CHAPTER XV

THE FINGER-PRINT EXPERTS

The hum of conversation that had been gradually increasing as the court

filled suddenly ceased. A door at the back of the dais was flung open;

counsel, solicitors, and spectators alike rose to their feet; and the

judge entered, closely followed by the Lord Mayor, the sheriff, and

various civic magnates, all picturesque and gorgeous in their robes and

chains of office. The Clerk of Arraigns took his place behind his table

under the dais; the counsel suspended their conversation and fingered

their briefs; and, as the judge took his seat, lawyers, officials, and

spectators took their seats, and all eyes were turned towards the dock.

A few moments later Reuben Hornby appeared in the enclosure in company

with a warder, the two rising, apparently, from the bowels of the earth,

and, stepping forward to the bar, stood with a calm and self-possessed

demeanour, glancing somewhat curiously around the court. For an instant

his eye rested upon the group of friends and well-wishers seated behind

the counsel, and the faintest trace of a smile appeared on his face; but

immediately he turned his eyes away and never again throughout the trial

looked in our direction.

The Clerk of Arraigns now rose and, reading from the indictment which

lay before him on the table, addressed the prisoner--

"Reuben Hornby, you stand indicted for that you did, on the ninth or

tenth day of March, feloniously steal a parcel of diamonds of the goods

and chattels of John Hornby. Are you guilty or not guilty?"

"Not guilty," replied Reuben.

The Clerk of Arraigns, having noted the prisoner's reply, then

proceeded--

"The gentlemen whose names are about to be called will form the jury who

are to try you. If you wish to object to any of them, you must do so as

each comes to the book to be sworn, and before he is sworn. You will

then be heard."

In acknowledgment of this address, which was delivered in clear, ringing

tones, and with remarkable distinctness, Reuben bowed to the clerk, and

the process of swearing-in the jury was commenced, while the counsel

opened their briefs and the judge conversed facetiously with an

official in a fur robe and a massive neck chain.

Very strange, to unaccustomed eyes and ears, was the effect of this

function--half solemn and half grotesque, with an effect intermediate

between that of a religious rite and that of a comic opera. Above the

half-suppressed hum of conversation the clerk's voice arose at regular

intervals, calling out the name of one of the jurymen, and, as its owner

stood up, the court usher, black-gowned and sacerdotal of aspect,

advanced and proffered the book. Then, as the juryman took the volume in

his hand, the voice of the usher resounded through the court like that

of a priest intoning some refrain or antiphon--an effect that was

increased by the rhythmical and archaic character of the formula--

"Samuel Seppings!"

A stolid-looking working-man rose and, taking the Testament in his hand,

stood regarding the usher while that official sang out in a solemn

monotone--

"You shall well and truly try and true deliverance make between our

Sovereign Lord the King and the prisoner at the bar, whom you shall have

in charge, and a true verdict give according to the evidence. So help

you God!"

"James Piper!" Another juryman rose and was given the Book to hold; and

again the monotonous sing-song arose--

"You shall well and truly try and true deliverance make, etc."

"I shall scream aloud if that horrible chant goes on much longer,"

Juliet whispered. "Why don't they all swear at once and have done with

it?"

"That would not meet the requirements," I answered. "However, there are

only two more, so you must have patience."

"And you will have patience with me, too, won't you? I am horribly

frightened. It is all so solemn and dreadful."

"You must try to keep up your courage until Dr. Thorndyke has given his

evidence," I said. "Remember that, until he has spoken, everything is

against Reuben; so be prepared."

"I will try," she answered meekly; "but I can't help being terrified."

The last of the jurymen was at length sworn, and when the clerk had once

more called out the names one by one, the usher counting loudly as each

man answered to his name, the latter officer turned to the Court and

spectators, and proclaimed in solemn tones--

"If anyone can inform my Lords the King's justices, the King's

attorney-general, or the King's serjeant, ere this inquest be now taken

between our Sovereign Lord the King and the prisoner at the bar, of any

treason, murder, felony or misdemeanour, committed or done by him, let

him come forth and he shall be heard; for the prisoner stands at the bar

upon his deliverance."

This proclamation was followed by a profound silence, and after a brief

interval the Clerk of Arraigns turned towards the jury and addressed

them collectively--

"Gentlemen of the jury, the prisoner at the bar stands indicted by the

name of Reuben Hornby, for that he, on the ninth or tenth of March,

feloniously did steal, take and carry away a parcel of diamonds of the

goods of John Hornby. To this indictment he has pleaded that he is not

guilty, and your charge is to inquire whether he be guilty or not and to

hearken to the evidence."

When he had finished his address the clerk sat down, and the judge, a

thin-faced, hollow-eyed elderly man, with bushy grey eyebrows and a very

large nose, looked attentively at Reuben for some moments over the tops

of his gold-rimmed pince-nez. Then he turned towards the counsel nearest

the bench and bowed slightly.

The barrister bowed in return and rose, and for the first time I

obtained a complete view of Sir Hector Trumpler, K.C., the counsel for

the prosecution. His appearance was not prepossessing nor--though he was

a large man and somewhat florid as to his countenance--particularly

striking, except for a general air of untidiness. His gown was slipping

off one shoulder, his wig was perceptibly awry, and his pince-nez

threatened every moment to drop from his nose.

"The case that I have to present to you, my lord and gentlemen of the

jury," he began in a clear, though unmusical voice, "is one the like of

which is but too often met with in this court. It is one in which we

shall see unbounded trust met by treacherous deceit, in which we shall

see countless benefactions rewarded by the basest ingratitude, and in

which we shall witness the deliberate renunciation of a life of

honourable effort in favour of the tortuous and precarious ways of the

criminal. The facts of the case are briefly as follows: The prosecutor

in this case--most unwilling prosecutor, gentlemen--is Mr. John Hornby,

who is a metallurgist and dealer in precious metals. Mr. Hornby has two

nephews, the orphan sons of his two elder brothers, and I may tell you

that since the decease of their parents he has acted the part of a

father to both of them. One of these nephews is Mr. Walter Hornby, and

the other is Reuben Hornby, the prisoner at the bar. Both of these

nephews were received by Mr. Hornby into his business with a view to

their succeeding him when he should retire, and both, I need not say,

occupied positions of trust and responsibility.

