Martyn attempts to seduce Tim into becoming his servant using a succubus called Leah, using magic to make Tim's father spontaneously combust so that the boy is alone and vulnerable. Tim is saved once from Leah by the arrival of Molly, as the succubus is touched by the genuine love between the two... but in his grief and anger, Tim manages to push Molly away and cause Leah to think he is "just like all other men" and needs punishing. Tim's salvation from Martyn comes in an unlikely form when Sir Timothy and Barbatos kill the magician to protect their own interests in the boy. This leaves Leah without a master, a position that she attempts to make Tim fill before the young magician proves his worth by setting her free. She leaves England to see where her new freedom - and Martyn's car - will take her.
