To Oliver’s great surprise, the two boys1 crossed the street and stopped behind an old gentleman. The Dodger put his hand into the man’s pocket, pulled out a handkerchief and gave it to Charley Bates. Then they ran away round the corner.

Now Oliver understood the game which the boys played every morning. He stood for a moment, surprised and frightened, and then he started running too.

Just at that moment the old gentleman put his hand into his pocket. He didn’t find his handkerchief and quickly turned around. When he saw Oliver who was running away, he thought that the boy was the thief. He shouted, “Stop, thief!” and started running after him.

Very soon a lot of people were running after Oliver, and they stopped him at last. A policeman appeared and took the poor boy to the police station.

The old gentleman was sorry for Oliver when he saw how pale and frightened the boy was. “Please, do not punish him too strict,” he said. “I’m afraid the boy is ill”.

“Oh, yes,” said the officer. He laughed and turned to Oliver, “What’s your name?”

Oliver tried to answer, but he was so frightened that he couldn’t speak.

“Don’t you hear? What’s your name?” shouted the officer.

“Take care of him, officer”, said the old gentleman, “he will fall down”.

Oliver couldn’t stand any more and fell down onto the floor. At this moment the door opened and a man ran into the office.

“Stop, stop! Don’t take him away!” cried the man.

“What is this? Who are you? Go away!” cried the officer.

“I will speak ,” cried the man, “I will not go away”. I’m a shop assistant. I saw it all. I saw three boys: two others and the prisoner here. They were standing an the other side of the street when this gentleman was reading. The other boy stole the handker.
