"I woke in the middle of the night from sheer restlessness. Clara, knowing my weakness, had given me a fire in my room. I lit a cigarette, played with a book, and then, purely from curiosity, opened the door and looked down the passage. From my door I could see the head of the staircase in the distance; the opposite wing of the house, or the passage rather beyond the stairs, was in darkness. The reason I saw the staircase at all was that the window you pass coming downstairs allowed the moon to throw an uncertain light upon it, a weird light because of the stained glass. I was arrested by the curious effect of this patch of light in so much darkness when suddenly someone came into it, turned, and went downstairs. It was just like a scene in a theater; something was about to happen that I was going to miss. I ran as I was, barefooted, to the head of the stairs and looked over the banister. I was excited, strung up, too strung up to feel the fright that I knew must be with me. I remember the sensation perfectly. I knew that I was afraid, yet I did not feel fright.
"On the stairs nothing moved. The little hall down here was lost in darkness. Looking over the banister I was facing the stained glass window. You know how the stairs run around three sides of the hall; well, it occurred to me that if I went halfway down and stood under the window I should be able to keep the top of the stairs in sight and see anything that might happen in the hall. I crept down very cautiously and waited under the window. First of all, I saw the suit of empty armor just outside the door here. You know how a thing like that, if you stare at it in a poor light, appears to move; well, it moved sure enough, and the illusion was enhanced by clouds being blown across the moon. By the fire like this one can talk of these things rationally, but in the dead of night it is a different matter, so I went down a few steps to make sure of that armor, when suddenly something passed me on the stairs. I did not hear it, I did not see it, I sensed it in no way, I just knew that something had passed me on its way upstairs. I realized that my retreat was cut off, and with the knowledge fear came upon me.
"I had seen someone come down the stairs; that, at any rate, was definite; now I wanted to see him again. Any ghost is bad enough, but a ghost that one can see is better than one that one can't. I managed to get past the suit of armor, but then I had to feel my way to these double doors here."