"Now, on the evening of the ninth of March there was delivered to Mr.

Hornby a parcel of rough diamonds of which one of his clients asked him

to take charge pending their transfer to the brokers. I need not burden

you with irrelevant details concerning this transaction. It will suffice

to say that the diamonds, which were of the aggregate value of about

thirty thousand pounds, were delivered to him, and the unopened package

deposited by him in his safe, together with a slip of paper on which he

had written in pencil a memorandum of the circumstances. This was on the

evening of the ninth of March, as I have said. Having deposited the

parcel, Mr. Hornby locked the safe, and shortly afterwards left the

premises and went home, taking the keys with him.

"On the following morning, when he unlocked the safe, he perceived with

astonishment and dismay that the parcel of diamonds had vanished. The

slip of paper, however, lay at the bottom of the safe, and on picking it

up Mr. Hornby perceived that it bore a smear of blood, and in addition,

the distinct impression of a human thumb. On this he closed and locked

the safe and sent a note to the police station, in response to which a

very intelligent officer--Inspector Sanderson--came and made a

preliminary examination. I need not follow the case further, since the

details will appear in the evidence, but I may tell you that, in effect,

it has been made clear, beyond all doubt, that the thumb-print on that

paper was the thumb-print of the prisoner, Reuben Hornby."

He paused to adjust his glasses, which were in the very act of falling

from his nose, and hitch up his gown, while he took a leisurely survey

of the jury, as though he were estimating their impressionability. At

this moment I observed Walter Hornby enter the court and take up a

position at the end of our bench nearest the door; and, immediately

after, Superintendent Miller came in and seated himself on one of the

benches opposite.

"The first witness whom I shall call," said Sir Hector Trumpler, "is

John Hornby."

Mr. Hornby, looking wild and agitated, stepped into the witness-box, and

the usher, having handed him the Testament, sang out--

"The evidence you shall give to the court and jury sworn, between our

Sovereign Lord the King and the prisoner at the bar shall be the truth,

the whole truth, and nothing but the truth; so help you God!"

Mr. Hornby kissed the Book, and, casting a glance of unutterable misery

at his nephew, turned towards the counsel.

"Your name is John Hornby, is it not?" asked Sir Hector.

"It is."

"And you occupy premises in St. Mary Axe?"

"Yes. I am a dealer in precious metals, but my business consists

principally in the assaying of samples of ore and quartz and bars of

silver and gold."

"Do you remember what happened on the ninth of March last?"

"Perfectly. My nephew Reuben--the prisoner--delivered to me a parcel of

diamonds which he had received from the purser of the _Elmina Castle_,

to whom I had sent him as my confidential agent. I had intended to

deposit the diamonds with my banker, but when the prisoner arrived at my

office, the banks were already closed, so I had to put the parcel, for

the night, in my own safe. I may say that the prisoner was not in any

way responsible for the delay."

"You are not here to defend the prisoner," said Sir Hector. "Answer my

questions and make no comments, if you please. Was anyone present when

you placed the diamonds in the safe?"

"No one was present but myself."

"I did not ask if you were present when you put them in," said Sir

Hector (whereupon the spectators sniggered and the judge smiled

indulgently). "What else did you do?"

"I wrote in pencil on a leaf of my pocket memorandum block, 'Handed in

by Reuben at 7.3 p.m., 9.3.01,' and initialled it. Then I tore the leaf

from the block and laid it on the parcel, after which I closed the safe

and locked it."

"How soon did you leave the premises after this?"

"Almost immediately. The prisoner was waiting for me in the outer

office--"

"Never mind where the prisoner was; confine your answers to what is

asked. Did you take the keys with you?"

"Yes."

"When did you next open the safe?"

"On the following morning at ten o'clock."

"Was the safe locked or unlocked when you arrived?"

"It was locked. I unlocked it."

"Did you notice anything unusual about the safe?"

"No."

"Had the keys left your custody in the interval?"

"No. They were attached to a key-chain, which I always wear."

"Are there any duplicates of those keys?--the keys of the safe, I mean."

"No, there are no duplicates."

"Have the keys ever gone out of your possession?"

"Yes. If I have had to be absent from the office for a considerable

time, it has been my custom to hand the keys to one of my nephews,

whichever has happened to be in charge at the time."

"And never to any other person?"

"Never to any other person."

"What did you observe when you opened the safe?"

"I observed that the parcel of diamonds had disappeared."

"Did you notice anything else?"

"Yes. I found the leaf from my memorandum block lying at the bottom of

the safe. I picked it up and turned it over, and then saw that there

were smears of blood on it and what looked like the print of a thumb in

blood. The thumb-mark was on the under-surface, as the paper lay at the

bottom of the safe."

"What did you do next?"

"I closed and locked the safe, and sent a note to the police station

saying that a robbery had been committed on my premises."

"You have known the prisoner several years, I believe?"

"Yes; I have known him all his life. He is my eldest brother's son."

"Then you can tell us, no doubt, whether he is left-handed or

right-handed?"

"I should say he was ambidextrous, but he uses his left hand by

preference."

"A fine distinction, Mr. Hornby; a very fine distinction. Now tell me,

did you ascertain beyond all doubt that the diamonds were really gone?"

"Yes; I examined the safe thoroughly, first by myself and afterwards

with the police. There was no doubt that the diamonds had really gone."

"When the detective suggested that you should have the thumb-prints of

your two nephews taken, did you refuse?"

