He came away at last with a quick gesture indicating his discontent, and stood hesitating for a few minutes, when he again started and looked wildly toward the fireplace, for he was convinced that he heard sounds in the next chambers. They ceased, though, directly, and might have come from above; but he once more went back to the panel on the right, listened, and came away dissatisfied still. "I must know," he said with a heavy sigh; and, taking a bunch of keys from his pocket, he stood selecting one which looked black and rusty, a good-sized key, from among those which had been worn smooth and remained bright. This done, he stood hesitating; and, looking straight before him, he shrank slowly backward till checked by a bookcase standing against the wall, when with an angry gesture that he should have been startled by the sight of his own ghastly face in the old mirror, he walked straight to the door on the left of the fireplace. Again he paused for a few moments, and then, with the sweat standing in great beads upon his brow, and the hair at his temples wet and clinging, he slowly, and without a sound, inserted the key, turned it in the well oiled lock, and drew open the door, which came toward him with a faint creak. He stood there peering into the darkness of the narrow, passage-like place, listening, and then came away to the other side of the room, thrust off his boots, and went to the window, which he closed again, and drew down the blind before going back to the door--entering, and walking to the end, to stand listening at the panel in the darkness for some minutes before he came out again, acting now with decision, as he went to the door of exit from the room, and slipped the bolt. Drawing a deep breath, he now hurried across to a little cabinet, from which he drew a bright steel implement, and then, with his brow rugged and his face looking old and worn, he was hurrying across back to the door of the open closet, when he caught his unshod foot in a thick Eastern rug, stumbled forward, and only saved himself from a heavy fall by throwing himself into an easy-chair. He rose, holding his left wrist as if it were sprained, and then stooped to pick up the steel implement he had dropped on the carpet. The change which came over the man was terrible as he stopped there, fixed of eye, fascinated as it were, and unable to move, glaring at a place on the carpet laid bare by the rug being kicked over. And a minute must have elapsed before he could tear himself away and draw himself up to hold the back of his hand across his eyes, as if to shut out some horrible vision. The sigh he heaved was hoarse and strange as he dropped his hand again, and hurriedly drew the rug back into its former position. That done, his mental strength seemed to return, and seizing the steel tool, he listened for a moment, and then hurried into the dark, passage-like closet.
