PART I

THE CHANGED IMMUTABLE

Among the minor and purely physical pleasures of life, I am disposed

to rank very highly that feeling of bodily comfort that one

experiences on passing from the outer darkness of a wet winter’s

night to a cheerful interior made glad by mellow lamplight and

blazing hearth. And so I thought when, on a dreary November night, I

let myself into our chambers in the Temple and found my friend

smoking his pipe in slippered ease, by a roaring fire, and facing an

empty armchair evidently placed in readiness for me.

As I shed my damp overcoat, I glanced inquisitively at my colleague,

for he held in his hand an open letter, and I seemed to perceive in

his aspect something meditative and self-communing--something, in

short, suggestive of a new case.

“I was just considering,” he said, in answer to my inquiring look,

“whether I am about to become an accessory after the fact. Read that

and give me your opinion.”

He handed me the letter, which I read aloud.

“DEAR SIR,--I am in great danger and distress. A warrant has been

issued for my arrest on a charge of which I am entirely innocent. Can

I come and see you, and will you let me leave in safety? The bearer

will wait for a reply.”

“I said ‘Yes,’ of course; there was nothing else to do,” said

Thorndyke. “But if I let him go, as I have promised to do, I shall be

virtually conniving at his escape.”

“Yes, you are taking a risk,” I answered. “When is he coming?”

“He was due five minutes ago--and I rather think--yes, here he is.”

A stealthy tread on the landing was followed by a soft tapping on the

outer door.

Thorndyke rose and, flinging open the inner door, unfastened the

massive “oak.”

“Dr. Thorndyke?” inquired a breathless, quavering voice.

“Yes, come in. You sent me a letter by hand?”

“I did, sir,” was the reply; and the speaker entered, but at the

sight of me he stopped short.

“This is my colleague, Dr. Jervis,” Thorndyke explained. “You need

have no----”

“Oh, I remember him,” our visitor interrupted in a tone of relief. “I

have seen you both before, you know, and you have seen me too--though

I don’t suppose you recognize me,” he added, with a sickly smile.

“Frank Belfield?” asked Thorndyke, smiling also.

Our visitor’s jaw fell and he gazed at my colleague in sudden dismay.

“And I may remark,” pursued Thorndyke, “that for a man in your

perilous position, you are running most unnecessary risks. That wig,

that false beard and those spectacles--through which you obviously

cannot see--are enough to bring the entire police force at your

heels. It is not wise for a man who is wanted by the police to make

up as though he had just escaped from a comic opera.”

Mr. Belfield seated himself with a groan, and, taking off his

spectacles, stared stupidly from one of us to the other.

“And now tell us about your little affair,” said Thorndyke. “You say

that you are innocent?”

“I swear it, doctor,” replied Belfield; adding, with great

earnestness, “And you may take it from me, sir, that if I was not, I

shouldn’t be here. It was you that convicted me last time, when I

thought myself quite safe, so I know your ways too well to try to

gammon you.”

“If you are innocent,” rejoined Thorndyke, “I will do what I can for

you; and if you are not--well, you would have been wiser to stay

away.”

“I know that well enough,” said Belfield, “and I am only afraid that

you won’t believe what I am going to tell you.”

“I shall keep an open mind, at any rate,” replied Thorndyke.

“If you only will,” groaned Belfield, “I shall have a look in, in

spite of them all. You know, sir, that I have been on the crook, but

I have paid in full. That job when you tripped me up was the last of

it--it was, sir, so help me. It was a woman that changed me--the best

and truest woman on God’s earth. She said she would marry me when I

came out if I promised her to go straight and live an honest life.

And she kept her promise--and I have kept mine. She found me work as

clerk in a warehouse and I have stuck to it ever since, earning fair

wages and building up a good character as an honest, industrious man.

I thought all was going well and that I was settled for life, when

only this very morning the whole thing comes tumbling about my ears

like a house of cards.”

