Lynda La Plante (born Lynda Titchmarsh) is a British author, screenwriter, and erstwhile actress (her performances in Rentaghost and other programmes were under her stage name of Lynda Marchal), best known for writing the Prime Suspect television crime series.
A motorway service station on the M1: dimly lit, run down, poorly supervised, flickering lights, dark corners; a favourite stopover for long-distance lorry drivers on their way up north from London. Behind it, a body is found in a ditch, that of a girl barely out of her teens. She appears to have no family, no friends, no connections anywhere. Other girls have gone missing in the vicinity and no one has stepped forward to claim them.
