On the train ride to Barberton, Peekay meets Hoppie Groenwald, who shows Peekay his boxing gloves. Hoppie is a boxing champion, and he invites Peekay to watch him box during a stop in the ride. It is there that Peekay is inspired to be the welterweight champion of the world. Hoppie teaches Peekay the phrase "First with your head, then with the heart," a phrase which Peekay commits to memory. At Barberton, Peekay sees his mother again. She has returned from the mental institution and converted to being a born again Christian. He learns that his mother had left his nanny because she refused to convert. His mother also tries to convert him, but he tells his mother that the Lord is a "shithead." Retreating to the hills behind his home, Peekay meets a German professor, Karl von Vollensteen, whom Peekay calls "Doc." Doc is a music professor and botanist who collects cacti and has his own cacti garden. Doc and Peekay become close friends, and he offers Peekay piano lessons. When World War II breaks out, Doc is taken into the Barberton prison for being an unregistered alien. Peekay visits him every day for piano lessons, and attends the prison's boxing squad. A prisoner with whom Peekay becomes friends, Geel Piet, teaches him to box, and Peekay leads the team to a victory. Later, Peekay develops great sympathy for the prisoners and arranges Doc and Geel Piet a letter-writing service and a tobacco distribution service. This makes Peekay very famous among the prisoners, and they call him the great chief "Tadpole Angel" (a reference to Doc being the "Frog" for his nightly piano playing). One of the warders discovers that some suspicious activity has been going on, and one night, Geel Piet is murdered in the gym.
