If the windows were open at night, when everything was dark and quiet, he could hear many dilferent sounds from the river. One dark night Ron couldn't sleep and he couldn't understand why, He heard noises but they were not usual, He woke up his two brothers, Sid and Alan, because he was afraid. "What has happened?" asked Sid. "It's night and everybody is in bed." "Look over there," said Ron. The boys came to the windows. "Look at the honse near the church, " said Ron. The boys looked at the lhouse and couldn't believe their eyes. There was light in it. "Oh, dear" sald Sid. "Nobody has lived in this house for a long time!" "I have never seen anyone there either," said Alan "Who could it be?" asked Sid, "There is a burglar there!" said Ron. Suddenly the house became dark. "Watch the doors!" said Sid. A man came out the back door. "Look! Here he is. He must be a burglar or maybe a spy!" said Alan. The man came to the traffic lights, turned left and then the boys couldn't see him any more. "We can't catch him now," said Ron."Let's go to the house Omortow. The next day the boys went to the house. Both the front door and he back door were locked. Everything seemed all right. They ouldn't hear a thing. They looked through the window. There was no- dy in The boys watched the house for some time and then went home.

But I want to finish some things in the house and build some things in the garden, so I come here after work." "That sounds great," said the boys. "We hope we'll see a lnt of you. Well, goodbye." "I'm sure you wilf. Goodbye, boys," said Mr Collins and he shut the door. The children started laughing as they waiked back to their house. "A burglarf" said Ron. "A spy!" smiled Sid.
