Boris was a teacher. He taught science at a high school. For he needed some books for his lessons, he went to a bookshop to buy some. After he put them in his car in a quiet street, he went to buy some other things at other shops. When he came back to his car, one window was open and the books were gone. Boris drove home sadly.
That night he called a newspaper. The next day people read an advertisement in the newspaper:
Books: Have you got any old books? I buy old and modern books. Open all day on Saturdays. Boris 82 West Road.
And then he went to the police station with the Wednesday newspaper at once.
The first weekend, when Boris was staying at home, his first visitor came at 8:30 in the morning. Boris took him to the kitchen. At about ten o’clock another man arrived. He had a bag under his arm.
As soon as he saw Boris, he asked, “Are you Boris?”
“Yes, I am,” Boris said. “What can I do for you?”
“Look! I have got some good books here. You buy books, don’t you?”
“Yes. Bring them in. Let me have a look at them.”
Soon the books were taken in and showed on the dinning-table. “Sir, come out now,” Boris called. “And take the list with you.”
A policeman appeared in the dinning-room. He read the names on the books, and then read the names on the list in his hand. He found that they were the same.
“Come with me, sir,” the policeman said to the man.
