Somehow this answer got on my nerves, for the queer feeling which had accompanied that cold current of air had not left me. If anything it had become more acute.

“But surely you know whether you saw anything or not?” I said.

“One can’t always be certain,” said he. “I say that I don’t think I saw anything. But I’m not sure, either, whether the story I am telling you was quite concluded last night. I think there may be a further incident. If you prefer it, I will leave the rest of it, as far as I know it, unfinished till to-morrow morning, and you can go off to bed now.”

His complete calmness and tranquillity reassured me.

“But why should I do that?” I asked.

Again he looked round on the bright walls.

“Well, I think something entered the room just now,” he said, “and it may develop. If you don’t like the notion, you had better go. Of course there’s nothing to be alarmed at; whatever it is, it can’t hurt us. But it is close on the hour when on two successive nights I saw what I have already told you, and an apparition usually occurs at the same time. Why that is so, I cannot say, but certainly it looks as if a spirit that is earth-bound is still subject to certain conventions, the conventions of time for instance. I think that personally I shall see something before long, but most likely you won’t. You’re not such a sufferer as I from these—these delusions——”

I was frightened and knew it, but I was also intensely interested, and some perverse pride wriggled within me at his last words. Why, so I asked myself, shouldn’t I see whatever was to be seen?...

“I don’t want to go in the least,” I said. “I want to hear the rest of your story.”

“Where was I, then? Ah, yes: you were wondering why I didn’t do something after I saw the train move up to the platform, and I said that there was nothing to be done. If you think it over, I fancy you will agree with me.... A couple of days passed, and on the third morning I saw in the paper that there had come fulfilment to my vision. Sir Henry Payle, who had been waiting on the platform of Dover Street Station for the last train to South Kensington, had thrown himself in front of it as it came into the station. The train had been pulled up in a couple of yards, but a wheel had passed over his chest, crushing it in and instantly killing him.
