Sam woke up suddenly. Someone was moving around in the next room. “Maybe it’s his grandmother, getting a glass of water,” he told himself. But the next room was the living room. It wasn’t near the kitchen. Sam’s parents were away, and there was only his grandmother in the house with him. He looked at his watch. It was three thirty! Too early for his grandmother to get up!

He got out of bed and opened the door very quietly. The window was open. A man was standing near it and looking in the dark drawers. His grandmother kept her money there! He thought quickly. Yes, the radio! He turned it on and a man’s voice filled the room. The thief felt scared and jumped onto the window. Then he jumped down two floors to the ground. He gave a shout.

His grandmother was awake and she called the police right away. The thief couldn’t get up, because his leg was badly hurt. When the policemen came, they were very happy. “Great, Sam,” said a policeman. “This man is a famous thief.”
