he said at last, "the boy was odd, there is no gainsaying the fact. I suppose he was eleven when Clara came down here with her family for Christmas. The Coningtons owned the place then—Mrs. Conington was Clara's sister. It was Christmas Eve, as it is now, many years ago. We had spent a normal Christmas Eve; a little happier, perhaps, than usual by reason of the family reunion and because of the presence of so many children. We had eaten and drank, laughed and played and gone to bed. "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,[Pg 74] and went downstairs.

I crept down very cautiously and waited under the window. First of all, I saw the suit of empty armour 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 armour, 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
