rather intimate
knowledge of Smith."

"That does seem to be so," I agreed. "But, if it is true, another
interesting probability emerges. If he knew something about Smith, then
there must have been something to know. That is to say, our friend
Badger's suspicions of Smith were not without some real foundation. And,
again, the connection that you suggest might account for the theft of the
finger-print document. It might not suit the murderer to have the
finger-prints of his under-study--or over-study--at Scotland Yard."

"I think you are right," said Thorndyke, "as to the probable facts,
though I am doubtful about your view of the motive. The theft of the
document threw the suspicion at once on Smith, since they were his
finger-prints and description. That would appear to have been the object of
the theft as it was the object of the disguise."

"If it was," said I, "it was a diabolical scheme."

"Very true," Thorndyke agreed; "but murderers are not a peculiarly
scrupulous class, and this specimen seems to have been even below the
average in that respect. But, to revert to your suggestion that Badger's
suspicions probably had some foundation, you notice that the fact of
Smith's having taken the chance to escape tends to confirm your view.
Taking his position at its face value, that escape was really not worth
while. He was apparently innocent of the offence with which he was
charged, and pretty secure of an acquittal. His escape merely complicated
the position. But, if he was a regular criminal who ran the risk of being
recognized by some visiting detective, it might well have appeared to him
to be worth while to try the chance of getting away in the hope that he
might keep away."

At this point our discussion was interrupted by the sound of a visitor
approaching our landing. A moment later the identity of that visitor was
disclosed by a characteristic knock at the door.

"I happened to be passing this way," said Miller, as I let him in, "so I
thought I would just drop in and see if your shorthand notes were
available. I have seen the newspaper reports of the inquest."

"Then you will have seen that the station-master did not recognise the
prison photographs," said Thorndyke, as he handed the Superintendent his
copy of the typed notes.

"Yes," growled Miller. "That's rather disappointing. But you can't expect
an ordinary, unskilled person to spot a face after just one casual
glance. Of course, Badger spotted him. But he was a genius in that way.
It was a special gift."

"A rather dangerous one, as it turned out," I remarked.

"It was, under the circumstances," said Miller. "But what made it
dangerous was poor Badger's secretiveness. He liked to hold the
monopoly--to feel he was the only detective officer who could identify
some man who was wanted but unknown. Even in cases that he was not
really concerned in, he would keep a criminal's personal description
up his sleeve, as it were. I remember, for instance, in that Hornby
case--the Red Thumb Mark case, as they called it--how close he was."

"But he wasn't on that case, was he?" I asked.

"No. That was my case, and a pretty mess I made of it. But Badger was in
court on another case, and it seems that, for some reason, he kept an eye
on that man, Hornby--the one I had a warrant for, you know--while the
experts were giving their evidence. Well, as you remember, Hornby slipped
off, and I went after him and missed him; and when it came to making out
a description of him, I had to apply to you for details. I doubt if I
could have spotted him if I had met him in the street. But long
afterwards, Badger told me that he had a perfectly clear mental picture
of the man's face, and that he was certain that he could spot him at a
glance if ever they should meet. And he was like that with quite a number
of crooks of the more uncommon kind. He could recognize them when no one
else could. It was a valuable gift--to him. Not so valuable to us. And,
as you say, it has its dangers. If a really vicious crook got to know
what the position was, he might show his teeth, as this man did in the
train. Badger would have been wiser in several respects to have shared
his information with his brother officers."

"Yes," said Thorndyke, "it is not very safe to be the sole repository of
a secret that threatens another man's life or liberty. I have had reason
to realize that more than once. By the way, have you had an opportunity
of getting that strange finger-print examined--the one, I mean, that we
found on the cigar?"

"Yes; and drawn another blank. I took it to the Finger-print Bureau, but
they haven't got it in any of the files. So your poison-monger is a
'person unknown' at present. What you might expect. Probably sits in the
background and supplies his infernal wares to crooks of a less subtle
kind. However, your photo has been filed in the 'Scene of the Crime'
series of single finger-prints. So we shall be able to place him, if we
ever get him in custody. That will be quite a nice little surprise for
him. But I mustn't stay here gossiping. I've got a lot to do before I
knock off for the day. Among other things, I must go carefully through
these notes that you have been so kind as to let me have, though I am
afraid there is nothing very helpful in them."

As he retired down the stairs, Thorndyke stood looking after him with a
faint smile.

"You observe," he remarked, "that our friend is still under the influence
of the Smith obsession. I have never known Miller to be like this before.
We have given him a piece of evidence of cardinal importance, and he
treats it as something merely incidental. And that thumb-print, which is,
almost beyond any doubt, the thumb-print of Badger's murderer, he files
away as a thing that may possibly be of some slight interest on some
unvisualized future occasion. It is an astonishing state of mind for an
officer of his experience and real ability. We shall have to watch this
case for his sake as well as our own. We must try to prevent him from
making a false move; and we have got to find poor Badger's murderer, if
any efforts of ours are equal to a task that looks so unpromising."

"It certainly looks unpromising enough," said I. "The man whom we have to
find is a mere phantom, a disembodied finger-print, so to speak. We don't
know his name; we don't even know what he is like, since the only
description we have of him is the description of a disguise, not of a
man. We can only assume that he has neither red hair nor a red nose. But
that description applies to a good many other people."

Thorndyke smiled at my pessimism, but was fain to agree that I had not
overstated the case. "Still," he continued, hopefully, "things might have
been worse. After all, a finger-print is a tangible asset. We can
identify the man if we are ever able to lay hands on him."

"No doubt," I agreed, less hopefully, "but the laying hands on him is the
whole problem. And it seems to be a problem with no solution."

"Well," he rejoined, "what we have done before we can do again. We have
had to deal with unknown quantities, and we have resolved them into known
quantities. It is not the first time that we have been confronted with
the uncompleted equation, 'x=?'."

"No, indeed," said I. "You used that very formula, I remember, in the
case of that man whom Miller was speaking of just now, Walter Hornby, and
on the very occasion he referred to. I recall the incident very vividly.
Don't you remember? When you passed me that slip of paper with the
scribbled note on it, 'x=Walter Hornby'?"

"I remember it very well," he replied. "And I have quite good hopes that
we shall complete the equation in this case, too, if we are patient and
watchful."

"Knowing you as I do," said I, "and remembering those other cases, I,
also, am not without hope. But I cannot imagine how you are going to get
a start. At present there is absolutely nothing to go on."

"We shall have to wait for some new facts," he rejoined, "and remember
that the force of evidence is cumulative. At present, as you say, the
whole case is in the air. But I have a strong feeling that we have not
heard the last of Mr. Frederick Smith. Now that his finger-prints and
description are extant, I think we may look for him to make another
appearance; and when he does, I suspect that we shall make a step
forward."

At the moment, I did not quite perceive the bearing or significance of
this statement; but, later, as had so often happened, I looked back on
this conversation and marvelled at my obtuseness.

Chapter IX: Thorndyke discourses on Finger-prints

THORNDYKE'S prediction was verified with a promptitude that neither of us
expected, for little more than fortnight had elapsed after our
conversation on the subject when the elusive figure of Mr. Frederick
Smith once more flitted across our field of vision. It was but a fleeting
and spectral appearance and disappearance--at least that was what we
gathered from the news paper. Indeed, we might have missed it altogether
had not Thorndyke's eye been attracted by the heading of the small and
inconspicuous paragraph: "ESCAPED PRISONER BREAKS INTO HOUSE."

"What, already!" he exclaimed; and as I looked up enquiringly he
proceeded to read out the brief account.

"'A daring robbery--or rather, attempted robbery--was committed
yesterday in broad daylight by a man who escaped a short time ago from
Maidstone Gaol. The scene of the attempt was a detached house in Sudbury
Park, N.W., which had been left unoccupied owing to the owners having
gone out for a day's motoring. Apparently the man was disturbed, for he
was seen making off hurriedly; but, though he was immediately pursued, he
disappeared and succeeded in making good his escape. However, he was seen
distinctly by at least two persons, and the description that they were
able to give to the police enabled the latter to identify him as the
escaped prisoner.'"

As he laid down the paper, Thorndyke looked at me with a faint smile.

"Well," he said, "what does that announcement convey to my learned
friend?"

"Not very much," I replied, "excepting a red head with a red nose affixed
to it. Obviously, the observers noted his trade-marks."

"Yes," he agreed. "And you observe that he elected to do this job in
broad daylight. He must be a conceited fellow. He seems to be unduly
proud of that nose and those auburn locks."

"Still," said I, "he had to enter the house when it was unoccupied, and
that happened to be in the day time, when the owners were out in their
car. Only, what strikes me is that the identification is not very
satisfactory, even allowing for the rarity of red hair in combination
with a red nose."

"Wait until you have heard Miller's account of the affair," he rejoined.
"I am prepared to hear that the identification was more complete than one
would gather from the paper. But we shall see."

We did see, a few days later, and, as usual, Thorndyke was right.
When, about eight o'clock at night, the Superintendent's well-known
knock sounded on the door, I rose expectantly to admit him; and, as
he strode into the room, something of satisfaction and complacency in
his manner suggested that he was the bearer of news that he was going
to enjoy imparting to us. Accordingly, I hastened to dispose of the
preliminaries--the whisky decanter, the siphon, and the inevitable box
of cigars--and when he was comfortably settled in the arm-chair, I gave
him the necessary "lead off."

"I am sorry to see that our friend, Freddy, has been naughty again."

He looked at me for a moment enquiringly, and then, as the vulgar phrase
has it, he "rumbled" me.

"Ah," said he, "you mean Frederick Smith of Maidstone. Saw the paragraph
in the evening paper, I suppose?"

"Yes. And we thought it uncommonly smart of your people to spot Mr.
Frederick Smith from the casual description of one or two persons who
caught a glimpse of him as he was making off."

Miller evidently felt himself to be in a position to ignore the hardly
veiled sarcasm, for, without noticing it, he replied:

"Ah, but it was a good deal more than that. Of course, when we heard the
description, we pricked up our ears. But we soon got some clues that made
us independent of the description. I've come in to tell you about it,
since you are really interested parties.

"I dare say you know this place, Sudbury Park. It is one of the queer old
London survivals--a row of detached houses, each standing in its own
grounds, with gardens backing on the Regent's Canal, and little lanes
here and there running up from the tow-path between the gardens to the
road on which the houses front. The grounds that surround them are mostly
pretty thickly wooded--sort of shrubberies--and they are enclosed by
fairly high walls, the tops of which are guarded in the old-fashioned way
by broken bottles and bits of glass set in cement.

"Now, it seems that our friend first drew attention to himself by
breaking one of the back windows and making a good deal of noise in doing
it. Then a couple of women, attracted by the noise, saw him trying to get
in at the window. They were at a back window of one of the houses on the
opposite side of the Canal. Naturally as soon as they saw what he was up
to, they raised a philalloo and ran down to the garden to watch him over
the wall. Their squawking brought a party of bargees along the tow-path,
and when the bargees had been 'put wise' about the house-breaker, off
they started, full gallop, towards a bridge that crosses the Canal two or
three hundred yards farther down.

"Meanwhile, our honest tradesman, hearing the hullabaloo, concluded that
the game was up, and came tumbling out through the window like a
harlequin, and was in such a hurry that he left his cap inside, and so
displayed his beautiful auburn hair to the best advantage. He had been
working in his shirt-sleeves, and, when he started to run, the reason was
obvious. He wanted his coat--which he carried on his arm--to lay on the
broken bottles on the top of the wall so that he could climb over without
tearing his trousers. And that is what he did. He laid the coat over the
party wall, and over he went into the next shrubbery. But, unfortunately
for him, as he dropped down on the farther side, the coat slipped off the
wall and dropped down into the garden that he had left. For a moment he
seemed disposed to go back for it. But by that time the bargees were
running across the bridge, bellowing like bulls of Bashan. So our friend
thought better of it, and bolted away into the shrubbery and was lost to
sight."

"Was he not seen by the occupants of that house?" Thorndyke asked.

"No--because there weren't any. It was an empty house. So all he had to
do was to slip up by the side way and go out by the tradesmen's entrance.
But it is odd that no one saw him in the road. You would think that a
red-headed man in his shirt-sleeves, legging it up a quiet road, would
attract some attention. But, apparently, no one saw him, so he got clear
away--for the present, at any rate.

"But we shall have him, sooner or later. Sooner, I fancy. For, I tell you
we mean to have him. And the traces that he left will make him a valuable
catch when we do get him. A capture will mean a conviction to a dead
certainty."

"That is putting it rather strongly," I remarked.

"Not too strongly," he replied, confidently. "Let me tell you what we
found. First there was the broken glass. We went through that carefully,
and on one of the pieces we found a most beautiful impression of Mr
Frederick Smith's right thumb. And thereby hangs a tale which I will tell
you presently. Then there was the coat. That looked hopeful. But what it
actually yielded was beyond our wildest hopes. Most of the contents of
the pockets were of no particular interest. But there was one treasure of
inestimable value--an empty envelope that had apparently been used to
carry some hard object, for there were some sharp, rubbed marks on it.
But they did not interest us. What set us all agog was the address--Mr.
Charles Dobey, 103 Barnard's Buildings, Southwark.

"I need not tell you that we went off like record-breaking lamplighters
to Barnard's Buildings. There, at the office, we learned that the tenant
of number 103, Mr. Dobey, was a gentleman with a red head and a nose to
match. So up we went to number 103. We had provided ourselves with a
search warrant, and the officer who went with me took with him a little
battery of skeleton keys. So we soon had the door open."

"What kind of key opened it?" asked Thorndyke.

"Oh, just a common pipe key with the bit filed away. The sort you
generally use, I expect," Miller added with a grin. "It was only a common
builder's latch. Well, when we got inside we had a look round, but at
first there didn't seem to be much to see. It was just common, squalid
sort of room with hardly any furniture in it. Looked as if it was not
regularly lived in; which agreed with what the man in the office said--that
he didn't very often see Mr. Dobey. However, presently we
discovered, hidden under the bed, a good-sized oak box. It had a quite
good lever lock which gave my colleague no end of trouble to open. But it
was worth the trouble. When, at last, he got it open, we saw that we had
struck it rich. It was a regular treasury of evidence.

"First there was a full outfit of good-class burglar's tools, and there
were one or two little packets of jewellery which we have since been able
to identify from our lists as part of the swag from a burglary at a
jeweller's shop. Well, that was all to the good. But the real prize was
at the bottom of the box. I wonder if you can guess what it was?"

He looked a little anxiously at Thorndyke, and did not seem particularly
gratified when the latter suggested:

"It did not chance to be a document?"

"That is just what it did chance to be," Miller admitted, adding:
"You are a devil at guessing, Doctor. But you are quite right. It was
the paper that was taken from poor Badger's pocket in that infernal
tunnel at Greenhithe. So now we have got conclusive evidence as
to who murdered Badger. Of course, we shall have to look into the
meaning of that cigar of yours. But we shan't want to produce it in
evidence or rely on it in any way for the purposes of the prosecution;
which is as well, for it wouldn't have been particularly convincing
to the jury. But there is one more point which makes this find
extraordinarily complete. It is in connection with this finger-, or
rather, thumb-print. You probably know that we started, some time ago,
a special collection of finger-prints--mostly single impressions--known
as the 'Scene of the Crime Series.' They are either originals or
photographs of prints that have been found at places where a crime
has been committed, but where the criminal has got away without being
recognized. Most of them are, naturally, the prints of known men.
But there are a few prints that we cannot associate with any known
criminal. We can't put a name to them.

"Now, in this collection we had three sets of prints which had been found
on premises that had been broke into, evidently by a burglar of rather
exceptional skill and ingenuity, who seemed to have worked alone, and
whose technique we thought we recognized in several other jobs in which
no finger-prints were found. For some reason, when we got Smith's
finger-prints from Maidstone and found that they were not in the general
collection, the officer in charge omitted to try them with the 'Scene of
the Crime Series.' But, since then he has made the comparison, and it
turns out that those three sets of prints are undoubtedly Mr. Charles
Dobey's. So, now, we are able to identify him as that peculiarly talented
burglar."

"Is there any special advantage in being able to do so?" Thorndyke asked.
"I take it that you will proceed on the murder charge."

"Certainly we shall," Miller replied. "But there is the question of
identification. We have got to make it quite clear that the man who got
into the train at Strood was this same Charles Dobey. And then there is
the question of motive. Badger was the only officer who knew Dobey by
sight. He went down to Maidstone that very day for the express purpose of
identifying him."

"You are not forgetting that you cannot produce any evidence that he ever
did identify him?"

"No, I am not forgetting that. But he went down, having judged from the
description that Frederick Smith was the man who had committed those
various burglaries. And it now turns out that he was right. These
finger-prints prove that Dobey was the man."

"It seems to me," said I, "that the fact that the stolen paper was found
in his possession will be sufficient, unless it can be rebutted, to
establish the case for the prosecution, without referring to the
burglaries at all. You can't include them in the indictment--not in an
indictment for murder--and if you attempt to introduce them, and if the
court allows you to, you will have to prove them, which will complicate
the issues."

The Superintendent admitted the truth of this, but said that he was not
going to take any chances.

"And, at any rate," he concluded, "you must agree that we have got a
remarkably complete case."

Thorndyke did agree, and with so much emphasis that, once more, Miller
looked at him with a shade of anxiety.

"I know what you are thinking, Doctor," said he. "You are thinking that
it is too good to be true."

"Not at all," Thorndyke disclaimed with a smile, "though you must admit,
Miller, that he has made things as easy for you as he could."

"He certainly behaved rather like a fool," Miller conceded; "that is
often enough the way with crooks. You don't see any snags, do you?"

"No," replied Thorndyke. "It looks all perfectly plain sailing. All you
have to do now is to catch your hare; and he doesn't seem to be a
particularly easy hare to catch."

"I don't think we shall have very much difficulty about that," said
Miller. "He is an easy man to describe, and we shall circulate his
description all over the country; in fact, we have done so already."

"Yes," said Thorndyke, "that was what I meant. You had him placarded at
all the police-stations throughout the land, and then you find him
engaged in breaking and entering in the very heart of London."

Yet again, Miller glanced with a trace of uneasiness at Thorndyke; but he
made no comment on what sounded a little like a rather cryptic hint, and
shortly afterwards rose and took his departure.

When he had gone, I was disposed to continue the discussion, but my
colleague showed no enthusiasm. Yet I could see that he was reflecting
profoundly on what the Superintendent had told us; which encouraged me to
make a last effort.

"After all," I said, "we can't ignore plain fact. This story of
Miller's is difficult to reconcile with we know--with regard to that
cigar, for instance--but it is a consistent body of evidence, each item
of which can be proved beyond question. And the discovery of that paper
in the man's possession seems conclusive as it is possible for evidence
to be. In view of your very convincing argument, it does really appear
as if the solution of your problem is, x = Charles Dobey. Or is there
some fallacy in Miller's case?

"There is no obvious fallacy," Thorndyke replied. "The case presents, as
you say, a perfectly consistent body of evidence. Taken at its face
value, Miller's case is conclusive. The real question is whether the
completeness and consistency are the results of unaided chance or of an
ingeniously devised plan. It is a question we are, at present, unable to
decide. Perhaps, when Dobey is brought to trial, he may be able to
produce some new facts that may help us to come to a conclusion."

As this seemed to close the discussion, I knocked out my pipe and glanced
at my watch.

"Time for me to be moving on," said I, "if I am to get home within the
permitted hours. I told Juliet that I should be home to-night. And, by
the way, I have a message for you. I am instructed to remind you that it
is quite a long time since you paid your last visit."

"So it is," he admitted. "But we have not had many spare afternoons
lately. However, to-morrow afternoon is free. Do you think it would be
convenient to Juliet if I were to call and pay my respects then?"

"I happen to know that it will, as I took the precaution to ask what
afternoons were unengaged. Then I will tell her to expect you, and you
had better turn up as early as you can. She always looks for a long
pow-wow when you come."

"Yes," he replied, "she is very patient of my garrulousness. Then I will
come as early as possible, and prepare myself for a special
conversational effort. But it is really very gracious of her to care for
the friendship of an old curmudgeon like me."

"It is," I agreed. "Odd, too. I can't imagine why she does."

With this Parthian shot, and without waiting for a rejoinder, I took
myself off en route for the Temple station.

Here, perhaps, since my records of Thorndyke's practice have contained so
little reference to my own personal affairs, I should say a few words
concerning my domestic habits. As the circumstances of our practice often
made it desirable for me to stay late at our chambers, I had retained
there the bedroom that I had occupied before my marriage; and, as these
circumstances could not always be foreseen, I had arranged with my wife
the simple rule that the house closed at eleven o'clock. If I was unable
to get home by that time, it was to be understood that I was staying at
the Temple. It may sound like a rather undomestic arrangement, but it
worked quite smoothly, and it was not without its advantages. For the
brief absence gave to my homecomings a certain festive quality, and
helped to keep alive the romantic element in my married life. It is
possible for the most devoted husbands and wives to see too much of one
another.

Thorndyke redeemed his promise handsomely on the following afternoon, for
he arrived shortly after three o'clock, having, I suspect, taken an early
lunch to that end; for it presently transpired that he had come straight
from Scotland Yard, where he had been conferring with the experts of the
Finger-print Bureau.

"Was your pow-wow concerned with any particular case that we have in
hand?" I ventured to enquire.

"No," he replied. "I went there to get some further information
respecting the new system of dealing with single finger-prints that was
devised by Chief Inspector Battley. I have been studying his book on his
method of classification and making a few tentative trials. But I wanted
to make sure that my application of the method yielded the same results
as were obtained by the experts. So I went to Scotland Yard and asked
them to check my results."

"I suppose," my wife suggested, "you are still a good deal interested in
finger-prints?"

"Yes," he replied, "almost necessarily, since they so constantly crop up
in evidence. But apart from, that, they are curious and interesting
things in a number of ways."

"Yes," she agreed, "interesting and curious and rather horrible--at
least that is how they appear to me. I never hear of a finger-print but
my thoughts go back to that awful trial, with Reuben in the dock and poor
Aunt Arabella in the witness-box giving evidence about the Thumbograph.
What a dreadful time it was!"

I am afraid I was disposed to grin at the recollection, for poor Mrs.
Hornby had brought the proceedings as near to farce as is humanly
possible in a criminal trial where an honourable gentleman stands
indicted for a felony. But I controlled my features, and, as to
Thorndyke, he was, as usual, gravely sympathetic.

"Yes," he agreed, "it was an anxious time. I was not at all confident as
to how my evidence would be received by the judge and the jury; and, if
they had failed to be properly impressed, Reuben would certainly have
gone to penal servitude. By the way, we sent the Thumbograph back to Mrs.
Hornby after the trial. Do you happen to know what she did with it?

"She didn't do anything with it," Juliet replied, "because I annexed it."

"What for?" I asked, rather foolishly, perhaps.

"Can't you imagine?" she demanded, flushing slightly. "It was a little
sentimental of me, I suppose, but I kept it as a souvenir. And why not?
It had been a terrible experience, but it was over, and it had ended
happily, for me, at any rate. I have something to thank the Thumbograph
for."

"It is very nice of you to say that, Juliet," said I. "But why have you
never shown it to me? I have at least as much to be thankful for, though,
to tell the truth, I had overlooked the fact that it was the Thumbograph
that introduced us to one another."

"Well," said Thorndyke, "suppose you produce this disreputable little
matchmaker and let us revive our memories of those stirring times. I
haven't seen a Thumbograph for years."

"I am not surprised," said Juliet. "The report of your evidence at the
trial was enough to kill the demand for them for ever. But I will go and
fetch it."

She went away and returned in a minute or two with the souvenir, which
she handed to Thorndyke; a little oblong volume, bound in red cloth with
the name "Thumbograph" stamped in gold on the cover. I looked at it with
a new interest as Thorndyke turned over the leaves reminiscently while
Juliet looked over his shoulder.

"Doesn't it bring all those horrors back?" said she, "and especially poor
Mrs. Hornby's evidence. Here is Miss Colley's thumb-print, which Reuben
was supposed to have smeared, and here is Aunt Arabella's, and here is
mine, and there is that wretch Walter's."

"Characteristically, the best impression in the book," said Thorndyke.
"He was a remarkably capable scoundrel. He did everything well."

"I wonder if we shall ever see him again?" I mused. "When he slipped away
from the court, he seemed to vanish into thin air."

"Yes," said Thorndyke; "another instance of his capability. It is not so
very easy for a man who is badly wanted by the police to disappear, once
and for all, as he did."

He turned over the leaves once more until he came to the one which bore
the print of Reuben Hornby's thumb. Underneath it Reuben's name was
written in pencil and, below this, the signatures of the two witnesses,
"Arabella Hornby" and "Juliet Gibson."

"Do you remember," said Juliet, "the night Aunt Arabella and I brought
the Thumbograph to your chambers? It was a thrilling experience to me."

"And to Thorndyke too, I imagine," said I. "For it was then that he knew
for certain that the Red Thumb Mark was a forgery. I saw him make the
discovery, though I did not know at the time what the discovery was.
Wasn't it so, Thorndyke?"

"It was," he replied. "And what was even more important, I thought I had
found the means of convincing the court. You are quite right, Juliet; it
was a memorable occasion for me."

As he continued to turn over the leaves and scrutinize the various
thumb-prints, I reverted to our previous conversation.

"I don't quite understand what you were doing at the Yard to-day," said
I. "The classification of finger-prints is interesting enough in its way.
But it doesn't specially concern us."

"It doesn't concern us at all," he agreed. "But identification does. And
that is where Battley's method is valuable to us. The beauty of it is
that, apart from classification for index purposes, it affords a means of
rapid identification, and moreover makes it possible to express the
distinctive characters of a given finger-print in a formula. Now this is
an immense convenience. We often have occasion to identify a finger-print
with an original or a photograph in our possession. But we can't always
carry the print or photograph about with us. But if we can express the
characters of the print in a formula, we can enter that formula in our
note-books, and have it ready for reference at any moment."

"But," I objected, "a formula would hardly be sufficiently definite for a
reliable identification."

"Not, perhaps, for a final identification to swear to in evidence,"
he replied, "though you would be surprised at the accuracy that is
possible. But that is not the purpose aimed at. The use of the method
at the Bureau is principally to enable the searchers to find a given
finger-print quickly among the thousands in the collections of single
finger-prints. Our use of it will be to form an opinion rapidly on the
identity of a print in which we happen to be interested. Remember,
we don't have to give evidence. Finger-print evidence, proper, is
exclusively the province of the regular experts. We have only to form
an opinion for our own guidance. Come," he continued, "I have the
apparatus in my bag, which is in the hall, and here is the Thumbograph
with a selection of prints to operate on. Why shouldn't we have a
demonstration of the method? You will find it quite amusing."

"It does sound rather thrilling," said Juliet; and, thus encouraged by
the vote of the predominant partner, Thorndyke went out to find his bag.

"Let me first explain the general principle of the method," said he, when
he returned with a small leather bag in his hand. "Like all really
efficient methods, it is essentially simple though extremely ingenious.
This is the sole apparatus that is necessary."

As he spoke, he opened the bag and took out a magnifying glass, which was
mounted on three legs, the feet of which were fixed into a brass ring
which enclosed a plate of glass.

"This circular glass plate," he explained, "is the essential part of the
instrument. If you look through the lens, you will see that the glass
plate has engraved on it and coloured red a central dot surrounded by
seven concentric circles. The first circle is three millimetres from the
dot; the other circles are each two millimetres from the next. The
central space is denoted by the letter A. The spaces between the other
circles are denoted, successively, by the letters B, C, D, E, F, and G;
and the space outside the outermost circle is denoted by H. The letters
are, of course, not marked on the glass; but I have here a diagram which
shows their position."

He laid on the table a card on which were described the seven circles,
each marked with its appropriate letter, and then, taking up the
Thumbograph, once more turned over the leaves.