“What happened this morning, then?” asked Thorndyke.

“Why, I was on my way to work when, as I passed the police station, I

noticed a bill with the heading ‘Wanted’ and a photograph. I stopped

for a moment to look at it, and you may imagine my feelings when I

recognized my own portrait--taken at Holloway--and read my own name

and description. I did not stop to read the bill through, but ran

back home and told my wife, and she ran down to the station and read

the bill carefully. Good God, sir! What do you think I am wanted

for?” He paused for a moment, and then re plied in breathless tones

to his own question: “The Camberwell murder!”

Thorndyke gave a low whistle.

“My wife knows I didn’t do it,” continued Belfield, “because I was at

home all the evening and night; but what use is a man’s wife to prove

an alibi?”

“Not much, I fear,” Thorndyke admitted; “and you have no other

witness?”

“Not a soul. We were alone all the evening.”

“However,” said Thorndyke, “if you are innocent--as I am

assuming--the evidence against you must be entirely circumstantial

and your alibi may be quite sufficient. Have you any idea of the

grounds of suspicion against you?”

“Not the faintest. The papers said that the police had an excellent

clue, but they did not say what it was. Probably some one has given

false information for the----”

A sharp rapping at the outer door cut short the explanation, and our

visitor rose, trembling and aghast, with beads of sweat standing upon

his livid face.

“You had better go into the office, Belfield, while we see who it

is,” said Thorndyke. “The key is on the inside.”

The fugitive wanted no second bidding, but hurried into the empty

apartment, and, as the door closed, we heard the key turn in the lock.

As Thorndyke threw open the outer door, he cast a meaning glance at

me over his shoulder which I understood when the newcomer entered the

room; for it was none other than Superintendent Miller of Scotland

Yard.

“I have just dropped in,” said the superintendent, in his brisk,

cheerful way, “to ask you to do me a favour. Good evening, Dr.

Jervis. I hear you are reading for the bar; learned counsel soon,

sir, hey? Medico-legal expert. Dr. Thorndyke’s mantle going to fall

on you, sir?”

“I hope Dr. Thorndyke’s mantle will continue to drape his own

majestic form for many a long year yet,” I answered; “though he is

good enough to spare me a corner--but what on earth have you got

there?” For during this dialogue the Superintendent had been deftly

unfastening a brown-paper parcel, from which he now drew a linen

shirt, once white, but now of an unsavoury grey.

“I want to know what this is,” said Miller, exhibiting a brownish-red

stain on one sleeve. “Just look at that, sir, and tell me if it is

blood, and, if so, is it human blood?”

“Really, Miller,” said Thorndyke, with a smile, “you flatter me; but

I am not like the wise woman of Bagdad who could tell you how many

stairs the patient had tumbled down by merely looking at his tongue.

I must examine this very thoroughly. When do you want to know?”

“I should like to know to-night,” replied the detective.

“Can I cut a piece out to put under the microscope?”

“I would rather you did not,” was the reply.

“Very well; you shall have the information in about an hour.”

“It’s very good of you, doctor,” said the detective; and he was

taking up his hat preparatory to departing, when Thorndyke said

suddenly----

“By the way, there is a little matter that I was going to speak to

you about. It refers to this Camberwell murder case. I understand you

have a clue to the identity of the murderer?”

“Clue!” exclaimed the superintendent contemptuously. “We have spotted

our man all right, if we could only lay hands on him; but he has

given us the slip for the moment.”

“Who is the man?” asked Thorndyke.

The detective looked doubtfully at Thorndyke for some seconds and

then said, with evident reluctance: “I suppose there is no harm in

telling you--especially as you probably know already”--this with a

sly grin; “it’s an old crook named Belfield.”

“And what is the evidence against him?”

Again the superintendent looked doubtful and again relented.

