DCI Shefford dies suddenly whilst investigating a murder case. Jane Tennison is given the opportunity to take over the investigation which involves the brutal murder of a young girl. The girl's body has been badly mutilated and her hands have been tied behind her back. Jane suspects that it is the work of George Marlow. Jane also has to win the respect and approval of her male colleagues.

The body of a teenage girl is found and the investigation leads Jane into a community who distrust the police. Jane has recently had an affair with DS Bob Oswalde and he is assigned to the case. David Harvey confesses to the murder but neither Jane or Bob believe him. Bob is convinced that it is really the girl's young neighbour Tony Allen. Together they are able to discover who the real murderer is.