"I refused."

"Why did you refuse?"

"Because I did not choose to subject my nephews to the indignity.

Besides, I had no power to make them submit to the proceeding."

"Had you any suspicions of either of them?"

"I had no suspicions of anyone."

"Kindly examine this piece of paper, Mr. Hornby," said Sir Hector,

passing across a small oblong slip, "and tell us if you recognise it."

Mr. Hornby glanced at the paper for a moment, and then said--

"This is the memorandum slip that I found lying at the bottom of the

safe."

"How do you identify it?"

"By the writing on it, which is in my own hand, and bears my initials."

"Is it the memorandum that you placed on the parcel of diamonds?"

"Yes."

"Was there any thumb-mark or blood-smear on it when you placed it in the

safe?"

"No."

"Was it possible that there could have been any such marks?"

"Quite impossible. I tore it from my memorandum block at the time I

wrote upon it."

"Very well." Sir Hector Trumpler sat down, and Mr. Anstey stood up to

cross-examine the witness.

"You have told us, Mr. Hornby," said he, "that you have known the

prisoner all his life. Now what estimate have you formed of his

character?"

"I have always regarded him as a young man of the highest

character--honourable, truthful, and in every way trustworthy. I have

never, in all my experience of him, known him to deviate a

hair's-breadth from the strictest honour and honesty of conduct."

"You regarded him as a man of irreproachable character. Is that so?"

"That is so; and my opinion of him is unchanged."

"Has he, to your knowledge, any expensive or extravagant habits?"

"No. His habits are simple and rather thrifty."

"Have you ever known him to bet, gamble, or speculate?"

"Never."

"Has he ever seemed to be in want of money?"

"No. He has a small private income, apart from his salary, which I know

he does not spend, since I have occasionally employed my broker to

invest his savings."

"Apart from the thumb-print which was found in the safe, are you aware

of any circumstances that would lead you to suspect the prisoner of

having stolen the diamonds?"

"None whatever."

Mr. Anstey sat down, and as Mr. Hornby left the witness-box, mopping the

perspiration from his forehead, the next witness was called.

"Inspector Sanderson!"

The dapper police officer stepped briskly into the box, and having been

duly sworn, faced the prosecuting counsel with the air of a man who was

prepared for any contingency.

"Do you remember," said Sir Hector, after the usual preliminaries had

been gone through, "what occurred on the morning of the tenth of March?"

"Yes. A note was handed to me at the station at 10.23 a.m. It was from

Mr. John Hornby, and stated that a robbery had occurred at his premises

in St. Mary Axe. I went to the premises and arrived there at 10.31 a.m.

There I saw the prosecutor, Mr. John Hornby, who told me that a parcel

of diamonds had been stolen from the safe. At his request I examined the

safe. There were no signs of its having been forced open; the locks

seemed to be quite uninjured and in good order. Inside the safe, on the

bottom, I found two good-sized drops of blood, and a slip of paper with

pencil-writing on it. The paper bore two blood-smears and a print of a

human thumb in blood."

"Is this the paper?" asked the counsel, passing a small slip across to

the witness.

"Yes," replied the inspector, after a brief glance at the document.

"What did you do next?" "I sent a message to Scotland Yard acquainting

the Chief of the Criminal Investigation Department with the facts, and

then went back to the station. I had no further connection with the

case."

Sir Hector sat down, and the judge glanced at Anstey.

"You tell us," said the latter, rising, "that you observed two

good-sized drops of blood on the bottom of the safe. Did you notice the

condition of the blood, whether moist or dry?"

"The blood looked moist, but I did not touch it. I left it undisturbed

for the detective officers to examine."

The next witness called was Sergeant Bates, of the Criminal

Investigation Department. He stepped into the box with the same ready,

business-like air as the other officer, and, having been sworn,

proceeded to give his evidence with a fluency that suggested careful

preparation, holding an open notebook in his hand but making no

references to it.

"On the tenth of March, at 12.8 p.m., I received instructions to proceed

to St. Mary Axe to inquire into a robbery that had taken place there.

Inspector Sanderson's report was handed to me, and I read it in the cab

on my way to the premises. On arriving at the premises at 12.30 p.m., I

examined the safe carefully. It was quite uninjured, and there were no

marks of any kind upon it. I tested the locks and found them perfect;

there were no marks or indications of any picklock having been used. On

the bottom of the inside I observed two rather large drops of a dark

fluid. I took up some of the fluid on a piece of paper and found it to

be blood. I also found, in the bottom of the safe, the burnt head of a

wax match, and, on searching the floor of the office, I found, close by

the safe, a used wax match from which the head had fallen. I also found

a slip of paper which appeared to have been torn from a perforated

block. On it was written in pencil, 'Handed in by Reuben at 7.3 p.m.

9.3.01. J.H.' There were two smears of blood on the paper and the

impression of a human thumb in blood. I took possession of the paper in

order that it might be examined by the experts. I inspected the office

doors and the outer door of the premises, but found no signs of forcible

entrance on any of them. I questioned the housekeeper, but obtained no

information from him. I then returned to headquarters, made my report

and handed the paper with the marks on it to the Superintendent."

"Is this the paper that you found in the safe?" asked the counsel, once

more handing the leaflet across.

"Yes; this is the paper."

"What happened next?"

"The following afternoon I was sent for by Mr. Singleton, of the

Finger-print Department. He informed me that he had gone through the

files and had not been able to find any thumb-print resembling the one

on the paper, and recommended me to endeavour to obtain prints of the

thumbs of any persons who might have been concerned in the robbery. He

also gave me an enlarged photograph of the thumb-print for reference if

necessary. I accordingly went to St. Mary Axe and had an interview with

Mr. Hornby, when I requested him to allow me to take prints of the

thumbs of all the persons employed on the premises, including his two

nephews. This he refused, saying that he distrusted finger-prints and

that there was no suspicion of anyone on the premises. I asked if he

would allow his nephews to furnish their thumb-prints privately, to

which he replied, 'Certainly not.'"