“Why, the case is as clear as--as cold Scotch,” he said (here

Thorndyke in illustration of this figure of speech produced a

decanter, a syphon and a tumbler, which he pushed towards the

officer). “You see, sir, the silly fool went and stuck his sweaty

hand on the window; and there we found the marks--four fingers and a

thumb, as beautiful prints as you could wish to see. Of course we cut

out the piece of glass and took it up to the Finger-print Department;

they turned up their files and out came Mr. Belfield’s record, with

his finger-prints and photograph all complete.”

“And the finger-prints on the window-pane were identical with those

on the prison form?”

“Identical.”

“H’m!” Thorndyke reflected for a while, and the superintendent

watched him foxily over the edge of his tumbler.

“I guess you are retained to defend Belfield,” the latter observed

presently.

“To look into the case generally,” replied Thorndyke.

“And I expect you know where the beggar is hiding,” continued the

detective.

“Belfield’s address has not yet been communicated to me,” said

Thorndyke. “I am merely to investigate the case--and there is no

reason, Miller, why you and I should be at cross purposes. We are

both working at the case; you want to get a conviction and you want

to convict the right man.”

“That’s so--and Belfield’s the right man--but what do you want of us,

doctor?”

“I should like to see the piece of glass with the finger-prints on

it, and the prison form, and take a photograph of each. And I should

like to examine the room in which the murder took place--you have it

locked up, I suppose?”

“Yes, we have the keys. Well, it’s all rather irregular, letting you

see the things. Still, you’ve always played the game fairly with us,

so we might stretch a point. Yes, I will. I’ll come back in an hour

for your report and bring the glass and the form. I can’t let them go

out of my custody, you know. I’ll be off now--no, thank you, not

another drop.”

The superintendent caught up his hat and strode away, the

personification of mental alertness and bodily vigour.

No sooner had the door closed behind him than Thorndyke’s stolid calm

changed instantaneously into feverish energy. Darting to the electric

bell that rang into the laboratories above, he pressed the button

while he gave me my directions.

“Have a look at that bloodstain, Jervis, while I am finishing with

Belfield. Don’t wet it; scrape it into a drop of warm normal saline

solution.”

I hastened to reach down the microscope and set out on the table the

necessary apparatus and reagents, and, as I was thus occupied, a

latch-key turned in the outer door and our invaluable helpmate,

Polton, entered the room in his habitual silent, unobtrusive fashion.

“Let me have the finger-print apparatus, please, Polton,” said

Thorndyke; “and have the copying camera ready by nine o’clock. I am

expecting Mr. Miller with some documents.”

As his laboratory assistant departed, Thorndyke rapped at the office

door.

“It’s all clear, Belfield,” he called; “you can come out.”

The key turned and the prisoner emerged, looking ludicrously

woebegone in his ridiculous wig and beard.

“I am going to take your finger-prints, to compare with some that the

police found on the window.”

“Finger-prints!” exclaimed Belfield, in a tone of dismay. “They don’t

say they’re my finger-prints, do they, sir?”

“They do indeed,” replied Thorndyke, eyeing the man narrowly. “They

have compared them with those taken when you were at Holloway, and

they say that they are identical.”

“Good God!” murmured Belfield, collapsing into a chair, faint and

trembling. “They must have made some awful mistake. But are mistakes

possible with finger-prints?”

“Now look here, Belfield,” said Thorndyke. “Were you in that house

that night, or were you not? It is of no use for you to tell me any

lies.”

“I was not there, sir; I swear to God I was not.”

“Then they cannot be your finger-prints, that is obvious.” Here he

stepped to the door to intercept Polton, from whom he received a

substantial box, which he brought in and placed on the table.

“Tell me all you know about this case,” he continued, as he set out

the contents of the box on the table.

“I know nothing about it whatever,” replied Belfield; “nothing, at

least, except----”

“Except what?” demanded Thorndyke, looking up sharply as he squeezed

a drop from a tube of finger-print ink onto a smooth copper plate.

“Except that the murdered man, Caldwell, was a retired fence.”

