Joe had dodged the police many times, but never like this. He was afraid. He was _1_ on the roof listening for sounds. Somewhere below people were _2_, but he was not concerned about the commotion. He looked round, searching for any sign of a policeman. When he heard some footsteps on the corrugated iron roof, he was seized with fear. What made them chase after me, he thought. I haven't done anything. You shouldn't have _3_ here, he said to himself. Then he saw the shape of a policeman approaching. He did not want to _4_. He still wanted to _5_ to escape. He rose to his feet quietly and _6_ over to the far end of the roof, thinking that he could perhaps slide down the drainpipe. Just at that moment, the policeman strode forward and _7_ the boy by the collar when, _8_a clothesline in his way which caught his cap, he almost stumbled. Joe was startled, but he could go back no further. The policeman _9_ himself and _10_ for the boy.
