Mr. Tauchnitz, the second partner, who was intimately acquainted with the working of the business, and had been with Ferguson most of that day, could suggest no reason why the deceased should have gone back to the warehouse. He had never been known to do such a thing before.

As may be imagined, it was a dreadful night for the friends and relatives of the deceased; and the hour being so late when the discovery was made, the police were placed at a tremendous disadvantage. Riga is a large place. It is a populous and busy seaport, doing an enormous trade with other parts of Europe. An immense number of ships of various nationalities were lying in the harbour. As in all maritime places, there was a very rough element always prominent in the town, and after dark many shameful and brutal scenes took place. In addition to the sailors who came and went, there was always a large garrison, for the town is strongly fortified. So what with sailors and soldiers, and the nondescript hangers-on who are always to be found in their wake, law and order were not so well observed as in some other towns; and it will be understood that in the low quarters of such a place a criminal might find safe refuge from pursuing justice. In the instance we are dealing with, all the police could do was to notify the facts to their agents and spies as speedily as possible; but, necessarily, this was the work of hours; and through the long, dreary winter night—for, though nominally spring, the winter still lingered, though the ice had broken up—not much could be done. This, of course, was all in favour of the criminal. He had a big start, and unless he was absolutely a fool he would avail himself of his advantages.

The murder was supposed to have been committed about seven. The discovery was made a little after eight, but it was after nine—in fact, close upon ten—before the police really began to bestir themselves. During the time from half-past six to ten, several trains had left the town, vessels had left the harbour, and vehicles innumerable were driven forth in all directions. It will thus be seen that the murderer had many roads of escape open to him, and it could not be doubted that, if he was really desirous of saving his neck, he would avail himself of the chance he had to get clear.

That the murder was brutal could not be gainsaid; but on the face of it the crime was not one of the ordinary type. Danevitch’s preliminary investigations led him to the conclusion that the motive which had prompted the deed was not robbery. That admitted—and there was evidence of it—the case was invested with a certain mystery suggestive of many things. Tauchnitz and the other partners were questioned by Danevitch as to why Mr. Ferguson had remained behind at the office on that fatal Saturday afternoon, when everybody else had gone. No satisfactory answer could be given to this question. Tauchnitz, who had been with Ferguson all the morning, declared that there was no reason whatever, as far as the business was concerned, why the ill-fated man should have stayed at the office.

‘Was he in the habit of staying?’

‘No.’

‘Was he a methodical man?’

‘Most methodical.’

‘Was he given to making confidants?’

‘No. He was very reticent.’