“A fence, was he?” said Thorndyke in a tone of interest.

“Yes; and I suspect he was a ‘nark’ too. He knew more than was

wholesome for a good many.”

“Did he know anything about you?”

“Yes; but nothing that the police don’t know.”

With a small roller Thorndyke spread the ink upon the plate into a

thin film. Then he laid on the edge of the table a smooth white card

and, taking Belfield’s right hand, pressed the forefinger firmly but

quickly, first on the inked plate and then on the card, leaving on

the latter a clear print of the finger-tip. This process he repeated

with the other fingers and thumb, and then took several additional

prints of each.

“That was a nasty injury to your forefinger, Belfield,” said

Thorndyke, holding the finger to the light and examining the tip

carefully. “How did you do it?”

“Stuck a tin-opener into it--a dirty one, too. It was bad for weeks;

in fact, Dr. Sampson thought at one time that he would have to

amputate the finger.”

“How long ago was that?”

“Oh, nearly a year ago, sir.”

Thorndyke wrote the date of the injury by the side of the

finger-print and then, having rolled up the inking plate afresh, laid

on the table several larger cards.

“I am now going to take the prints of the four fingers and the thumb

all at once,” he said.

“They only took the four fingers at once at the prison,” said

Belfield. “They took the thumb separately.”

“I know,” replied Thorndyke; “but I am going to take the impression

just as it would appear on the window glass.”

He took several impressions thus, and then, having looked at his

watch, he began to repack the apparatus in its box. While doing this,

he glanced, from time to time, in meditative fashion, at the

suspected man who sat, the living picture of misery and terror,

wiping the greasy ink from his trembling fingers with his

handkerchief.

“Belfield,” he said at length, “you have sworn to me that you are an

innocent man and are trying to live an honest life. I believe you;

but in a few minutes I shall know for certain.”

“Thank God for that, sir,” exclaimed Belfield, brightening up

wonderfully.

“And now,” said Thorndyke, “you had better go back into the office,

for I am expecting Superintendent Miller, and he may be here at any

moment.”

Belfield hastily slunk back into the office, locking the door after

him, and Thorndyke, having returned the box to the laboratory and

deposited the cards bearing the finger-prints in a drawer, came round

to inspect my work. I had managed to detach a tiny fragment of dried

clot from the bloodstained garment, and this, in a drop of normal

saline solution, I now had under the microscope.

“What do you make out, Jervis?” my colleague asked.

“Oval corpuscles with distinct nuclei,” I answered.

“Ah,” said Thorndyke, “that will be good hearing for some poor devil.

Have you measured them?”

“Yes. Long diameter 1/2100 of an inch; short diameter about 1/3400.”

Thorndyke reached down an indexed note-book from a shelf of reference

volumes and consulted a table of histological measurements.

“That would seem to be the blood of a pheasant, then, or it might,

more probably, be that of a common fowl.” He applied his eye to the

microscope and, fitting in the eye-piece micrometer, verified my

measurements. He was thus employed when a sharp tap was heard on the

outer door, and rising to open it he admitted the superintendent.

“I see you are at work on my little problem, doctor,” said the

latter, glancing at the microscope. “What do you make of that stain?”

“It is the blood of a bird--probably a pheasant, or perhaps a common

fowl.”

The superintendent slapped his thigh. “Well, I’m hanged!” he

exclaimed. “You’re a regular wizard, doctor, that’s what you are. The

fellow said he got that stain through handling a wounded pheasant and

here are you able to tell us yes or no without a hint from us to help

you. Well, you’ve done my little job for me, sir, and I’m much

obliged to you; now I’ll carry out my part of the bargain.” He opened

a handbag and drew forth a wooden frame and a blue foolscap envelope

and laid them with extreme care on the table.

“There you are, sir,” said he, pointing to the frame; “you will find

Mr. Belfield’s trademark very neatly executed, and in the envelope is

the finger-print sheet for comparison.”

