переведите плиз на русс яз I ran back and told Neesha about the head and her boyfriend and the playing field. This is terrible she said. We must tell the police. Yes I said. But we haven't got any proof. The police are going to believe the head. I've got an idea, said Neesha. My dad's got a really small tape recorder.He uses it for work. We can record what the head says. The head lived near Neesha, in a quiet road, near the park. That evening we went to her house. I walked up to the front door and Neesha waited by the garden wall. The head wasn't at home , but her horrible boyfriend was there. I was just talking to your cat about you, and now here you are,he said when he saw me. And there,in the dining room ,was Maggie. I ran towards her . The boyfriend followed me and then he locked the door behind us. You can't lock me in here I said.My friends are waitimg for me. I spoke loudly so that the tape recorder got every word. You can go home soon ,he said.But first Miss Kay wants to talk to you. You took my cat , I said. Maggie mewed. She looked hungry. Yes he replied. And you put the exam paper in Mr Roberts' desk, I told him. I didn't he said. Your head teacher dif that. He laughet. He had a horrible laugh.
