DI Friend and the team investigate the murder of a young boy who is found in collected refuse. The autopsy reveals that the boy had his heart cut out. Although no children have been reported missing, they manage to trace the victims parents who are from West Africa and have sought sanctuary in a church to avoid deportation. They thought their children were in the care of a nanny selected by their pastor, but it seems they had run away. The focus of the investigation quickly shifts to finding the victims younger brother.

The team investigates two inter-related deaths. In the first a teacher, Martin Ramsay, either jumped or was pushed out of the upstairs window of his house. In the second, a tramp is found floating in the river with his head bashed in. From the evidence and the time line, it appears that the tramp may have come across Ramsay's body, helping himself to his shoes and his wallet, but it is unlikely he had anything to do with his death. Suspects in Ramsey's death include his wife, who was divorcing him; a fellow teacher, Kirsten Hughes who was ending her relationship with him; and Raoul Jimenez who had been harassing him for some time. As the investigation progresses however, the police discover a completely different motive arising from activities at his school.

The MIT investigates the murder of Penny Wake who is found by the river. Forensic evidence shows that the woman was strangled and had been dead for several days and that the body had been moved. The killer also went to great lengths to clean the body before disposing of it. They immediately focus on the woman's husband Neil Wake, who says he has been away from home for a week or so on business but it turns out, was actually on leave having spent a few days with his girlfriend. The investigation takes a different turn when a second abduction victim, Kathy Monroe, is found wandering the streets in her underwear. The key however is that both women had red hair.

The puzzle becomes a mystery when they are unable to locate Morton's victims or any probation records for him.

The case comes full circle when they learn another police officer may be involved.
