'Well, I had a sort of general idea that there was a building in connection, but my eyes were fixed upon the steps. I seemed to know them. There was a wide open door at top. I felt that I was well acquainted with what was on the other side of that door. On the steps my uncle was standing. Mind, I saw him as well as I see you, and, thank goodness, I can see you pretty well. I can't tell you what he wore, because I'm no hand at describing clothes; but I've an impression that he had on a suit of tweeds and a bowler hat. He was apparently lounging on the steps, watching the passers-by. He did not see me--of that I was sure. On a sudden someone else came towards him up the steps. He was a stranger to me, though I think I should know him if I saw him again. He was taller than my uncle, and, I imagine, younger. Anyhow, he was altogether a bigger and a stronger man. He had a walking stick in his hand, with a horn handle. Directly he got within reach, without, so far as I could judge, uttering a word of warning, with this stick he struck my uncle with all his force across the face. I suspect that my uncle had seen him coming before I did, and, for reasons of his own, had stuck to what he deemed his post of vantage on the steps, being unwilling to go and meet him, and ashamed to run away. That he was not so taken aback by the suddenness of the attack as I was I felt persuaded. He put out his hand to guard himself, and, I fancy, at the last moment was disposed to turn tail and flee. But it was too late. The blow got home. He staggered back and would have fallen had not the stranger gripped him with his left hand, and commenced to belabour him with the stick which he held with his right. People came streaming out of the open door above and up the steps from the street. My uncle made not the faintest attempt at resistance. When the people came close enough to hamper the free action of his arm, the stranger, giving his victim a push, sent him head foremost down the steps. In an instant the whole thing vanished.' Mr Holland ceased. The lady had been regarding him with wide-open grey eyes. 'Guy!' she said. 'Wasn't it odd?' 'Odd? You must have been dreaming.' 'I was as wide awake as you are. It was a mirage, or vision, or something of the kind. The queerest part of it was that it was so amazingly real, and so near. When the thing had gone I kept asking myself why I hadn't jumped up and interfered. I could have got there in a dozen strides.' 'Then what happened?' 'I sat for a long time half dazed, half expecting the thing to come again, or to continue from the point at which it had left off. Then I went and told a man with whom I was chumming what I'd seen. He said the sun had got into my eyes, advised me to have a drink--made fun of it altogether. But I knew better; and, as it turned out, I was haunted by my uncle all through the night.' 'Awake or sleeping?'