"Had you then any suspicion of either of the nephews?"

"I thought they were both open to some suspicion. The safe had certainly

been opened with false keys, and as they had both had the real keys in

their possession it was possible that one of them might have taken

impressions in wax and made counterfeit keys."

"Yes."

"I called on Mr. Hornby several times and urged him, for the sake of his

nephews' reputations, to sanction the taking of the thumb-prints; but he

refused very positively and forbade them to submit, although I

understood that they were both willing. It then occurred to me to try if

I could get any help from Mrs. Hornby, and on the fifteenth of March I

called at Mr. Hornby's private house and saw her. I explained to her

what was wanted to clear her nephews from the suspicion that rested on

them, and she then said that she could dispose of those suspicions at

once, for she could show me the thumb-prints of the whole family: she

had them all in a 'Thumbograph.'"

"A 'Thumbograph'?" repeated the judge. "What is a 'Thumbograph'?"

Anstey rose with the little red-covered volume in his hand.

"A 'Thumbograph,' my lord," said he, "is a book, like this, in which

foolish people collect the thumb-prints of their more foolish

acquaintances."

He passed the volume up to the judge, who turned over the leaves

curiously and then nodded to the witness.

"Yes. She said she had them all in a 'Thumbograph.'"

"Then she fetched from a drawer a small red-covered book which she

showed to me. It contained the thumb-prints of all the family and some

of her friends."

"Is this the book?" asked the judge, passing the volume down to the

witness.

The sergeant turned over the leaves until he came to one which he

apparently recognised, and said--

"Yes, m'lord; this is the book. Mrs. Hornby showed me the thumb-prints

of various members of the family, and then found those of the two

nephews. I compared them with the photograph that I had with me and

discovered that the print of the left thumb of Reuben Hornby was in

every respect identical with the thumb-print shown in the photograph."

"What did you do then?"

"I asked Mrs. Hornby to lend me the 'Thumbograph' so that I might show

it to the Chief of the Finger-print Department, to which she consented.

I had not intended to tell her of my discovery, but, as I was leaving,

Mr. Hornby arrived home, and when he heard of what had taken place, he

asked me why I wanted the book, and then I told him. He was greatly

astonished and horrified, and wished me to return the book at once. He

proposed to let the whole matter drop and take the loss of the diamonds

on himself; but I pointed out that this was impossible as it would

practically amount to compounding a felony. Seeing that Mrs. Hornby was

so distressed at the idea of her book being used in evidence against her

nephew, I promised her that I would return it to her if I could obtain a

thumb-print in any other way.

"I then took the 'Thumbograph' to Scotland Yard and showed it to Mr.

Singleton, who agreed that the print of the left thumb of Reuben Hornby

was in every respect identical with the thumb-print on the paper found

in the safe. On this I applied for a warrant for the arrest of Reuben

Hornby, which I executed on the following morning. I told the prisoner

what I had promised Mrs. Hornby, and he then offered to allow me to take

a print of his left thumb so that his aunt's book should not have to be

used in evidence."

"How is it, then," asked the judge, "that it has been put in evidence?"

"It has been put in by the defence, my lord," said Sir Hector Trumpler.

"I see," said the judge. "'A hair of the dog that bit him.' The

'Thumbograph' is to be applied as a remedy on the principle that

_similia similibus curantur_. Well?"

"When I arrested him, I administered the usual caution, and the prisoner

then said, 'I am innocent. I know nothing about the robbery.'"

The counsel for the prosecution sat down, and Anstey rose to

cross-examine.

"You have told us," said he, in his clear musical voice, "that you found

at the bottom of the safe two rather large drops of a dark fluid which

you considered to be blood. Now, what led you to believe that fluid to

be blood?"

"I took some of the fluid up on a piece of white paper, and it had the

appearance and colour of blood."

"Was it examined microscopically or otherwise?"

"Not to my knowledge."

"Was it quite liquid?"

"Yes, I should say quite liquid."

"What appearance had it on paper?"

"It looked like a clear red liquid of the colour of blood, and was

rather thick and sticky."

Anstey sat down, and the next witness, an elderly man, answering to the

name of Francis Simmons, was called.

"You are the housekeeper at Mr. Hornby's premises in St. Mary Axe?"

asked Sir Hector Trumpler.

"I am."

"Did you notice anything unusual on the night of the ninth of March?"

"I did not."

"Did you make your usual rounds on that occasion?"

"Yes. I went all over the premises several times during the night, and

the rest of the time I was in a room over the private office."

"Who arrived first on the morning of the tenth?"

"Mr. Reuben. He arrived about twenty minutes before anybody else."

"What part of the building did he go to?"

"He went into the private office, which I opened for him. He remained

there until a few minutes before Mr. Hornby arrived, when he went up to

the laboratory."

"Who came next?"

"Mr. Hornby, and Mr. Walter came in just after him."

The counsel sat down, and Anstey proceeded to cross-examine the witness.

"Who was the last to leave the premises on the evening of the ninth?"

"I am not sure."

"Why are you not sure?"

"I had to take a note and a parcel to a firm in Shoreditch. When I

started, a clerk named Thomas Holker was in the outer office and Mr.

Walter Hornby was in the private office. When I returned they had both

gone."

"Was the outer door locked?"

"Yes."

"Had Holker a key of the outer door?"

"No. Mr. Hornby and his two nephews had each a key, and I have one. No

one else had a key."

"How long were you absent?"

"About three-quarters of an hour."

"Who gave you the note and the parcel?"

"Mr. Walter Hornby."

"When did he give them to you?"

"He gave them to me just before I started, and told me to go at once for

fear the place should be closed before I got there."

"And was the place closed?"

"Yes. It was all shut up, and everybody had gone."

