精雕机刀头长度:求英语译文

I left my friend’s house shortly after seven. It was still too early for dinner, so I walked along the seafront for about an hour until I began to feel hungry. Then I went into a favorite restaurant, where I often went.
It was already crowded, and I ordered my dinner. While I was waiting for the soup to arrive, I looked around. It was then that I noticed that a man sitting at a corner table near the door kept glancing in my direction, as if he knew me. I certainly did not know him, for I never forgot a face. The man had a newspaper open in front of him, which he was pretending to read, though all the while I could see that he was keeping an eye on me. When the waiter brought my soup , the man was clearly puzzled by the familiar way in which the waiter and I addressed each other. He became even more puzzled as time went on and it grew more and more clear that I was well, known there. Then he got up and went into the kitchen. Soon he came out, paid his bill and left without another glance at me.
When I had finished and was about to leave, I called the owner of the restaurant over and asked him what the man had wanted. The owner was a little embarrassed by my question and did not want to tell me. I insisted. “Well,” he said,” he was a detective.” “Really?” I said, considerably surprised. “He was certainly very interested in me. But why?” “He followed you here because he thought you were a man he was looking for,” the owner of the restaurant said. “When he came into the kitchen, he showed me a photograph pf the wanted man. He certainly looked like you! Of course, since we know you here, I was able to convince him that he had made a mistake.” “It’s lucky I came to a restaurant where I am known,” I said, “otherwise I might have been arrested!”
