John Smith was a writer, who wrote detective stories for magazines, though he never dealt with criminals（罪犯）. One evening he could not finish an end for a story. He sat in his study（书房）, but he had no ideas. So he decided to go to the cinema.

When he came back, he found that he had had a visitor. Someone had broken into his house. The visitor had had a drink, smoked several of his cigarettes and had read his story. The visitor left him a note.

“I have read your story and I don’t think it is very good. Please read my suggestions and you can finish it. By the way, I am a thief. I’m not going to steal anything tonight. But if you become a successful writer, I will return.”