Anstey resumed his seat, the witness shuffled out of the box with an air

of evident relief, and the usher called out, "Henry James Singleton."

Mr. Singleton rose from his seat at the table by the solicitors for the

prosecution and entered the box. Sir Hector adjusted his glasses, turned

over a page of his brief, and cast a steady and impressive glance at the

jury.

"I believe, Mr. Singleton," he said at length, "that you are connected

with the Finger-print Department at Scotland Yard?"

"Yes. I am one of the chief assistants in that department."

"What are your official duties?"

"My principal occupation consists in the examination and comparison of

the finger-prints of criminals and suspected persons. These

finger-prints are classified by me according to their characters and

arranged in files for reference."

"I take it that you have examined a great number of finger-prints?"

"I have examined many thousands of finger-prints, and have studied them

closely for purposes of identification."

"Kindly examine this paper, Mr. Singleton" (here the fatal leaflet was

handed to him by the usher); "have you ever seen it before?"

"Yes. It was handed to me for examination at my office on the tenth of

March."

"There is a mark upon it--the print of a finger or thumb. Can you tell

us anything about that mark?"

"It is the print of the left thumb of Reuben Hornby, the prisoner at

the bar."

"You are quite sure of that?"

"I am quite sure."

"Do you swear that the mark upon that paper was made by the thumb of the

prisoner?"

"I do."

"Could it not have been made by the thumb of some other person?"

"No; it is impossible that it could have been made by any other person."

At this moment I felt Juliet lay a trembling hand on mine, and, glancing

at her, I saw that she was deathly pale. I took her hand in mine and,

pressing it gently, whispered to her, "Have courage; there is nothing

unexpected in this."

"Thank you," she whispered in reply, with a faint smile; "I will try;

but it is all so horribly unnerving."

"You consider," Sir Hector proceeded, "that the identity of this

thumb-print admits of no doubt?" "It admits of no doubt whatever,"

replied Mr. Singleton.

"Can you explain to us, without being too technical, how you have

arrived at such complete certainty?"

"I myself took a print of the prisoner's thumb--having first obtained

the prisoner's consent after warning him that the print would be used in

evidence against him--and I compared that print with the mark on this

paper. The comparison was made with the greatest care and by the most

approved method, point by point and detail by detail, and the two prints

were found to be identical in every respect.

"Now it has been proved by exact calculations--which calculations I have

personally verified---that the chance that the print of a single finger

of any given person will be exactly like the print of the same finger of

any other given person is as one to sixty-four thousand millions. That

is to say that, since the number of the entire human race is about

sixteen hundred millions, the chance is about one to four that the

print of a single finger of any one person will be identical with that

of the same finger of any other member of the human race.

"It has been said by a great authority--and I entirely agree with the

statement--that a complete, or nearly complete, accordance between two

prints of a single finger affords evidence requiring no corroboration

that the persons from whom they were made are the same.

"Now, these calculations apply to the prints of ordinary and normal

fingers or thumbs. But the thumb from which these prints were taken is

not ordinary or normal. There is upon it a deep but clean linear

scar--the scar of an old incised wound--and this scar passes across the

pattern of the ridges, intersecting the latter at certain places and

disturbing their continuity at others. Now this very characteristic scar

is an additional feature, having a set of chances of its own. So that we

have to consider not only the chance that the print of the prisoner's

left thumb should be identical with the print of some other person's

left thumb--which is as one to sixty-four thousand millions--but the

further chance that these two identical thumb-prints should be traversed

by the impression of a scar identical in size and appearance, and

intersecting the ridges at exactly the same places and producing

failures of continuity in the ridges of exactly the same character. But

these two chances, multiplied into one another, yield an ultimate chance

of about one to four thousand trillions that the prisoner's left thumb

will exactly resemble the print of some other person's thumb, both as to

the pattern and the scar which crosses the pattern; in other words such

a coincidence is an utter impossibility."

Sir Hector Trumpler took off his glasses and looked long and steadily at

the jury as though he should say, "Come, my friends; what do you think

of that?" Then he sat down with a jerk and turned towards Anstey and

Thorndyke with a look of triumph.

"Do you propose to cross-examine the witness?" inquired the judge,

seeing that the counsel for the defence made no sign.

"No, my lord," replied Anstey.

Thereupon Sir Hector Trumpler turned once more towards the defending

counsel, and his broad, red face was illumined by a smile of deep

satisfaction. That smile was reflected on the face of Mr. Singleton as

he stepped from the box, and, as I glanced at Thorndyke, I seemed to

detect, for a single instant, on his calm and immovable countenance, the

faintest shadow of a smile.

"Herbert John Nash!"

A plump, middle-aged man, of keen, though studious, aspect, stepped into

the box, and Sir Hector rose once more.

"You are one of the chief assistants in the Finger-print Department, I

believe, Mr. Nash?"

"I am."

"Have you heard the evidence of the last witness?"

"I have."

"Do you agree with the statements made by that witness?"

"Entirely. I am prepared to swear that the print on the paper found in

the safe is that of the left thumb of the prisoner, Reuben Hornby."

"And you are certain that no mistake is possible?"

"I am certain that no mistake is possible."

Again Sir Hector glanced significantly at the jury as he resumed his

seat, and again Anstey made no sign beyond the entry of a few notes on

the margin of his brief.

"Are you calling any more witnesses?" asked the judge, dipping his pen

in the ink.

"No, my lord," replied Sir Hector. "That is our case."

Upon this Anstey rose and, addressing the judge, said--

"I call witnesses, my lord."

The judge nodded and made an entry in his notes while Anstey delivered

his brief introductory speech--

"My lord and gentlemen of the jury, I shall not occupy the time of the

Court with unnecessary appeals at this stage, but shall proceed to take

the evidence of my witnesses without delay."