"I think," said he, "we will select the estimable Walter's thumb-print as
the corpus vile for our experiment. It is the best print in the book, and
it has the further advantage of being a peculiarly distinctive type with
a rather striking pattern. It has the general character of a whorl with a
tendency towards that of a twinned loop--that is, a pair of loops folded
into each other with the convexities turned in opposite directions. But
we will call it a whorl, and treat it as such, merely noting the
alternative character. You will see that the pattern is formed by a
number of black lines, which are the impressions of the ridges on the
thumb. In this print the centre of the patterns, or 'core,' consists of a
pair of little loops, from which the lines meander away in a rather
irregular spiral. At a little distance from the core, these lines meet
another set of lines at an angle, forming a Y-shaped figure known as a
'delta.' There will be another delta on the opposite side of the thumb,
but it is too far round to appear in this print. It would be visible in
a 'rolled impression'--that is, a print made by rolling the inked thumb
over on a card or paper; but in this print, made by a single contact,
only the right delta appears.

"And now as to the use of the instrument. We lay the glass plate on the
print, so that the dot just touches the top of the upper loop. And now
you see the masterly simplicity of the method. For, since a circle has no
right or wrong way up, when once you have set the dot in the appointed
place, all the other lines must be correctly placed. Without any further
adjustment, they show with absolute accuracy the distance from the centre
of any part of the pattern. And this distance can be expressed, quite
unmistakably, by a single letter."

He placed the instrument on the thumb-print in the book, and, having
carefully adjusted it, drew out his note-book and looked at my wife.

"Now, Juliet," said he, "just look through the lens and tell me the
letter that indicates the position of the delta--which is actually the
right delta, though it is the only one visible."

Juliet peered through the magnifying glass and studied the print for a
while. At length, she looked up a little doubtfully and announced:

"It seems to me that the third line cuts right through it. So it lies
half in the space C and half in D. Which of the two would you call it?"

"The rule," he replied, "is that if a character is cut by a line, it is
reckoned as lying in the space outside that line."

"Then this delta lies in the space D," she concluded.

"Quite right," said he. "We will mark it D; and, as the other delta is
not in the print, we must mark it simply with a query. And now we proceed
to the rest of the examination, the ridge-tracing and ridge-counting. We
will take the tracing first. What you would have to do if both the deltas
were visible would be to follow the ridge that runs from the left delta
towards the right. Obviously, it must take one of three courses: it may
pass below, or outside, the right delta, or below, or inside, or it may
meet, or nearly meet, the corresponding ridge from the right delta. Those
are the three categories: outside, inside, or meeting, by the initials,
I, M, O."

"But," objected Juliet, "as the left delta is not visible, it is
impossible to trace a ridge from it."

"That might be true in some cases," replied Thorndyke, "but it is not in
this, for, if you look at the print, you will see that, wherever the left
delta may have been, a ridge passing from it towards the right must have
passed well outside the right delta."

Juliet examined the print again and agreed that it was so.

"Very well," said Thorndyke, "then we will mark it O, and proceed to the
ridge-counting, which will complete the formula. You have to count the
ridges between the centre of the core and the delta. Put aside the
measuring glass and use my lens instead; and I will give you a point to
help you to count the ridges."

He handed her his pocket lens, and produced from his bag what looked
suspiciously like a dentist's excavator, with the sharp point of which he
indicated the ridges that were to be counted. Then he laid a
visiting-card on the print to give a straight line from the centre to the
delta, and she proceeded to count along its edge with the point of the
excavator. Having gone over the ground twice, she announced the result.

"I make it twelve. But I am not quite sure, as some of the ridges fork,
and might be counted as one or two. Will you count them?"

Thorndyke took the excavator from her and rapidly checked her result.

"Yes," said he, "I agree with you. I think we may safely put it down as
twelve, though the bifurcations do, as you say, create a slight
ambiguity. If the other delta had been visible there would, of course,
have been a second circle-reading and a second ridge-count, which would
obviously have been an advantage for identification. Still, what we have
done gives us the main distinctive characters of this print, and we can
express them by a simple formula of a few letters and numbers. Thus, the
type of pattern is a whorl, with something of the character of a twinned
loop. Accordingly, we put down a W with T.L. in brackets. The core, or
central character--the pair of little, loops--lies entirely in
the circle A. Now, there are five kinds of 'A' cores: the plain
eye--just a tiny circle--the eye enclosing some smaller character, the
left-hand spiral, the right-hand spiral, and any other 'A' form of
an unclassifiable type. Now, in this print, the core is a left-hand,
or anti-clockwise spiral, and accordingly belongs to the category
A3. The delta, we agreed, lies in the space D. The ridge-tracing was
outside--O--and the ridge-count twelve. We can express all these facts
in a formula, thus:

"Walter Hornby. Right thumb. W (? T.L.), A3, ?, O, D, ?, 12."

"That is concise enough," I remarked. "But, after all, it gives you only
a skeleton of the pattern. It would not enable you to identify a print
with any approach to certainty."

"It does not aim at certainty," he replied, "but merely at such a degree
of probability as would justify action or further research. But I think
you hardly appreciate the degree of probability that this formula
expresses. It records five different positive characters and one
negative. Now, taking the five only, if we accept the very modest chance
of four to one against each of these characters being present in a print
which is not Walter Hornby's, the cumulative effect of the five together
yields a chance of over a thousand to one against the print being that of
some person other than Walter Hornby.

"But, for our purposes, we are not obliged to stop at these five
characters. We can add others; and we can locate those others either by
the use of Battley's circles or by ridge-counting with a direction-line.
For instance, in this print, to the left of the core and a little
downwards, the seventh ridge shows one of those little loops known as
'lakes,' the ninth bifurcates, and the eleventh has another, larger lake.
To the right of the core the third ridge has a small lake, the fifth
ridge bifurcates, the eighth has a free end, and the tenth bifurcates.
There are seven additional characters which we can add to our formula,
giving us twelve characters in all, the cumulative effect of which is a
probability of over sixteen millions to one against the print being the
thumb-print of any person other than Walter Hornby, and that is near
enough to certainty for our purpose. It would undoubtedly justify an
arrest; and we could leave the final proof or disproof to the experts."

He added the extra characters to the formula in his note-book, and
showed us the completed entry; which certainly afforded convincing
testimony to the efficiency of the method. In fact, it impressed
me--and my wife, too--so profoundly that, in an access of enthusiasm,
we fell upon the Thumbograph forthwith, and with the aid of Chief
Inspector Battley's ingenious instrument, proceeded to construct
formulas to express the characters of the other thumb-prints in the
book, while Thorndyke smoked his pipe regarded our activities with
benevolent interest, seasoned by occasional advice and criticism of the
results.

"It is quite an amusing game," Juliet remarked. "If only the inventors of
the Thumbograph had known of it and printed directions in the book, it
might have become a fashionable drawing-room pastime, and they would have
made a fortune."

"Perhaps it is as well that they did not," said I. "The Thumbograph was a
dangerous toy, as we discovered--or rather, as Thorndyke did."

"Yes," Thorndyke agreed, "it was a mischievous plaything. But don't
forget that it acted both ways. If it supplied the false accusation, it
also supplied the conclusive answer. Walter Hornby had more reason than
any of us to regret that he ever set eyes on the Thumbograph. And it may
be that he has not yet come to the end of those reasons. He has evaded
justice so far. But the debt is still outstanding."


BOOK III.


Chapter X: Mr. Woodburn's Story

INVENTORS are a much-misunderstood class. The common man, in his vanity
and egotism, supposes that they exist to supply him with various
commodities of which he dimly perceives the need. But this is an entirely
mistaken view. The inventor produces his invention because, in the
existing circumstances, it has become possible. It is true that he,
himself, tends to confuse the issues by persuading himself optimistically
that his invention has a real and important utility. His inventive mind
goes so far as to create an imaginary consumer, so that he sees life in a
some what false perspective. The genius who devised a family Bible which
could be opened out to form a billiard table, no doubt envisaged a pious
type of player who had need of some means of combining the canon of
scripture with a cannon off the red; while, to the inventor of a super
magic-lantern which could throw pictures on the clouds, the night sky was
no more than a suitable background on which to declare the glory of
Blunt's Milky Toffee.

But this is mere self-delusion. In reality, the inventor is concerned
with his invention. Its use is but a side issue which hovers vaguely on
the periphery of his mental field of vision. I emphasise the fact,
because it has a bearing on the events which I am recording. For our
invaluable laboratory assistant, Polton, was an inveterate inventor, and,
being also an accomplished and versatile craftsman, was able to turn out
his inventions in a completely realised form.

So it happened that a certain large cupboard in the laboratory was a
veritable museum of the products of his inventive genius and manual
skill; examples of ingenuity--sometimes fantastically misguided--the
utility of which he would expound to Thorndyke and me with pathetic
earnestness and appeals to "give them a trial." There were spectacles
which enabled the wearer to see behind him, there was a periscope
walking-stick with which you could see round a corner, a large pedometer
with movable dials for metres and yards and a micrometer adjustment of
impracticable accuracy, and all sorts of clockwork devices and appliances
for out-of-the-way photographic operations. But optical instruments were
his special passion, whence it followed that most of his inventions took
an optical turn.

I am afraid that I did not treat these children of Polton's imagination
with the respect that they deserved. Thorndyke, on the other hand, made a
point of always examining even the wildest flights of the inventor's
fancy with appreciative attention, realizing--and pointing out to me--that
their apparent oddity was really due to the absence of appropriate
circumstances, and that those circumstances might arise at any moment and
give an unexpected value to what seemed to be a mere toy. And that was
what happened on the present occasion. One of Polton's most eccentric
productions suddenly revealed itself as an invaluable instrument of
research. But perhaps I am beginning the story at the wrong end. I had
better turn back and take the incidents in their proper order.

It was rather late one afternoon when there arrived at our chambers a
dapper, well-dressed gentleman of distinctly horsey appearance, who gave
the name of Woodburn, and who, rather to my surprise, turned out to be a
solicitor. He presented Mr. Brobribb's card, on which were scribbled a
few words of introduction.

"I have come to see you," he explained, "on the advice of my friend
Brodribb. I came up to Town expressly to confer with him on a rather
queer case that has turned up in my practice. We talked over the legal
issues without coming to any very definite conclusion, but Brodribb
thought that there were certain points in the case that were more in your
line than in either his or mine. And I am certainly inclined to agree
with him to the extent that I am decidedly out of my depth."

"And what about Mr. Brodribb?" Thorndyke asked. "He is a pretty acute
lawyer."

"He is," Mr. Woodburn agreed, heartily. "But this is not altogether a
question of law. There are some other points on which he thought you
would be able to help us. I had better give you an outline of the case.
But, first, I had better explain that I am a country practitioner with my
principal office at Packington in Kent, and that my clients are chiefly
the farmers and country gentlemen of the surrounding district.

"Now, one of these clients is a gentleman named Mr. Didbury Toke. He is a
sort of superior dealer in works of art and antiquities. He has an office
in Town, but he resides at an ancient house called Hartsden Manor in the
village of Hartsden and usually spends a good deal of his time there. But
from time to time he has been in the habit of taking more or less
prolonged trips to the Continent for the purpose of rooting about for
antiques and works of art. On these occasions it has been his custom to
shut up that part of the house in which his collection is lodged, and
seal all the doors and windows in any way giving access to it.

"Well, about two months ago, he set forth on one of these expeditions,
and, according to his usual custom, he locked up and sealed all the
approaches to the rooms containing the collection and gave the keys into
my custody."

"What happened to the seal?" asked Thorndyke.

"That I can't tell you," replied Mr. Woodburn. "He didn't give it to me,
but I have an impression that he deposited it at his bank in London. I
know that he did on a previous occasion. Still, he may have carried it on
his person. I happen to know that it is a large, clumsy, antique ring,
which he was certainly not in the habit of wearing.

"Well, as I said, he handed the keys to me, but, at the same time, he
gave me very definite instructions--in writing--that the rooms were not
on any account to be entered or the seals tampered with in any way. You
see that his instructions were quite explicit, and, in fact, decidedly
emphatic."

"Apparently," said Thorndyke, "he allowed you no discretion and provided
for no contingencies. Is that not so?"

"That is so," replied Mr. Woodburn. "His instructions amounted to an
absolute prohibition of any interference with the seals or any attempt to
enter the enclosed rooms. That is the matter which I have be discussing
with Mr. Brodribb, and which I want to discuss with you. Because this
prohibition has become highly inconvenient. Circumstances have arisen
which seem to make it very desirable to enter those enclosed rooms. But
before I go into those circumstances, I had better tell you a little more
about the arrangements of the house and those particular rooms.

"The main part of the closed premises consists of a very large
room--about forty feet long--called the great gallery; but adjoining
this are three or four smaller rooms, some of which are used to house
part of the collection, and some are kept as workrooms, in which Mr.
Toke does his mending and other odd jobs connected with the collection.
The great gallery and the rooms attached to it occupy the whole of a
wing which runs at right angles to the rest of the house; and, as there
is only one door giving access to the gallery and its annexed rooms,
the whole group of apartments is completely cut off and isolated.

"Now the circumstances to which I referred are these. Mr. Toke's
household ordinarily consists of his housekeeper and her niece, who acts
as housemaid; but, when he is away from home, a nephew of the housekeeper
usually comes to stay there, so that there may be a man on the premises.
He is there now; so there are three persons living in the house; and
those three persons are agreed that, from time to time, they have heard
sounds at night apparently coming from the great gallery. It sounds
incredible, and I must admit that when they first reported the matter to
me, I was disposed to be sceptical. I am not entirely unsceptical now.
But they are extremely positive, and, as I said, they are all agreed. So
I thought it my duty to go over to the manor house and make an
inspection; and the result of that inspection was only to make the whole
affair still more incomprehensible. For the seals were all intact, and
there was not a sign anywhere of anyone having broken into the place."

"You examined the windows, of course?" said Thorndyke.

"Yes. There are five large windows, and I examined them all from outside
by means of a ladder. They certainly had not been opened, for I could see
that the catches were all in their places. But I may say that the windows
are all secured from inside with screws,  and those screws are sealed.
Mr. Toke leaves nothing to chance."

"Could you see into the room?" asked Thorndyke.

"No. The shutters were not closed, but the windows are covered by lace or
net curtains, so that, although the gallery is quite light, it is
impossible to see in from the outside."

"You have spoken of the collection," said Thorndyke. "Perhaps you had
better tell us something about its nature and value."

"As to its value," said Mr. Woodburn, "I believe that is very
considerable, but as it consists chiefly of pottery and porcelain, Bow
and Chelsea figures, bronzes, and small statuary, it would be of no
interest, to a burglar--at least, that is what I understood from Mr.
Toke."

"I am not sure that I agree with Mr. Toke," said Thorndyke. "Of course,
since you cannot melt down porcelain figures into unrecognizable
ingots, they are not suitable for the common type of burglar. The
ordinary 'fence' would not trade in them, and they could not be offered
in the open market. But they are really valuable things and fairly
portable, and they would not be so very difficult to dispose of. The
ordinary collector is not always as scrupulous as he might be, but
there is one kind of collector who is not scrupulous at all. One may
take it that a millionaire who has made his millions by questionable
transactions, may be prepared to spend them in a like manner. The point
is of some importance; for, whereas the repeated occurrence of these
sounds--assuming them to have occurred--is not consistent with the idea
of an ordinary burglary, it does suggest the bare possibility of some
enterprising persons quietly removing the more valuable parts of the
collection piecemeal."

"You do, then, really entertain the possibility that these sounds are not
merely imaginary?"

"I have an entirely open mind," replied Thorndyke. "But I understood you
to say that you had gone into the question of fact on the spot, and that
you were satisfied that the reports were sufficiently convincing to
justify serious enquiry."

"That is so," said Mr. Woodburn. "But I may say that Brodribb scouted the
idea. He was incredulous as to the sounds having been heard at all,
seeing that the closed rooms are so completely isolated and so distant
from the rest of the house; and he suggested that if there had been any
sounds, they were probably due to rats. I don't agree with him as to the
rats. Of course, I enquired whether that could be the explanation, but I
think it can be excluded. The noises that rats make are pretty
characteristic, and they don't at all agree with the description of the
sounds that these people gave. And they tell me that there are no rats in
the house, which seems to settle the question; for, although rats will
harbour in empty rooms, they don't stay there. They must come out for
food. But Brodribb's other objection is more weighty. The great gallery
is a good distance from the rest of the house. What do you really think
of the probabilities?"

"Well," replied Thorndyke, "the answer to your question involves the
statement of a rather bald truism. If there is no access to the closed
rooms other than the door of which you spoke, and that door is still
locked and the seal is still unbroken, evidently no one can possibly have
entered those rooms. On the other hand, if sounds have been heard of such
a nature as to make it certain that someone had entered those rooms, then
it follows that there must be some means of access to those rooms other
than those which are known to you. I apologize for the obviousness of the
statement."

"You needn't," said Mr. Woodburn. "It puts the matter into a nutshell. I
saw the dilemma myself. But what do you suggest?"

"In the first place," said Thorndyke, "may I ask if it is impossible to
get into touch with Mr. Toke?"

"Ah," said Mr. Woodburn, "there you have raised another point,
Apparently, it is impossible for me to get into touch with my client; and
that is a matter that I am not entirely happy about. Mr. Toke is by no
means a good correspondent. But, when he is travelling, as a rule, he
sends me a short note now and again, just to give me the chance of
communicating with him if the occasion should arise. And he has been in
the habit of sending me parcels--purchases that he has made--to put in
my strong room or to deposit at his bank. But this time, I have had not a
single line from him since he went away. It is really rather strange, for
Mr. Toke is a methodical, business-like man, and he must realize that it
is most undesirable that his solicitor and man of business should have no
means of communicating with him. It might be extremely awkward; even
disastrous. It is extremely awkward now. If I could get into touch with
him, he would pretty certainly authorize me to break the seals and see if
his collection is all as it should be. As he can't, the question arises
as to what I ought to do. Should I, for instance, take it that these
exceptional circumstances absolve me from the obligation to abide
literally by his instructions? Brodribb thought not. What is your view of
the case?"

"I am disposed to agree with Brodribb. The difficulty seems to be that
you have not established the exceptional circumstances. There is only a
suspicion; and Mr. Toke might think, as Brodribb does, that the suspicion
was not a reasonable one. You have said that Mr. Toke's instructions were
very explicit and even emphatic. He was clearly most anxious that those
rooms should not be entered or the seals broken. He has said so, and he
has given quite definite instructions on the subject. This being so, we
must assume that he had good and sufficient reasons for giving those
instructions. We cannot judge what those reasons were, or how strong they
were. But it is always safe to assume that a man means what he says,
especially when he says it quite clearly and unmistakably.

"Suppose you 'interpret' his instructions and proceed to break the
seals and enter the rooms. Suppose you find everything normal, and,
at the same time, find something that shows you that the rooms ought
not to have been entered by anyone except Mr. Toke himself. That might
create a very awkward situation."

Mr. Woodburn laughed. "You think it possible that Mr. Toke may have
something hidden in those rooms that he wouldn't like anyone else, to
see? Well, of course, it may be so. But I may mention that Mr. Didbury
Toke is a most respectable gentleman."

"I am not suggesting the slightest reflection on Mr. Toke's moral
character," said Thorndyke, laughing in his turn. "Probably, his motive
was nothing more than extreme solicitude for his collection. Still, he
may have things locked up in his gallery the existence of which, in that
place, he might well wish to keep secret; things, for instance, of great
intrinsic value which might invite the attentions of burglars."

"Yes," said Woodburn, "I suppose you are right. He always swore that
there was nothing there that a burglar would look at. But that may have
been a mere precaution. Which brings us back to the question, What is to
be done?"

"I think the answer to that is fairly simple," said Thorndyke. "These
statements certainly call for investigation. Two points require to be
cleared up. First, is it certain that there is really no possibility of
access to these rooms other than the door that you mentioned? And,
second, assuming the first to be true, is it certain that access has not
been obtained by means of that door?"

"But how could it have been?" Mr. Woodburn exclaimed. "The door is
sealed. I examined it most carefully, and I can assure you that the seals
are undoubtedly intact."

"That is not absolutely conclusive," Thorndyke replied with a faint
smile. "Seals are not difficult to counterfeit. For instance, if, for any
legitimate purpose you asked me to enter those rooms and replace the
seals when I came out, I should find no difficulty in doing so."

"Really!" exclaimed Mr. Woodburn. Then, subsiding into a grin, he added:
"You are a rather dangerous sort of person, but I am not surprised that
Brodribb has so much confidence in you. Perhaps you can suggest some way
in which I might set about testing the correctness of these statements;
or, better still, perhaps you would be willing to undertake the
investigation yourself? I do feel that something ought to be done."

"So do I," said Thorndyke. "Incredible as the statements sound, what is
stated is by no means impossible. And, if we should find that some
persons either could have effected an entrance or had actually done so,
the position would be entirely changed. You would then certainly be
justified in breaking the seals and entering the rooms."

"And asking you to replace the seals after, eh?" suggested Woodburn, with
a broad grin. Apparently, Thorndyke's accomplishments had made a profound
impression on him.

Thorndyke smilingly dismissed the suggestion and enquired: "Is there no
way, so far as you know, of getting a glimpse into the room from the
outside?"

"No way at all," was the reply. "I tried peering in at the windows, but
it was impossible to see any thing through the curtains. I even tried the
keyhole. There is a monstrous great keyhole in the door. I myself should
think the key must be quite a formidable weapon, though I have never seen
it. The door is secured by a Chubb lock, of which I have the key. Well, I
peered through that keyhole, but all I could see was a patch of wall on
the side of the room opposite. Naturally; because the door opens into the
room at the extreme end of one side."

"Could you give me a description of the room, or, preferably, a sketch?"
Thorndyke asked.

"I have an architect's plan of the house in my bag," Woodburn replied. "I
brought it up to show Brodribb, but he was not interested, as he did not
believe the story. However, you are not so sceptical. I'll get it out."

He rummaged in his bag and presently produced a small roll of
tracing-cloth, on which was a clearly drawn plan of the house and its
immediate surroundings.

"The scale of the particular room," he remarked, "is not as large as we
should like. But you can see the main features. This crooked corridor
leads to the gallery wing, and you see that it ends in a turn at right
angles. So, when the door is open, you look in across the end of the
room. The door opens inwards, and there are three steps down to the floor
level. You can see for yourself that a keyhole in that door is of no use
for the purpose of inspection."

"Can you tell us anything about the furniture, or how the floor space is
occupied?" Thorndyke asked.

"With the exception of a few chairs and a large table across the farther
end of the room, there is practically no furniture excepting the
wall-cases. There is range of them along each side wall between the
windows, and the two doors that open into the four small rooms at the
side of the gallery."

"There seems to be no access to those rooms excepting through the doors
from the gallery."

"No, there is not. Those rooms seem to have been originally a corridor,
which has been divided up by partitions. They all open into one another--at
least, each opens into the next. Two of them have cabinets full of
pottery and porcelain, and the other two are work-rooms in which Mr. Toke
does jobs such as mending and cleaning the pieces."

"What is there above and below the gallery?" asked Thorndyke.

"Above, I suppose, are lofts. I don't know how you get to them, but I
don't think they would help us. You couldn't see through the floor, and
you couldn't bore holes in it, as the gallery has a fine
seventeenth-century plaster ceiling. Under the gallery is a range of
cellars, but they are not accessible, as they are all secured with good
padlocks, and both the padlocks and the doors are sealed."

"Mr. Toke was certainly pretty thorough in his methods," Thorndyke
remarked. "It would be a serious responsibility to break into his
Bluebeard chambers."

"Yes, confound him," Woodburn agreed. "I wish to goodness it was possible
to communicate with him and let him take the responsibility. I wonder why
the deuce he has never sent me a line. I hope nothing has happened to him
abroad. You can never be sure in these days of motors and sudden death."

"When did you say he went away?" Thorndyke asked.

"On the ninth of August," replied Woodburn, "at least that is the date he
gave me. He came to my office on the eighth to give me the keys and his
final instructions, and he then said that he intended to start for Paris
on the following night."

"Do you know if he did actually start then?"

"Well, yes--indirectly. I happen to use the same garage to put up my
car, when I come to town, as Mr. Toke uses. He recommended it to me, as a
matter of fact. There I ascertained that he deposited his car on the
morning of the ninth of August. But, oddly enough, he took it out again
in the evening, and it was not returned until some time in the small
hours of the following morning."

"Then," I said, "he couldn't have caught his train."

"I think he did. He did not return the car himself. It was brought in by
a stranger, whom the night watchman described, picturesquely, as a
'ginger Lushington,' and this person reported that Mr Toke had caught his
train, and that the lateness of the delivery of the car was due to some
fault of his own."

"I wonder what the watchman meant by a 'ginger Lushington'?" said I.

"Yes," said Woodburn, "it is a quaint expression. I asked him what it
meant in common English. Apparently, it was a term of inference. The word
'ginger' referred to the colour of the man's hair, and, as his nose was
tinted to match, the watchman inferred the habitual use of stimulants.
But apparently Toke caught his train all right."

As Mr. Woodburn interpreted the watchman's description, I caught
Thorndyke's eyes for a single instant, and I saw that he had noted the
significance of that description. It was probably the merest coincidence,
but I knew that it would not pass without close scrutiny. And I could not
but perceive that thereafter his interest in Mr. Woodburn's affairs
became appreciably more acute.

"Do I understand," he asked, "that you feel an actual uneasiness about
your client?"

"Well," was the reply, "I must admit that I am by no means happy about
him. You see, this prolonged silence is a complete departure from his
usual habit. And time is running on. This is the eleventh of October, and
he has made no sign. All sorts of thing may happen to a man who is in a
strange country and out of all touch with his friends. I don't like it at
all However, it was not about Mr. Toke that I came to consult you, though
I may have to ask for your assistance later. It is about these queer
happenings at the Manor House. Now, what do you suggest? I should like
you, as an expert, to take up the inquiry yourself. Do you care to do
that?"

"I am quite willing to make a preliminary investigation," Thorndyke
replied. "That would involve personally interrogating the servants and
making a careful survey of the premises. If it seems to be a mare's nest,
we can let it drop. But if we discover some hitherto unsuspected means of
access to the gallery, or find evidence that some persons have, in fact,
entered the premises, we can consider what action is to be taken. Would
that meet your views?"

"Perfectly," replied Woodburn. "When could you come down and take a look
at the place?"

"I suggest the day after to-morrow, early in the afternoon, if that will
suit you."

"It will do quite well," said Woodburn. "There is a good train from
Charing Cross at two-thirty. If you can catch that, I will meet you at
the station with my car and take you straight on to the house."

Thorndyke made a note of this arrangement, and Mr. Woodburn then took his
leave, evidently very well pleased at having transferred some of his
anxieties to more capable shoulders.

When he returned from the landing, having seen his visitor safely
launched down the stairs, Thorndyke picked up the plan, which Mr.
Woodburn had left on the table, and, glancing at it, turned to me with a
smile.

"A queer affair, Jervis," said he. "I wonder if there is anything in it?"

"Personally," I replied, "I should be disposed to suspect a mare's nest.
There is something a little creepy about a big, old house, especially if
a part of it is shut up and sealed. Those servants may easily have got a
trifle jumpy and imagined that they heard sounds in the dead of the
night."

"That is quite possible," he agreed. "But then we must not overlook the
fact that the thing alleged is also quite possible. And it is not so very
improbable. Precautions of the kind that Mr. Toke has taken may have a
certain boomerang quality. The place is locked, bolted, barred, and
sealed. That is all well enough so long as the precautions take their
expected effect. But if they fail, they fail with a most horrid
completeness. Here, for instance, is a collection of really valuable
things. It is all nonsense to say that they are of no interest to
burglars. It depends on the burglar. Fine pieces of porcelain and
high-class bronzes are easily negotiable in the right markets. The
burglar's real difficulty is in getting them away. Silver and gold can be
carried away regardless of injury, as they are to be melted down; but
these things are fragile, and their value depends on their being
uninjured. Now, if it is only possible for a burglar to obtain access to
Mr. Toke's gallery, everything else made easy for him. He can work at his
leisure and take these things away one or two at a time in the most
suitable manner. I think the affair is worth looking into, even on its
own merits.