Thorndyke took up the frame and examined it. It enclosed two sheets

of glass, one being the portion of the window-pane and the other a

cover-glass to protect the finger prints. Laying a sheet of white

paper on the table, where the light was strongest, Thorndyke held the

frame over it and gazed at the glass in silence, but with that faint

lighting up of his impassive face which I knew so well and which

meant so much to me. I walked round, and looking over his shoulder

saw upon the glass the beautifully distinct imprints of four fingers

and a thumb--the finger-tips, in fact, of an open hand.

After regarding the frame attentively for some time, Thorndyke

produced from his pocket a little wash-leather bag, from which he

extracted a powerful doublet lens, and with the aid of this he again

explored the finger-prints, dwelling especially upon the print of the

forefinger.

“I don’t think you will find much amiss with those finger-prints,

doctor,” said the superintendent, “they are as clear as if he made

them on purpose.”

“They are indeed,” replied Thorndyke, with an inscrutable smile,

“exactly as if he had made them on purpose. And how beautifully clean

the glass is--as if he had polished it before making the impression.”

The superintendent glanced at Thorndyke with quick suspicion; but the

smile had faded and given place to a wooden immobility from which

nothing could be gleaned.

When he had examined the glass exhaustively, Thorndyke drew the

finger-print form from its envelope and scanned it quickly, glancing

repeatedly from the paper to the glass and from the glass to the

paper. At length he laid them both on the table, and turning to the

detective looked him steadily in the face.

“I think, Miller,” said he, “that I can give you a hint.”

“Indeed, sir? And what might that be?”

“It is this: you are after the wrong man.”

The Superintendent snorted--not a loud snort, for that would have

been rude, and no officer could be more polite than Superintendent

Miller. But it conveyed a protest which he speedily followed up in

words.

“You don’t mean to say that the prints on that glass are not the

finger-prints of Frank Belfield?”

“I say that those prints were not made by Frank Belfield,” Thorndyke

replied firmly.

“Do you admit, sir, that the finger-prints on the official form were

made by him?”

“I have no doubt that they were.”

“Well, sir, Mr. Singleton, of the Finger-print Department, has

compared the prints on the glass with those on the form and he says

they are identical; and I have examined them and I say they are

identical.”

“Exactly,” said Thorndyke; “and I have examined them and I say they

are identical--and that therefore those on the glass cannot have been

made by Belfield.”

The Superintendent Snorted again--somewhat louder this time--and

gazed at Thorndyke with wrinkled brows.

“You are not pulling my leg, I suppose, sir?” he asked, a little

sourly.

“I should as soon think of tickling a porcupine,” Thorndyke answered,

with a suave smile.

“Well,” rejoined the bewildered detective, “if I didn’t know you,

sir, I should say you were talking confounded nonsense. Perhaps you

wouldn’t mind explaining what you mean.”

“Supposing,” said Thorndyke, “I make it clear to you that those

prints on the window-pane were not made by Belfield. Would you still

execute the warrant?”

“What do _you_ think?” exclaimed Miller. “Do you suppose we should go

into court to have you come and knock the bottom out of our case,

like you did in that Hornby affair--by the way, that was a

finger-print case too, now I come to think of it,” and the

superintendent suddenly became thoughtful.

“You have often complained,” pursued Thorndyke, “that I have withheld

information from you and sprung unexpected evidence on you at the

trial. Now I am going to take you into my confidence, and when I have

proved to you that this clue of yours is a false one, I shall expect

you to let this poor devil Belfield go his way in peace.”

The superintendent grunted--a form of utterance that committed him to

nothing.

“These prints,” continued Thorndyke, taking up the frame once more,

“present several features of interest, one of which, at least, ought

not to have escaped you and Mr. Singleton, as it seems to have done.

Just look at that thumb.”

The superintendent did so, and then pored over the official paper.

“Well,” he said, “I don’t see anything the matter with it. It’s

exactly like the print on the paper.”

