Koeler took special notice of the tall woman who was nicely dressed, but she was wearing ugly, thick-soled(厚底) shoes.
Now the woman was taken to a room for questioning. There it was found that the soles of the shoes were hollow(中空的). They were opened. Some diamonds fell out on the floor. Their total weight was 3377 carats(克拉).
The young woman broke down in tears. Then she told her story. For years she had dreamed of coming to live in America, she said. At last she had managed to get the papers she needed to come to the U.S. Then a strange man called on her. He said he would pay for her trip and give her one hundred dollars. All she had to do was to smuggle the diamonds past the U.S. Customs. The man gave her the shoes and also bought her a plane ticket. Just before she got on the plane, he gave her an envelope. He said that it was the hundred dollars he had promised.
The weeping woman handed the envelope to Koeler. He tore it open. There was only eighteen dollars. She was cheated. In the end the woman was trialed and sentenced to eighteen months in prison for her part in the smuggling.