There was a pause of a minute or more, during which the silence was

broken only by the rustle of papers and the squeaking of the judge's

quill pen. Juliet turned a white, scared face to me and said in a hushed

whisper--

"This is terrible. That last man's evidence is perfectly crushing. What

can possibly be said in reply? I am in despair; oh! poor Reuben! He is

lost, Dr. Jervis! He hasn't a chance now."

"Do you believe that he is guilty?" I asked.

"Certainly not!" she replied indignantly. "I am as certain of his

innocence as ever."

"Then," said I, "if he is innocent, there must be some means of proving

his innocence."

"Yes. I suppose so," she rejoined in a dejected whisper. "At any rate we

shall soon know now."

At this moment the usher's voice was heard calling out the name of the

first witness for the defence.

"Edmund Horford Rowe!"

A keen-looking, grey-haired man, with a shaven face and close-cut

side-whiskers, stepped into the box and was sworn in due form.

"You are a doctor of medicine, I believe," said Anstey, addressing the

witness, "and lecturer on Medical Jurisprudence at the South London

Hospital?"

"I am."

"Have you had occasion to study the properties of blood?"

"Yes. The properties of blood are of great importance from a

medico-legal point of view."

"Can you tell us what happens when a drop of blood--say from a cut

finger--falls upon a surface such as the bottom of an iron safe?"

"A drop of blood from a living body falling upon any non-absorbent

surface will, in the course of a few minutes, solidify into a jelly

which will, at first, have the same bulk and colour as the liquid

blood."

"Will it undergo any further change?"

"Yes. In a few minutes more the jelly will begin to shrink and become

more solid so that the blood will become separated into two parts, the

solid and the liquid. The solid part will consist of a firm, tough jelly

of a deep red colour, and the liquid part will consist of a pale yellow,

clear, watery liquid."

"At the end, say, of two hours, what will be the condition of the drop

of blood?"

"It will consist of a drop of clear, nearly colourless liquid, in the

middle of which will be a small, tough, red clot."

"Supposing such a drop to be taken up on a piece of white paper, what

would be its appearance?"

"The paper would be wetted by the colourless liquid, and the solid clot

would probably adhere to the paper in a mass."

"Would the blood on the paper appear as a clear, red liquid?"

"Certainly not. The liquid would appear like water, and the clot would

appear as a solid mass sticking to the paper."

"Does blood always behave in the way you have described?"

"Always, unless some artificial means are taken to prevent it from

clotting."

"By what means can blood be prevented from clotting or solidifying?"

"There are two principal methods. One is to stir or whip the fresh blood

rapidly with a bundle of fine twigs. When this is done, the fibrin--the

part of the blood that causes solidification--adheres to the twigs, and

the blood that remains, though it is unchanged in appearance, will

remain liquid for an indefinite time. The other method is to dissolve a

certain proportion of some alkaline salt in the fresh blood, after which

it no longer has any tendency to solidify."

"You have heard the evidence of Inspector Sanderson and Sergeant Bates?"

"Yes."

"Inspector Sanderson has told us that he examined the safe at 10.31 a.m.

and found two good-sized drops of blood on the bottom. Sergeant Bates

has told us that he examined the safe two hours later, and that he took

up one of the drops of blood on a piece of white paper. The blood was

then quite liquid, and, on the paper, it looked like a clear, red liquid

of the colour of blood. What should you consider the condition and

nature of that blood to have been?"

"If it was really blood at all, I should say that it was either

defibrinated blood--that is, blood from which the fibrin has been

extracted by whipping--or that it had been treated with an alkaline

salt."

"You are of opinion that the blood found in the safe could not have been

ordinary blood shed from a cut or wound?"

"I am sure it could not have been."

"Now, Dr. Rowe, I am going to ask you a few questions on another

subject. Have you given any attention to finger-prints made by bloody

fingers?"

"Yes. I have recently made some experiments on the subject."

"Will you give us the results of those experiments?"

"My object was to ascertain whether fingers wet with fresh blood would

yield distinct and characteristic prints. I made a great number of

trials, and as a result found that it is extremely difficult to obtain a

clear print when the finger is wetted with fresh blood. The usual result

is a mere red blot showing no ridge pattern at all, owing to the blood

filling the furrows between the ridges. But if the blood is allowed to

dry almost completely on the finger, a very clear print is obtained."

"Is it possible to recognise a print that has been made by a nearly dry

finger?"

"Yes; quite easily. The half-dried blood is nearly solid and adheres to

the paper in a different way from the liquid, and it shows minute

details, such as the mouths of the sweat glands, which are always

obliterated by the liquid."

"Look carefully at this paper, which was found in the safe, and tell me

what you see."

The witness took the paper and examined it attentively, first with the

naked eye and then with a pocket-lens.

"I see," said he, "two blood-marks and a print, apparently of a thumb.

Of the two marks, one is a blot, smeared slightly by a finger or thumb;

the other is a smear only. Both were evidently produced with quite

liquid blood. The thumb-print was also made with liquid blood."

"You are quite sure that the thumb-print was made with liquid blood?"

"Quite sure."

"Is there anything unusual about the thumb-print?"

"Yes. It is extraordinarily clear and distinct. I have made a great

number of trials and have endeavoured to obtain the clearest prints

possible with fresh blood; but none of my prints are nearly as distinct

as this one."

Here the witness produced a number of sheets of paper, each of which was

covered with the prints of bloody fingers, and compared them with the

memorandum slip.

The papers were handed to the judge for his inspection, and Anstey sat

down, when Sir Hector Trumpler rose, with a somewhat puzzled expression

on his face, to cross-examine.

"You say that the blood found in the safe was defibrinated or

artificially treated. What inference do you draw from that fact?"

"I infer that it was not dropped from a bleeding wound."

"Can you form any idea how such blood should have got into the safe?"

"None whatever."

"You say that the thumb-print is a remarkably distinct one. What

conclusion do you draw from that?"

