Detective Inspector, Mick Chandra of New Scotland Yard, struggles to link the murder of the young wife of a popular British Member of Parliament to the seemingly random death by drowning in a north London canal of 8-year-old Josie Stephens. The forensic pathologist discovers that Josie was abused before she was murdered. Mick is informed by a Quaker Friend who knew Phoebe that she, too, may have been physically abused. Mick realizes he is getting close to the fire when his live-in love, American expatriate and renowned England-based concert pianist, Jessica Beaumont, is suddenly harrassed. During a concert, someone even takes a shot at her. Seconded to the Yard's Pedophile Unit, Mick and his partner, Sergeant Elizabeth Chang, receive help in breaking the case. The Unit's chief informs Mick that a notorious pedophile ring is working out of north London, headed by someone who calls himself The Erlking. Day by day, more children are reported missing in north London. How is this linked to Phoebe's death? What is the connection between Phoebe and Josie? As Mick struggles to expose the identity of The Erlking, help arrives from a most unexpected source.
