Until that moment I had not heard a sound in the house, and I was not certain that anyone had entered the room even now, until I saw a tiny disk, the end of a ray of light, on the wall. The disk moved, so the man holding the lantern was moving. The next moment he almost trod upon me. His first care was to see that the curtains covered the windows securely, and it evidently never occurred to him that there might be watchers in the room. It was discovery from without that he was afraid of. The ray from his lantern swung about the room for a moment, then he switched on the electric light. As he had drawn the curtain closer across the window, I had arranged the folds so that no scrap of my clothing should show beneath them. Now I made a slit in the fabric with my penknife so that I could watch him through it. He was middle-aged, well groomed, decently dressed. Having glanced round the room, he placed a bag and the lantern on the floor and went to the sideboard. He put a little spirit into one of the tumblers and added a little water--a very modest dose, indeed--and, having just sipped it, he poured some of the contents into two other glasses, and placed the three glasses on a small table near the door, so that no one could fail to see them on entering. Then he broke off a piece of biscuit, crumbled it in his hands, and scattered the crumbs beside the glasses. The cigarette box he did not touch, but he took some cigarette-ends from his pocket and threw them on the floor. These preliminaries seemed stereotyped ones, and he appeared glad to be done with them. There was a curious eagerness in his face as he bent down and opened his bag, taking a thin chisel from it, and from his hip pocket he took a revolver. His method was systematic. He began at one corner of the room, and opened every drawer and box he could find. If a drawer were locked, he pried it open. He laid the revolver ready to his hand upon the piece of furniture he was examining. Every drawer he emptied on to the floor. Some of the contents he hardly looked at. Indeed, most of the contents did not interest him. But now and then his attention was closer, and at intervals he seemed puzzled, standing quite still, his hands raised, a finger touching his head, almost as a low comedian does when he wishes the audience to realize that he is in deep thought. For some time I could not make out what kind of article it was to which he gave special attention, but presently noticed that anything in ivory or bone interested him, especially if it were circular. I remembered the counters in Sir Joseph's room, and wished we had thought to place some in here to see what he would have done with them.
