A teenage girl is found wandering the outskirts of Oxford. She tells a terrifying story. Grabbed off the street, a plastic bag pulled over her face, then driven to an isolated location where she was subjected to what sounds like an assault. Yet she refuses to press charges. DI Fawley investigates, but he can do little without the girl's co-operation. Is she hiding something, and if so, what? One of the most disturbing cases DI Fawley has ever worked.
