6、Tom Smith was a writer. He wrote detective stories _ _ 21 _ _ magazines. One evening he could not find an end for a story. He sat _ _ 22 _ _ his typewriter in front of him; but he had no ideas. So he decided to go to the cinema.
When he came back, he saw that he had had a visitor. Someone had broken into his flat. The man had had a drink, smoked several of Tom's cigarettes and had read his story. The visitor left Tom a note:
I _ _ 23 _ _ your story and I don't think much of it. Please read my suggestions and then you can finish it. By the way, I am a thief. I am not going to steal _ _ 24 _ _ tonight. But if you become a successful writer, I will be back!
Tom read his suggestions. Then he sat _ _ 25 _ _ and wrote the rest of the story. He is still not a successful writer, and he is waiting for his thief to return. Before he goes out in the evening, he always leaves a half - finished story near his typewriter.
