Fifteen-year-old Cassie Booth goes missing on her paper round. Then her bloodstained jacket is found in a boathouse belonging to Karl Wilding - but there's little evidence against him.

A routine visit by Detective Inspector Pat North to appease persistent complainer Stephen Warrington spirals into something far more sinister. As his behaviour becomes increasingly obsessive, North is caught in a frightening web of deceit and lies that fuels her suspicion that Warrington has been involved in a far more horrific crime.

Only one of the men is guilty of murder. Can the jury unravel the complex web of lies and find justice for Cassie?
