Juve went up the five floors to the flat formerly occupied by Gurn, reflecting somewhat moodily. Of course Gurn's arrest was a success, and it was satisfactory to have the scoundrel under lock and key, but in point of fact Juve had learned nothing new in consequence of the arrest, and he was obsessed with the idea that this murder of Lord Beltham was an altogether exceptional crime. He did not yet know why Gurn had killed Lord Beltham, and he did not even know exactly who Gurn himself was; all he could declare was that the murder had been planned and carried out with marvellous audacity and skill, and that was not enough.
Juve let himself into the flat and closed the door carefully behind him. The rooms were in disorder, the result of the searches effected by the police. The rent had not been paid for some time, and as no friend or relation had come forward to assume control of Gurn's interests, the furniture and ornaments of the little flat were to be sold by auction.
The detective walked through the rooms, then flung himself into an arm-chair. He did not know precisely why he had come. He had searched the place a dozen times already since his discovery of the corpse within the trunk, and had found nothing more, no tell-tale marks or fresh detail, to assist in the elucidation of the mystery. He would have given very much to be able to identify Gurn with some other of the many criminals who had passed through his hands, and still more to be able to identify him with that one most mysterious criminal whose fearful deeds had shocked the world so greatly. Somehow the particular way in which this murder was committed, the very audacity of it, led him to think, to "sense," almost to swear that——
Juve got up. It was little in accord with his active temperament to sit still. Once more he went all round the flat.
"The kitchen? Let me see: I have been through everything? The stove? The cupboards? The saucepans? Why, I went so far as to make sure that there was no poison in them, though it seemed a wild idea. The anteroom? Nothing there: the umbrella stand was empty, and the one interesting thing I did see, the torn curtain, has been described and photographed officially." He went back into the dining-room. "I've searched all the furniture: and I went through all the parcels Gurn had done up before he left, and would, no doubt, have come back for at his leisure, had it not been for my discovery of the body, and the unfortunate publicity the newspapers gave to that fact." In one corner of the room was a heap of old newspapers, crumpled and torn, and thrown down in disorder. Juve kicked them aside. "I've looked through all that, even read the agony columns, but there was nothing there." He went into the bedroom and contemplated the bed, that the concierge had stripped, the chairs set one on top of another in a corner, and the wardrobe that stood empty, its former contents scattered on the floor by the police during their search. There, too, nothing was to be found.
Against the wall, near the fireplace, was a little escritoire with a cupboard above it, containing a few battered books.
"My men have been all through that," Juve muttered; "it's most unlikely that they missed anything, but perhaps I had better see."
He sat down before it and began methodically to sort the scattered papers; with quick, trained glance he scanned each document, putting one after another aside with a grimace expressive of disappointment. Almost the last document he picked up was a long sheet of parchment, and as he unfolded it an exclamation escaped his lips. It was an official notice of Gurn's promotion to the rank of sergeant when fighting under Lord Beltham in the South African War. Juve read it through—he knew English well—and laid it down with a gesture of discouragement.
"It is extraordinary," he muttered. "That seems to be perfectly authentic; it is authentic, and it proves that this fellow was a decent fellow and a brave soldier once; that is a fine record of service." He drummed his fingers on the desk and spoke aloud. "Is Gurn really Gurn, then, and have I been mistaken from start to finish in the little romance I have been weaving round him? How am I to find the key to the mystery? How am I to prove the truth of what I feel to be so very close to me, but which eludes me every time, just as I seem to be about to grasp it?"
He went on with his search, and then, looking at the bookcase, took the volumes out and, holding each by its two covers, shook it to make sure that no papers were hidden among the leaves. But all in vain. He did the same with a large railway time-table and several shipping calendars.