"But you notice that there is another aspect of the case that deserves
attention. Woodburn is obviously anxious about Mr. Toke. And not without
some reason. In a legal sense, Mr. Toke has disappeared. His whereabouts
are unknown to the very man to whom they should be known. Now, suppose
that some mishap has befallen him, and suppose that circumstance to be
known to some person--some unscrupulous person--who also knows about
the collection. That is a bare possibility that has to be considered. And
then we have to note the fact that the only evidence that Toke did really
catch his train is the statement of an unknown stranger."

"Who happens to have had red hair and a red nose," I remarked.

Thorndyke chuckled. "True," he admitted. "But we mustn't allow ourselves,
like Miller, to be obsessed by a mere matter of complexion. Still, we
will bear even that fact in mind. And there is one other fact, with a
possible inference. Toke's instructions to Woodburn suggest something
more than mere caution. They have a suggestion of secrecy. So much so
that one asks oneself if it is possible that he may have some property
concealed in the gallery of a different kind from the ostensible
collection. I find it quite an attractive case, though, as you say, it
may easily turn out to be a mare's nest."

"What do you propose to do when you go down to Hartsden?" I asked.

"I have no definite programme," he replied, "beyond making the best
possible use of my eyes and ears. The obviously desirable thing would be
to get a look at the interior of the gallery, and see if there are any
signs of disturbance--whether, for instance, the cases have or have not
been emptied."

"Yes," I agreed, "I realize that; but I don't see how you are going to
manage it, as, apparently, it is impossible to see in either by the
windows or the door."

"It doesn't sound promising, I must admit," said he. "But we shall see
when we get there. Perhaps Polton may be able to help us."

"Polton!" I exclaimed. "How do you suppose that he may be able to help?"

"Don't be so scornful," he protested. "Is an inventor and mechanical
genius nothing worth? I shall certainly put the problem to him as soon as
I am clear about it myself."

In spite of the rather ambiguous phraseology, I suspected that Thorndyke
had something quite definite in his mind. But I asked for no particulars
long experience had taught me that he preferred to present his ideas in a
mature and complete form rather than in that of a preliminary sketch.
And, to tell the bald truth, my curiosity was not painfully acute. So I
could wait patiently for enlightenment to come in due course.

Chapter XI: Hartsden Manor House

As the train moved out of the station, Thorndyke lifted his invaluable
green canvas research case from the seat to the rack, and then, with the
tenderest care, disposed similarly of a walking-stick of the most
surpassing hideousness.

"That," I remarked, eyeing it with profound disfavour, "looks like one of
Polton's contraptions."

"It is," he replied, "if the word 'contraption' can  be accepted as the
proper designation of an extremely efficient and ingenious optical
instrument. He made it many years ago; but an instrument of virtually
identical construction was produced during the war under the name of
'trench periscope.' It is really a modern version of the ancient device
of parallel inclined mirrors, which you may see in any old book on
physics; only the mirrors are replaced by total-reflection prisms."

"Have you ever used it before?" I asked.

"Yes, on one or two occasions, and found it to answer its purpose
perfectly. I have brought it to-day  on the chance that we may find some
chink or hole through which we can poke it to get a view of the inside I
of the gallery."

"You won't get it through that keyhole that Woodburn spoke of, large as
it is," said I.

"No," he agreed. "But, as to that, we are not at the end of our
resources--or rather Polton's. He has devised an instrument for the
express purpose of looking through awkwardly placed keyholes. I have it
in my case."



He lifted the case down, and, having opened it, produced from it a small
cylindrical wooden case with a screw cap. The latter being removed, he
was able to draw out what looked like a brass pencil holder.

"This," he explained, "is a little Galilean telescope magnifying about
one and a half diameters. In front of the object glass is fixed a small,
oblong mirror, which is pivoted so that it can be set at any angle by
turning this milled ring at the eyepiece end. Of course, it has to be
parallel to the tube when the instrument is passed into the keyhole." He
handed it to me, and I put it to my eye, after setting the mirror at a
suitable angle.

"It doesn't seem a very efficient affair," I remarked, "it has such a
wretchedly small field."

"Yes," he admitted, "that is the trouble with keyholes. But this is only
an experimental form. If it seems suitable in principle, we can easily
devise something more efficient. What we have to ascertain first of all
is whether we can see through the keyhole at all. Looking at the plan,
there seems to be nothing structural in the way; but there may be some
piece of furniture that will cut off the view of the room. If there is,
the keyhole will be of no use to us."

I handed the little toy back to him with a shade of impatience. "But
why," I asked, "all this fuss? Why go about a perfectly simple inquiry in
this complicated, roundabout way? If there is good reason to believe
that someone has entered the room, why not just walk in and investigate
in a reasonable, straightforward manner? It seems to me that you and
Brodribb are standing on rather pedantic legal scruples."

He shook his head.

"I don't think so, Jervis," said he. "When you get clear instructions,
you ought to assume that the instructor means what he says. But there
is another matter, which I could only hint at to Woodburn. This man,
Toke, is extraordinarily secretive. He has not only fastened up
every opening with locks and bolts and screws, and put seals on the
fastenings, but he has forbidden his solicitor, in the most emphatic
way, to enter those rooms. Now, seals furnish no security against
burglars. Their security is against his own trusted man of business.
You or I or any reasonable person would have left the seal with
Woodburn and asked him to inspect the place from time to time to see
that all was well. Why has he shut out Woodburn in this secretive
fashion? We must assume that he has his reasons. But what can they be?
It may be mere crankiness, or it may not. Mr. Toke may be, and probably
is, a most respectable gentleman. But supposing he is not? Supposing
that his activities as a dealer in works of art cover some other
activities of a less reputable kind? And supposing that the products
of those other activities should happen to be hidden in those sealed
rooms? It is not impossible.

"But if Woodburn--or we, as his agents--should enter in the face of
explicit instructions to the contrary, and discover something illicit,
the position would be extremely awkward. Professional secrecy does not
cover that kind of thing."

"Still," I objected, "you are prepared to enter if you find evidence that
someone else has."

"Certainly," he replied. "We should have to enter or inform the police.
But we should then have no choice, whereas we have at present. And that
raises another question. If we break in and find traces of unlawful
visitors, we shall probably spoil our chances of making a capture. We are
not ready now, and our entry would almost certainly leave some traces
that would warn them not to reappear. Whereas, if we should discover
evidences of visitors before we make our own entry, we should be able to
make arrangements to catch them when they make their next visit."

I agreed without much enthusiasm, for it seemed to me that Thorndyke was
taking a mere rumour much more seriously than the circumstances
justified. In fact, I ventured a hint to that effect.

"That is quite true, Jervis," he admitted. "It is a mere report, at
present. Yet I shall be a little surprised if we find a mare's nest.
There is something distinctly abnormal about the whole affair. But we
shall be better able to judge when we have got a statement from the
servants."

"We have heard what they have to say," I replied, still extremely
sceptical of the whole affair. "But, possibly, cross-examination may
elicit something more definite. As you say, we shall see."

With this the discussion dropped, and we smoked our pipes in silence as
we watched, from the window, the gradual transition from the grey and
rather dreary suburbs to the fresh green of the country. At Hartsden
Junction, Mr. Woodburn was waiting on the platform, looking more like a
smart livery stable keeper than a lawyer, and evidently keenly interested
in our arrival.

"I am glad to see you," he said, as we walked out to the approach, "for,
the more I think about this affair, the more do I suspect that there is
something amiss. And I have been reflecting on what you said about the
seals. I had no idea that it was possible to forge a seal."

"I don't think," said Thorndyke, "that you need attach much weight to the
forgery question. It is merely a possibility that has to be borne in
mind. In the present case, it is highly improbable, as an intruder would
have to pass through the house to reach the sealed door."

"Still," objected Mr. Woodburn, "that door seems to be the only way in.
Otherwise, why should Mr. Toke have sealed it?"

There was a fairly obvious reply to this, but Thorndyke made no
rejoinder; and by this time we had reached the car, into which Mr.
Woodburn ushered us and then took his place at the steering-wheel,
looking as unsuitable for his post as if he had been at the tiller of a
fishing smack.

As the car was of the saloon type, we saw little of our surroundings and
nothing of the house until, entering through an open gate, we passed up a
shady drive and stopped opposite a handsome stone porch. The door stood
open and framed the figure of a pleasant-looking middle-aged woman.

"This," said Mr. Woodburn, introducing us, "is Mr. Toke's housekeeper,
Mrs. Gibbins. I have told her about you, and she is as much interested in
you as I am."

Mrs. Gibbins confirmed this by a smile and a curtsy. "I am sure,
gentlemen," said she, "we shall all be very grateful to you if you can
find out what these mysterious sounds are, and put a stop to them. It
is very uncomfortable to feel that strangers--and dishonest strangers,
too--are creeping about the house in the dead of the night."

"It must be," Thorndyke agreed, warmly. "But, before we start to find out
what those sounds are, we want to be quite sure that they really exist."

"There is no doubt about their existing," Mrs. Gibbins rejoined, with
intense conviction. "We have all heard them. And they certainly come from
the gallery wing, for my nephew, Edward, got out of bed on two occasions
and went part of the way down the corridor and listened; and he was quite
sure that the sounds came from the gallery or the rooms that open out of
it. And it wasn't rats. Everybody knows the kind of sound that rats make,
scampering about an empty room. It wasn't like that, at all. It was like
someone moving about quietly and, now and again, moving things. But there
is another thing that can't be explained away. This house is supplied
with water from an Artesian well. The water is pumped up by a windmill
into a tank, which is on the level of the top floor, and it runs from the
tank into the pipes that supply the house. The tank being so high up, the
pressure of the water is quite considerable, and whenever a tap is
running in any part of the house, you can hear a distinct hum in the main
pipe. Of course, you can hear it much more distinctly at night when every
thing else is quiet.

"Now, I am a rather light sleeper, especially towards morning, and, on
several occasions--over and over again--I have heard the water humming
in the pipe when all the household were in bed and asleep. And always
about the same time--just before it begins to get light."

"That is very remarkable, Mrs. Gibbins," said Woodburn. "You did not tell
me about the water. It is a most striking fact. Don't you think so,
Doctor?"

"I do," replied Thorndyke, "especially when taken with the other sounds.
I take it, Mrs. Gibbins, that there is water laid on in the gallery
wing?"

"Yes, sir. There is a lavatory with a fixed basin and a cold-water tap
over it, and there is also a peculiar sort of sink--Mr. Toke calls it a
chemical sink, I believe--in the work-room."

"And you say that the sound of running water occurs always at the same
time? Do you never hear it at other times?"

"Oh, yes," she replied, "we hear it occasionally at other times. Not very
often, though. But it seems to occur always when we have heard the other
sounds.  It is just as if the person had been doing some job and had a
wash before he went away."

Mr. Woodburn laughed cheerfully.

"Tidy fellow, this," said he. "I wonder what he does in there. It's a
quaint situation. He'll be ringing for his breakfast next."

"Can you form any idea," Thorndyke asked, "how often these sounds occur?"

"I should say," replied Mrs. Gibbins, "that they happen pretty regularly
twice a week--generally on Wednesdays and Fridays."

Mr. Woodburn laughed heartily. Thorndyke's appearance on the scene had
evidently acted favourably on his spirits.

"Quite a methodical chap," he chuckled. "Keeps regular hours, and has a
wash and brush up before he goes home."

"We mustn't take him too much for granted," Thorndyke reminded him. "We
have got to establish his existence as a matter of undoubted fact, though
I must admit that Mrs. Gibbins's account is extremely circumstantial and
convincing. It establishes a case for a very thorough investigation and I
think we had better begin by having a look at the door of the gallery.
What will be about the height of that keyhole that you spoke of?"

Mr. Woodburn indicated the height by reference to a point on his own
waistcoat. "But I am afraid the keyhole won't help you much," he added.
"As I think I told you, I couldn't see anything through it, excepting a
patch of the opposite wall."

"Perhaps we can manage to get a better view," said Thorndyke; "that is,
if there is nothing in the way. Probably, Mrs. Gibbins can tell us about
that. How was the furniture arranged when you were in there last?"

"There is very little furniture in there, at all," the housekeeper
replied, "unless you call the wall-cases furniture. There is a large
table across the end of the room, and there are three chairs, one
arm-chair and two ordinary dining-room chairs. The arm-chair is behind
the table, nearly in the middle, and the other two are at the ends of the
table."

"You say they 'are'," Thorndyke remarked. "Do you mean that that is how
they were placed when you were last in the room?"

"Yes, sir. But I think they must be like that still, because the last
time I was in there was on the day when Mr. Toke went away. I helped him
to shut up the room and seal the door. They couldn't very well have been
moved after that."

"Apparently not," Thorndyke admitted. "Then, in that case, we may as well
go and have a look at the door and see if it is possible to get a glimpse
of the inside of the room. And perhaps we had better take a chair with
us, as the keyhole is at a rather inconvenient height."

Mr. Woodburn picked up a chair and led the way out of the morning room in
which we had been holding our conversation, across the hall and into a
narrow passage, which became almost dark as a sharp turn cut off the
light from the doorway by which we had entered.

"Queer old place," he remarked as the corridor took another turn. "All
holes and corners. I am wondering how you are going to see into that
room. I couldn't; but I suppose a man who can produce another man's seal
out of a top hat won't make any difficulty about seeing round a corner."

"We have only undertaken to try," Thorndyke reminded him. "Don't let us
take credit prematurely."

The disclaimer was not entirely unnecessary; for, when the corridor took
yet another abrupt turn and brought us to a blind end in which was a
massive door it became clear to me, from the manner both of Mrs Gibbins
and Mr. Woodburn, that there was an expectation of some sort of display
of occult powers on Thorndyke's part. So much so that, for the first
time, I felt quite grateful to Polton.

"There you are," said Mr. Woodburn, placing the chair in position, and
standing back expectantly to watch the proceedings, as if he had some
hopes of seeing Thorndyke put his head through the keyhole, "Let us see
how you do it."

My colleague seated himself with a deprecating smile, and, laying the
research case on the floor, unfastened the catch and raised the lid;
whereupon Mr. Woodburn and Mrs. Gibbins craned forward to peer in, Having
taken a preliminary peep through the keyhole, Thorndyke produced the
little wooden case and drew out Polton's diminutive spy-glass, which he
inserted easily enough into the roomy opening. As he applied his eye to
the tiny eyepiece and turned the milled ring to adjust the mirror, the
two observers watched him with bated breath; as, indeed, did I, and with
no small anxiety. For, apart from the importance of the result, a
complete failure would have been a shocking anticlimax. Great, therefore,
was my relief when Thorndyke announced:

"Well, at any rate, there is no obstruction to the view, such as it is.
But it is not easy to make out the arrangement and relative positions of
things with such a very restricted field of vision. However, as far as I
can see, there are no signs of any appreciable disturbance. I can see the
wall-cases at the end of the room, and their shelves are filled with what
look like Bow and Chelsea figures. So there has been no robbery there.
The cases at the sides of the room are not so easy to see, but I think I
can make out the contents, and they appear to contain their full
complement. Evidently, so far as the collection is concerned, there has
been no robbery on any considerable scale.

"Then the position of the furniture corresponds generally with Mrs.
Gibbins's description. There is an arm-chair behind the table and an
ordinary dining-chair at each end. I can also see what looks like a
shallow box or case of some kind on the table."

"A box on the table?" exclaimed Mrs. Gibbins. "That is curious. I don't
remember any box, or anything else, on the table."

"Perhaps Mr. Toke put it there after you left," suggested Mr. Woodburn.

"But he couldn't," Mrs. Gibbins objected. "I went out with him and helped
him to seal up the door. He couldn't have gone back after that."

"No. That is obvious," Woodburn admitted. "So it looks as if someone had
been in the room, after all."

"Do you say, positively, Mrs. Gibbins, that there was nothing on the
table when you left the room with Mr. Toke?" Thorndyke asked.

"Well, sir," the housekeeper replied, "one doesn't like to be too
positive, but I certainly thought that there was nothing on the table. In
fact, I feel sure that there wasn't."

"That seems pretty conclusive," said Woodburn. "What do you think,
Doctor?"

"It is conclusive enough to us," Thorndyke replied, diplomatically. "But,
as a lawyer, you will realize the difficulty of coming to a definite
decision on negative evidence. To justify you in acting in direct
opposition to your client's instructions, you ought to have undeniable
positive evidence. We are not considering our own beliefs, but the legal
position."

"Yes, that is true," Mr. Woodburn conceded, evidently interpreting
Thorndyke's polite hint that ladies are sometimes apt to confuse the
subjective with the objective aspects of certainty.

"Do you see any thing else?"

"No. I think that is the sum of my observations, But remember that the
room is strange to me. Perhaps if you, who know the room, were to take a
look through the instrument, you might detect some change that would not
be apparent to me."

To say that Woodburn jumped at the offer would be to understate the
case. In his eagerness to occupy the seat of observation, he nearly sat
on Thorndyke's lap. But, apparently, Polton's "contraption" did not come
up to his expectations, for, after peering in at the eyepiece for some
seconds, he said in a tone of slight disappointment:

"I don't seem to make much of it. I can only see a tiny bit at a time,
and everything looks in its wrong place. The table seems to be right
opposite this door instead of where I know it to be."

"You must disregard the positions of things," Thorndyke explained.
"Remember that you are looking into a mirror."

"Oh, I hadn't realized that," said Woodburn, hastily. "Of course, that
explains the odd appearance of the room." He reapplied his eye to the
instrument, and now was able to manage it better, for he presently
reported:

"I think the cases look all right and everything else appears as usual.
As to that box, of course, I can say nothing. I have never seen it
before, and I can't quite make out what sort of box it is. It looks like
metal."

 "That was what I thought," said Thorndyke. "Perhaps Mrs. Gibbins may
recognize it." The suggestion was evidently acceptable, for the
housekeeper "outed" Mr. Woodburn with great promptness, and, having
seated herself, applied her eye to the instrument. But she was even less
successful than her predecessor, for, after a prolonged stare through
the eyepiece, she announced that she could see nothing but the carpet,
which appeared, unreasonably, to have affixed itself to the opposite
wall. However, Thorndyke came to her aid, and eventually enabled her to
see the mysterious box on the table; concerning which she again asserted
with deep conviction that, not only was she quite sure that it had not
been there when she and Mr. Toke had vacated the room, but that she was
equally certain that she had never seen the box before at all.

When she had finished her observations (which seemed to concern
themselves principally with the floor and the ceiling), I came into the
reversion of the chair, by way, ostensibly, of confirming the previous
observations. And, when I came to look through the little instrument in
the conditions for which it was designed, I was disposed to be apologetic
to Polton. The field of view was, indeed, extremely small, but the little
circular picture at which one looked was beautifully clear and bright;
and the fine adjustment for moving the mirror enabled one to shift the
field of vision gradually and preserve a continuity in the things seen
that had, to some extent, the effect of a larger field.

"Well," said Woodburn, as I rose from the chair, "what have we arrived
at? Or haven't we arrived at any conclusion?"

"I think," said Thorndyke, "that we must conclude that our observations
tend to confirm the suspicion that someone had obtained access to this
room. But I do not think that we have enough evidence to justify us in
disregarding Mr. Toke's very definite instructions."

"Then," said Woodburn, "what do you suggest that we ought to do?"

"I suggest that we make a careful survey of the house to see if we can
find any means of access to this room that the seals do not cover; and
if, as I expect, we fail to find any such means, then we must make some
more exact and continuous observations from this door."

"You don't suggest that we post someone at this keyhole to keep watch
continuously, do you?" exclaimed Woodburn.

"No," replied Thorndyke. "That would be impracticable. But I think we
could achieve the same result in another way. At any rate, I will take
the preliminary measures before we go away from here, in case they may be
needed."

He withdrew the "spy-glass" from the keyhole, and, having put it away in
the research case, produced from the latter a small cardboard box which,
when the lid was removed, was seen to contain a number of little
cylinders of hardwood about six inches long and of varying diameters,
from a quarter of an inch up to five-eighths.

"These," he explained, "are gauges that my assistant has made to obtain
the exact dimensions of the keyhole, so that he can make a more efficient
instrument."

"The instrument that you have got is efficient enough," said Woodburn.
"The trouble will be to get someone to stay here to use it."

"Perhaps we can produce an instrument that will do its work without an
attendant," replied Thorndyke. "But we will talk about that when we have
made our survey. Now, I will just take these measurements."

He seated himself once more and proceeded to pass the larger cylinders
one by one through the keyhole. All of them passed through fairly easily
excepting the two largest, which were returned to the box.

"The internal diameter of the keyhole," said Thorndyke, "is nearly
nine-sixteenths of an inch. Probably it has been a little enlarged by
wear, but even so the key must have been an out-size. I shall call it
half an inch."

He marked, with a pencil, the approved cylinder, and, having returned it
to the box, announced that he was ready to proceed to the next item in
the programme.

"Perhaps," he suggested, "we had better take a glance at the lofts which
are over the gallery."

Mr. Woodburn looked interrogatively at the housekeeper, who volunteered
the information that the entrance to them was at the top of the back
staircase, and that the key was on her bunch.

"The entrance to the lofts is not sealed, then?" Thorndyke remarked.

"Apparently not," said Woodburn; "which suggests that we are not likely
to find anything of interest in them. Still, we may as well have a look
at them and satisfy ourselves."

We followed the housekeeper through a surprising labyrinth of passages
and rooms, which seemed to be on all sorts of levels, with steps up and
down, which made it necessary to approach all doors with caution to avoid
being tripped up or stepping into empty air. Eventually, we came to an
unlocked door which gave entrance to the back staircase, up which Mrs.
Gibbins preceded us in a dim twilight. At each landing, open doors gave
glimpses into dark and mysterious corridors which apparently burrowed
among the bedrooms, and the top landing showed us, in addition, a locked
door with an enormous keyhole, into which the housekeeper inserted a
ponderous key. The door creaked open, and revealed a flight of narrow,
ladder-like stairs, up which we crawled painfully and cautiously,
Thorndyke bringing up the rear, encumbered with his research case and the
Poltonic walking-stick.

There was no door at the top of the stairs (which seemed a lost
opportunity on the part of the architect), and only a pretence of
a landing outside the narrow doorway which gave entrance to the
lofts. Here we stood for a few moments, looking into the long range
of well-lighted lofts that stretched away on either side. There was
something a little weird and impressive in the aspect of those great,
wide attics with their rough oaken floors, littered with the cast-off
household gods of forgotten generations, stretching away into the
distance among the massive and almost unhewn timber of the great
roof. Each of the two ranges--for we stood at the angle of the body
and the wing of the house--was lighted by a pair of dormer windows on
each side, filled with little panes of greenish glass set in leaded
casements, so that we were able to see the whole extent with the
exception of a few dark corners at the extreme ends.

"Well," said Woodburn, looking a little distastefully at the littered
floor, covered, as it seemed, with the dust of centuries, "is it worth
while to go in? Looks a bit dusty," he added, with a glance at his
brilliantly polished boots.

"I think I will just walk down the lofts," said Thorndyke, "as a matter
of form, though it is pretty clear that there have been no recent
visitors. But there is no need for you to come."

That it was but a mere formality became evident as soon as we had
started; for, glancing back, I could see that we had left plain and
conspicuous footprints in the impalpable dust that lay in an even coating
on the bumpy floor. Evidently, we were the first visitors who had trodden
that floor for, at least, some years.

"Still," said Thorndyke, when I made a remark to this effect, "we had to
establish the fact. If there is some secret way into the gallery, our
only chance of discovering it will be by excluding, one by one, all the
places in which it is not to be found. This is evidently one of them."

"Well," said Woodburn, as we emerged; "we can write off the lofts, I
think. Dust has its uses, after all. What are we going to explore next?"

"I suppose," Thorndyke replied, "we had better examine the outside of the
premises."

"Yes," Woodburn agreed, "that seems to be the reasonable thing to do,
seeing that, if there have been any visitors, that is where they must
have come from. But there is mighty little to see. I can tell you that
much, for I have made a thorough inspection, myself."

Mr. Woodburn was right. There was very little indeed to see. The gallery
stood above a range of what were now cellars, but had formerly been
rooms, as we gathered from the windows, some entirely bricked up, while
others were reduced to small openings, glazed with ground glass and
protected by stout iron bars. The only approach to them was from within
the house, by a massive door at the bottom of a flight of stone steps;
and that door was not only sealed, but also secured by a heavy padlock of
the Yale type, of which the minute key-slit was covered by a sealed
label.

From outside the house, there was no entrance of any kind to the
gallery wing. The windows of the gallery, itself, looked on the garden
at the back of the house; but an inspection of them by means of the
ladder, which had been put there for our convenience, only served to
confirm Woodburn's account of them. They were obviously untouched; and
the lace curtains on the inside made it impossible to get the faintest
glimpse into the room. The windows of the rooms which communicated
with the gallery were equally impossible as a means of access. We
examined them with the aid of the ladder from the narrow strip of
garden that separated the side of the wing from the high wall that
enclosed the whole domain. They, also, were evidently intact, and were
guarded internally by massive shutters that effectually excluded the
possibility of seeing in.

"That seems to be the lot," said Woodburn, as we put the ladder back
where we had found it, "unless there is anything else that you would like
to see."

Thorndyke looked up at the house, inquisitively, and then glanced along
the wall down the garden. "I think," said he, "I understood you to say
that there was a churchyard on the other side of that wall."

"Yes. Do you want to see it? I don't know why you should."

"We may as well take a look at it," was the reply. "Any visitors,
entering the house at night, would probably come over that wall rather
than through the front grounds, particularly if there is a churchyard to
take off from. A country churchyard is pretty secluded at night. It would
even be possible to use a portable ladder."

"So it would," agreed Woodburn. "And this is a disused churchyard. They
have built a new church at the other end of the village, the Lord knows
why. They had better have restored the old church. But any visitors to
the old churchyard would have the place to themselves at night."

"Then let us go and inspect it," said Thorndyke. "If there have been
repeated visits, there ought to be some traces of the visitors."

We went back through the house and out by way of the drive and the front
gate. Turning to the right, we walked along the front of the Manor House
grounds to the end of the enclosing wall where it was joined by the lower
wall of the churchyard. Presently, we came to a dilapidated wooden gate
which yawned wide open on its rickety hinges. Passing in through this, we
took our way along an overgrown path, past a tall headstone and a decayed
altar tomb, enclosed by rusty, ivy-grown railings. In front of us, a
great yew tree cast a deep shadow across the path; and beyond, a
smallish, ancient-looking church, with gaping windows from which the
tracery had disappeared, huddled under a dense mantle of ivy, looking the
very picture of desolation and decay. As we walked, Thorndyke looked
about him critically, keeping an attentive eye on the ground beside the
path, the high, neglected grass which everywhere sprang up between the
graves being obviously favourable to a search for "traces."

So we advanced until we entered the gloomy shadow of the great yew tree.
Here Thorndyke halted to look about him. "Somewhere in this
neighbourhood," said he, "would be the most probable place for a
nocturnal operator to make his arrangements. That is the Manor wall in
front of us. I can see the roof of the gallery wing through the trees.
That big sarcophagus tomb will be nearly opposite the end of the wing."

"Yes," I said. "It seems to mark the position that would be most
convenient for negotiating the wall; and if you notice the grass, there
seems to be a faint, rather wide track, as if it had been walked over by
someone who had been careful not to tread it down all in one place."

"I think you are right," said Woodburn. "Now you mention it, I think I
can make out the track quite plainly. It seems to lead towards that
tomb."

"The grass has certainly been walked over," Thorndyke agreed, "and I see
no signs of its having been trodden anywhere else. But don't let us
confuse matters by walking over it ourselves. Let us strike across the
graves and approach along the wall."

We followed this course, keeping close to the wall as we approached the
great tomb. The latter stood about ten feet from the wall, and, as we
drew near, I was surprised to notice that the grass between the tomb and
the wall appeared quite untrodden.

