"He went out of the house, closing the street door, O, so quietly behind him. Have you noticed how quietly he does everything? He walks like a cat--well, so can other people. I waited a minute after he closed the street door, and then I slipped out after him. I looked all ways, and I saw him just turning out of the Square into Great King Street. I soon turned the corner too, and there I was walking behind him on the other side of the way, with my eyes glued to him. Well, as good as glued. I can walk a long way behind a person, and never lose sight of him, my eyes are so sharp, and I didn't lose sight of Mr. Richard Manx, as he calls himself. He walked Lambeth way, and I noticed that he was looking about in the funniest manner, as though he was afraid he was being watched. The farther he got from Great Porter Square the more he looked about him; but no one took any notice of him--only me. Well, he went down a street where half the houses were shops and half not, and at the corner of the street was a coffee-shop. There were two doors facing him, one going into the shop where people are served, and the other going into a passage, very narrow and very dark. A little way up this passage was a door, which pushed open. Mr. Manx, after looking about him more than ever, went into the narrow dark passage, and pushed open the door. "What I had to do now was to wait until he came out, and to dodge about so that I shouldn't be seen or caught watching for something I didn't know what. It was a hard job, as hard a job as ever I was at, and it was all that I could do to keep people from watching me. I waited an hour, and another hour, and another hour, and Mr. Manx never came out of the coffee shop. I was regularly puzzled, and tired, and bothered. But I didn't know what a little fool I was till after waiting for at least four hours I found out that the coffee shop had two more doors on the side facing the other street; doors just like the others, one going into the shop, and the other into a narrow dark passage. When I found that out I thought that Mr. Manx must have gone in at one door in one street and come out at the other door in the other street, and I was regularly vexed with myself. But that didn't help me, and I walked away from Lambeth towards Buckingham Palace Road. I wanted to see with my own eyes if Mr. Pelham was at home. He was; I saw him stand for a minute at the window of his room on the front floor. Then I set to watching him. I wanted to find out where he was going to, and what he was up to. I suppose it was seven o'clock, and dark, before he came out. He walked till he met a cab, and as he got in I heard him give the direction of Mrs. Holdfast's house. That was enough for me; I followed him there, my feet ready to drop off, I was that tired. But I wasn't going to give up the job. No one came out of Mrs. Holdfast's house till nine o'clock struck; then the street door was opened, and Mr. Pelham walked into the street.