"I do not draw any conclusion. I cannot account for its distinctness at

all."

The learned counsel sat down with rather a baffled air, and I observed a

faint smile spread over the countenance of my colleague.

"Arabella Hornby."

A muffled whimpering from my neighbour on the left hand was accompanied

by a wild rustling of silk. Glancing at Mrs. Hornby, I saw her stagger

from the bench, shaking like a jelly, mopping her eyes with her

handkerchief and grasping her open purse. She entered the witness-box,

and, having gazed wildly round the court, began to search the

multitudinous compartments of her purse.

"The evidence you shall give," sang out the usher--whereat Mrs. Hornby

paused in her search and stared at him apprehensively--"to the court and

jury sworn, between our Sovereign Lord the King and the prisoner at the

bar shall be the truth,--"

"Certainly," said Mrs. Hornby stiffly, "I--"

"--the whole truth, and nothing but the truth; so help you God!"

He held out the Testament, which she took from him with a trembling hand

and forthwith dropped with a resounding bang on to the floor of the

witness-box, diving after it with such precipitancy that her bonnet

jammed violently against the rail of the box.

She disappeared from view for a moment, and then rose from the depths

with a purple face and her bonnet flattened and cocked over one ear like

an artillery-man's forage cap.

"Kiss the Book, if you please," said the usher, suppressing a grin by an

heroic effort, as Mrs. Hornby, encumbered by her purse, her handkerchief

and the Testament, struggled to unfasten her bonnet-strings. She clawed

frantically at her bonnet, and, having dusted the Testament with her

handkerchief, kissed it tenderly and laid it on the rail of the box,

whence it fell instantly on to the floor of the court.

"I am really very sorry!" exclaimed Mrs. Hornby, leaning over the rail

to address the usher as he stooped to pick up the Book, and discharging

on to his back a stream of coins, buttons and folded bills from her open

purse; "you will think me very awkward, I'm afraid."

She mopped her face and replaced her bonnet rakishly on one side, as

Anstey rose and passed a small red book across to her.

"Kindly look at that book, Mrs. Hornby."

"I'd rather not," said she, with a gesture of repugnance. "It is

associated with matters of so extremely disagreeable a character--"

"Do you recognise it?"

"Do I recognise it! How can you ask me such a question when you must

know--"

"Answer the question," interposed the judge. "Do you or do you not

recognise the book in your hand?"

"Of course I recognise it. How could I fail to--"

"Then say so," said the judge.

"I have said so," retorted Mrs. Hornby indignantly.

The judge nodded to Anstey, who then continued--"It is called a

'Thumbograph,' I believe."

"Yes: the name 'Thumbograph' is printed on the cover, so I suppose that

is what it is called."

"Will you tell us, Mrs. Hornby, how the 'Thumbograph' came into your

possession?"

For one moment Mrs. Hornby stared wildly at her interrogator; then she

snatched a paper from her purse, unfolded it, gazed at it with an

expression of dismay, and crumpled it up in the palm of her hand.

"You are asked a question," said the judge.

"Oh! yes," said Mrs. Hornby. "The Committee of the Society--no, that is

the wrong one--I mean Walter, you know--at least--"

"I beg your pardon," said Anstey, with polite gravity.

"You were speaking of the committee of some society," interposed the

judge. "What society were you referring to?"

Mrs. Hornby spread out the paper and, after a glance at it, replied--

"The Society of Paralysed Idiots, your worship," whereat a rumble of

suppressed laughter arose from the gallery.

"But what has that society to do with the 'Thumbograph'?" inquired the

judge.

"Nothing, your worship. Nothing at all."

"Then why did you refer to it?"

"I am sure I don't know," said Mrs. Hornby, wiping her eyes with the

paper and then hastily exchanging it for her handkerchief.

The judge took off his glasses and gazed at Mrs. Hornby with an

expression of bewilderment. Then he turned to the counsel and said in a

weary voice--"Proceed, if you please, Mr. Anstey."

"Can you tell us, Mrs. Hornby, how the 'Thumbograph' came into your

possession?" said the latter in persuasive accents.

"I thought it was Walter, and so did my niece, but Walter says it was

not, and he ought to know, being young and having a most excellent

memory, as I had myself when I was his age, and really, you know, it

can't possibly matter where I got the thing--"

"But it does matter," interrupted Anstey. "We wish particularly to

know."

"If you mean that you wish to get one like it--"

"We do not," said Anstey. "We wish to know how that particular

'Thumbograph' came into your possession. Did you, for instance, buy it

yourself, or was it given to you by someone?"

"Walter says I bought it myself, but I thought he gave it to me, but he

says he did not, and you see--"

"Never mind what Walter says. What is your own impression?"

"Why I still think that he gave it to me, though, of course, seeing that

my memory is not what it was--"

"You think that Walter gave it to you?"

"Yes, in fact I feel sure he did, and so does my niece."

"Walter is your nephew, Walter Hornby?"

"Yes, of course. I thought you knew."

"Can you recall the occasion on which the 'Thumbograph' was given to

you?"

"Oh yes, quite distinctly. We had some people to dinner--some people

named Colley--not the Dorsetshire Colleys, you know, although they are

exceedingly nice people, as I have no doubt the other Colleys are, too,

when you know them, but we don't. Well, after dinner we were a little

dull and rather at a loss, because Juliet, my niece, you know, had cut

her finger and couldn't play the piano excepting with the left hand, and

that is so monotonous as well as fatiguing, and the Colleys are not

musical, excepting Adolphus, who plays the trombone, but he hadn't got

it with him, and then, fortunately, Walter came in and brought the

'Thumbograph' and took all our thumb-prints and his own as well, and we

were very much amused, and Matilda Colley--that is the eldest daughter

but one--said that Reuben jogged her elbow, but that was only an

excuse--"

"Exactly," interrupted Anstey. "And you recollect quite clearly that

your nephew Walter gave you the 'Thumbograph' on that occasion?"