Thorndyke had also noticed this rather unexpected circumstance, and, when
we were within a yard or two of the tomb, he halted and looked curiously
along the ground at the foot of the wall.

"There is certainly no sign of the use of any ladder," he remarked. "In
fact, there is no indication of any one having approached close to the
wall. The track, if it really is one, doesn't appear to go beyond the
tomb."

"That is what it looks like to me," agreed Woodburn, "though I am hanged
if I can see any reason why it should. They couldn't have jumped from the
top of the tomb over the wall."

"It looks," I suggested, "as if this place had been used rather as a post
of observation, or a lurking-place where the sportsman could keep out of
sight until the coast was clear." We approached the tomb from the
direction of the wall and sauntered round it, idly reading the
inscriptions, which recorded briefly the life-histories of a whole
dynasty of Greenlees, "late of Hartsden Manor in this Parish," beginning
with one John Greenlees who died in 1611. At length he turned away and
began to retrace his steps down the path towards the gate.

"They were a turbulent family, these Greenlees," said Woodburn. "Always
in hot water. Bigoted Papists in early days, and, of course, Jacobites
after the Revolution. From what I have heard, Hartsden Manor House must
have seen some stirring times."

While he was speaking, I was glancing through the inscriptions on the
back of the tomb. Happening to look down, I noticed a match in the grass
at my feet, and stooped to pick it up. As I did so, I observed another;
on which I made a search and ultimately salved no less than six.

"What have you found, Jervis?" Thorndyke asked, as I rose.

I held out my hand with the six matches in it. "All from the same place
at the back of the tomb," said I. "What do you make of that?"

"It might mean five failures on a windy day or night," he replied, "or
six separate cigarettes; and the operator may have come here to get a
'lee side,' or he may have got behind the tomb so that the light should
not be seen from the road. But we must not let our imaginations run away
with us. There is nothing to show that the person or persons who came to
this tomb have any connection with our problem. We are looking for some
means of access to the gallery, and, up to the present, we have not found
any. The fact, if it were one, that some persons had been lurking about
here, waiting for a chance to enter, wouldn't help us. It would not tell
us how they got in; which is what we want to know."

Nevertheless, he continued, for some time, to browse round the tomb,
dividing his attention between the inscriptions and the grass that
bordered the low plinth.

"Well," said Woodburn, "we seem to have exhausted the possibilities,
unless there is anything else that you want to see."

"No," replied Thorndyke, "I don't think it is of any use to prolong our
search. I suspect that there is some way into the house; but, if there
is, it is too well hidden to be discoverable without some guiding hint,
which we haven't got. So the answer to our first question is negative,
and we must concentrate on the second--does anyone, in fact, effect an
entrance to the gallery?"

"And how do you propose to solve that problem?" enquired Woodburn.

"I propose to install an automatic recorder which will give us a series
of photographs of the interior of the room."

"And catch 'em on the hop, eh?" said Woodburn. "But it doesn't seem
possible. Why, you would have to take a photograph every few minutes; and
then you wouldn't bring it off, because the beggars seem to come only at
night."

"I am not expecting to get photographs of the visitors themselves,"
Thorndyke explained. "My idea is that, if any persons do frequent those
rooms, they will almost certainly leave some traces of their visits. Even
the moving of a chair would be conclusive evidence, if it could be
proved, as it could be by the comparison of two photographs which showed
it in different positions. I shall send my assistant, Mr. Polton, down to
set up the apparatus, and perhaps you will give Mrs. Gibbins instructions
to give him all necessary facilities, including the means of locking up
the corridor when he has fixed the apparatus and set it going."

To this Mr. Woodburn agreed, gleefully, and, as a train was due in a
quarter of an hour, we embarked in his car without re-entering the house.

Chapter XII: The Unknown Coiner

FROM Charing Cross we walked home to the Temple, entering it by way of
Pump Court and the Cloisters. As we were about to cross King's Bench
Walk, I glanced up at the laboratory window, and caught a momentary
glimpse of Polton's head, which, however, vanished even as I looked; and,
when we arrived at our landing, the door of our chambers was open, and he
was visible within, making a hypocritical pretence of laying the
dinner-table, which had obviously been laid hours previously. But his
pretended occupation did not conceal the fact that he was in a twitter of
anxiety and impatience, which Thorndyke proceeded at once humanely to
allay.

"It had to be a cold dinner, as I didn't know what time you would be
home," Polton explained; but Thorndyke cut short his explanations and
came to the essential matter.

"Never mind the dinner, Polton," said he. "The important point is that
your automatic watcher will be wanted, and as soon as you can get it
ready."

Polton beamed delightedly on his employer as he replied:

"It is ready now, sir, all except the objective. You see, the clock and
the camera were really made already. They only wanted a little
adaptation. And I have made an experimental objective, and done some
trial exposures with it. So I am ready to go ahead as soon as I have the
dimensions of the keyhole."

"I can give you those at once," said Thorndyke, opening the research case
and taking out the wooden cylinders. "The keyhole will take a half-inch
tube fairly easily."

Polton slapped his thigh joyfully. "There's a stroke of luck!" he
exclaimed. "You said it would be about half an inch, so I used a
half-inch tube for my experimental objective. But I never dared to hope
that it would be the exact size. As it is, all I have got to do is to fix
it on to the camera. I can do that tonight and give it a final trial.
Then it will be ready to set up in place to-morrow. Perhaps, sir, you
will come up presently and see if you think it will do. I shall have got
it fixed by the time you have finished dinner."

With this, having taken a last glance at the table, he retired in
triumph, with the box of cylinders in his hand.

"What is this 'automatic watcher'?" I asked, as we sat down to our meal.
"I assume that it is some sort of automatic camera. But what is its
special peculiarity?"

"In its original form," replied Thorndyke, "it consisted of a clock of
the kind known as an English Dial, with a magazine camera fixed inside
it. There was a simplified striking movement which released the shutter
at any intervals previously arranged. It also had an arrangement for
recording the time at which each exposure was made. It was quite a
valuable appliance for keeping a watch on any particular place. It could
be set up, for instance, opposite the door of a strong room or in any
similar position."

"But suppose the thief made his visit in the interval between two
exposures?"

"That was provided for by a special attachment whereby the opening of the
door was made to break an electric circuit and release the shutter. So
that whenever the door was opened an exposure was made and the time
recorded. But, for our present purpose, although we have retained the
principle, we have had to modify the details considerably. For instance,
we have separated the clock from the camera, so that it can be fixed far
enough away from the door to prevent its tick from being heard in the
gallery. The releasing mechanism of the clock is connected with an
electromagnet in the camera which actuates the shutter and the film
roller. The lens is in a tube five inches long, with a reflecting prism
at the farther end, which will, of course, be passed through the keyhole,
and the camera screwed on to the door. That is a rough sketch of the
apparatus. You will see the details of it when we go up to make our
inspection."

"And how often do you propose to make an exposure?" I asked.

"One exposure every twenty-four hours would do for us," he replied, "as
we merely want a daily record of the positions of the various objects in
the room. But that does not satisfy Polton. He would like an exposure
every hour. So we have arrived at a compromise. There will be an exposure
every six hours. Of course, those made at night will show nothing, and
both of those made in daylight, when the room will be unoccupied, will,
presumably, be alike. But I can see that Polton will not be happy if
there is not a good string of exposures."

"Supposing the exposures are all alike?" I suggested.

Thorndyke laughed grimly. "Don't be a wet blanket, Jervis," said he. "But
I must admit that it would be something of an anticlimax and distinctly
disappointing, though not entirely unexpected. For, if there are really
visitors, it is quite possible that they do not go to the gallery at all.
Their business, what ever it may be, is, quite conceivably, carried on in
one of the rooms that open out of the gallery. So a negative result with
the camera would not prove that no one had entered the gallery wing."

It was my turn to smile, and I did so. "It is my belief, Thorndyke," said
I, "that you don't mean anything to disprove it. You are not approaching
the investigation with an open mind."

"Not very open," he admitted. "The housekeeper's statement, together with
all the other circumstances of the case, make a very strong suggestion
of something abnormal, so strong that, as you say, I am not prepared to
be easily satisfied with a negative result. And now, if we have finished,
we had better go up to the laboratory and have a look at Polton's
masterpiece."

We rose, and were just moving towards the door when a firm tread became
audible on the landing, and was followed by a familiar knock on the brass
knocker of the inner door.

"Miller, by Jove!" I exclaimed. "How unfortunate! But I can entertain him
while you go up to Polton."

"Let us hear what he has to say, first," replied Thorndyke; and he
proceeded to throw open the door.

As the Superintendent entered, I was impressed by a certain curious
mixture of jauntiness and anxiety in his manner. But the former
predominated, especially as he made his triumphant announcement.

"Well, gentlemen, I thought you would be interested to hear that we have
got our man."

"Dobey?" asked Thorndyke.

"Dobey it is," replied Miller. "We've got him, we've charged him, and he
is committed for trial."


"Come and sit down," said Thorndyke, "and tell us all about it."

He deposited the Superintendent in a comfortable arm-chair, placed on the
little table at his elbow the whisky decanter, the siphon, and the box of
the specially favoured cigars, and while the tumbler was being charged
and the cigar lighted, he filled his pipe and regarded his visitor with a
slightly speculative eye.

"Where did you catch him?" he asked, when the preliminary formalities
were disposed of.

Miller removed the cigar from his mouth in order the more conveniently to
smile.

"It was a quaint affair," he chuckled. "We caught him in the act of
picking the lock of his own front door. Rum position, wasn't it? Of
course, the key was at the police station at Maidstone. We had been
keeping a watch on the flat, but it happened that day that one of our
sergeants was going there with a search warrant to have another look over
the premises in case anything should have been missed at the first
search. When he got up to the landing, there was my nabs, angling at the
keyhole with a piece of wire. He was mightily surprised when the sergeant
introduced himself, and still more so when he was told what he was
charged with."

"Was he charged with the murder or the house breaking?"

"Both. Of course, the usual caution was administered, but, Lord, you
might as well have cautioned an oyster."

"Did he say nothing at all?"

"Oh, the usual thing. Expressed astonishment--that was real enough,
beyond a doubt. Said he didn't know what we were talking about, but was
perfectly sure that he didn't want to make any statement."

"I suppose he pleaded 'not guilty' at the police court?"

"Yes. But he wouldn't say anything in his defence, excepting that he knew
nothing about the murder and had never heard of Inspector Badger, until
he had got legal advice. So the magistrate adjourned the hearing for a
couple of days, and Dobey got a lawyer to defend him--a chappie named
Morris Coleman."

"Of Kennington Lane?"

"That's the man. Solicitor and advocate. Hebrew, of course. Downy bird,
too, but quite a good lawyer."

"Yes," said Thorndyke, "I have seen him in court. A cut above the
ordinary police-court advocate. And what did he have to say?"

"Reserved his defence, of course. They always do if the case is going for
trial. That's the worst of these police-court solicitors. But it usually
means that they haven't got any defence, and of course that is what it
means now, so it doesn't matter. But it is a time-wasting plan when they
have got a defence, and the judge usually has something to say about it.
Still, you can't cure them. They think they get an advantage by springing
a defence on the court that nobody expected."

"You say you are proceeding on both the charges. Why are you bringing in
the house-breaking?"

"Well, of course," replied Miller, "it is the murder that he will
actually be tried for. But we shall have to prove the facts of the
house-breaking to explain how the stolen paper came to be found."

As he gave this explanation, the Superintendent stole a slightly furtive
glance at Thorndyke, which I understood when the latter remarked, dryly:

"True. And the evidence of the witnesses to the house-breaking may serve
to supply the deficiencies of the station-master at Strood. I take it
that they will be able to identify Dobey."

"They have. Picked him out instantly from a crowd of thirty other men.
And as to that station-master, it's just a silly excess of caution and
over-conscientiousness. He didn't look at the man particularly, and so he
won't swear to him. But, as his description of the man agrees with that
of the witnesses to the house breaking, and they are ready to swear to
Dobey, it will, as you say, help matters a bit. But, of course, the
finding of the paper in his possession is the really crucial piece of
evidence."

"It is more than that," said Thorndyke. "It is the whole of the evidence
in regard to the murder. Without it your bill would never get past the
Grand Jury. And, as to the house-breaking, as it can't be included in the
indictment, I doubt whether the court will allow any reference to it.
That, however, remains to be seen."

"Well," rejoined Miller, "it doesn't matter a great deal. The paper fixes
the crime on him."

With this, he dipped his nose into his glass and resumed his cigar with
the air of having disposed of the subject; and I took the opportunity to
raise another point.

"Did you say that Dobey was found picking his lock with a piece of wire?"
I asked.

"Yes," he answered with a chuckle. "Quaint situation, wasn't it?"

"It strikes me as more than quaint," I replied. "It is most extraordinary
that he should not have provided himself with a key of some sort."

"It is," Miller agreed. "But it was a simple latch, and I expect he was
pretty handy with the wire. And I don't suppose he often went to the
flat. Still, as you say, he must have been a fool not to get a key."

"He must," said I. "It is a striking example of the criminal mentality."

"Yes," agreed Miller, "they are not a very bright lot." He paused
reflectively for a few moments, puffing at his cigar reflectively, and
then resumed in a meditative tone: "And yet it doesn't do to rate them
too low. We say to ourselves that they are all fools. So they are, or
they wouldn't be crooks. Crime is never a really sound economic
proposition. But there is one thing that we must bear in mind: there are
two kinds of crooks--those that get caught, and those that don't. And a
crook that doesn't get caught may never come into sight at all. If he
manages well enough, his existence may never be even suspected. I have
just heard of a case in which the existence of a man of this class has
been disclosed by a mere chance. But we don't know who he is, and we are
not very likely to find out. I'll tell you about the case. It's a queer
affair.

"Just recently, one of our men who specializes in note forgeries and
knows a good deal about money of all kinds, had to spend a week or two on
the Continent. When he was about to return, he changed his foreign money
into English and got one or two sovereigns. Now, when he got home and had
a look at those sovereigns, he thought there seemed to be something queer
about one of them. So he got a chemist to weigh it, but the weight was
apparently all right--it was only an ordinary shop scale, you know, but
it weighed within a fraction of a grain. Then he measured it; but all the
dimensions seemed to be correct. But, still, to his expert eye, it didn't
look right; and it didn't sound right when he rang it. So he took it to
an assayist whom he knew, and the assayist tried its specific gravity and
tested it so far as was possible without damaging the coin, and he
reported that it was undoubtedly gold of about the correct fineness. But
still our man wasn't satisfied. So he took it to the Mint, and showed it
to one of the chief officials. And then the murder was out. It wasn't a
milled coin at all. It was a casting. An uncommonly good casting and very
neatly finished off at the edge, but an undoubted casting to the skilled
eye. So they passed it on to the assay department and made a regular
assay of it. The result was very quaint. It was gold right enough, and
just about 22 carat; but it was not exactly the composition of a
sovereign. There was a slight difference in the alloy. That was all.
There was no fraud. The proper amount of gold was there. Yet it was a
counterfeit coin. Now, what do you make of that?"

"Nothing," I answered, "unless it was a practical joke."

"Well, it wasn't. The Mint people asked us to look into the matter, and
we did. The result was that we found one or two more specimens of this
queer, unofficial money--you couldn't call it base coin--in France,
Belgium, and Holland. Evidently, there is a regular manufacture."

"But what on earth can be the meaning of it?" I demanded.

Miller chuckled. "We can only guess," said he, "but we can take it that
the sportsman who makes those sovereigns doesn't do it for fun. And, if
he makes a profit on them, he doesn't buy his gold from the bullion
dealers, and he doesn't pay the market price for it. On the other hand,
he probably sells it for export at considerably above its nominal value,
now that gold is so difficult to get. So, if he steals his gold, or gets
it cheap from the thieves, and sells it at a premium, he doesn't do so
badly. And he will be mighty hard to catch. For the coins are genuine
golden sovereigns, and only a fairly expert person would be able to spot
them. And experts are pretty rare, nowadays. Once, every little
shopkeeper was an expert; but now there are plenty of people who have
never seen a sovereign."

"It is a clever dodge," I remarked, "if the gold is really stolen."

"Clever!" repeated Miller, enthusiastically. "It's a stroke of genius.
You see, it avoids all the crook's ordinary difficulties. He can get rid
of the stones pretty easily, as they can't be identified separately. But
the gold is less easy to dispose of at a decent price. For, if a bullion
dealer is willing to buy it--which he probably isn't, if he is a
respectable man--the transaction is known, and the vendor has left
dangerous tracks; and the ordinary fence will only give a knock down
price. He must make a big profit to set off the risk that he takes.

"But there is another case that has just come to light--probably the
same man. You know that, for some time past, the Mint has been calling in
all real silver money. Now, since this sovereign incident, it occurred to
the people there to look over the silver coins that came in; and, at the
first cast, they came on a half-crown that turned out to be a casting.
But it was silver. Further search brought one or two more to light.
Someone was making silver half-crowns.

"Now, here was a paradoxical situation! The coiner was making good silver
coin while the Mint was issuing base money. Of course, coining is
illegal. But this coiner could not be charged with uttering base coin. It
would be hard to prove to a jury that it was counterfeit.

"Here you see the difference between the stupid crook and the clever
crook. The fool tries to grab the whole--and doesn't do it. He makes his
coin of pewter and probably steals that. They generally used to. If he
got half a crown for his pewter snide, it would be all profit. But he
doesn't, because it is a duffer. So he has to sell it cheap to the snide
man. And he gets caught. But this sportsman puts, say, a shilling's worth
of silver into his half-crown, and he doesn't have to pay the snide man.
He can pass it quite safely himself. And he doesn't get caught."

"He runs the risk of getting caught if he passes it himself," I objected.

"Not at all," said Miller. "How should he? What you're overlooking is
that the coins are good coins. They pass freely, and they will bear
assay. Only an expert can spot them, and then only after close
examination. But he must make a big profit. He could easily get rid of a
hundred a day. There's seven pounds ten shillings profit, even if he buys
the silver at the market price, which he probably does not. That silver
is most likely burglars' loot--silver tea-pots and candlesticks melted
down; stuff that he would have to sell to a fence at about the price of
brass. I tell you, Dr. Jervis, that coiner is a brainy customer. He'll
want a lot of salt sprinkled on his tail before he'll get caught."

"I think you are rather over-estimating his profits," said I. "He has not
only to pass the coins; he has got to make them. Good workmanship like
that means time and labour. And there is the gold. Most trade jewellery
is made of a lower-grade gold than 22 carat. He would either have to buy
fine gold from the bullion dealers to bring his low-grade gold up to
standard or to do a good deal of conversion himself."

While Miller was considering this difficulty, the door opened, and
Polton's head became visible, his eyes riveted on the Superintendent's
back with an expression of consternation. I think he would have withdrawn,
but that Miller, in some occult manner, became aware of his
presence and addressed him.

"Good evening, Mr. Polton. We were just discussing a little problem that
is rather in your line. Perhaps you would give us your opinion on it."

On this, Polton advanced with a slightly suspicious eye on the
Superintendent, and Miller proceeded to put his case.

"The problem is, how to make sovereigns--castings, you know--out of
jewellery composed of low-grade gold. Supposing you had got a lot of
rings, for instance, of 18-carat gold. Now, how would you go about
turning them into 22-carat sovereigns?"

Polton crinkled at him reproachfully.

"I am surprised at you, Mr. Miller--an officer of the law, too--suggesting
such a thing. Of course, I wouldn't do anything of the sort."

"No, no," chuckled Miller, "we know that. It's just a question of method
that we want explained. Because somebody has done it, and we would like
to know how he managed it."

"Well, sir," said Polton, "there is no particular difficulty about it. He
would weigh up the 18-carat gold and take part of it, say a little more
than half, flatten it out on the stake or in a rolling mill, if he had
one, break it up quite small, and boil it up in nitric acid. That would
dissolve out the alloy--the copper and silver--and leave him pure gold.
Then he would melt that down with the proper proportion of the 18-carat
stuff, and that would give him 22-carat gold."

"And as to making the coins? Would that be much of a job? How many do you
think he could make in a day?"

"A man who knew his job," said Polton, "wouldn't make any trouble about
it. He would make his mould in a casting flask that would cast, say,
twenty at a time, and he would use a matrix that would dry hard and give
a good many repeats. There would be a bit of finishing work to do on each
coin--cutting off the sprue, where the metal ran in, and making good the
edge. But that is not a big job. They make a special edge tool for the
purpose."

"Oh, do they?" said Miller, with a sly grin. "You seem to know a good deal
about it, Mr. Polton."

"Of course I do," was the indignant response, "seeing that I have been
dealing with tool-makers in the metal trade since I was a boy. Not that
the respectable makers in Clerkenwell have anything to do with burglars'
and coiners' tools. But, naturally, they get to know what is made."

"Yes, I know," said Miller. "Our people get some useful tips from them,
now and again. And I shall know where to send them if they want some
more, eh, Mr. Polton? Technical tips, I mean, of course."

Polton crinkled indulgently at the Superintendent, and when the latter,
having glanced at his watch, suddenly emptied his glass and rose, his
expression became positively affectionate.

"I am afraid I have wasted a lot of your time with my gossip," said
Miller, apologetically, as he drew on his gloves, "but I thought you
would like to have the news. Probably you will look in at the Old Bailey
and see how the case goes. The sessions are just beginning now, and I
expect the case will come on in the course of a few days."

"We shall certainly drop in if we can," said Thorndyke, "and see what
comes of your efforts. Won't you throw away that stump and take a fresh
cigar?" he added, holding out the box as the Superintendent essayed to
strike a match.

"Seems a waste," replied Miller, turning a thrifty eye on the stump. But
he succumbed, nevertheless; and when he had selected a fresh cigar and
amputated its point with anxious care, he lit it (with a match that
Polton had struck in readiness), shook hands, and took his leave.

As the door closed on the sound of his retiring foot steps, Polton fell
to, in his noiseless, dexterous fashion, on the dismantling of the
dinner-table; and, as he prepared a tray for transport to the upper
regions, he announced:

"The camera is finished, sir, and all ready for inspection, if you have
time to come up and have a look at it."

"Then let us go up at once," said Thorndyke; "and perhaps we can take
some of the debris with us and save another journey."

He loaded a second tray and followed Polton up the stairs, while I
brought up the rear with an empty claret jug and a couple of dish covers.

The "automatic watcher," which its creator exhibited with justifiable
complacency, was a singularly ingenious appliance. The clock was enclosed
in a small box, on the front of which was a miniature dial; and the
almost inaudible tick was further muffled by a pad of felt between its
back and the wall. The camera, to which it was connected by an insulated
wire, was another small box, fitted with mirror plates to fasten it to
the door. From its front projected a brass tube, five inches long, and
half an inch thick, at the end of which was an enclosed prism with a
circular opening facing at right angles to the axis of the tube.

"There are two film holders," Polton explained, "each taking six yards of
kinematograph film, and each enclosed in a light-tight case with a
dark-slide, so that it can be taken out and another put in its place. So
I can go down and bring away one film for development and leave the other
to carry on. I have set the clock to make an exposure every six hours,
beginning at twelve o'clock, noon."

"And what about the shutter?" asked Thorndyke. "Does it make much of a
click?"

"It doesn't make any sound at all," replied Polton, "because it moves
quite slowly. It is just a disc with a hole in it. 'When the clock makes
the circuit, the disc moves so that the hole is opposite the lens; and
stays there until the circuit is broken. Then it moves round and closes
the lens, and, at the same time, the roller makes a turn and winds on a
fresh piece of film. I'll make an exposure now."

He turned the hand of the clock until it came to six, while Thorndyke and
I listened with our heads close to the camera. But no sound could be
heard; and it was only by repeating the proceeding with our ears actually
applied to the camera that it was possible to detect faint sounds of
movement as the shutter-disc revolved.

"I suppose," said Thorndyke, "you focus on the film?"

"Yes," replied Polton; "there's plenty to spare, so I use a piece as a
focusing screen and waste it. And the barrel of the lens can be turned so
as to get the prism pointing at the right spot. I think it will do, sir."

"I am sure it will," Thorndyke agreed, heartily; "and I only hope that
all your trouble and ingenuity and skill will not have been expended in
vain."

"That can hardly be, sir," was the cheerful response. "The photographs
are bound to show something, though it may not be exactly what you want.
At any rate, it's ready; and, with your permission, I will pop down with
it to-morrow, as soon as I have finished with the breakfasts."

"Excellent!" said Thorndyke. "Then, if Mrs. Gibbins's belief is well
founded, the 'watcher' will be installed in time for the Wednesday-night
visit."

Chapter XIII: Rex v. Dobey

DURING the next day or two, I was sensible of a certain tension and
unrest that seemed to affect the atmosphere of our chambers in King's
Bench Walk. Polton, having successfully installed his apparatus in the
corridor at Hartsden Manor House, was in a fever of impatience to harvest
the results. I believe that he would have liked to sit down beside his
camera and change the film after each exposure. As it was, he had fixed
it on Tuesday morning, and, as no result could be expected until
Thursday, at the earliest, circumstances condemned him to two whole days
of suspense.

But Polton was not the only sufferer. My long association with Thorndyke
enabled me to detect changes in his emotional states that were hidden
from the eye of the casual observer by his habitually calm and impassive
exterior; and, in these days, a certain gravity and preoccupation in his
manner conveyed to me the impression that something was weighing on his
mind. At first, I was disposed to connect his preoccupation with the
affairs of Hartsden Manor; but I soon dismissed this idea. For in those
affairs there was nothing that could reasonably cause him any anxiety.
And Thorndyke was by no means addicted to fussing unnecessarily.

The explanation came on the Wednesday evening, when we had finished
dinner and taken our armchairs, and were preparing the post-prandial
pipes.

"I suppose," said he, pushing the tobacco jar to my side of the little
table, "you will turn up at the Old Bailey to hear how Dobey fares?"

"When is the trial?" I asked.

"To-morrow," he replied. "I thought you knew."

"No," said I. "Miller didn't mention any date, and I have heard nothing
since. I think it would be interesting to hear the evidence, though we
know pretty well what it will be."

"Yes, we know the case for the prosecution. But we don't know what Dobey
may have to say in reply. That is what interests me. I am not at all
happy about the case. I don't much like the attitude of the prosecution--if
Miller has represented it fairly--particularly the dragging in of the
house affair."

"No," I agreed, "that seems quite irrelevant."

"It is," said he. "And it is a flagrant instance of the old forensic
dodge of proving the wrong conclusion. The identification of Dobey by
these women is evidently expected to convey to the jury in a vague sort
of way that the station-master's refusal to swear to the identity of the
Strood man is of no consequence."

"It is quite possible that the judge may refuse to allow the house affair
to be introduced at all."

"Quite," he agreed, "especially if the defence objects. But, still, I am
not happy about the case. The intention of the prosecution to introduce
this irrelevant matter to prejudice the jury and their suppression of the
evidence regarding the poisoned cigar--which really is highly
relevant--suggests a very determined effort to obtain a conviction."

"I take it that you do not entertain the possibility that Dobey may have
committed the murder?"

"No, I don't think I do. As you say, we know the case for the prosecution
and we know that it is a bad case. There is a total lack of positive
evidence. But, still, there is the chance that they may get a conviction.
That would be a disaster; and it would, at once, raise the question as to
what we should have to do. Obviously, we couldn't let an innocent man go
to the gallows. But it would be a very difficult position."

"What are the chances of a conviction, so far as you can see?"

"That depends on what Dobey has to say. The case for the prosecution
rests on the finding of the stolen document in his flat. There is no
denying that that is a highly incriminating circumstance, and, if he can
produce nothing more than a mere denial of having taken it, the chances
will be decidedly against him."

"It is difficult to see what answer he can give," said I. "The document
was certainly taken from Badger, before or after his death; it was
certainly found in Dobey's flat; and, apparently, Dobey was the sole
occupant of that flat. I don't see how he is going to escape from those
facts."

