Helen Lambie, the other spectator, could give no information about the face (which rather bears out Adams’ view as to her position), and could only say that he wore a round cloth hat, a three-quarter length overcoat of a grey colour, and that he had some peculiarity in his walk. As the distance traversed by the murderer within sight of Lambie could be crossed in four steps, and as these steps were taken under circumstances of peculiar agitation, it is difficult to think that any importance could be attached to this last item in the description.

It is impossible to avoid some comment upon the actions of Helen Lambie during the incidents just narrated, which can only be explained by supposing that from the time she saw Adams waiting outside her door, her whole reasoning faculty had deserted her. First, she explained the great noise heard below: “The ceiling was like to crack,” said Adams, by the fall of a clothes-line and its pulleys of attachment, which could not possibly, one would imagine, have produced any such effect. She then declares that she remained upon the mat, while Adams is convinced that she went right down the hall. On the appearance of the stranger she did not gasp out: “Who are you?” or any other sign of amazement, but allowed Adams to suppose by her silence that the man might be someone who had a right to be there. Finally, instead of rushing at once to see if her mistress was safe, she went into the kitchen, still apparently under the obsession of the pulleys. She informed Adams that they were all right, as if it mattered to any human being; thence she went into the spare bedroom, where she must have seen that robbery had been committed, since an open box lay in the middle of the floor. She gave no alarm however, and it was only when Adams called out: “Where is your mistress?” that she finally went into the room of the murder. It must be admitted that this seems strange conduct, and only explicable, if it can be said to be explicable, by great want of intelligence and grasp of the situation.

On Tuesday, December 22nd, the morning after the murder, the Glasgow police circulated a description of the murderer, founded upon the joint impressions of Adams and of Lambie. It ran thus:

“A man between 25 and 30 years of age, five foot eight or nine inches in height, slim build, dark hair, clean-shaven, dressed in light grey overcoat and dark cloth cap.”

Four days later, however, upon Christmas Day, the police found themselves in a position to give a more detailed description:

“The man wanted is about 28 or 30 years of age, tall and thin, with his face shaved clear of all hair, while a distinctive feature is that his nose is slightly turned to one side. The witness thinks the twist is to the right side. He wore one of the popular tweed hats known as Donegal hats, and a fawn-coloured overcoat which might have been a waterproof, also dark trousers and brown boots.”

The material from which these further points were gathered, came from a young girl of fifteen, in humble life, named Mary Barrowman. According to this new evidence, the witness was passing the scene of the murder shortly after seven o’clock upon the fatal night. She saw a man run hurriedly down the steps, and he passed her under a lamp-post. The incandescent light shone clearly upon him. He ran on, knocking against the witness in his haste, and disappeared round a corner. On hearing later of the murder, she connected this incident with it. Her general recollections of the man were as given in the description, and the grey coat and cloth cap of the first two witnesses were given up in favour of the fawn coat and round Donegal hat of the young girl. Since she had seen no peculiarity in his walk, and they had seen none in his nose, there is really nothing the same in the two descriptions save the “clean-shaven,” the “slim build” and the approximate age.

It was on the evening of Christmas Day that the police came at last upon a definite clue. It was brought to their notice that a German Jew of the assumed name of Oscar Slater had been endeavouring to dispose of the pawn ticket of a crescent diamond brooch of about the same value as the missing one. Also, that in a general way, he bore a resemblance to the published description. Still more hopeful did this clue appear when, upon raiding the lodgings in which this man and his mistress lived, it was found that they had left Glasgow that very night by the nine o’clock train, with tickets (over this point there was some clash of evidence) either for Liverpool or London. Three days later, the Glasgow police learned that the couple had actually sailed upon December 26th upon the Lusitania for New York under the name of Mr. and Mrs. Otto Sando. It must be admitted that in all these proceedings the Glasgow police showed considerable deliberation. The original information had been given at the Central Police Office shortly after six o’clock, and a detective was actually making enquiries at Slater’s flat at seven-thirty, yet no watch was kept upon his movements, and he was allowed to leave between eight and nine, untraced and unquestioned. Even stranger was the Liverpool departure. He was known to have got away in the south-bound train upon the Friday evening. A great liner sails from Liverpool upon the Saturday. One would have imagined that early on the Saturday morning steps would have been taken to block his method of escape. However, as a fact, it was not done, and as it proved it is as well for the cause of justice, since it had the effect that two judicial processes were needed, an American and a Scottish, which enables an interesting comparison to be made between the evidence of the principal witnesses.

Oscar Slater was at once arrested upon arriving at New York, and his seven trunks of baggage were impounded and sealed. On the face of it there was a good case against him, for he had undoubtedly pawned a diamond brooch, and he had subsequently fled under a false name for America. The Glasgow police had reason to think that they had got their man. Two officers, accompanied by the witnesses to identity—Adams, Lambie and Barrowman—set off at once to carry through the extradition proceedings and bring the suspect back to be tried for his offence. In the New York Court they first set eyes upon the prisoner, and each of them, in terms which will be afterwards described, expressed the opinion that he was at any rate exceedingly like the person they had seen in Glasgow. Their actual identification of him was vitiated by the fact that Adams and Barrowman had been shown his photographs before attending the Court, and also that he was led past them, an obvious prisoner, whilst they were waiting in the corridor. Still, however much one may discount the actual identification, it cannot be denied that each witness saw a close resemblance between the man before them and the man whom they had seen in Glasgow. So far at every stage the case against the accused was becoming more menacing. Any doubt as to extradition was speedily set at rest by the prisoner’s announcement that he was prepared, without compulsion, to return to Scotland and to stand his trial. One may well refuse to give him any excessive credit for this surrender, since he may have been persuaded that things were going against him, but still the fact remains (and it was never, so far as I can trace, mentioned at his subsequent trial), that he gave himself up of his own free will to justice. On February 21st Oscar Slater was back in Glasgow once more, and on May 3rd his trial took place at the High Court in Edinburgh.

But already the very bottom of the case had dropped out. The starting link of what had seemed an imposing chain, had suddenly broken. It will be remembered that the original suspicion of Slater was founded upon the fact that he had pawned a crescent diamond brooch. The ticket was found upon him, and the brooch recovered. It was not the one which was missing from the room of the murdered woman, and it had belonged for years to Slater, who had repeatedly pawned it before. This was shown beyond all cavil or dispute. The case of the police might well seem desperate after this, since if Slater were indeed guilty, it would mean that by pure chance they had pursued the right man. The coincidence involved in such a supposition would seem to pass the limits of all probability.
