Every movement made by a travelling criminal is recorded in the "Circular." Men who have found themselves too closely watched by the Bristol police may, for example, hope to find Cardiff less vigilant. But the "Ill.u.s.trated Circular" tells of their departure from Bristol, and Cardiff is on the alert. There is little hope of escape from that all-pervading vigilance.

The _Police Gazette_, too, is issued by this department twice a week, not only to all the police forces of the kingdom, but to the Colonies and the nearest European countries. This is the latest police move to checkmate the operations of the more widely travelling rogues.

No less important are the "Special Release Notices" or, as it is now called, the _Weekly List of Habitual Criminals_. Since 1896 prison officials have furnished to Scotland Yard, every week, a list of prisoners about to be released who are habitual criminals. This list, which gives a detailed description of each man, and his index number in the records, is sent to every police force in the country. It is so made easy to draw a conclusion should an outbreak of burglaries commence in a district wherein a burglar has lately been released.

In a corner of one room in Scotland Yard is piled a miscellaneous heap of thieves' equipment--jemmies, chisels, scientific safe-breaking implements, and other oddments. The office periodically destroys these, though their fas.h.i.+oning has probably cost skilled workmen much time and trouble. Only a new invention is spared, and that so that it may be placed in the Black Museum for instructive purposes.

In other rooms is kept the personal property of the prisoners still undergoing sentence. It was, I think, David Harum who remarked that there was as much human nature in some folks as there is in others--if not more. A glance round this mixed a.s.sortment proves the truth of the truism.



A bag of golf clubs, a fis.h.i.+ng rod, cameras, books, clothes, rings, watches, jewellery--all give an index to the temperament of the individual owning them. Money, too, is often kept here by the wish of the convicts themselves. Personal belongings are restored at the expiration of a sentence, but valuable articles--and many find their way to the store-room--are not restored except on absolute proof of owners.h.i.+p. When a claim is doubtful the matter is referred to a magistrate, and on his order the disposal of the property rests.

The department plays no small part in tightening the meshes of the net that keeps evil-doers within bounds. It does its duty with kindliness, but without fear or favour; but the difficulties of the work are so enormous that they could hardly be exaggerated.

CHAPTER VIII.

FINGER-PRINTS.

Once upon a time a wily burglar sat in his cell at Brixton awaiting trial. He knew that conviction for his latest escapade was inevitable.

That troubled him little. As he would probably have said, he could do the sentence he was likely to get for a first offence "on his head." But it was by no means a first offence. Stored away at Scotland Yard was a long list of little affairs in which he had been concerned which would not incline the judge to leniency.

John Smith--that is not his real name, but it will serve--knew that presently warders would ask him to press inky fingers on a white sheet of paper, so that the resulting prints should be sent to Scotland Yard.

Inevitably then his previous ill-doings would be disclosed. They might make all the difference between a nominal sentence as a first offender and five years' penal servitude as an habitual criminal, to say nothing of police supervision afterwards.

John Smith thought hard, and at last got an idea. He broke a tag from his boot-lace and began to skin the tips of his fingers until, as he thought, every trace of a pattern by which he could be identified had been obliterated.

Notwithstanding his bleeding hands, he smiled cheerfully when he was reported for prison hospital treatment. The sequel affords a saddening reflection on misplaced ingenuity and endurance. He had only penetrated the outer skin, and it began to grow again.

They nursed his bandaged hands with infinite care, for a conclusion as to his record had become obvious. And then officers took his prints after all--and discovered that he was none other than Bill Brown, with a criminal history to which an Old Bailey judge listened with unaffected interest. Bill--or John--got his five years after all.

I have told this little story because it affords an excellent ill.u.s.tration of the work of the finger-print department at Scotland Yard--a department which serves not only the Metropolitan Police, but every police force in the kingdom.

There is a great deal of confusion in the public mind between Bertillonage and the finger-print system. Even responsible London newspapers fell into the error, when M. Bertillon died, of ascribing to him the invention of the system--with which he had nothing to do.

To many people has been ascribed the discovery that finger-prints are an infallible method of identification. The knowledge however was of little use till the inventive genius of one man worked out a simple method of cla.s.sification for police purposes, so that prints could be compared almost instantly with those on record. That man was Sir Edward Henry, long before he came to Scotland Yard, when he was in the Indian police service.

The Henry system has almost entirely superseded the Bertillon system throughout the world, and there is little doubt that it will ultimately become universal. Thousands of criminals who would otherwise have escaped a full measure of punishment for their misdeeds curse its author. It is in this department that police science has been brought to its highest pitch of perfection--a perfection begot of organisation.

Every prisoner for a month or longer nowadays has his prints taken a little before he is discharged. These prints, if they are not already in the records of Scotland Yard, are added to them, and a number gives the key to the man's record in the Habitual Criminals Registry.

In this manner there has acc.u.mulated since 1901, when the system was first put in force, a collection of more than two hundred thousand prints. It is all a matter of system, of scientific and literal exactness, and there is no margin of error. A mistake in identification by finger-prints is literally impossible.

As everyone knows, the ridges at the tips of the fingers maintain their formation from birth to death, and even after. Nothing can change them.