"Neither do I," said Thorndyke. "But we shall hear what he has to say
to-morrow; and if he is found guilty, we shall have to consider very
seriously what our next move is to be."

With this, the subject dropped. But, at intervals during the evening, my
thoughts went back to it, and I found myself wondering whether Thorndyke
had not perhaps allowed himself to undervalue the evidence against Dobey.
The finding of that document in his rooms would take a great deal of
explaining.

My intention to hear the case from the beginning was frustrated by a
troublesome solicitor, who first failed to keep an appointment, and then
detained me inordinately, so that when, at last, I arrived at the Central
Criminal Court and, having hurriedly donned my wig and gown, slipped into
the counsels' seats beside Thorndyke, the case for the prosecution was
nearly concluded. But by the fact that the finger-print expert was then
giving evidence, I knew that the prosecution had succeeded in introducing
the house breaking incident. As I listened to the evidence, I looked
quickly round the court to identify the various dramatis personae and,
naturally, looked first at the dock, where the prisoner stood "on his
deliverance," listening with stolid calm to the apparently
indestructible evidence of the expert.

As I looked him over critically, I was not surprised at the eagerness
with which the police had fastened on his salient peculiarities. He was
quite a striking figure. Dull and commonplace enough in face and feature,
the combination of a rather untidy mop of dark-red hair with a noticeably
red nose set in a large pale face made him an ideal subject for
identification. From the prisoner I turned to his defending solicitor,
Mr. Coleman, who sat at the solicitors' table, listening with sphinx-like
impassiveness to the expert's authoritative pronouncements. Equally
unmoved was the prisoner's counsel, a good-looking Jew named Lyon, who
specialized in criminal practice. The counsel for the prosecution, a Mr.
Barnes, was on his feet at the moment, and his junior, Mr. Callow, was
industriously taking notes of the evidence.

"Have the defence objected to this evidence?" I asked Thorndyke in a
whisper, as the leader for the Crown put what seemed to be his final
question.

"No," was the reply. "The judge questioned the relevance of it; but, as
the defence did not seem interested, he gave no ruling."

It seemed to me that Mr. Dobey's case was being rather mismanaged; and I
was confirmed in this opinion when his counsel rose to cross-examine:

"You have stated that the marks on this window glass are the prints of
the prisoner's fingers. Are you quite certain that those marks were not
made by the fingers of some other person?"

"The chances against their having been made by the fingers of any person
other than the prisoner are several thousand millions."

"But is it not possible that you may have made some mistake in the
comparison? You don't, I suppose, claim to be infallible?"

"I claim that the method employed at the Bureau is infallible. It does
not depend on personal judgment, but on comparison, detail by detail, of
the questioned finger-print with the one which is known. I have  made the
comparison with the greatest care, and I am certain that I have made no
mistake."

"And do you swear, positively, of your certain knowledge, that the marks
on this window-glass were made by the fingers of the prisoner?

"I do," was the reply; whereupon, having thus unnecessarily piled up the
evidence against his client, Mr. Lyon sat down with an air of calm
satisfaction. I was astonished at the apparent stupidity of the
proceeding. It is seldom worth while to cross-examine finger-print
experts at all closely, for the more they are pressed, the more do they
affirm their absolute certainty. And I noticed that my surprise seemed to
be shared by the judge, who glanced with a sort of impatient perplexity
from the counsel to the sphinx-like solicitor who was instructing him. It
must be an exasperating experience for a judge--who knows all the ropes--to
have to watch a counsel making a hopeless muddle of a case.

The next witness was a middle-aged woman who gave the name of Martha
Bunsbury, and who was examined by Mr. Barnes in the plain,
straightforward fashion proper to a prosecuting counsel.

"Kindly look at the prisoner and tell us whether you recognise him."

The witness bestowed a disdainful stare on the prisoner, and replied,
promptly: "Yes. I picked him out of a whole crowd at Brixton Prison."

"Where and when had you seen him before that?"

"I saw him on the second of August, breaking into a house in Sudbury
Park. I happened to be at the window at the back of my house when I heard
the sound of glass being broken. So I looked out, and then I saw the
prisoner getting into the back window of the house in Sudbury Park that
is just opposite mine. So I opened the window and called out. Then I ran
down to the garden and gave the alarm to two men who were coming along
the towing-path of the canal."

"And what happened next?"

"The lady next door to me came out into her garden and she began to call
out too. Then the two men started to run along the tow-path towards the
bridge, but the prisoner, who had heard us giving the alarm, backed out
of the window and ran across the garden with his coat on his arm. When he
came to the wall, he laid the coat on the top of it, because the wall has
broken glass all along the top, and climbed over. But, as he dropped down
outside, the coat dropped down inside. He turned round, and was going to
climb back to get it, but, by that time, the two men were running over
the bridge. So he left the coat and made off up a side lane between two
houses. And that is the last I saw of him."

"Yes. A very excellent description," said Mr. Barnes. "But now I want you
to be extremely careful. Look again at the prisoner, and see if you are
quite certain that he is really the man whom you saw in the garden of
that house. It is most important that there should be no possibility of a
mistake."

"There isn't," was the immediate and confident reply. "I am perfectly
certain that he is the man."

On this, Mr. Barnes sat down and Mr. Lyon rose to cross-examine.

"You have said that you saw the housebreaker from the back window of your
house, breaking a back window of a house opposite. How far would that
window be from yours?"

"I really couldn't say. A fair distance. Not so very far."

"You spoke of a canal. Is the opposite house on the same side of the
canal as your house?"

"No, of course it isn't. How could it be? It is on the opposite side."

"And how long is your garden?"

"Oh, a moderate length. You know what London gardens are."

"Should I be right in saying that, at the time that you saw this man, you
were separated from him by the length of two gardens and the width of the
canal?"

"Yes. That is what I said."

"And you say that, having seen this total stranger at that very
considerable distance, you are quite certain that you are able to
recognize and remember him?"

"Yes, I am quite certain."

"Can you tell us how you are able to identify him with such certainty?"

"Well," said the witness, "there's his nose, you see. I could see that."

"Quite so. You looked upon the nose when it was red."

"I should think it is always red," said Mrs. Bunsbury. "At any rate, it
was red then, and it is red now. And then there is his hair."

"Very true. There is his hair. But he is not the only man in the world
with a red nose and red hair."

"I don't know anything about that," replied the witness, doggedly. "But I
do know that he is the man. I'd swear to him among ten thousand."

This apparently finished Mr. Lyon, for, having again prejudiced his
client's case to the best of his ability, he sat down with unimpaired
complacency.

The next witness, Miss Doris Gray, gave evidence to the same effect,
though with somewhat less emphasis; and, when she had been cross-examined
and finally vacated the witness-box, Mr. Barnes rose and announced that
"that was his case." As soon as he sat down, Mr. Lyon rose and made his
announcement.

"I call witnesses, my lord."

"Now," Thorndyke said to me in a low tone, "we are going to see whether
there is really a case for the defence."

"They haven't made much of it up to the present," I remarked.

"Exactly," he replied. "That is what makes me a little hopeful. They have
certainly given the prosecution plenty of rope."

I should have liked to have this observation elucidated somewhat--and
so, probably, would Superintendent Miller, who, at this moment, came
forth from some inconspicuous corner and took his place at the
solicitors' table; for there was more than a shade of anxiety on his face
as he looked expectantly at the witness-box. But there was no opportunity
for explanations. Even as Miller took his seat, the first witness for the
defence was called, and appeared in the person of a pleasant-looking
middle-aged lady wearing the uniform of a trained nurse, and bearing, it
transpired, the name of Helen Royden. In reply to a question from Mr.
Lyon, she deposed that she was the matron of the cottage hospital at Hook
Green, near Biddenden in Kent.

"Will you kindly look at the prisoner and tell us if you recognize him?"

The witness turned her head and cast a smiling glance at the accused
(whereupon Mr. Dobey's rather saturnine countenance relaxed into a
friendly grin), "Yes," she replied, "I recognize him as Mr. Charles
Dobey, lately a patient at my hospital."

"When did you last see him?"

"On the first of October, when he was discharged from hospital."

"What were the date and the circumstances of his admission?"

"He was brought to the hospital on the thirtieth of July by Dr. Wale, the
medical officer of the hospital, suffering from a compound fracture of
the left tibia. I understand that the doctor found him lying in the
road."

"Do you remember the exact time at which he was brought in?"

"It was a little before eleven in the forenoon." As the dates were
mentioned, I observed the judge and the two prosecuting counsel hurriedly
turn over their notes with an expression of astonishment and incredulity,
and the jury very visibly "sat up and took notice."

"Did you communicate with any of the patient's relatives?"

"Yes. At the patient's request, I wrote to his wife, who lives at East
Malling in Kent, informing her of his admission, and inviting her to come
and see him."

"And did she come?"

"Yes. She came the next day, and I allowed her to stay the night at the
hospital. After that, she came to see him usually twice a week."

"Have you any doubt that the prisoner is the man whom you have described
as your patient, Charles Dobey?"

"No. I couldn't very well be mistaken. He was in the hospital just over
two months, and I saw him several times every day, and often had quite
long talks with him. Ours is a small hospital, and the patients are
rather like a family."

"Did you learn what his occupation was?"

"Yes. He described himself as a plumber and gas-fitter."

"Had you any reason to doubt that that was his real occupation?"

"None whatever. In fact, we had evidence that it was; for, when he was
convalescent and able to get about, he repaired all the taps in the
hospital, and did a number of odd jobs. He seemed to be quite a clever
workman."

"Do you keep a record of admissions and discharges?"

"Yes. I have brought the register with me."

Here she produced from a business-like hand-bag a rather chubby quarto
volume which she opened at a marked place and handed to the usher,
who conveyed it to the counsel. When the latter had examined it and
verified the dates, he passed it up to the judge, who scanned it
curiously and compared it with his notes. Finally, it was handed to
the prosecuting counsel, who appeared to gaze on it with stupefaction,
and returned it to Mr. Lyon, who handed it back to the usher for
transmission to the witness. This concluded the examination-in-chief,
and Mr. Lyon accordingly thanked the witness and sat down. I waited
curiously for the cross-examination, but neither of the Crown counsel
made any sign. The judge glanced at them enquiringly, and, after a
short pause, the witness was dismissed and her place taken by her
successor. The new witness was a shrewd-looking, clean-shaved man, in
whom I seemed to recognize a professional brother. And a doctor he
turned out to be; one Egbert Wale by name, and the medical officer of
the Hook Green Cottage Hospital. Having given the usual particulars,
and been asked the inevitable question, he deposed as follows:

"On the thirtieth of last July, at about twenty minutes to eleven in the
forenoon, I was driving down a by-road between Headcorn and Biddenden
when I saw a man lying in the road. I stopped my car and got out to
examine him, when I found that he had sustained a compound fracture of
the left leg below the knee. I accordingly dressed the wound, put on a
temporary splint, lifted him into my car, and drove him to the Hook Green
Cottage Hospital, of which I am visiting medical officer. He gave the name
of Charles Dobey, and explained that he had broken his leg in dropping
from a motor-lorry on which he had taken a free lift without the
knowledge of the driver. I detained him in the hospital for two months,
and discharged him as convalescent on the first of October."

"Did Dobey make a good recovery?"

"Yes, excellent. When he left the hospital, the wound was quite healed,
and the broken bone firmly united, but there was a large knob of
callus, or new bone, which, I hope, will disappear in time."

 "Would you recognize the wound if you were to examine it?"

 "Certainly I should. I saw it last only about three weeks ago."

 "Then, if his lordship will grant his permission, I will ask you to make
the examination."

His lordship--bearing in mind; no doubt, the evidence of the
finger-print experts--gave his permission readily; whereupon the
doctor came out of the witness-box and went over to the dock. There he
proceeded dexterously to unwind a length of bandage from the prisoner's
leg--which had been exposed by its owner in readiness for the
inspection--and examine the member by sight and touch. Then he replaced
the bandage and returned to the witness-box.

 "What is the result of your examination?" Mr. Lyon asked.

"I find the wound and the fracture in much the same condition as when I
saw it last about three weeks ago."

 "You have no doubt that it is the same injury?"

 "Not the slightest. I recognize every detail of it."

"What is meant by a compound fracture? Is it a very serious injury?"

"A compound fracture is a break in a bone accompanied by a wound of the
flesh and skin which communicates with the broken part of the bone and
exposes it to the air. It is always a serious injury, even under modern
surgical conditions, because the wound and the fracture have both to be
treated, and each may interfere with the treatment of the other."

 "And you have no doubt that the prisoner is the person whom you treated
at the hospital?"

"I identify the prisoner as the man of whom I am speaking. I am quite
certain that he is the same person."

On receiving this answer, Mr. Lyon sat down, and the witness looked
expectantly at the counsel for the prosecution. But, as before, they
made no sign, and, accordingly, the witness was dismissed. As he
retired, the foreman of the jury rose and announced that he and his
colleagues did not want to hear any more evidence. "The jury are of
opinion," he added, "that this is a case of mistaken identity."

"It is difficult to avoid that conclusion," the judge admitted. Then,
turning to the prisoner's counsel, he enquired what further evidence he
had proposed to offer. "I had proposed to call the prisoner's wife, my
lord, and then to put the prisoner in the box."

The judge reflected for a few moments and then, addressing the foreman,
said: "I think, in fairness to the prisoner, we should hear the rest of
the evidence. You will note that the question of the document has not
been cleared up. That document was found, you will remember, on premises
belonging to the prisoner. We had better hear the evidence, though it may
not be necessary for the learned counsel for the defence to address you."
The jury having agreed to this eminently sensible suggestion, the
prisoner's wife, Elizabeth Dobey, was called and took her place in the
witness-box.

"Is the address at East Mailing that you have given your permanent
address? Is that your home?" Mr. Lyon asked, when the preliminaries had
been disposed of, and the witness had described herself as the wife of
Charles Dobey, the prisoner, "Yes. We rent a cottage with a nice bit of
garden. My husband is very fond of gardening."

"With regard to the flat in London, 103 Barnard's Buildings? Do you spend
much of your time there?"

"Me? I have never been there at all. It isn't a flat. It's just a place
where my husband can sleep and cook a meal when he is in Town, looking
for a job."

"Do you remember when the prisoner first went up to Barnard's Buildings
after he came home from the hospital?"

"He only went up once. That was when the police took him. It was about a
week after he came home--on the eighth of October."

"Did he send anyone else up to the flat, before he went himself?"

"No. There wasn't anyone to send, and there wasn't any reason to send
them." This concluded the examination-in-chief. But, this time, as Mr.
Lyon resumed his seat, Mr. Barnes rose with remarkable promptitude. "You
have said that your husband kept this flat in London to sleep in when he
was looking for a job. What kind of jobs would he be looking for?"

"He is a plumber and gas-fitter by trade. He would be looking for jobs in
his own line, of course."

"You have heard the police witnesses state that they found in that flat a
number of burglars' tools, a quantity of stolen jewellery, and a stolen
document. Do those tools and that stolen property suggest anything to you
as to the kind of jobs that your husband went to London to look for?"

"No, they have got nothing to do with his trade."

"Can you account for the presence of burglars' tools and stolen property
in the rooms of a plumber and gas-fitter?"

"Yes, I can," Mrs. Dobey replied, viciously, "after all the false
swearing that there has been in this court to-day. If you ask me, I
should say that the police put them there." At this rather unexpected
reply a low rumble of laughter filled the court, including the jury box;
and a faint, appreciative smile stole over the judge's face, and was even
reflected on the countenance of Mr. Barnes himself.

"I am afraid," he said, good-humouredly, "that you are taking a
prejudiced view. But with regard to this flat; have you ever taken any
measures to ascertain what your husband does at those rooms?"

"No," she replied. "I don't go spying on my husband. It isn't necessary.
I can trust him, if other people can't."

Here it apparently dawned upon Mr. Barnes that he was not going to do his
case any good with this witness, Accordingly, he thanked her, and resumed
his seat; and, as Mr. Lyon was not disposed to re-examine, Mrs. Dobey
retired in triumph, and her husband was conducted from the dock to the
witness-box.

When he had been sworn and had given the usual particulars, his counsel
directed him to describe his movements after his escape from the prison,
which he did with picturesque conciseness.

"As soon as I was clear of the prison, I scooted round a corner into a
by-street, and there I saw a motor wagon piled up with empty baskets. The
driver was cranking up the engine, and, as there was nobody in sight, I
climbed up behind and laid down on the floor among the baskets. Then the
driver got up and off she went. When we got out somewhere between
Headcorn and Biddenden the wagon turned down a by-lane, and as I thought
that we might be getting near the farm that we seemed to be bound for, I
decided to hop off. So I did. But she was going faster than I thought,
and I came down a cropper and broke my leg. I laid there in the road for
about a quarter of an hour, and then the doctor came along and picked me
up, and took me off to the hospital. And there I stayed until I was
discharged on the first of October."

"When did you first go up to your London flat?"

"I only went once. That was when I had been at home just over a week--on
the eighth of October. The detectives came and collared me just as I was
picking the lock to let myself in."

"Why did you have to pick the lock?"

"Because I hadn't got my key. They took all the things out of my pockets
at Maidstone police-station. But I had forgotten that I hadn't got my key
until I was close to the Buildings, so I had to pop into an ironmonger's
shop and get a piece of wire. And I was picking the lock with that piece
of wire when the cops nabbed me."

"You have heard about the burglars' tools and the stolen property that
the police found in your room. Can you tell us anything about them?"

"No, I don't know anything about them. They were not mine, and I didn't
put them there. Somebody must have got into the rooms and planted them
there while I was in the hospital."

"Have you any idea who might have planted those things, and for what
purpose?"

"I should think anyone could see what they were planted for. It was to
put this murder on to me. But, as to who planted them, if the police
didn't--and I suppose they didn't, though they do seem to have been
working the oracle a bit--it must have been the person who did the
murder, seeing that he had got the paper that was taken from the murdered
man."

"Do you swear that you never went to the flat after leaving the hospital
until the eighth of October?"

"I do. I shouldn't have gone there a second time with a bit of wire to
let myself in. I should have got a key."

This was Mr. Lyon's final question, and, as he sat down, Mr. Barnes rose
to cross-examine, but with no great show of enthusiasm. He began by
pressing the witness for a clearer explanation of the purpose for which
he kept the rooms in London. But at this point the foreman of the jury
again intervened with a protest that the jury were not interested in the
prisoner's occupation, and that they did not want to hear any more
evidence; whereupon Mr. Barnes sat down with no appearance of reluctance,
and the judge enquired of Mr. Lyon if he desired to address the jury.

"If the gentlemen of the jury have come to a decision," was the reply,
"it would be useless for me to occupy the time of the court with an
address."

Accordingly, the prisoner was led back to the dock, and the judge
proceeded to make a few observations.

"I do not pretend to understand this case," said he. "We have been told
that it is an impossibility for two different persons to have identically
similar finger-prints. Yet, here, the impossible seems to have happened.
Finger-prints which have been identified as those of the prisoner were
made in a house in London on the second of August; at which time the
prisoner appears to have been lying, with a broken leg, in a hospital
some forty miles away. It would seem that there is some person whose
finger-prints are identical with those of the prisoner; and,
unfortunately for the prisoner, that person appears to be a
house-breaker. However, there is no use in trying to resolve this puzzle,
for, after all, the question is not relevant to the issue that you are
trying. What you have to decide is whether you are prepared to accept as
true the evidence of the matron of the hospital and Dr. Wale. If their
evidence is true, it is physically impossible that the prisoner could
have committed the murder with which he is charged. That is for you to
decide, and I do not think that I need say anything more."

When the judge had finished speaking, the grey-wigged clerk of the court
rose and put the formal question:

"Are you all agreed upon your verdict, gentlemen?"

To which the foreman replied, promptly: "We are."

"What do you say, gentlemen? Is the prisoner guilty or not guilty?"

"Not guilty," was the reply, delivered with noticeable emphasis.

The judge briefly expressed his entire concurrence, and then proceeded:

"I understand that the prisoner, having escaped from prison while
awaiting his trial, is still in custody, on the original charge. Have you
any instructions on the subject?

"Yes, my lord," replied Mr. Barnes. "It appears that the bill was
presented to the Grand Jury at Maidstone on the day on which the prisoner
absconded. There would seem to have been some error in presenting the
bill; but, at any rate, the Grand Jury threw it out."

"I am glad to hear that," said the judge. Then, addressing the prisoner,
he continued: "Charles Dobey, you have been tried for the crime on which
you were indicted, and have been found not guilty--very properly, as I
think--and, as the bill in respect of the original offence has been
thrown out by the Grand Jury at Maidstone, there is now no charge against
you, and you are accordingly discharged."

He accompanied the rather dry statement with a smile and a kindly nod,
which Dobey acknowledged with a low bow, and, as the gate of the dock was
now thrown open, he descended to meet, with a somewhat stolid grin, the
effusive greetings of his wife and the congratulations of his friends
from the hospital.

"Well," I said, as we rose to depart, "I hope you find the result of the
trial satisfactory."

"I do," Thorndyke replied, "but I don't think Miller does. He looks most
uncommonly glum. But I do not feel sympathetic. The police--if they
instructed the prosecution--have been hoist with their own petard. They
insisted on dragging in these finger-prints and those two women, whose
evidence was quite irrelevant and was intended merely to discredit the
prisoner, and behold the result. From this time forward, Dobey is
practically immune from finger-print evidence and evidence of personal
identification. He can prove, from the records of this trial, that there
is some person, who is engaged in the practice of house breaking, who is
in appearance his exact double, and whose finger-prints are identically
similar to his. He can actually quote the judge to that effect."

"Yes," I agreed. "Dobey need not trouble to wear gloves now, if he really
is a cracksman, as I have no doubt he is. One cannot help admiring the
masterly strategy of the defence in egging on the prosecution to play
their trump cards and prove those very facts. But, even now, I don't see
how you came to be so certain of Dobey's innocence. You knew nothing
about the alibi. And, apart from that, there was a case against him. Yet,
apparently, you never entertained the possibility of his being guilty."

"I don't think I did," he admitted; "and, if you will reconsider the case
in general terms and in detail, I think you will see why. Let me
recommend you to do this now, as the completion of the case devolves on
us. I must stay and have a few words with Miller; and I suggest that you
go on ahead and spend half an hour in going over the case with an open
mind. You know where to find our notes of the case. Get them out and look
them through. Note all the facts that are known to us, consider them
separately and as a whole, and see if there does not emerge a perfectly
coherent theory of the crime. The evidence that you have heard to-day,
inasmuch as it is in agreement with that theory, ought to be helpful to
you."

"When you speak of a theory of the crime," said I, "do you mean a general
theory, or one capable of a particular application?"

"Our function," he replied, "is to discover the identity of the person
who murdered Inspector Badger; and the theory that I refer to is one
which is capable of leading us to that discovery."

With this he stepped out into the body of the court to go in search of
the Superintendent, and I made my way to the robing-room to divest myself
of wig and gown before issuing forth into places of public resort.

Chapter XIV: A Startling Discovery

ON my way westward from the Old Bailey to the Temple, I turned over in my
mind Thorndyke's last statement. Its exact meaning was not perfectly
clear to me; but what I did gather was that he had enough knowledge of
the circumstances surrounding Badger's death to make the belief in
Dobey's guilt untenable. That implied some positive knowledge pointing to
the guilt of some other person; but as to whether that other person was
an actual individual to whom a name could be given, or a mere abstraction
whom we had yet to convert into a reality, I was unable to decide. What
did, however, emerge clearly from his statement was that whatever facts
were known to him were also known to me. My problem, therefore, was to
examine the facts that I already knew, and try to extract their
significance, which I had apparently missed up to the present.

When I arrived at our chambers, I became aware, by certain familiar
signs, that Polton had returned from his expedition to Hartsden, and was
engaged in some kind of photographic work in the laboratory. Presumably,
he was developing the films from the "automatic watcher," and I was
tempted to go up and see what luck he had had. But I restrained my
curiosity, and, having drawn a chair up to the table and procured a
note-block and pencil, I went to the cabinet in which the portfolios of
current cases were kept and unlocked it. The one labelled "Inspector
Badger, deceased," was uppermost, with the finger-print measuring-glass
lying on its cover. I lifted them out together, and, laying the glass on
the table, opened the portfolio and began to glance through its contents,
laying the papers out in their order as to the dates.

The first that I picked up I put aside, as it did not appear to belong to
the series. It was a rough copy of the entry that Thorndyke had made in
his note-book when we were experimenting on the Thumbograph, and had
apparently been put in the portfolio out of the way--though it was
extremely unlike Thorndyke to put anything in its wrong place. Then I
began to go through the various notes, seriatim, trying to refresh my
memory as to the order of the events and the way in which the case had
developed. But as I turned over the notes, I was aware of a growing sense
of disappointment. There was nothing new; nothing that I did not remember
quite clearly without their aid. I glanced through the brief notes of our
expedition to Greenhithe. It was all fresh in my memory. The description
of the body, the examination of the tunnel, the finding of the cigar;
then the analysis of the cigar, the report of the inquest, and the
evidence of the witnesses. I knew it all, and it conveyed nothing to me
but a mysterious crime of which we held not a single clue to guide us to
the identity of the perpetrator. There was a brief summary of Miller's
account of the house-breaking incident, which did now, after the event,
point pretty definitely to a personation and the making of false
finger-prints. But there was no suggestion as to the identity of the
personator. To me, the whole case remained in the air.

At the end of the portfolio was a separate folder labelled
"finger-prints," which I took out, doggedly, but with a sense of deep
discouragement. Nothing could be much less illuminating than a collection
of unidentified finger-prints. Nevertheless, I opened the folder and
began to look through the collection. There were Badger's prints, devoid
of any meaning to me, and the photograph of Dobey's, taken from the
official paper that Miller had shown us, which told me nothing at all.
Then I opened a smaller folder, labelled "Prints from cigar." There were
two sets of photographs, one the natural size and the other enlarged to
about four diameters. Discarding the smaller photographs, I examined the
enlargements, and read the inscriptions written below them, with as much
attention as I could muster; for, little as they conveyed to me, I
realized that they constituted evidence of the highest importance, if
only the opportunity should ever come to apply it.

The first was Inspector Badger's left thumb, remarkably clear for a
developed print. But, though it was, in effect, an indictment of murder,
it gave me no help, since I knew already that poor Badger had been
murdered. I laid it down and took up the next. "Right thumb of person
unknown." Having read the inscription, I glanced at the print. This one,
too, was admirably clear and distinct. The experts should have no
difficulty in identifying it if they could get a known print with which
to compare it. Not only was the general pattern--a very distinctive
one--perfectly plain, but all the minor "characteristics" were easily
legible.

I sat with the print in my hand and my eyes fixed on it musingly,
reflecting on all that it meant and all that it did not mean. This
thumb-print had been made by the man who had given the poisoned cigar to
poor Badger--who had almost certainly murdered him; who had personated
Dobey at the sham house-breaking, and who had entered Dobey's flat and
there planted the stolen document. It was capable of giving infallible
proof of that villain's identity; and yet it offered not the faintest
hint as to what manner of man that villain might be. In spite of our
possession of this infallible touchstone we might pass this murderer in
the street a hundred times without the faintest glimmer of suspicion as
to who he was. A finger-print is a poor instrument with which to start
the search for an unknown criminal.

As I sat thus, with my eyes fixed only half-consciously on the print, I
became aware of a dim sense of familiarity. A finger-print is, to an
accustomed eye, much more easy to remember than might be supposed; and,
as my eye rested on this print, I began to have the feeling that I had
seen it before. At first the feeling was not more than vaguely
reminiscent; but yet it was enough to arouse my attention. I looked, now,
with a critical and purposeful scrutiny and a definite effort of memory.
And then, suddenly, in a flash, the revelation came and left me gazing
open-mouthed.

