Ragged and barefoot, 26-year old Ivy Moxam is found wandering the streets of Bristol, 13 years after she disappeared and is interviewed by detectives Lisa Merchant and Elliot Carne before being reunited with her parents, Christina and her estranged husband Angus, who find themselves besieged by the press, as does her old headmaster Henry Stone. Ivy claims she had skipped school to meet her friend Eloise and was abducted by a man she knew as Leonard, who imprisoned her in a cellar though the house in question is empty and the police believe Leonard was a false name for a man who worked at Ivy's school. Her boyfriend Tim is over-joyed to see her but her sister Emma is not convinced that this really is Ivy.