“Of course it is,” rejoined Thorndyke, “and that is just the point.

It ought not to be. The print of the thumb on the paper was taken

separately from the fingers. And why? Because it was impossible to

take it at the same time. The thumb is in a different plane from the

fingers; when the hand is laid flat on any surface--as this

window-pane, for instance--the palmar surfaces of the fingers touch

it, whereas it is the _side_ of the thumb which comes in contact and

not the palmar surface. But in this”--he tapped the framed glass with

his finger--“the prints show the palmar surfaces of all the five

digits in contact at once, which is an impossibility. Just try to put

your own thumb in that position and you will see that it is so.”

The detective spread out his hand on the table and immediately

perceived the truth of my colleague’s statement.

“And what does that prove?” he asked.

“It proves that the thumb-print on the window-pane was not made at

the same time as the finger-prints--that it was added separately; and

that fact seems to prove that the prints were not made accidentally,

but--as you ingeniously suggested just now--were put there for a

purpose.”

“I don’t quite see the drift of all this,” said the superintendent,

rubbing the back of his head perplexedly; “and you said a while back

that the prints on the glass can’t be Belfield’s because they are

identical with the prints on the form. Now that seems to me sheer

nonsense, if you will excuse my saying so.”

“And yet,” replied Thorndyke, “it is the actual fact. Listen: these

prints”--here he took up the official sheet--“were taken at Holloway

six years ago. These”--pointing to the framed glass--“were made

within the present week. The one is, as regards the ridge-pattern, a

perfect duplicate of the other. Is that not so?”

“That is so, doctor,” agreed the superintendent.

“Very well. Now suppose I were to tell you that within the last

twelve months something had happened to Belfield that made an

appreciable change in the ridge-pattern on one of his fingers?”

“But is such a thing possible?”

“It is not only possible but it has happened. I will show you.”

He brought forth from the drawer the cards on which Belfield had made

his finger-prints, and laid them before the detective.

“Observe the prints of the forefinger,” he said, indicating them;

“there are a dozen, in all, and you will notice in each a white line

crossing the ridges and dividing them. That line is caused by a scar,

which has destroyed a portion of the ridges, and is now an integral

part of Belfield’s finger-print. And since no such blank line is to

be seen in this print on the glass--in which the ridges appear

perfect, as they were before the injury--it follows that that print

could not have been made by Belfield’s finger.”

“There is no doubt about the injury, I suppose?”

“None whatever. There is the scar to prove it, and I can produce the

surgeon who attended Belfield at the time.”

The officer rubbed his head harder than before, and regarded

Thorndyke with puckered brows.

“This is a teaser,” he growled, “it is indeed. What you say, sir,

seems perfectly sound, and yet--there are those finger-prints on the

window-glass. Now you can’t get finger prints without fingers, can

you?”

“Undoubtedly you can,” said Thorndyke.

“I should want to see that done before I could believe even you,

sir,” said Miller.

“You shall see it done now,” was the calm rejoinder. “You have

evidently forgotten the Hornby case--the case of the Red Thumb-mark,

as the newspapers called it.”

“I only heard part of it,” replied Miller, “and I didn’t really

follow the evidence in that.”

“Well, I will show you a relic of that case,” said Thorndyke. He

unlocked a cabinet and took from one of the shelves a small box

labelled “Hornby,” which, being opened, was seen to contain a folded

paper, a little red-covered oblong book and what looked like a large

boxwood pawn.

“This little book,” Thorndyke continued, “is a ‘thumbograph’--a sort

of finger-print album--I dare say you know the kind of thing.”

The superintendent nodded contemptuously at the little volume.

“Now while Dr. Jervis is finding us the print we want, I will run up

to the laboratory for an inked slab.”

