1. The Mermaids Singing (Part 1)

Clinical psychologist Dr Tony Hill is asked to help police track down the brutal killer of three men in Bradfield. DI Carol Jordan hopes his skill as a profiler will crack the case, but Tony's off-beat methods cause others to dismiss him. When a cop is killed, the pressure for results mounts. Police focus on the gay scene, while Tony thinks the killer is sending a message on the body of his victim. Then the investigation takes a more personal turn.
