Gary's older brother, Nails, was swimming at the other end of the pool. He could swim like a fish and he and Gary were at the pool every night. But nobody liked Nails. He was hard and dangerous and was always in trouble with the police. The others were afraid of him, the teachers hated him and he had no real friends. Nails and Gary had no mother. She had left home, and they lived with their father, who did not care what they did. But Gary was nicer than Nails and he laughed and smiled sometimes. Nails only laughed if someone had an accident or got hurt. Nutty was watching Nails. He could swim really fast! Perhaps he could help them? But how could you get someone like Nials to help?