He handed me the little book and, as he left the room, I began to

turn over the leaves--not without emotion, for it was this very

“thumbograph” that first introduced me to my wife, as is related

elsewhere--glancing at the various prints above the familiar names

and marvelling afresh at the endless variations of pattern that they

displayed. At length I came upon two thumb-prints of which one--the

left--was marked by a longitudinal white line--evidently the trace of

a scar; and underneath them was written the signature “Reuben Hornby.”

At this moment Thorndyke re-entered the room carrying the inked slab,

which he laid on the table, and seating him self between the

superintendent and me, addressed the former.

“Now, Miller, here are two thumb-prints made by a gentleman named

Reuben Hornby. Just glance at the left one; it is a highly

characteristic print.”

“Yes,” agreed Miller, “one could swear to that from memory, I should

think.”

“Then look at this.” Thorndyke took the paper from the box and,

unfolding it, handed it to the detective. It bore a pencilled

inscription, and on it were two blood-smears and a very distinct

thumb-print in blood. “What do you say to that thumb-print?”

“Why,” answered Miller, “it’s this one, of course; Reuben Hornby’s

left thumb.”

“Wrong, my friend,” said Thorndyke. “It was made by an ingenious

gentleman named Walter Hornby (whom you followed from the Old Bailey

and lost on Ludgate Hill); but not with his thumb.”

“How, then?” demanded the superintendent incredulously.

“In this way.” Thorndyke took the boxwood “pawn” from its receptacle

and pressed its flat base onto the inked slab; then lifted it and

pressed it onto the back of a visiting-card, and again raised it; and

now the card was marked by a very distinct thumb-print.

“My God!” exclaimed the detective, picking up the card and viewing it

with a stare of dismay, “this is the very devil, sir. This fairly

knocks the bottom out of finger-print identification. May I ask, sir,

how you made that stamp--for I suppose you did make it?”

“Yes, we made it here, and the process we used was practically that

used by photo-engravers in making line blocks; that is to say, we

photographed one of Mr. Hornby’s thumb-prints, printed it on a plate

of chrome-gelatine, developed the plate with hot water and

this”--here he touched the embossed surface of the stamp--“is what

remained. But we could have done it in various other ways; for

instance, with common transfer paper and lithographic stone; indeed,

I assure you, Miller, that there is nothing easier to forge than a

finger-print, and it can be done with such perfection that the forger

himself cannot tell his own forgery from a genuine original, even

when they are placed side by side.”

“Well, I’m hanged,” grunted the superintendent, “you’ve fairly

knocked me, this time, doctor.” He rose gloomily and prepared to

depart. “I suppose,” he added, “your interest in this case has

lapsed, now Belfield’s out of it?”

“Professionally, yes; but I am disposed to finish the case for my own

satisfaction. I am quite curious as to who our too-ingenious friend

may be.”

Miller’s face brightened. “We shall give you every facility, you

know--and that reminds me that Singleton gave me these two

photographs for you, one of the official paper and one of the prints

on the glass. Is there anything more that we can do for you?”

“I should like to have a look at the room in which the murder took

place.”

“You shall, doctor; tomorrow, if you like; I’ll meet you there in the

morning at ten, if that will do.”

It would do excellently, Thorndyke assured him, and with this the

superintendent took his departure in renewed spirits.

We had only just closed the door when there came a hurried and urgent

tapping upon it, whereupon I once more threw it open, and a

quietly-dressed woman in a thick veil, who was standing on the

threshold, stepped quickly past me into the room.

“Where is my husband?” she demanded, as I closed the door; and then,

catching sight of Thorndyke, she strode up to him with a threatening

air and a terrified but angry face.

“What have you done with my husband, sir?” she repeated. “Have you

betrayed him, after giving your word? I met a man who looked like a

police officer on the stairs.”

“Your husband, Mrs. Belfield, is here and quite safe,” replied

Thorndyke. “He has locked himself in that room,” indicating the

office.

Mrs. Belfield darted across and rapped smartly at the door. “Are you

there, Frank?” she called.

In immediate response the key turned, the door opened and Belfield
