Hugh had left me, in our stroll, close by the front door which was open, and there I waited until he should have made his circuit. He had hardly disappeared when I heard, quite distinctly, a rather quick but heavy footfall coming along the paved walk towards me from the opposite direction. But there was absolutely no one to be seen who made this sound of rapid walking. Closer and closer to me came the steps of the invisible one, and then with a shudder of horror I felt somebody unseen push by me as I stood on the threshold. That shudder was not merely of the spirit, for the touch of him was that of ice on my hand. I tried to seize this impalpable intruder, but he slipped from me, and next moment I heard his steps on the parquet of the floor inside. Some door within opened and shut, and I heard no more of him. Next moment Hugh came running round the corner of the house from which the sound of steps had approached. “But where is he?” he asked. “He was not twenty yards in front of me--a big, tall fellow.” “I saw nobody,” I said. “I heard his step along the walk, but there was nothing to be seen.” “And then?” asked Hugh. “Whatever it was seemed to brush by me, and go into the house,” said I. There had certainly been no sound of steps on the bare oak stairs, and we searched room after room through the ground floor of the house. The dining-room door and that of the smoking-room were locked, that into the drawing-room was open, and the only other door which could have furnished the impression of an opening and a shutting was that into the kitchen and servants’ quarters. Here again our quest was fruitless; through pantry and scullery and boot-room and servants’ hall we searched, but all was empty and quiet. Finally we came to the kitchen, which too was empty. But by the fire there was set a rocking-chair, and this was oscillating to and fro as if someone, lately sitting there, had just quitted it. There it stood gently rocking, and this seemed to convey the sense of a presence, invisible now, more than even the sight of him who surely had been sitting there could have done. I remember wanting to steady it and stop it, and yet my hand refused to go forth to it.