It was amazing, incredible; so incredible that I sought instantly for
corroboration or disproof. Snatching up the measuring-glass, and picking
out the natural-sized print, I placed the central dot of the scale of
circles on the summit of the central character of the core and wrote down
on the note-block the measurements shown. The pattern was intermediate
between a whorl and a twinned loop; but, remembering Thorndyke's rule, I
treated it as a whorl. Then, as it was a left-handed, or anti-clockwise,
whorl, and as the "core-character" lay entirely within the centre circle
("Space A"), the whorl was of the type A3. I wrote this down, and then
measured the distance to the right delta. The latter was intersected by
the circle, C, and therefore, by the rule, lay in the space, D. The ridge
tracing was clearly outside the delta, and I therefore wrote down O. The
left delta was outside the print, and therefore could not be located. The
number of ridges between the centre of the core and the right delta was
twelve, while the left ridge-count--since the left delta was outside the
print--was unascertainable.

When I had finished, I set out my results in the regular formula, so far
as I remembered the method, thus:

Right thumb--Unknown.
W (? T.L.). Core, A3, ?, O, D, ?, 12.

Then I turned back through the portfolio until I found the slip of paper
on which Thorndyke had copied the entry in his note-book. The first eager
glance at it I showed me that my memory had not deceived me.

The entry ran:

Walter Hornby. Right thumb.
W (? T.L.). Core, A3, ? , O, D, ?, 12.

In addition to the formula, Thorndyke had written down a few of the
"ridge characteristics" with their ridge-counts from the centre of the
core, and a direction-arrow to show their position, thus:

-}3, Lake, 5, Bif., 8, End, 10, Bif.
{-7, Lake, 9, Bif., 11, Lake.

With intense excitement, I proceeded to verify these characters, not a
little surprised at the ease with which they could be recognized and
located. Taking first the right direction-arrow, and counting the ridges
from the centre of the core, I found in the third ridge one of those
little loops, or eyes, known, technically, as "lakes." The fifth ridge
divided into a fork, or bifurcation; the eighth ridge terminated abruptly
in a free end, and the tenth showed another bifurcation. Then, following
the left direction-arrow, the seventh ridge showed a small lake, the
ninth a bifurcation, and the eleventh a larger lake. The agreement was
complete in every detail.

I laid down the print and reflected on this amazing discovery, still
hardly able to credit the evidence of my eyes. For the thing seemed
beyond belief. The murderous wretch whose tracks we had been following
was none other than Walter Hornby. After all these years, during which I
had almost forgotten his very existence, he had suddenly swum into the
field of our vision like some strange and horrible apparition. Yet my
astonishment was hardly justified; for no detail of his recent villainy
was in any way out of character with his past, as it was known to me.

Presently my thoughts took another turn. By what means had Thorndyke been
able to identify Badger's murderer as Walter Hornby? It had been no
chance shot. The discovery of Hornby's thumb-print in the Thumbograph had
been no mere accident. It was now evident to me that Thorndyke had come
to our house with the express purpose of seeking that thumb-print, if it
was in existence, as was manifest from the fact that he had come equipped
with the measuring-glass, and from the anxiety that he had shown as to
the fate of the Thumbograph. Clearly, that was the final verification of
a theory that was already complete in his mind. Indeed, he had, in
effect, said as much this very day in court. He had spoken of "a coherent
theory of the crime," an expression that would have been quite
inapplicable to the chance discovery of a finger-print. Now, how, from
the information that we possessed, had he arrived at this astonishing
conclusion?

It is proverbially easy to be wise after the event. "Jobbing back," as
this mental exercise is named on the Stock Exchange, is considerably
simpler than jobbing forward. So I found it on the present occasion. Now
that the conclusion was known to me, I was in a favourable position to
consider the processes of reasoning which had led to it. And when I did
so, and when I recalled the hints that Thorndyke had dropped from time to
time, I was surprised that no inkling of the truth had ever dawned on me.
For what Thorndyke had said was perfectly true. When all the facts were
considered, separately and as a whole, a consistent theory of the crime
emerged, and inevitably brought the figure of Walter Hornby into the
picture.

Taking the facts separately there were those that related to technique
and method and those that related to motive. The technique in the present
crime included the use of a poisoned cigar and of counterfeit
finger-prints. But this was the technique employed, years ago, by Walter
Hornby; and it was not only a peculiar and distinctive technique; it was
absolutely unique. No other criminal, so far as I had ever heard, had
employed it. Then the method of employing it was the same in both cases.
In the Hornby case--the case of the Red Thumb Mark--an original
finger-print (in the Thumbograph) had been obtained from the victim,
Reuben Hornby, from which to make, by photo mechanical process,
the stamps for the counterfeits. In the Badger case, a sheet of
finger-prints had been stolen, evidently for the same purpose. Again,
in both cases, the forged finger-prints had been "planted" at the scene
of the crime. In short, the technique and method in the Badger case
repeated, in the main, those of the Red Thumb Mark case.

Then the motive showed a like similarity in the two cases. When Walter
Hornby had tried to murder Thorndyke (by means of a poisoned cigar) his
motive was to get rid of the only person who suspected him. As to the
motive for the murder of Badger, Miller was almost certainly right,
although he had guessed wrong as to the identity of the murderer.
Badger's uncanny memory for faces had made him a dangerous enemy. And we
had Miller's statement that Badger was the only officer who was able to
identify Walter Hornby.

Finally, taking the whole set of facts together, the similarity of the
two cases was very striking. In each crime, the criminal act had been
preceded by a careful preparation to incriminate an innocent person.
There had been a systematic scheme of false evidence, thought out and
arranged in advance with remarkable completeness and ingenuity, before
the criminal had committed himself. Thus, as a whole and in detail, the
murder of Inspector Badger virtually repeated a crime which was known to
me, and which was utterly unlike any other crime of which I had ever
heard. Reluctantly, I had to admit that I had been distinctly "slow in
the uptake."

I had just reached this rather unsatisfactory conclusion when I heard a
latchkey inserted in the outer door. A moment later, Thorndyke entered,
and, as his eye lighted on the open portfolio, be greeted me with the
enquiry:

"Well, what says my learned friend? Has he reached any conclusion?"

By way of answer, I wrote on a scrap of paper: "x=Walter Hornby," and
pushed it along the table towards him.

"Yes," he said, when he had glanced at it, "history repeats itself. We
had this equation once before, you remember."

"I remember," said I, "and I ought to have remembered sooner. But, tell
me, Thorndyke, when did you first suspect Hornby in this case?"

"The word 'suspect,'" he replied, "is a little indefinite. But I may say
that when we established the fact of a poisoned cigar, the name of Walter
Hornby inevitably floated into my mind, especially as the cigar was
associated with a stolen sheet of finger-prints which were pretty
evidently not those of the person who stole them. In fact, I adopted,
provisionally, the hypothesis that the murderer was Walter Hornby, but
only as a mere possibility which had to be borne in mind while further
developments were being watched for. I argued that if the hypothesis was
correct, certain events might be confidently expected to follow. There
would be some crime, probably committed in daylight by a man with red
hair and a red nose, who would leave Frederick Smith's finger-prints at
the scene of the crime; and the stolen paper would be found in some place
connected with Frederick Smith.

"As you know, these events occurred exactly according to plan. Thereupon,
the mere hypothesis became a very weighty probability. But the experimentum
crucis was made possible by Juliet. When the Thumbograph had spoken the
hypothesis passed into the domain of established fact."

"Yes," I said; "you have established the murderer's identity beyond any
reasonable doubt. The next thing is to ascertain his whereabouts. At
present he is no more than a name."

"That," he replied, "is Miller's problem. The police have all the
facilities for finding a wanted man. We have none. By the way, have, you
seen Polton?"

"No," I replied, "but I expect you will see him before long. He always
knows, in some occult way, when you come in. In fact, I think I hear him
approaching at this moment."

Almost as I spoke, the door opened and Polton entered, bearing a large
vulcanite dish and a long strip of cinematograph film. There was no need
to ask for his news, for his face was one large and incredibly crinkly
smile of triumph and satisfaction.

"We've brought it off, sir," he announced, gleefully, "first shot. I went
down to the Manor House this morning, and I waited by the camera until I
heard the twelve-o'clock exposure go off. Then I took out the roll-holder
and put in a fresh one. But I don't think you will want it. I have
developed the strip--nine exposures, altogether, but only two of them
matter, and those two I have enlarged to half-plate. They are those made
at twelve o'clock on Tuesday and twelve o'clock to-day."

He laid the dish on the table, and watched Thorndyke ecstatically as the
latter stooped over it to examine the enlargements.

"The top one is the Tuesday exposure," he explained. "Shows the room just
as you saw it, with the box on the table. The bottom one is to-day's. You
see there's no box there, and the arm-chair has been moved about a couple
of inches, as you can see by the sash of the case behind it."

"Yes," Thorndyke agreed, "it is a true bill, Polton. The box is gone from
the table; and boxes don't fly away of themselves. By the way, Polton,
what do you make of that box?"

"Well, sir," was the reply, "if it didn't seem so unlikely, I should have
said that it looked like a casting-box; one of those biggish flasks that
silversmiths use for casting the blanks of things like spoons. It is
certainly a metal box, and those things at the side look very much like
pin-lugs."

"So I thought," said Thorndyke; "but we shall probably know all about it,
before long. At any rate, Polton, you have solved our problem for us, and
now we can go ahead with confidence. I shall send Mr. Woodburn a letter
and a telegram. He will probably get the letter to-morrow morning, but
the telegram will make it safer."

"There's the telephone, sir," Polton suggested.

"Yes, I know," said Thorndyke "but when I whisper secrets, I like to know
whose ear they are going into."

"What are you going to say to him?" I asked.

"I shall ask him to meet us to-morrow morning and bring the key of the
gallery door. That is what we arranged."

"Then you are going to break the seals and explore the rooms?"

"Certainly. There is now no doubt that someone visits those rooms; and as
the next visit seems to be due to-morrow night, we may as well be there
to give the visitor a hospitable reception."

"Shall you want me to come with you, sir?" Polton enquired, anxiously.

My impression was that Thorndyke did not particularly want him. But the
wistfulness of the little man's face proved irresistible.

"I think you had better come, Polton," he said, "and bring a few tools
with you. But it would be as well if you went on ahead of us, so that we
don't make too large a party. We mustn't be too noticeable."

"No, sir," Polton agreed, undisguisedly jubilant at being included in the
expeditionary party; "I will go down by the early train. Are there any
tools in particular that you wish me to bring?"

"Well, Polton," Thorndyke replied, "you know what our problem is. Someone
has got into these rooms by some means other than an ordinary door. We
may have to pick one or two locks, and they may be rather unusual locks.
I would not suggest burglars' tools, because, of course, you haven't any.
If you had, they might be useful."

Polton crinkled knowingly as he protested "There is nothing improper
about burglars' tools in themselves. It is the use that is made of them.
The tools are quite innocent if they are used for a lawful purpose."

Having delivered himself of this slightly questionable legal dictum, he
departed, leaving the photographs for us to examine at our leisure.

Very curious productions they were. I took up the strip of film and
examined the tiny negatives through my pocket lens. Small as they
were--barely an inch and a half square--they were full of minute
detail, and the enlargements, magnified about four diameters, were
as clear as if they had been taken with a full-sized camera. The
"Automatic Watcher" had turned out, in respect of its efficiency, far
beyond my expectations.

"Yes," said Thorndyke, in reply to my admiring comments, "with
first-class lenses, you can get surprising results; in fact, the only
limit to enlargement is the grain of the film. But we had better put the
photographs away for the present, as I am expecting Miller to drop in at
any moment. He is dreadfully disgruntled at the result of the trial,
though the fiasco is very largely of his own producing. Still, we shall
have to try to comfort him, and it had occurred to me that we might take
him into this Hartsden adventure. What do you think? We really ought to
have a police officer with us."

"Yes, I think it is rather necessary," I agreed. "We don't want a search
warrant, as we are acting with Woodburn's authority, but, as we may have
to make an arrest, it would be more regular to have a police officer to
direct that part of the business. Besides, we don't know how many we may
have to deal with. It looks like a one-man job, but we don't know. It may
turn out to be a gang. Let us have Miller's beef and experience, by all
means."

On this, Thorndyke took the photographs and retired to the laboratory to
write and dispatch his letter and telegram. When he returned, he brought
in with him the Superintendent, whom he had encountered on the landing.

"Well," growled Miller, as I placed an arm-chair for him, with the usual
creature comforts, "we've brought our pigs to a pretty fine market."

Thorndyke chuckled, but refrained from pointing out that the market was
of his own choosing.

"What I can't understand," the Superintendent continued, "is why that
fool couldn't have trotted out his infernal alibi when we charged him.
Then there needn't have been any trial."

Again we refrained from the obvious answer to this question. Instead,
Thorndyke proceeded at once to the "comforting" operation.

"Well, Miller," said he, "now that we have cleared Dobey off the stage,
we can give our attention to realities. I suppose you will now agree with
me that the man who gave Badger that poisoned cigar is the man who
murdered him."

"Yes," Miller admitted, "I'll agree to that much. But it doesn't get us a
great deal forrarder. The fellow is a mere abstraction. He isn't even a
name. He is just a finger-print that we haven't got on our files."

"Not at all," said Thorndyke. "We can tell you who he is. It will then be
for you to find out where he is."

The Superintendent laid down a match that he had just struck, and stared
at Thorndyke, open-mouthed.

"You can tell me who he is!" he exclaimed. "Do you mean that you can give
him a name?"

"I do," replied Thorndyke. "His name is Walter Hornby."

The Superintendent was thunderstruck. "Walter Hornby!" he gasped in
amazement. Then, suddenly, he brought his large hand down heavily on the
little table, causing it to rock visibly, to the imminent peril of the
whisky decanter. "Now," he exclaimed, "I understand how it happened.
Badger told me, himself, that he thought he had seen Walter Hornby, and
he was mighty pleased with himself for having spotted him. I gathered
that Hornby was either very much changed or else disguised, though Badger
didn't actually say so. But I have no doubt that poor old Badger, in his
secretive way, kept an eye on him, and probably shadowed him a bit too
openly. Then Hornby got alarmed and, in his turn, shadowed Badger, and
finally enticed him into that first-class carriage with the cigar all
ready in his pocket. But, if you knew, Doctor, why on earth didn't you
tell me?"

"My dear Miller," protested Thorndyke, "of course I didn't know in time
to prevent the prosecution. I have only just completed the case."

"By the way, Doctor," said Miller, "I suppose I can take it that there is
no mistake this time? You are quite sure of your man?"

"I am prepared to sign a sworn information," Thorndyke replied, "and I
will undertake to present a convincing case for the prosecution.
Naturally, I cannot promise a conviction."

"Of course you can't," said Miller. "But a sworn information from you is
good enough for me, to start with. We can go into the evidence another
time. But I am hanged if I know how to go about looking for the beggar. I
suppose you have no idea what he looks like nowadays?"

"I can only guess," replied Thorndyke. "We can safely assume that he has
not red hair or a red nose. Probably he has shaved off his beard and
moustache, and, judging from what Badger told you and from the fact that
he has certainly worn a wig when personating Dobey, it is likely that he
habitually wears a wig of a colour different from the lightish brown of
his own hair. But I must admit that those assumptions are not very
helpful. Still, you have the finger-prints that I handed to you, so, if
you make an arrest on suspicion you will know, at once, whether you have
or have not got the right man. And now let us dismiss this case, and have
a few words about another one that we want you to help us to work at."

Here Thorndyke gave the Superintendent a brief outline of the mystery of
Hartsden Manor House, dwelling principally on the testimony of the
servants and, characteristically, keeping his own counsel about the
"Automatic Watcher." Consequently, Miller, though deeply interested, was
a little disposed to be sceptical.

"It sounds a tall story," he remarked, "though it is by no means
impossible. At any rate, it is worth looking into. Of course, if a party
of crooks have managed to get in there, they have got ideal premises for
some kinds of jobs. Just think of a bank-note forger, for instance,
getting the use of a set of sealed rooms where he could work in perfect
safety, and leave all his incriminating stuff about with the certainty
that no one would stumble on it by chance! Or a maker of bombs, or any
other kind of illicit artisan. Yes, I certainly think it is worth looking
into. And you think the sportsmen are likely to turn up to-morrow night?"

"That is merely a matter of probability," said Thorndyke. "Apparently,
the visitor or visitors keep to regular days for their calls, and Friday
is one of those days. So we shall take the chance and spend the night
there. I think you had better come, Miller," he added, persuasively "Even
if nobody turns up, it will be worth your while to look over the
premises. You may be able to spot something that we might miss."

"I don't think you are likely to miss much, Doctor," said Miller, with a
faint grin. "However, I'd like to come with you; in fact, the more I
think of the job, the more it takes my fancy. There are all sorts of
possibilities in it. But, if you don't mind, I think I will bring a
couple of spare men, or let them come on later. You see, we may want to
post them in some cover outside, in case our sportsmen should happen to
spot us first and nip off. They would know the place better than we
should, and they might easily get away while we were trying to find the
way out. In that case it would be very handy to have a couple of men
outside who could hear the alarm and pounce on them as they came out."

We both agreed heartily to this excellent arrangement; and, when we had
discussed a few further details and settled the time for starting in the
morning, Miller lighted a fresh cigar and took his departure quite
revived in spirits by the prospect of the morrow's adventure.

Chapter XV: The Breaking of the Seals

DURING our journey down to Hartsden on the following morning,
Superintendent Miller's state of mind seemed to alternate between a
rather extravagant optimism and a haunting fear of an anticlimax that
might expose him to the derision of his subordinates. And such was his
condition when we introduced him to Mr. Woodburn at Hartsden Station.

"Well, sir," said he, "this is a very remarkable affair--if it isn't a
mare's nest. I hope it isn't."

"I rather hope it is," replied Woodburn, "though that is not my
expectation. But we shall soon know."

He held open the door of the car, and, when we had taken our places, he
drove off at a smart pace and soon covered the short distance between the
station and the Manor House. There, at the open door, we found Mrs.
Gibbins awaiting us, supported by Polton, who seemed to have established
himself as the master of ceremonies, and who conveyed to Thorndyke, in a
conspiratorial whisper, that the "Automatic Watcher" had been removed and
put out of sight. Evidently, he did not intend that his patent should be
infringed by the official investigators.

"We may as well go straight to the gallery," said Woodburn. "I've got the
key. Shall I show the way?"

Without waiting for an answer, he passed through the narrow doorway that
led into the corridor and the rest of the party followed, with the
exception of the housekeeper, whose good manners were even greater than
her curiosity, and who contented herself with a wistful observation of
our departure, following us with her eyes until we were lost in the
darkness of the corridor.

"Now," said Woodburn, as we drew up before the massive door of the
gallery, "we are going to clear up the mystery, if there is one. And, if
there isn't, we are going to catch it from Mr. Toke. At any rate, here
goes."

He opened his pocket knife and deliberately cut the stout tape that
connected the two seals. Then he inserted the little flat key into the
modern lock, grasped the handle of the door, and turned them both
together. The door moved slightly, far enough to disengage both the
latches, but no farther. He gave one or two vigorous pushes and then
looked round at us with a somewhat mystified expression.

"This is very odd," said he. "The door is free of the latches, but it
won't open. There seems to be something inside preventing it."

The Superintendent laid his large hand on the door and gave a hearty
shove. But still the door refused to move more than half an inch.

"Rum," said he. "Doesn't feel like a solid obstruction. There's a
distinct give in it. Shall I throw my weight against the door?"

"Better not," said Woodburn. "There's a flight of steps on the inside."

Here Polton's voice was heard enquiring meekly if it wouldn't be better
to lever the door open.

"Certainly it would," replied Miller, "if you know where to find a
lever."

"I happen to have a case-opener in my pocket," said Polton, in the
matter-of-fact tone of one announcing the possession of a lead pencil or
a fountain pen. "I think it would answer the purpose."

"I expect it would," Miller agreed, casting an inquisitive glance at our
versatile artificer. "At any rate, you may as well try."

Thus encouraged, Polton advanced to the door and unblushingly produced
from a long inside pocket a powerful telescopic jemmy of the most
undeniably felonious aspect. Quite unmoved by the Superintendent's stare
of astonishment, he first felt the door critically to locate the point of
resistance, and then, skilfully insinuating the beak of the jemmy into
the rebate of the door-jamb, gave a firm wrench at the long handle of the
lever. Immediately, there came a bursting sound from within, and the door
swung open, disclosing a short flight of steps leading down to the
gallery floor.

The Superintendent tripped down the steps and turned to look for the
obstruction.

"Well, I'm jiggered!" he exclaimed. "Your Mr. Toke is a cautious man with
a vengeance! He isn't taking any risks. Just look at that."

He pointed to the door-post, on which was a large seal, and, depending
from it, a length of strong tape with a mass of sealing-wax adhering to
its free end. We came down the steps and stood gazing at this singular
phenomenon while Miller swung the door round and exhibited, near its
edge, the broken seal from which the tape had torn out.

"Now, why the deuce," demanded Wilier, "should he have wanted to seal the
door on the inside? And when he had done it, how the devil did he get
out?"

"Exactly," said Thorndyke, "that is what interests us. This inside seal
gives a conclusive answer to our principal question. He couldn't have got
out by this door, so there must be some other way out. And a way out is a
way in."

"M'yes," Miller agreed in a reflective tone. "That is so. But it seems to
raise another question. Is it quite certain that Mr. Toke has really gone
abroad? Is it certain, for instance, that he is not just keeping out of
sight for some private reasons?"

"Of course," Woodburn replied, a trifle stiffly, "there is no absolute
proof that he has gone abroad. But he said that he was going abroad; he
locked and sealed his premises, and was seen thereafter to go away from
his house. He put his car into storage, and he has not since been seen in
any of his usual places of resort. I may say further that he is a
gentleman of the highest character and repute, and that I can imagine no
reasons that should induce him to keep out of sight."

"Then," said Miller, apologetic--but unconvinced, as I suspected--"that
settles it. You must excuse me, Mr. Woodburn, but I did not know Mr.
Toke. We shall have to look for some other explanation. Probably we shall
find it when we have made our examination of the premises; when we have
ascertained, for instance, whether there is anything missing. Shall we
take a look round and check the property? I suppose you know roughly what
there was in these rooms when Mr. Toke went away?"

"Yes," replied Woodburn; "I think I should know if anything of value had
been taken away."

With this, Miller and the solicitor proceeded to make a systematic tour
of inspection, passing along the range of wall--cases and rapidly
glancing at the objects on the shelves and apparently finding the
collection intact.

"It's rather queer, you know," said Miller, when they had made the round,
"that none of these things should have been taken. I imagine that they
are pretty valuable pieces."

"They are," replied Woodburn, "but they wouldn't be much use to a thief,
seeing that they could be so easily identified; at least, that was Mr.
Toke's opinion. He always considered the collection quite safe, so far as
burglars were concerned."

"To a certain extent he was right," said Miller. "This stuff would be no
use to an ordinary burglar if there was a hue and cry and a description
of the stolen property. But that doesn't apply to the present conditions.
If someone has been entering these rooms, he might have taken the whole
boiling away and have offered it quite safely at a common auction, in
small lots at a time. Because, you see, nobody would have known that it
had been taken. And there's plenty of demand for this sort of stuff. What
is in this room?" he added, as their peregrinations brought them to a
door near the entrance.

"That is where the collection of bronzes is kept," replied Woodburn. "We
may as well see if they are all right, too."

Thereupon, he opened the door and entered the room with the
Superintendent.

Meanwhile, Thorndyke had been devoting his attention to the seals on the
gallery door, making a minute comparison of the outside seal with that on
the inside door-post. As Miller and the solicitor disappeared into the
adjoining room (closely attended by Polton, who was apparently determined
that the Superintendent should not steal a march on his employer),
Thorndyke handed me his lens, remarking:

"The seals appear to be identical. I should say that they were both made
with the same matrix."

"Is there any reason why they should not be?" I asked in some surprise.

"No," he replied, "I don't think there is." I made a somewhat perfunctory
comparison--for Thorndyke's opinion was good enough for me--and then
remarked:

"I am in the same case as Miller. I can't imagine what object Toke can
have had in sealing the inside of the door. Do you understand it?"

"Not if the seals were affixed by Toke," he replied; "seeing that Toke
had access to the whole of the house and could examine the sealed door
from the outside to satisfy himself that the seals were intact. But it
would be quite understandable if the inside seals were fixed by someone
who had not access to the house, but who would wish to be assured that
the outside seals had not been broken. Supposing, for instance, there had
been no inside seals, and supposing that we made our inspection without
disturbing anything and went away, locking the door behind us. There
would be no trace of our visit, nor any evidence that the rooms had been
entered. But now, if we should go away and our friends should return
to-night, they would see at a glance that someone had been here, and, no
doubt, they would discreetly clear off and abandon their tenancy."

"Yes," said I. "That seems to be the explanation. It had not occurred to
me, nor, apparently to Miller. But there is another point. If the
visitors sealed the door on the inside, they must be in possession of the
seal."

"Obviously," he agreed. "That is the important  point. If it is a fact,
it is an extremely significant fact, especially when it is considered in
connection with a certain 'Ginger Lushington.'"

At this critical stage, our conversation was interrupted by the
Superintendent's voice, hailing us from an adjoining room. At once we
hurried into the room which we had seen him enter, but, finding it empty,
passed through into a second room, with which it communicated, and so, by
another communicating doorway, into a third. This also was empty, save
for a company of bronze statuettes on its shelves, but, through the
farther doorway, we could see into a fourth, larger room, and thither we
made our way.

As we entered, I looked round me with no little surprise. The three small
rooms through which we had passed with their glazed wall-cases and rare
and curious contents, had the trim, well-kept aspect of an art museum.
This fourth room presented a startling contrast. Considerably larger than
the others, it had the appearance of a goldsmith's or metal-worker's
workshop. In one corner was a large, rectangular chemical sink, and,
adjoining it a fixed wash-hand basin. At one side was a massive
crucible-furnace, arranged to burn charcoal and fitted with a
foot-bellows. Close by was a massive post, fitted with a flat stake and a
jeweller's "sparrowhawk." There were one or two cupboards and enclosed
nests of drawers, and a strong bench provided with a serviceable vice.
These details my eye took in rapidly, but there was no time for a
complete survey, for my attention was instantly riveted on an object on
the bench round which our three friends were gathered in a mighty ferment
of excitement.

"Here's a discovery, if you like, Doctor!" the Superintendent exclaimed,
gleefully. "You remember my telling you about those bogus sovereigns?
Well, we've struck the sovereign factory! Just look at this!"

He indicated the object on the bench--which I now recognized as the box
that I had seen through the keyhole periscope, resting on the gallery
table, and that had been shown in the "Tuesday" photograph.

Polton's diagnosis had been correct. It was a casting box, or "flask,"--an
iron frame in two halves, held together in position by pins and eyes
at the sides. The upper, or pin, half had now been lifted off, and the
mould which filled the interior was displayed. And a very remarkable
mould it was, and very illuminating as to the kind of industry that was
being carried on in this room. In the smooth, flat surface of the matrix
were twenty sunk impressions of sovereigns, each beautifully clear and
shiny with graphite. The impressions were connected with one another, and
with the "pour" or inlet of the mould, by a deep groove, which was
one-half of the channel along which the molten metal was conducted to the
impressions.

"Quite a workmanlike outfit," chuckled the delighted Superintendent.
"Don't you think so, Mr. Polton?"

Polton crinkled approvingly. "Yes, sir," he replied; "and he knows how to
use it. He's no amateur. That is a wonderfully good matrix; hard enough
to stand brushing with graphite, and to be used over and over again. I
should like to know what it is. There's bone-ash in it, but there's
something else on the surface."

"Well," said Miller, "that's more interesting to you than to me. Let us
have a look at that other flask."

He indicated a second, similar flask that had been pushed to the back of
the bench. Reaching out, he drew it forward and passed it to Polton, who
tenderly lifted off the top half and turned it over, laying it beside the
lower half and thus exhibiting the two halves of the mould. As he laid it
down, he bestowed a crinkly leer on the Superintendent.

