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.
When her boss DCI James Langton is horrifically injured, DI Anna Travis plays a major role in his rehabilitation. Langton was working to solve the murder of a young prostitute, the suspect an illegal immigrant. Anna is working on another murder case and gains enough evidence to send the killer down for twelve years. Two separate cases... which become unexpectedly linked.