"Oh, distinctly; though, you know, he is really my husband's nephew--"

"Yes. And you are sure that he took the thumb-prints?"

"Quite sure."

"And you are sure that you never saw the 'Thumbograph' before that?"

"Never. How could I? He hadn't brought it."

"Have you ever lent the 'Thumbograph' to anyone?"

"No, never. No one has ever wanted to borrow it, because, you see--"

"Has it never, at any time, gone out of your possession?"

"Oh, I wouldn't say that; in fact, I have often thought, though I hate

suspecting people, and I really don't suspect anybody in particular, you

know, but it certainly was very peculiar and I can't explain it in any

other way. You see, I kept the 'Thumbograph' in a drawer in my writing

table, and in the same drawer I used to keep my handkerchief-bag--in

fact I do still, and it is there at this very moment, for in my hurry

and agitation, I forgot about it until we were in the cab, and then it

was too late, because Mr. Lawley--"

"Yes. You kept it in a drawer with your handkerchief-bag."

"That was what I said. Well, when Mr. Hornby was staying at Brighton he

wrote to ask me to go down for a week and bring Juliet--Miss Gibson, you

know--with me. So we went, and, just as we were starting, I sent Juliet

to fetch my handkerchief-bag from the drawer, and I said to her,

'Perhaps we might take the thumb-book with us; it might come in useful

on a wet day.' So she went, and presently she came back and said that

the 'Thumbograph' was not in the drawer. Well, I was so surprised that I

went back with her and looked myself, and sure enough the drawer was

empty. Well, I didn't think much of it at the time, but when we came

home again, as soon as we got out of the cab, I gave Juliet my

handkerchief-bag to put away, and presently she came running to me in a

great state of excitement. 'Why, Auntie,' she said,' the "Thumbograph"

is in the drawer; somebody must have been meddling with your writing

table.' I went with her to the drawer, and there, sure enough, was the

'Thumbograph.' Somebody must have taken it out and put it back while we

were away."

"Who could have had access to your writing table?"

"Oh, anybody, because, you see, the drawers were never locked. We

thought it must have been one of the servants."

"Had anyone been to the house during your absence?"

"No. Nobody, except, of course, my two nephews; and neither of them had

touched it, because we asked them, and they both said they had not."

"Thank you." Anstey sat down, and Mrs. Hornby having given another

correcting twist to her bonnet, was about to step down from the box when

Sir Hector rose and bestowed upon her an intimidating stare.

"You made some reference," said he, "to a society--the Society of

Paralysed Idiots, I think, whatever that may be. Now what caused you to

make that reference?"

"It was a mistake; I was thinking of something else."

"I know it was a mistake. You referred to a paper that was in your

hand."

"I did not refer to it, I merely looked at it. It is a letter from the

Society of Paralysed Idiots. It is nothing to do with me really, you

know; I don't belong to the society, or anything of that sort."

"Did you mistake that paper for some other paper?"

"Yes, I took it for a paper with some notes on it to assist my memory."

"What kind of notes?"

"Oh, just the questions I was likely to be asked."

"Were the answers that you were to give to those questions also written

on the paper?"

"Of course they were. The questions would not have been any use without

the answers."

"Have you been asked the questions that were written on the paper?"

"Yes; at least, some of them."

"Have you given the answers that were written down?"

"I don't think I have--in fact, I am sure I haven't, because, you see--"

"Ah! you don't think you have." Sir Hector Trumpler smiled significantly

at the jury, and continued--

"Now who wrote down those questions and answers?"

"My nephew, Walter Hornby. He thought, you know--"

"Never mind what he thought. Who advised or instructed him to write them

down?"

"Nobody. It was entirely his own idea, and very thoughtful of him, too,

though Dr. Jervis took the paper away from me and said I must rely on my

memory."

Sir Hector was evidently rather taken aback by this answer, and sat down

suddenly, with a distinctly chapfallen air.

"Where is this paper on which the questions and answers are written?"

asked the judge. In anticipation of this inquiry I had already handed it

to Thorndyke, and had noted by the significant glance that he bestowed

on me that he had not failed to observe the peculiarity in the type.

Indeed the matter was presently put beyond all doubt, for he hastily

passed to me a scrap of paper, on which I found, when I opened it out,

that he had written "X = W.H."

As Anstey handed the rather questionable document up to the judge, I

glanced at Walter Hornby and observed him to flush angrily, though he

strove to appear calm and unconcerned, and the look that he directed at

his aunt was very much the reverse of benevolent.

"Is this the paper?" asked the judge, passing it down to the witness.

"Yes, your worship," answered Mrs. Hornby, in a tremulous voice;

whereupon the document was returned to the judge, who proceeded to

compare it with his notes.

"I shall order this document to be impounded," said he sternly, after

making a brief comparison. "There has been a distinct attempt to tamper

with witnesses. Proceed with your case, Mr. Anstey."

There was a brief pause, during which Mrs. Hornby tottered across the

court and resumed her seat, gasping with excitement and relief; then the

usher called out--

"John Evelyn Thorndyke!"

"Thank God!" exclaimed Juliet, clasping her hands. "Oh! will he be able

to save Reuben? Do you think he will, Dr. Jervis?"

"There is someone who thinks he will," I replied, glancing towards

Polton, who, clasping in his arms the mysterious box and holding on to

the microscope case, gazed at his master with a smile of ecstasy.

"Polton has more faith than you have, Miss Gibson."

"Yes, the dear, faithful little man!" she rejoined. "Well, we shall know

the worst very soon now, at any rate."

"The worst or the best," I said. "We are now going to hear what the

defence really is."

"God grant that it may be a good defence," she exclaimed in a low voice;

and I--though not ordinarily a religious man--murmured "Amen!"
