French teacher at Rowhurst, and Frederique's father. When the boys try to escape, he leads the infected teachers to attack them, and captures one of them. Jack kills him by hitting him with a plank of wood with nails sticking out, driving the nails into his skull. Frederique is never told exactly what happened to him, but she is told that he is dead. Mr. Hewitt – An English teacher at Rowhurst. He tries to help the boys in the early stages of the outbreak, until he came down with the sickness (before the beginning of the book). In the beginning, he tries to eat Jack and Ed, but slices open his stomach crawling through a window, and they escape. The boys later find his head (the adults ate his body) while escaping the school, and throw it in a trash can. Mr. Langston – An elderly history teacher at Rowhurst. He pursues the boys and Frederique to the church. As he tries to get the gate open, Jack hits his head with a piece of rebar, and kills him shortly after. Ms. Warlock – An English teacher at Rowhurst. She pursues the boys and Frederique when they go to the church. She remains outside while Mr. Langston tries to open the gate. Bam leaps over the wall and knocks her over, and kills her immediately afterward. Pez – A young infected man whose cheeks have been slashed through, causing his lower jaw to hang down and rendering him unable to bite, also making him look like a living pez dispenser. He first appears with a group of adults attacking the coach after Greg turns on the children. After the kids (sans Piers) escape, he appears among the sickos attacking the scavenging group at Tesco. After they escape again, he is among the adults attacking the kids trying to cross Lambeth Bridge. He attempts to bite Ed, but cannot due to his injuries, and Kyle kills him. He has dark hair and yellow eyes. Other characters Dior - Frederique's cat, who she carries with her in the early stages of the book. It was a gift to her father, the French teacher at Rowhurst, and she feels obligated to care for it, to the point where she nearly causes sickos to attack the group by refusing to abandon it. She later releases Dior after they reach the Imperial War museum,