"Well, I'm jiggered!" the latter exclaimed. "Half-crowns, too! But I
always suspected that the half-crowns and the sovereigns were made by the
same man. It was the same idea in both cases. But now we have got to find
out where the stuff came from--where he kept his bullion, I mean. We had
better go through these cupboards and drawers."

He gave a lead by throwing open a deep cupboard, and, as the door
swung out, he uttered the single word, "Moses!" The relevancy of
the exclamation was not obvious, but the cause was extremely so.
For the deep shelves were occupied by an assemblage of silver
articles--candle-sticks, tea-pots, spoons, and the like, mostly a good
deal battered, and many of them reduced to small fragments, apparently
by means of shears. A second cupboard made a similar sinister display,
though the quantity was smaller. But of gold there was no trace.

"He must have kept his gold in the drawers," said Miller. "He couldn't
have brought it with him."

"He brought some of it with him, sir," said Polton, who had
been pulling out the drawers of a nest and peering in with a
school-boy's delight in a treasure-hunt. "Here is a piece of fine
gold plate--twenty-four carats--which certainly came from a bullion
dealer's."

At this report, Thorndyke, who had hitherto maintained the attitude of a
mildly interested observer, suddenly woke up. Taking a pair of pliers
from the bench, he went to the drawer which Polton was holding open and
carefully lifted out the piece of plate. Having scrutinized it closely on
both sides, he held it out for Miller's inspection.

"You had better secure this," said he. "There are some fairly clear
finger-prints on it which may be helpful later on, if our friend should
fail to keep his appointment to-night."

The Superintendent took the pliers from him, and examined the gold plate,
but with less enthusiasm than I should have expected. However, he laid it
carefully on a shelf of the cupboard, and then returned to the quest in
which he appeared to be specially interested. By this time Polton had
made some further discoveries that seemed more relevant, one of which he
announced by pulling a drawer out bodily and placing it on the bench.

"Sovereigns, by gosh!" exclaimed Miller, as he looked into the drawer.
"Now, I wonder whether these are some of the castings, or the originals
that he worked from. What do you think, Doctor?"

Thorndyke picked out one of the coins and examined its edge through his
lens, turning it round and inspecting the whole circumference.

"I should say that this is certainly genuine," he reported. "There is no
trace of the edge tool. The milling is quite perfect, and it seems to
show slight traces of wear. Moreover, the number--there are about two
dozen in the drawer--is not more than would be required as models to
avoid repetition of a particular coin."

"Yes, I expect you are right," said Miller, "but they will know at the
Mint, in any case. Ah!" he exclaimed, as Polton laid another drawer on
the bench. "This looks more interesting. No bullion dealer's stuff this
time, I fancy."

The drawer contained about a dozen small ingots of gold, each marked by
means of a punch with a number--presumably the carats of "fineness." One
of these Miller took up and held out for Polton's inspection.

"No, sir," said the latter, "that did not come from a dealer. It was cast
in that ingot mould on the shelf, there."

As he spoke, he took the mould down from the shell and slipped the ingot
into it, when it was seen to fit with quite convincing accuracy.

The Superintendent regarded it with profound attention for some moments.
Suddenly he turned to Polton and asked impressively:

"I want you to tell me, Mr. Polton, which of these things might have been
brought here by an outsider and which must have been put here by Mr.
Toke. There is this gold plate. That must have been brought here. But
what was it brought for?"

"To melt down with these ingots," replied Polton, "to bring the gold up
to 22 carats. The ingots are all 18 carats or less."

"But why couldn't he have used that acid process that you spoke of?"

"Because he would have had to cut up the ingots and hammer the pieces out
thin on the stake. But, if he had done that at night, they'd have heard
him all over the house. Besides, the fine gold plate would be quicker and
less trouble, and it would come to the same thing. He would get his money
back. As to what you were asking, I should say that the whole outfit of
this place must have been put here by Mr. Toke. The furnace certainly
was, and the crucibles and ingot moulds seem to belong to it; in fact, it
is a regular metal-worker's shop."

"And what do you make of those ingots?"

Polton crinkled knowingly. "I think, sir," he answered, "they are more in
your line than mine. They are not trade ingots, but they are about the
fineness of good-class jewellery."

At this point, Thorndyke, who had been listening with rather detached
interest to this discussion, sauntered out into the gallery, leaving
Polton and Miller to their devices.

"I think," said he, as I followed him out, "we had better get on with our
own job. This coining business is no concern of ours."

With this, he went along to the entrance door, on the steps of which he
had left his research case, and, picking it up, carried it back to the
table and deposited it thereon.

"We may as well begin with the most obvious probabilities," said he, as
he opened the case and ran his eye over the contents. "I suppose you
noticed this end of the room, as it showed in the photograph?"

I had to admit that I had not taken especial note of it, nor did I now
perceive anything particularly striking in its appearance. The end wall
was decorated pleasantly enough, by a low elliptical arch of simply
moulded oak supported by a pair of oaken pilasters, the surfaces of which
were enriched with shallow strap carving in the form of a guilloche with
small rosettes in the spaces. There was nothing remarkable about it; and,
to tell the truth, I was not quite clear as to what I was expected to
see. And Thorndyke's proceedings enlightened me not at all.

"The police methods are good enough for our present purpose," he
remarked, as he took out a wide-mouthed bottle and a large camel-hair
brush. "The good old Hyd. cum-creta."

Removing the stopper from the bottle, he picked up the latter and the
brush, and walked across to the pilaster nearest the window. Dipping the
brush into the bottle of powder, he began to paint it lightly over the
carved surface. I watched him with slightly bewildered curiosity; and,
looking through the door way into the workshop, where I noticed Woodburn
listening with an anxious and rather disapproving expression to the
comments of our assistant and the Superintendent, I perceived that the
two latter had developed a sudden interest in my colleague's activities.
Presently Miller came out for a closer inspection.

"I thought you always used a powder-spray," he remarked. "And you needn't
worry about finger-prints. Those on the gold plate will tell us all we
want to know. And," he added in a lower tone, "let me give you a hint.
Your nocturnal stranger is a myth. The name of the chappie who runs the
sovereign factory is Toke. Mustn't say so before Woodburn, but it's a
fact. It stares you in the face. Mr. Toke is a fence. Dam' clever fence,
too. Buys the scrap from the jewel-robbers, sells the stones, and melts
down the settings into sovereigns. I take my hat off to him, and I only
hope he'll turn up to-night and let me have the pleasure of making his
acquaintance."

Thorndyke nodded, but continued to brush the grey powder on to the
woodwork in a broad band from near the floor to a little above the eye
level. The Superintendent watched him with a slightly anxious expression,
and presently resumed: "I don't see why you are so keen on finger-prints,
all of a sudden, or why you should expect to find them in this
particular and rather unlikely place. At any rate, there don't seem to
be any."

"No," said Thorndyke, "we seem to have drawn a blank. Let us try the
other side."

He crossed the room and began operations on the second pilaster, watched,
not only by Miller, but also by Polton and Woodburn. But this time he did
not draw a blank, for, at the first sweep of the brush, the pale-grey of
the powder was interrupted by a number of oval shapes, forming an
irregular, crowded group close to one side of the pilaster about four
feet above the floor. Thorndyke blew away the superfluous powder and
examined the group of finger-prints closely. It seemed to be divided into
two subgroups, one on the extreme edge of the pilaster and extending
round to the side, and the other in the space of one member of the
guilloche, around and over the enclosed rosette. After another close
inspection, Thorndyke grasped the marked rosette between his fingers and
thumb, and tried if it were possible to rotate it. Apparently it turned
quite easily; but, beyond the rotation, no result followed. After a
moment's reflection, Thorndyke took a fresh hold, and gave it another
turn in the same direction. Suddenly, from within, came a soft click; and
then the whole shaft of the pilaster, from the capital to the plinth,
swung out a couple of inches like an absurdly tall and narrow door.
Thorndyke grasped it by the edge and drew it fully open, when there came
into view a small triangular space of floor and a low, narrow opening at
the side, with the beginning of a flight of ladder-like steps, the end of
which was lost to view in the impenetrable darkness of a passage which
seemed to burrow into the substance of the wall.

"Well, I'm jiggered!" exclaimed Miller. "Now, I wonder how you guessed
that door was there, Doctor?"

"I only guessed that it might be there," said Thorndyke. "Hence the
search for finger-prints. Without them, we might have spent hours trying
to find the secret door, and especially the fastening, which was so
cleverly concealed. However, we have solved the most difficult part of
our problem. The outside opening of this passage is probably as cleverly
hidden as the inside one. But it will be hidden from without, whereas we
shall approach it from within, where there is probably no concealment."

"I suppose it is worth while to explore that passage," said Miller,
looking a little distastefully at the narrow, black chink, "though,
really, we want to know who the man is, not how he got in."

"Perhaps," replied Thorndyke, "an exploration of the passage may answer
both questions. At any rate, Mr. Woodburn will want to know how the house
was entered from the outside."

"Certainly," Woodburn agreed. "That was, in fact, what we came to find
out."

As Thorndyke produced from his case a couple of powerful electric
inspection lamps, one of which he handed to me, I reflected on his
slightly cryptic answer to the Superintendent's question; as also did
Miller himself. At least, so I judged from the inquisitive look that he
cast at Thorndyke. But he made no remark; and, when he had provided
himself with an electric lantern from his bag, he announced that he was
ready for the exploration.

Thereupon, Thorndyke turned on his lamp, and, squeezing through the
narrow opening, began to descend the steps, followed, at due intervals,
by the rest of the expeditionary party.

Chapter XVI: The Vault

IN the course of my descent of that interminable stairway, I found myself
speculating curiously on the physical characteristics of the dead and
gone Greenlees. They must, I decided, have been a thin family; for,
surely, no corpulent person, no matter how hard pressed or how deeply
embroiled in political machinations, could ever have got down those
steps. Vainly did I seek to avoid contact with those slimy,
fungus-encrusted walls. They pressed in on me from either side as if I
had been sliding down a tube. Not, indeed, that this close contact was
without its compensations, for, since there was no hand-rail, and the
steps were incredibly steep and narrow, and, like the walls, slippery
with slime and fungus, it gave some slight feeling of security.

But it was a hideous experience. Soon the faint glimmer of daylight from
the doorway above faded out and gave place to the ghostly light of the
electric lamps, which glanced off the shiny, unsavoury walls and ceiling
in fitful gleams that dazzled rather than illuminated. Moreover, the air,
which at first had seemed only musty and close, grew more and more foul,
and pervaded by a strange, cadaverous odour unlike the usual earthiness
of underground cellars and passages.

At length, the sudden eclipse of Thorndyke's lamp, followed by that of
Miller's, and a faint reflection on the wall, told me that they had
turned into some other passage. Then I, bringing up the rear, reached the
bottom of that apparently endless flight, and found myself on a small
paved space from which opened a low tunnel along which my predecessors
were creeping in postures more suited to chimpanzees than to
representatives of the law. I lowered my head and shoulders and followed,
concentrating my attention on avoiding contact with the unclean ceiling.
Presently Miller's voice came rumbling unnaturally along the tube-like
passage.

"What does your compass say, Doctor? Which way are we travelling?"

"Due west," was the reply. "Towards the church." I had hardly time to
consider the significance of this piece of information when the
Superintendent's voice again rang out, this time in a slightly startled
tone:

"Why, this is a vault!"

A few moments more, and I was able to confirm the statement. The tunnel
ended in a narrow, oblong chamber, barely three feet wide, but more than
a dozen feet long, and of a height that, at least, allowed one to stand
upright. I availed myself of this advantage, and looked around me with
some curiosity and a strong desire to find the way out. For, if the air
had been foul on the stairs and in the tunnel, it was here suffocatingly
fetid.

The light of the three powerful lamps made it easily possible to see all
the details of structure and arrangement. And a strange and gruesome
place it looked in that lurid illumination; a long, passage-like chamber,
as I have said, paved with stone and enclosed with walls of damp and
slimy brick. At the ends, the walls were solid, excepting the arched
opening of the tunnel, but the long side walls were each interrupted by a
widish arch which opened into a side chamber. Both chambers were fitted
with massive stone shelves, something like the bins of a wine-cellar, and
on these could be seen the ends of the coffins containing, presumably,
mature specimens of the Greenlees vintage. Above, at a height of about
ten feet, the long walls supported what looked like a bottomless
brickwork box about eight feet long, the rest of the chamber being roofed
in with stone slabs. Under the box, towards one end, a thick iron bar--or
what would nowadays be called a girder--crossed the chamber and
supported at its middle an upright iron post that seemed to be fixed into
the top of the box.

But the feature that interested me most was a flight of steep and narrow,
but perfectly practicable, brick steps, which started from the mouth of
the tunnel and passed up the left-hand wall above the arch to the base of
the box near the end opposite to that which was crossed by the iron bar.

"I don't quite understand that contraption up there," said Miller,
throwing the light of his lantern on the under-side of the box, "but
there's a flight of steps, so I suppose there's a way out; and I propose
that we try it without delay. The atmosphere of this place is enough to
stifle a pole-cat."

"We mustn't be precipitate, Miller," said Thorndyke. "We want to find the
way out, but we don't want to publish it to the world at large. Before we
go out, we must send someone up to see that the coast is clear."

"I suppose we shall be able to get out," said Woodburn, "though I don't
see very clearly how we are going to do it. But I expect you do, as you
nosed out that doorway so readily."

"I think it is pretty obvious," replied Thorndyke. "That coffer-like
structure up there I take to be the Greenlees tomb in the churchyard. The
top slab seems to rotate on that iron pivot and those curved runners that
cross on the under-side. But I will run up and make sure of it before we
send out our scouts."

He climbed cautiously up the brick steps, and having reached the top,
threw the light of his lamp on the under-side of the slab and examined
the simple mechanism.

"Yes," he reported, "I think it is all plain sailing. The runners are
clean and smooth, and both they and the pivot have been kept well oiled.
It won't do to try it, in case there should be anyone in the churchyard.
Now, who is going up as scout? I suggest that you go, Woodburn, as you
know the tomb; and the Superintendent had better go with you to learn the
lie of the land. Take a stick with you, and, if it is all clear, give
five distinct taps on the side of the tomb; and be careful not to leave
any more tracks than you can help."

Neither of the scouts showed any reluctance. On the contrary, they both
assented with a readiness that I attributed to the influence of the
deceased Greenlees. At any rate, they waited for no further instructions,
but dived forthwith into the tunnel, whence presently came the echoes of
their footsteps as they scrambled up the steps towards the fresh air and
the light of day.

As they disappeared, Thorndyke began a systematic exploration of the
vault, throwing the light of the lamp into all the darker corners and
finally extending his researches into the side chambers.

"Isn't it rather odd," said I, "that the air of this place should be so
extraordinarily foul? I take it that there have been no recent burials
here."

"If the inscriptions are to be accepted," he replied, "the last burial
took place more than sixty years ago. I agree with you that the physical
conditions do not seem to be quite consistent with the inscriptions.
Perhaps we may find some explanation."

He walked slowly round the first chamber that he had entered, throwing
the light on the shelves and examining, the latter with minute and
suspicious scrutiny, reading each of the coffin-plates, and inspecting
each coffin critically as to its condition. Having made his round of the
first chamber, he crossed to the second, followed by me and Polton--who
had developed a profound and ghoulish interest in the investigation. He
had passed along nearly the whole length of the first shelf when I saw
him stop and look closely, first at the shelf, then at the ground beneath
it, and, finally, at the two adjacent coffins.

"This wants looking into, Jervis," said he. "These two coffins have
been moved quite recently. The thick dust on the shelf has been brushed
away--you can see some of it on the floor--but there are clear traces
showing that both coffins have been pulled forward. And, if you look
closely at the coffins themselves, you will see pretty evident signs of
their having been opened at some fairly recent time. This right-hand
one has been opened quite roughly, with inadequate tools. The other
has been treated more skilfully; but if you look at the screws you can
see that they have been withdrawn and replaced quite recently. Parts of
the slots have been scraped bright by the screwdriver and the edges of
the slots are burred up, particularly on the left side, showing that
they were difficult to turn, as you would expect in the case of an old
screw that has been in position for years."

"For what purpose do you suppose the coffins were opened?" I asked.

"'Why suppose at all?" he replied, "when the coffins are here, and Polton
has a whole burglar's outfit on his person? Let us get the lids off and
see what is inside. I take it that the damaged coffin is the one that was
opened first, so we will begin with the other one. Have you a
practicable screwdriver about you, Polton?"

The question was hardly necessary, for Polton had already extracted from
some secret and illegal pocket a good-sized ratchet screwdriver with a
hollow handle containing several spare blades of different sizes. Having
taken a glance at the screws, he fitted in a blade of the appropriate
size, and then, as we drew out the coffin to the front of the shelf, he
fell to work on it.

"The last operator wasn't much of a hand with the screwdriver," he
grumbled. "He's scraped away half the slots."

However, by bearing heavily on the tool, he got the screws started, and,
as they came out one by one and were put tidily on a clear space on the
shelf, we brought the coffin a stage farther forward to bring the next
one within reach. When the last of them had been extracted, the
"case-opener" was produced, and its beak inserted under the lid. A slight
tweak raised the latter, and it was easily lifted off.

As Polton drew it aside and exposed the interior of the coffin, I uttered
a cry of astonishment.

"Why, there are two bodies!" I exclaimed.

"Skeletons, I should call 'em, sir," Polton corrected, disparagingly.

"Yes," Thorndyke agreed; "there would hardly have been room for two
recent corpses. But they are not so badly preserved, considering that
they have been here for close on a century. Now, let us get the other one
open, and don't damage the coffin more than you are obliged to, Polton."

"Am I right," I asked, "in supposing that you expected to find two bodies
in that coffin?"

"Yes," he replied. "That was what the circumstances seemed to suggest."

"And what do you expect to find in the other one?"

"That question, Jervis," said he, "seems to be answered by the one that
we have just opened. Why should a man take a body out of one coffin and
cram it into another which is already occupied?"

The answer was certainly pretty obvious. But the discussion came to a
premature end: for, in spite of Polton's care, the damaged lid came loose
before all the screws had been extracted. As he lifted it off, I threw
the light of my lamp into the cavity; and though it disclosed nothing
that I had not expected, I stood for a while, silently gazing into the
coffin with horrified fascination.

The bright glare of the lamp fell on the figure of a grey-haired man,
fully clothed, even to a crumpled soft felt hat. His age, so far as it
was possible to judge, appeared to be from fifty to sixty, and his neat
worsted clothes and the quality of his linen suggested a man of some
means, reasonably careful of his appearance. As to how he had died there
was nothing to show, save for the sinister suggestion of a smear of blood
on one sleeve. I was just turning to Thorndyke to ask a question when the
deathly silence was broken by five sharp taps from above, which
reverberated through the vault with quite startling distinctness.

"There is Woodburn," said Thorndyke. "Lay the covers on the coffins."

With this he picked up his lamp and went out into the main vault.
Following him, I saw him pick his way carefully up the steep and narrow
steps until he reached the little platform at the top. There he paused,
and threw his light on the under-side of the covering slab. Then,
grasping what appeared to be some sort of handle, he gave a pull, first
downward and then sideways. Immediately the heavy slab turned on its
pivot and runners with a dull grinding sound and a stream of brilliant
daylight poured down into the gruesome interior. A moment or two later it
was partially obscured as Miller and Woodburn leaned over the edge and
peered down curiously into the vault.

"Is it necessary for us to come down again?" Miller enquired. "The air is
a good deal fresher up here."

"I shall want Mr. Woodburn to come down," said Thorndyke. "We have been
making some investigations, and I should like to have his opinion on
something that we have discovered. Probably you will be interested too."

He was--very decidedly. At the mention of a discovery, his long legs
swung, one after the other, over the edge of the sarcophagus, and he
followed Thorndyke down the steps as rapidly as was consistent with the
necessary caution. Close behind him came Woodburn, all agog with
curiosity.

"It isn't so bad here," he remarked, "now that we have got that cover
open. We had better keep it open, and let a little air in."

"Then," said Thorndyke, "Polton had better go up and keep a look-out. We
don't want any other observers. You saw how the slab was moved, Polton.
If anyone comes in sight, shut it at once."

I could see that this duty was not at all acceptable to our ingenious
coadjutor, who evidently foresaw dramatic developments in the immediate
future. Nevertheless, he climbed the steps and thrust his head out of the
opening. But I noticed that one eye and both ears were kept focused on
the happenings down below.

"Now, Doctor," said Miller, "what is this discovery that you have made?"

"I will show you," said Thorndyke, leading the way into the side chamber.
"But I may explain that we found that two of the coffins had been moved,
and moved quite recently. But they had not only been moved: they had been
opened and reclosed. On observing that, we thought it desirable to open
them and ascertain why they had been opened. We did so, with this result:
we found in one coffin two bodies--two quite ancient bodies; mere
skeletons, in fact."

"Then," said Woodburn, "you may take it that they are strangers to me,
and they are not any concern of mine. So we will take them as read."

"Very well," said Thorndyke. "I will not trouble you with that coffin.
But I must ask you to look at the other. This is the one."

He drew the coffin a little farther to the front of the shelf and lifted
off the lid, throwing the light of his lamp into the cavity. Mr. Woodburn
approached with very evident reluctance, holding his handkerchief to his
face, and cast a glance of mingled disgust and apprehension towards the
coffin. Suddenly he stopped and then started forward with a
half-articulate cry. For a moment he stood staring with incredulous
horror. Then, in a voice tremulous with emotion, he exclaimed:

"Great God! It's Mr. Toke!"

For some moments there was a dead silence. Then Thorndyke replaced the
coffin lid, and we went back to the main vault. And still, for a while,
no one spoke. On Woodburn this revelation had fallen like a thunderbolt,
while Miller, whose theory of the criminal doings at the Manor House was
suddenly shattered, was wrapped in the most profound cogitation. At
length the latter broke the silence.

"How long do you think Mr. Toke has been in that coffin, Doctor?" he
asked.

"I should say," replied Thorndyke, "that he has been there ever since the
day on which he was supposed to have gone abroad."

"Yes," said Woodburn, "I think you are right. I have had all along a
lurking suspicion that he never really went abroad; that something
happened to him on that last day. I didn't at all like the garage man's
story of that ginger-haired fellow with the red nose."

"Eh!" exclaimed Miller, all agog in a moment. "What story was that?"

Woodburn gave him a brief summary of the incident of the returned car and
the "Ginger Lushington," to which he listened with profound attention,
and on which he cogitated for a while when Woodburn had finished.
Suddenly he turned to Thorndyke, and regarded him eagerly and almost
fiercely.

"Now, look here, Doctor," said he, "you have got to tell us what all this
means. It is no use for you to try to put us off. You hold all the clues
and you know all about it. You have followed this case as if you were
running along rails. You knew that someone had been here. I believe you
knew about those sovereigns, and you went for that secret door as if you
knew exactly where to look for it. And then you came down into this vault
and you went straight for that coffin. I have no doubt that you knew Mr.
Toke was there. Now, Doctor, I ask you to tell me who killed Mr. Toke,
and who was that red-nosed man."

"You are asking me," replied Thorndyke, "to make a statement, whereas I
can only offer an opinion. But you can have that opinion for what it is
worth; and I may say that I think it is worth a good deal, as it is based
on a mass of evidence. I should say that the red-nosed man at the garage
and the murderer of Mr. Toke are one and the same person; and that person
is named Walter Hornby."

"What!" exclaimed Miller. "The villain who murdered Badger!"

"That is what I believe," said Thorndyke. "But I hope that we shall have
the opportunity to settle the question. At any rate, we may fairly take
it that the person who has been frequenting these premises is the person
who murdered Mr. Toke."

"And you expect that person to come here to-night?"

"It is only a probability," replied Thorndyke. "You know our reasons for
expecting him. It may be to-night, or he may choose some other night. But
there is very little doubt that he will come sooner or later to finish up
the gold that is left, and take away those sovereigns. But it is quite
possible that the next visit will be meant to be the last."

"It will be the last," Miller remarked, grimly. "If I stay here till
Doomsday, I am going to have him."

There was a brief pause. Then Woodburn asked:

"Where and how do you suppose the murder was committed?"

"I should say," answered Thorndyke, "that the deed was done at the top of
those steps. There is what looks very much like a blood-stain on the
brick there. As to the circumstances, I should say that they were roughly
these: I take it that Mr. Toke, when he took the car out of the garage,
had for some reason to come down here, unexpectedly, to fetch something
from, or deposit something in, the gallery; and he had reasons for not
wishing to enter the house and break the seals. I think that the murderer
must have come to know of this intended visit, and have come on in
advance and waited for him in hiding somewhere; that he saw Toke arrive,
followed him into the churchyard, and saw him enter the tomb by the
secret opening. I suspect that he waited for him to come out, and then
murdered him as he was emerging from the tomb. Then he explored the
vault, hurriedly broke open a coffin, and, having disposed of the body,
made an inspection of the premises, the valuable contents of which may
have been known to him. At any rate, he would have found the gold, and
known then that it would be worth while to come back to take it away. I
should think that the sovereigns were probably an afterthought, suggested
by the quantity of gold bullion, which would have been rather unsafe to
dispose of in the regular way. Moreover, if I am right as to the identity
of the man, we must remember that he was an assayist by profession, and
would have an expert knowledge of the methods of dealing with gold. But,
as to that, we shall know more when we have seen him. And now we may as
well relieve Polton and get back to the house. I don't think we have left
any traces of our visit down here, and we must be careful to leave none
in the churchyard as we go out."

"No," Miller agreed fervently, "for the Lord's sake don't let us spoil
our chances by giving him any sort of warning. At present, we seem to
have him in the hollow of our hand. It would take ten years off my life
if we should let him slip."

"I don't think you need have any misgivings, Miller," said Thorndyke. "He
is bound to come back; and we are agreed that we are willing to wait for
him to come in his own time. We can only hope that he will not keep us
waiting too long."

Chapter XVII: The Vigil

WE made our way out of the vault, one by one, creeping cautiously up the
narrow brick steps, and climbing over the side of the tomb into the green
and sunny churchyard. Woodburn was the first to emerge, and, as he
stepped down on to the grass, he drew a deep breath.

"Lord," he exclaimed, "it is good to be back in the world of living men
and to breathe the fresh air. That was a horrible experience!"

I sympathized with him, though, naturally, my professional training had
made me less sensitive to merely physical unpleasantness. For I realized
that, whatever misgivings he might have had respecting his client, it
must have been a shocking experience to be brought suddenly, without
warning, face to face with his murdered corpse. Even Miller was not
unaffected by the tragedy that had been so abruptly sprung upon him.

Thorndyke was the last to come up, having lingered to take a final look
round and make sure that no tell tale evidence of our visit had been left
to arouse the suspicions of the hoped-for visitor. As soon as he had
stepped out, he seized the displaced slab, and, with a vigorous pull,
swung it round into its normal position.

"We may as well make sure, before we go," said he, "that we all
understand how this arrangement works from the outside. It seems to be
quite a simple device. The slab rocks slightly on its pivot. To release
the inside catch, the higher end of the slab has to be pressed down. This
raises the other end and so frees the catch. You see that, at present,
the slab is quite immovable; but when I throw my weight on this end, I am
able to swing it round without difficulty."

As he spoke, he demonstrated the mechanism; and when Miller had satisfied
himself by actual trial that he had fully grasped the method, we took our
way out of the churchyard and walked across to the house. There we were
admitted by Mrs. Gibbins in person, who informed us that two officers had
arrived, and, further, that lunch would be served in five minutes, and,
furthermore, that separate arrangements had been made for Mr. Polton and
the two officers.

At the latter announcement Miller smiled grimly. "Artful old puss," was
his comment, when she had gone. "Made her arrangements to have Mr. Polton
all to herself, and get the latest news. But it doesn't matter. She's an
interested party, and it will save me the trouble of giving my men the
particulars."

Nevertheless, he introduced us to the two officers, and gave them a few
instructions, and then we retired to remove, as far as was possible, the
traces of our subterranean activities, before sitting down to lunch.