It is a possibility, though I believe it has never been known to happen, that there are two people in the world who have the markings on one finger-tip exactly alike. But even that incredible chance is guarded against, by taking the markings of the whole ten fingers. It will be realised how great a miracle it would be for two persons to have exactly the same lines, broken in exactly the same way, in exactly the same order on their two hands. That fact is the root principle of the finger-print work.

It is necessary to point out that the existence of the department is not so much for the purpose of detecting crime as of detecting criminals. In the administration of justice a judge takes the past career of a prisoner into consideration when pa.s.sing sentence. The main work of the department is to furnish the clue to a past career by scrutinising the finger-prints of persons on remand to discover whether they are habitual criminals or not.

A thousand aliases will not help a man, no change of appearance, no protestations of mistake, if his prints correspond with those in the files. But it is all so simply done. There is nothing spectacular, nothing imposing about the process. Practically all that is needed is a piece of tin, some printer's ink, and a sheet of paper. Within a few minutes afterwards his record can be known.

Compare this with the old Bertillon system of anthropometric measurements. Bertillon's system depends on the fact that after a person reaches maturity certain portions of the body are always the same in measurement. The theory is sound, but the difficulties in the way of applying it are immense.

In his book Sir Edward Henry has pointed out the defects of the system.

The instruments are costly, measurers have to be specially trained, and even so may make a mistake--an error of two twenty-fifths of an inch will prevent identification--the search among the records may take an hour or more, and, moreover, through carelessness or inattention, the whole data may be wrong. For six years--from 1895 to 1901--this system was in force at Scotland Yard. The maximum number of identifications in any one year was 500. In 1913, by the aid of finger-prints, 10,607 persons were identified.

Roughly, it is all a matter of cla.s.sification into "arches," "loops,"

"whorls," and "composites." It is intricate to describe, but simple to carry out. To the uninitiated it inevitably suggests the old problem "think of a number, double it--."

What happens is this: Every print for primary cla.s.sification purposes is considered as a loop or a whorl. The fingers are taken in pairs and put down something like this:

L. L. W. L. L.

-------------------- L. W. W. W. W.

Now a whorl occurring in the first pair would count sixteen, in the second, eight, and so on. The loops are ignored. Consequently, the number in the above formula is:

0. 0. 4. 0. 0.

---------------- 0. 8. 4. 2. 1.

These are added together and become 4-15. The figure 1 is added above and below, and the searcher knows that he has to look for the record he wants in the sixteenth file of Number 5 horizontal row in a cabinet specially arranged.

Of course, sub-cla.s.sification is carried much farther than this, but it is scarcely necessary to elaborate the point.

Day by day, the prison governors from all parts of the country are sending in records to be added to the files, and police authorities, also from all parts of the country, are asking for prisoners to be identified.

An interesting story concerns two men whom we will call Robinson and Jones, who were tried for different offences the same day. Robinson was rich; Jones was not. Robinson received a long sentence, Jones a light one.

Probably they arranged it all in the prison van, but anyhow, when they reached the gaol they had changed ident.i.ties--and sentences. All went well until a short time before the _soi-disant_ Jones was due to be released. Then his finger-prints were taken, compared with those of Jones in the files, and found not to correspond.

Half an hour later wires were being exchanged between Scotland Yard and the prison, and, to the mutual consternation of the two men, the little scheme was revealed. Finger-prints had outwitted them.

Save for a few filing cabinets stretching from floor to ceiling in a well-lighted room, there is little apparent difference between the Finger-print Department at Scotland Yard and the interior of an ordinary City office. Men pore over foolscap sheets of paper with magnifying gla.s.ses, comparing, cla.s.sifying, and checking, day in, day out.

They are all detectives, but their work is specialist work, totally different to that of the bulk of the men of the C.I.D. It may be that sometimes they realise that a man's life or liberty depends on their scrutiny, but for the most part they do their work with cold deliberation and machine-like precision. Is one set of finger-marks identical with another? That is all they have to answer. It is the pride of the department that since it has been established it has never made a mistake.

At its head is Chief Detective Inspector Charles Collins, an enthusiast in identification work, who has seen the system change from the old days when detectives paid periodical visits to Holloway Prison to see if they could recognise prisoners on remand, and when profile and full-face photographs were used for the records, to that now in use which he has had no small share in bringing to its high state of efficiency.

He can read a finger-print as other men can read a letter, and has even, for the purposes of study, taken prints of the fingers of monkeys at the Zoo. Many times has he given evidence as an expert in cases where finger-prints have formed part of the evidence. His cold, scientific a.n.a.lysis has always convinced the most sceptical, and always a conviction has followed.

He wrote the chapter dealing with the photographing and enlarging of finger-prints in Sir Edward Henry's standard work on the subject, and is something of a magician in the way he can detect a mark when none is obvious to the naked eye.

I have seen a man press his fingers on a clean sheet of paper, apparently without leaving the faintest trace. But Mr. Collins is not baffled so. A pinch of black powder--graphite is commonly used--scattered over the paper, and behold the prints standing out in high relief. A grey powder will act in the same way on a dark surface, and a candle which has been pressed by the fingers may have the print rendered clear by a judicious use of ordinary printer's ink.
