"Wait a minute. I say that because it was too dark for me to know. I merely saw some blackish object on the bench, rising into view above the level of the back of the seat. I couldn't say it was man, woman or child. But something there was, and I found that I was looking at it."

"I understand."

"Gradually, I also found that my thoughts were becoming fixed upon this thing or person. I began to wonder, first, what it was doing there; next, what it was thinking; lastly, what it was like."

"Some poor creature without a home, I suppose," said the Father.

"I said that to myself. Still, I was taken with an extraordinary interest about this object, so great an interest that I got my hat and crossed the road to go into the Park. As you know, there's an entrance almost opposite to my house. Well, Murchison, I crossed the road, passed through the gate in the railings, went up to the seat, and found that there was—nothing on it."

"Were you looking at it as you walked?"

"Part of the time. But I removed my eyes from it just as I passed through the gate, because there was a row going on a little way off, and I turned for an instant in that direction. When I saw that the seat was vacant I was seized by a most absurd sensation of disappointment, almost of anger. I stopped and looked about me to see if anything was moving away, but I could see nothing. It was a cold night and misty, and there were few people about. Feeling, as I say, foolishly and unnaturally disappointed, I retraced my steps to this house. When I got here I discovered that during my short absence I had left the hall door open—half open."

"Rather imprudent in London."

"Yes. I had no idea, of course, that I had done so, till I got back. However, I was only away three minutes or so."

"Yes."