It was a very leisurely meal; almost intentionally so; for there was
little more to do in the way of preparation, and a long interval before
the next phase of our adventure could be expected to begin. But there was
plenty of material for discussion, especially as Woodburn had to be put
in possession of the numerous and complicated antecedents of the case.
Then the details of the procedure to be adopted in the actual capture had
to be considered, and the course that would have to be taken in the event
of the quarry failing to appear. As to the former, Miller showed a
disposition to simplify the proceedings by making the arrest in the
churchyard.

"You see," he explained, "there's a good deal to be said for catching
your hare while you have the chance. If we collar him as soon as he has
gone up to the tomb, we shall make sure of him; whereas, if we let him go
down, he may disappear into some underground passage that we know nothing
about."

But Thorndyke shook his head very decidedly. "No, Miller," said he. "That
won't do. It is a bad plan in two ways. In the first place, the
churchyard is not secure enough. He would have quite a fair chance of
escape in that open space, with its various obstructions to dodge among,
and possibly a car waiting close by. In the second place, he ought to be
arrested, for evidential reasons, in the gallery. Remember that we have
got to identify him with the coiner who has used Mr. Toke's gold, and we
are going to charge him with the murder of Mr. Toke. Now, if you arrest
him in the churchyard, you have got those charges to prove. You will
infer, reasonably enough, that he has come into the churchyard for the
purpose of entering the house by way of the secret passage. But in a
criminal trial, on a capital charge, evidence is sifted very finely. The
defence would deny the intention, and you would have to prove it. But if
he is taken actually in the gallery, that fact is evidence in itself of
his connection with the coining, and, by fair inference, with the murder
of Mr. Toke."

Miller admitted the force of this contention. "But, still," he urged, "we
are not dealing with an unknown man. You say you can prove his identity,
which connects him with a previous crime, and you have got substantial
evidence in regard to the murder of poor Badger."

Thorndyke, however, was firm. "It won't do, Miller," said he. "We shall
want every particle of evidence that we can get. At present, all that we
have is circumstantial. But, with all respect to the dictum of a certain
learned judge, circumstantial evidence is much less satisfactory to a
jury than that which is more or less direct."

"Very well," said Miller; "you know more about court work than I do. But
what do you suggest--I mean, about planting my men?"

"The best plan, I think," replied Thorndyke, "would be to instruct them
to hide behind the yew tree--it must be pitch-dark there at night--and
to wait for the man to arrive. They should let him go down into the tomb,
and, as soon as he has disappeared, they should take up their stations at
the side of the tomb nearest the steps. There they would have absolute
control of him if he should come up again, as he would be standing on the
steps."

"You speak of 'him,'" Miller remarked. "Supposing there should be a
gang?"

"That is very unlikely," replied Thorndyke, "but, even so, there are four
of us, without counting Polton. I think we can take our chance. Are you
and your men armed?"

"No," replied Miller; "we don't much favour firearms in the force. We've
brought two or three sets of handcuffs, and, for the rest, we've got a
pretty serviceable outfit of fists."

"Well, I took the precaution to bring four automatics," said Thorndyke.
"You had better have one. A man who has two murders to his account is not
likely to boggle at one or two more."

Eventually, the Superintendent accepted Thorndyke's suggestions, and,
when we had finished lunch, the final preparations were made. Thorndyke
showed the two officers the secret door, and demonstrated the working of
the catch from outside and from within, and then conducted them down the
stair-way and through the vault to the opening, at which Polton had been
sent to keep a look-out. When they had mastered the working of the
movable slab, they were shown the spot behind the yew tree where they
were to keep watch later on. Then the whole party returned to the house
by way of the vault--to avoid exhibiting themselves to any chance
observers in the village.

When the officers had been dismissed to repose and smoke their pipes in
Mr. Toke's study, Thorndyke produced a six-inch ordnance map of the
district, and invited the attention of Woodbury and the Superintendent to
a narrow lane that appeared to run close beside the churchyard, and,
presently to open into a by-road at no great distance.

"It seems probable," said he, "that our friend, or friends, make the
journey here by car, unless they should be local persons; which is most
unlikely. And if they do, this lane would be an ideal approach, as it
would avoid the village street, and be a most convenient place in which
to leave the car--quite close to the churchyard and well out of sight.
It might be worth while to go and inspect that lane."

"I don't think that is necessary," said Woodburn, "because the same idea
had occurred to me, and I took the opportunity to walk along it this
morning. And I have no doubt that you are right. At any rate, someone has
been bringing a car up that lane, for there were clear traces of one--a
smallish car it seemed to be--especially at a place near the middle,
where it is wide enough to turn round. I could see quite plainly the
marks on the grass verge where he had backed in to turn. It appeared that
he entered the lane from the by-road and stopped short a couple of
hundred yards from the village street. So he must have gone back on the
reverse until he came to the wide part, and then have turned round and
gone out by the by-road."

"Were these the marks of a single journey," asked Miller, "or were there
more than one set?"

"At the wide part," answered Woodburn, "on the soft grass verge, there
were a number of tracks on top of one another. I couldn't say how many."

"Then," said Miller, "we needn't trouble to inspect it; which is as well.
The less we show ourselves in this neighbourhood the better. I'll tell my
men to keep their ears pricked up for the sound of a motor, though if it
is occupied by the parties that we are expecting, it isn't likely to be a
very noisy one."

"No," Thorndyke agreed; "but in the silence of the country at night it
will certainly be audible, especially if the driver should take the
precaution--as he probably would--to turn round as soon as he arrived,
so as to be ready to drive straight off in the event of an alarm. So we
will hope that he comes in style in his car. It would give a very useful
warning to your watchers."

"Yes," said Miller, "and it would be rather useful if they could pass the
warning on to us in some way. What do you think, Doctor?"

"Of course," replied Thorndyke, "it would be a great help to us. But I
think we shall have to do without it. Any kind of signalling would be
extremely unsafe. It might easily give a warning in the wrong quarter."

Miller acknowledged the truth of this, and the subject dropped. And then
began a somewhat tedious period of waiting; for there were yet several
hours of daylight to dispose of before our actual vigil would begin. The
Superintendent, being an old hand at this sort of business, retired to
the study to smoke and "take forty winks"; while Thorndyke, Woodburn, and
I whiled away the afternoon by making a complete tour of Mr. Toke's
collection.

A very remarkable collection it was. The gallery was filled mainly with
Bow, Chelsea, and other porcelain figures, while the three smaller rooms
were occupied by bronze busts and statuettes and a small collection of
choice pottery and enamels. The entire contents of the rooms must have
been of very great value, for all the pieces seemed to have been selected
with the most fastidious taste and obviously expert judgment, without
regard to cost. As we walked round and admired them one after another,
they suggested two rather curious questions.

First, was it credible that the man who had acquired and treasured all
these things of beauty, with such obvious enthusiasm and love for them,
could be a mere fence--a receiver of stolen property? Those ingots in
the workshop had certainly looked suspicious. Yet how could one believe
it? The man who had cherished all these beautiful things so lovingly was
no common money-grabber. Every one of them seemed to cry out in
vindication of Mr. Toke.

The second question was, How came it that Hornby--if he was indeed the
mysterious visitor--should have left this treasure-house intact? Many of
the pieces were quite portable, especially to a man with a car. And, as
Miller had pointed out, they could have been disposed of quite safely, so
long as they had not been missed. The first question could not be
discussed in Woodburn's presence, but the second I ventured to put to
Thorndyke.

"I think the explanation is fairly simple," he replied. "There appears to
have been here an accumulation of gold bullion. How much we cannot guess,
nor how it came to be accumulated. But here it was, and its presence was
probably known to, or suspected by, the murderer, though it may have been
discovered after the murder. My impression--though it is nothing more--is
that the murder was not committed ad hoc--as a means to the carrying
out of the robbery, but for some reason that is not known to us, and that
the gold robbery was, as it were, a by-product.

"Now, the existence of this gold bullion was, almost certainly, known to
no one but Mr. Toke. It follows that if the murderer could have simply
taken away the gold and then disappeared, he would have left no trace
whatever of his having ever been here. The corpse, you remember, is in a
coffin in the vault, to which the only access is by secret openings whose
existence was unknown to anybody but Mr. Toke. You see the masterly
simplicity of the plan. When Mr. Toke failed to return or give any sign
of being alive, and leave had been granted by the court to presume death,
these rooms would have been opened and everything found apparently
intact. There would have been nothing whatever to suggest any crime. It
might have been suspected that Mr. Toke had met with foul play. But not
here. The scene of his disappearance would have been placed in some
unknown locality abroad.

"But now suppose that this man, in addition to taking away the gold, had
rifled the collection. Then, as soon as the rooms were entered, it would
have been seen that there had been a robbery. But a robbery in
conjunction with a disappearance at once suggests a murder. There would
have been a search, with the possible, and even probable, discovery of
the body. Obviously, it was worth the murderer's while to abstain from
tampering with the collection."

The afternoon wore on and merged into evening. The daylight faded, and,
as the twilight deepened and the night closed in on the old house, we
felt that the time had come to set the watch. For this was a quiet
country neighbourhood where people went to rest early and measured time
by the sun rather than by the clock. Accordingly, we went forth in search
of the Superintendent and found him in the act of mustering his forces,
preparatory to placing them at their posts in the churchyard.

"It seems a bit early," said he. "But it won't do to be caught napping.
Our friends may turn up earlier than we expect. I'll just go out and see
my men posted, and then we will make our arrangements."

With this he departed and we proceeded with the preliminaries that
concerned us. First Woodburn instructed Mrs. Gibbins to have all lights
out at the usual time--which appeared to be ten o'clock--and advised
that the inmates should go to bed when they put out the lights (which I
suspected to be a counsel of perfection that was not likely to be
followed). Then we made out our programme for the night watch in the
gallery. Woodburn not only volunteered, but insisted on joining the
party; and Polton, when he was offered the use of a spare bedroom,
became, for the first time on record, positively mutinous, absolutely
refusing to be driven away from the scene of action. So he had to be put
on the roster of the "garrison," and proceeded with us to the gallery to
take up our final positions, where we were presently joined by the
Superintendent.

"Well," the latter remarked, surveying our party with a grin, "if there
is only one man, we ought to be able to manage him. Seven of us, all
told. Seems as if we weren't taking many risks. Of course, if there
should be more than one, we shan't be too many. And now we've got to
settle on our stations, because, when once we have taken them, we must
keep them. There must be no moving about. Now, we can't lock that door,
as there is no keyhole on the inside, so one or two of us had better take
post in the first room--the one that is next to the door. The question
is, which of us?"

"I think you had better take that post, Miller," said Thorndyke, "as that
is where he, or they, will probably have to be stopped. They will know
that the door is unlocked as soon as they discover that someone is in the
room, and, as the secret door will be blocked, they will naturally make a
burst for the main door."

"Yes," agreed Miller, "I think you are right, Doctor. Then I propose that
Mr. Woodburn and I take the end room, and the rest of you take post in
the workshop, where you will be close to the secret door."

These arrangements having been agreed to, Thorndyke made a final round to
make sure that nothing was visible that might create premature suspicion.
First, he inspected the secret door, and set the catch exactly as he had
found it, wiping away the last traces of the dusting powder by the light
of his lamp (for we had put on no lights in the gallery). Then he went to
the main door, and, taking the dangling remains of the seal, heated the
wax with a lighted match (which he carefully shrouded with his hand), and
stuck it in its original place so that, to a casual glance, it appeared
to be unbroken.

"Now, I think we are all ready," said he, "and it is about time that we
took our places."

The existing arrangements did not make for luxury, or even common
comfort. The Superintendent and Woodburn found in their room one chair,
and collected another from the adjoining room. But in the workshop there
was but one hideously incommodious stool, which we all rejected,
preferring to seat ourselves on the bench, when we had removed the flasks
and other obstructions. It was far from being a comfortable seat, and the
shelves behind it offered but an uneasy support to the back. However,
Thorndyke reminded us that many a journeyman tailor spent the greater
part of his life seated on just such a bench, and added with undoubted
truth that it had the virtue of offering a steady resistance to any
tendency to drowsiness.

I look back on that long vigil as one of the strangest experiences of my
life. It was like that of a big-game hunter, offering a curious
combination of tedium and excitement, of wearisome monotony with the need
for incessant alertness and the uncertainty as to what the next moment
might bring forth, or whether it might bring forth anything. We took our
places, very prematurely, at half-past nine; and thereafter we sat in the
dark, conversing little, and then in the softest of whispers, and hardly
daring to change our positions. It would have been a relief to smoke, but
this was, of course, forbidden, though at intervals, a faint sniff,
accompanied by the suspicion of a distinctive scent, informed me that
Polton was indulging in the mild dissipation of a pinch of snuff. Once,
indeed, the cold touch of a metal snuff-box on my hand was accompanied by
a whispered invitation to test the virtues of Brown Rappee; an invitation
which I half-reluctantly declined.

The tardy minutes crawled on with incredible slowness. Sitting there in
the darkness, encompassed, as it seemed, by the silence of the tomb, I
was able to mark their passage by the chimes of a clock, somewhere in the
village, which were borne faintly to my ear across the quiet countryside.
The clock struck the quarters; but each quarter seemed to have the
duration of an hour. I fingered the automatic pistol in my pocket and
wondered what degree of urgency would induce me to use it. Like
Thorndyke, I had a profound dislike of firearms; and none of our party
had seemed to show much enthusiasm when he handed them out. Miller had
the typical police officer's contempt for a mere assassin's weapon, and
had offered his to Polton. But Polton assured him that he had never fired
a pistol in his life and should probably hit the wrong man; upon which
Miller hastily took it back.

The distant clock had struck half-past ten when the dreariness of our
vigil was to some extent mitigated by the appearance of the moon. It
first came into view through the curtained window of the gallery which
was just visible through the half-open door of the workshop, as a
misshapen, coppery disc (for it was a few days past the full), just
peeping above the window-sill. Then, by slow degrees, it crept up higher
and higher; and, as its dull copper brightened into a warm, ruddy glow
and then to a clear, cold, silvery sheen, the shape of the lofty window
became traced on the floor in an elongated, luminous patch, on which the
pattern of the lace curtains stood out clearly in forms of delicate
shadow.

That shape of patterned moonlight came as a welcome distraction which
helped to fill the long intervals between the chimes of the distant
clock. Like some solitary prisoner in his cell, I followed its infinitely
slow progress across the floor, idly calculating the time that it would
take to reach the foot of the pilaster in which was the secret door. At
present, the pilaster was enveloped in dense, black shadow, and a wide
space of floor separated it from the patch of moonlight. I tried to think
of that space in terms of angular distance and time, but failed to reach
any intelligible result. Then I fell to thinking about the man for whom
we were waiting. Was he now on the road, drawing gradually nearer to his
doom--or, perchance, ours? If so, how far away was he now? Was he
travelling alone or had he companions with whom we should have to reckon?
Or was he, even now, comfortably tucked up in bed in some far-away
hiding-place with no intention of sallying forth this night? Or was he
lurking in the village, fully warned by the sight of us to keep out of
the way? To leave us to our profitless vigil until the coming of daylight
should send us away, drowsy and defeated?

The silence of the old house was like the silence of some cavern in the
heart of a mountain. Save for the infrequent chime of the far-away clock,
there was not a sound. Not a window rattled--for it was a still night--not
a joist creaked, no mouse "shrieked in the wainscot" or scuttled
through its burrow. None of the ordinary night sounds of an old house
were audible. It was as still as the inside of a pyramid.

A few minutes had passed since the hardly audible chime of the distant
clock had told out the half-hour after eleven when that deathly silence
was, for the first time, disturbed by a sound that seemed to come from
within the house. And, even then, it was so faint and indefinite that I
doubted whether I had, in fact, heard anything. I listened intently.
Then, after the lapse of nearly a minute, it was repeated. It conveyed
nothing to me. It was just a sound--infinitely faint and remote, and so
devoid of any recognizable character that I was still doubtful. But at
this moment Thorndyke silently slid off the bench and was followed--less
silently--by Polton. I, too, slipped my legs over the edge and, as I
stood upright beside Thorndyke, I asked in a whisper:

"Did you think you heard anything?"

"Yes," he replied. "It was the slab turning on its pivot. Listen!"

I strained my ears, but for a few moments I could hear no further sound.
Then I became aware of a faint but distinctly audible murmur or rustle as
if a number of separate sounds were being confused by echoes. Suddenly it
became much more distinct and changed in character; for now I could
clearly distinguish footsteps--soft, stealthy footsteps, mingled with
their reverberations, but unmistakable.

Nearer and nearer they came, still secret and stealthy, but now
recognizable as the tread of feet on the long stairway. Once, the feet
slipped or stumbled, and the sound of some hard object striking the
steps, followed by a muttered curse, told me that the man was nearer than
I had thought. Suddenly on the side of the pilaster, there appeared a
bright thread--the light of a lamp from the stairway shining through the
crack of the secret door.

With a throbbing heart I watched that thread of light, drawn on the black
shadow of the pilaster, as it waxed in brightness from moment to moment.
At last plain sounds from within the woodwork told us that our visitor
had come. There was a soft scraping like the sound of a groping hand; two
successive creaks followed by a sharp click. Then the secret door swung
open, and a man stepped out into the room.

At first, he was no more than a dim, dark shape, as he stood in the
shadow; but when he moved, I could see that he was hatless, and that he
carried a good-sized hand-bag in one hand and in the other what looked
like a large electric lamp, the light of which was switched off. From the
door he went across to the table and laid his bag on it. Then he walked
softly up the room until he came to the door, where he switched on his
lamp and threw its light on the seals. Apparently their appearance
satisfied him, for he turned away after a brief glance; but then, as if
by an after-thought, he turned back and threw the light on again.
Evidently he had detected something amiss, for, after a few moments'
inspection, he mounted the steps to examine the seals more closely. As be
did so, Thorndyke glided like a shadow from the workshop door to the
pilaster, where he halted just in front of the secret opening. Almost at
the same moment looking out from the workshop, I saw another shadow glide
out of the door of the farther room without a sound and slip round behind
the stranger as he ascended the steps.

At this point, I crept silently out into the gallery, for the reflection
from the moonlit floor enabled me to recognize this second shadow as the
Superintendent, and I knew that the critical moment had come. It had
seemed to me that Miller had moved quite noiselessly, but apparently I
was wrong; for, at the very moment when his arm stretched out to seize
his prey, the stranger turned sharply, and, as the light of his lamp fell
on the Superintendent, he uttered a sort of snarl, struck out viciously,
and wrenched himself away, springing from the steps and racing down the
room, closely pursued by Miller and Woodburn.

As to what followed my recollections are somewhat confused. It all
happened so quickly and the light was so imperfect that nothing but a
general impression remains. I saw the fugitive adroitly catch up a chair
and whirl it back at his pursuers, with the result that Miller staggered
heavily sideways, and Woodburn, whose legs it struck, fell sprawling on
the floor. The next moment, as the man swerved to pass the workshop door,
the light of his lamp fell on Thorndyke. I think that in that instant he
must have recognized him, for he uttered a savage cry, checked for a
moment, and then threw out his arm. Instantly I realized, though I could
not see it, that the hand of that extended arm held a pistol, and I
started forward. But at that instant something hurtled past me and struck
the stranger in the face with such force that he staggered backward. The
report of the pistol rang out sharply, and the missile, whatever it was,
clattered heavily on the floor.

It had been a near thing; and, indeed it was not yet over, though Miller
had now rushed forward and grasped the pistol arm while I sprang at the
other. But our prisoner fought and struggled like a maniac, yet with a
settled purpose, for the flash and report of the pistol were repeated
again and again, not at random, but always when the weapon could be
brought to bear in Thorndyke's direction. Now, however, my colleague,
having closed and fastened the secret door, came forward to take a hand
with the light of his lamp turned full on the struggling, swaying group,
which had now been joined by Woodburn.

Suddenly I heard Thorndyke call out sharply:

"Keep out of the way, Polton!" At the same moment I caught sight of our
artificer, skirmishing round at Miller's side, with his eyes riveted on
the pistol. Almost as Thorndyke spoke, a pair of large crucible-tongs
came into view, reaching out towards the hand which held the weapon.
There was a quick but unhurried movement, and the tongs took firm hold of
the pistol by its flat stock. Then the long handles were quietly raised
and twisted the weapon irresistibly out of the prisoner's grasp.

The removal of the pistol brought the struggle virtually to an end. I
did, indeed, feel the hand which I controlled thrusting towards the
waist-belt. But I had already detected the presence there of a
sheath-knife of formidable size, and I easily circumvented the movement.
And, when Thorndyke seized both the prisoner's wrists and held them
together, Miller was able to snap on the handcuffs. Even then, our
prisoner continued to struggle violently; and it was not until Thorndyke
had encircled his legs and pinioned his arms with a couple of document
straps (which he had, apparently, put in his pocket for that purpose)
that his resistance ceased. Then we sat him in a chair, and, while we
recovered our breath, considered the next move.

"I think," said Miller, "I will just run across to the churchyard and
relieve my men. They may be able to produce some sort of transport. If
not, I shall have to borrow Mr. Woodburn's car. I leave the prisoner in
your custody, Doctor."

As soon as he had gone, Woodburn proceeded to light the two hanging lamps
which swung by long chains from beams in the gallery ceiling--for there
was neither gas nor electric light in the house--when we were able to
survey one another and examine our prisoner. Woodburn was the only one of
us who had suffered visibly from the encounter, having an undeniable
black eye. But the prisoner was a sorry spectacle, and, villain as he
was, I could not but feel some twinges of compunction as I looked at him.
His face was badly bruised and bleeding; at which I was not surprised,
when I picked up the missile that had struck him and recognized it as
Polton's "case-opener." But what most contributed to his forlorn and
wretched aspect was his bald head, from which the wig had been dislodged
during the fray. It was not a common, natural, and decent bald head,
which would have been normal enough, but the baldness was in large
patches with separating areas of stubble; the condition, in fact, known
to our profession as Alopecia areata.

I picked up the wig and carefully replaced it on his head, disregarding
his profane and furious protests. Then I went with Thorndyke to the
workshop, where the research case had been deposited, to fetch the little
first-aid case that was part of its permanent equipment, and, as I was
thus engaged, Thorndyke proceeded to moralize.

"That Alopecia is interesting," he remarked. "I mean, as an illustration
of the incalculability of human affairs. If he had not been compelled to
wear a wig, he would probably never have thought of personating Dobey.
Probably, too, he would not have murdered Badger--at any rate not in
that way; and he might not have murdered Toke. Evidently, the course of
his criminal career has been largely influenced by his Alopecia. He had
to wear a wig, but he could wear any kind of wig that he pleased and
change it at any time for any other kind that circumstances seemed to
require."

"Yes," I agreed; "a disguise which has to be habitually worn naturally
suggests additions and variations."

I took the little emergency case and a basin of water, and we went back
to the prisoner. As I was mixing some lotion while Thorndyke prepared a
dressing, the patient watched him with a glare of the most concentrated
malice.

"Don't you touch me, you devil!" he exclaimed, huskily, "or I'll bite
you. I ought to have settled with you years ago."

In different circumstances it might have been permissible to remind him
that he had made three pretty determined attempts. Nevertheless, as a
matter of policy, he was certainly right. But for Thorndyke, he would
have been, at this moment, at large and unsuspected.

I had hardly finished attending to his damaged face when Miller returned.

"We shall be able to manage quite well," he announced. "My men discovered
a car in that lane--heard it arrive, in fact. So I shan't want Mr.
Woodburn's. We can take him to London in his own car."

Here the two officers entered, and, advancing up the gallery, took a long
and curious look at the prisoner. Then Miller proceeded to make the
formal charge.

"I arrest you, Walter Hornby, for the murder of Mr. Didbury Toke; and I
caution you that anything you say will be taken down in writing and may
be used against you--"

"Oh, go to blazes!" interrupted Hornby. "Do you think I am a cackling old
woman? I am not going to say anything."

Nevertheless, in spite of his bravado, I had the impression that the
nature of the charge came as an appalling shock. I think he had expected
to be charged only with breaking and entering, for after this outburst he
settled down into sullen silence and submitted passively to being carried
away by the two officers. Only once, as he was borne out, he turned his
head to bestow on Thorndyke a look of the most concentrated malignancy.

When the grim procession, accompanied by the Superintendent, had passed
out and the footsteps had died away, Thorndyke turned to his faithful
henchman and laid his hand on his shoulder.

"It was fortunate for me, Polton," said he, "that you would not go to
bed. But for that remarkable shot of yours, I think Hornby would have
settled his account with me, after all."

Polton crinkled apologetically and gave a little embarrassed cough as he
replied:

"Yes, sir, I thought I might be useful. You see, sir, when I was younger,
I used to take a good deal of practice at the coco-nuts on Hampstead
Heath. I got to be quite a dab at 'em; and the Aunt Sallies, too."

At this moment, the gallery door opened, and Mrs. Gibbins entered
spectrally, bearing a lighted candle in a bedroom candlestick.

"I've come to tell you, sir," she said, addressing Woodburn, "that I have
laid supper in the dining-room. Mr. Miller is coming back to join you
when he has seen the other officers off in the car."

It was an undeniably welcome announcement; and, when Woodburn had
extinguished the lamps, we switched on our electric lanterns and followed
the housekeeper along the winding corridor.

Chapter XVIII Postscript

WITH the arrest of Walter Hornby, this history--which is that of an
investigation--naturally comes to an end. In the course of the events
that followed, nothing transpired that could be regarded as a new
discovery. Certain details were filled in, and certain conclusions which
had been arrived at by inference were confirmed by actual demonstration.
Thus, at the inquest, it was proved that Mr. Toke had died from a deep
knife wound, and the evidence left no doubt that it had been inflicted,
as Thorndyke had suggested, just as he was in the act of emerging from
the tomb. The wound corresponded exactly with the knife which was on
Hornby's person when he was arrested. And, though that knife had been
carefully washed, when Polton, under Thorndyke's supervision, unriveted
and removed the wooden handle, considerable traces of blood were
discovered; sufficient, in fact, to admit of a biochemical test which
showed it to be human blood.

At the trial, there was practically no defence, nor was there any appeal
from the conviction and sentence. The prisoner was indicted for the
murder of Mr. Toke, the other crime being held back for a further
indictment in the unlikely event of an acquittal. But of an acquittal
there was never the remotest chance. For, in addition to the profoundly
incriminating fact that Hornby had been captured in actual occupation of
the murdered man's premises and in command of the secret passages in
which the body was concealed, there was the utterly damning fact that Mr.
Toke's signet ring was found in his pocket when he was searched after his
arrest.

It was unavoidable that the trial and its dreadful sequel should
be a cause of pain to many estimable people, including his cousin
Reuben--against whom he had hatched such a dastardly plot in the
years gone by. To my wife, who had been almost in the position of a
relative, the whole sordidly tragic affair was so harrowing that we
tacitly agreed not to speak of it. Even I, who had known the man in the
days of his prosperity and respectability, could hardly bring myself
to contemplate his present terrible plight; and I was almost disposed
to resent Thorndyke's calm, impersonal interest in the trial and his
satisfaction at the conviction and the sentence. For a man so kindly
by nature, this callousness--as it appeared to me--seemed surprising
and hardly natural. I think I must have given expression to some such
sentiments on the day, I remember, when the execution had just taken
place, and he was calmly collecting the notes and memoranda of the case
to put away in the files where the records were kept. His reply was
characteristic and, looking back, I am not much disposed to cavil at it.

"I understand, Jervis," said he, "your personal discomfort in
contemplating this tragedy; the shipwreck of a life that started with so
much promise and had such potentialities of usefulness and success. But
it is a mistake to grow sentimental over the Nemesis that awaits the
criminal. The most far-reaching mercy that can be exercised in social
life is to safeguard the liberties of those who respect the liberties of
others. Believe me, Jervis, the great purveyor of human happiness is not
philanthropy, which seeks to soften the lot of the unworthy, but justice,
which secures to the worthy the power to achieve their own happiness, by
protecting them from the wrong-doer and the social parasite."
