Morse and Lewis investigate the disappearance of teenager Valerie Craven who vanished some six months previously while walking home from her exclusive girls school. Morse is the third detective assigned to the case and is convinced that the girl is by now dead. However, the girl's parents receive a note, purportedly from Valerie. Suspicion falls on a number of people, including fellow students, men named in her diary and some of the teachers at her school. When one of the teachers is killed, the missing persons enquiry becomes a murder investigation. Written by

The setting for this episode was changed from Colin Dexter
's novel of the same name. In the book, the missing girl (called Valerie Taylor rather than Valerie Craven) is a pupil at a seedy council-estate comprehensive school rather than an expensive private girls' school. Her parents live in a small terrace council house rather than an opulent bungalow in its own grounds. These changes were probably made to increase the appeal of the episode to the overseas market.
