The Mermaids Singing (1)

Gruesome murders with an apparent sexual bent strike fear into a community. Instruments of torture are being used - and the victims are getting closer to home. Two men have been found mutilated and tortured. Fear grips a city, no man feels safe. Detective Inspector Carol Jordan seeks out Dr Tony Hill to help police track down the brutal killer in the Northern town of Bradfield. Carol hopes his skill as a profiler will crack the case, but Tony's off-beat methods cause others to dismiss him.

Until now, the only serial killers Tony has encountered are safely behind bars. He's a clinical psychologist, who has devoted his career to helping jailed killers find peace, and in so doing, find the final facts that can help the victim's families find closure. But this case is different - this killer's on the loose. Carol Jordan is desperate for his help to persuade her colleagues that the killings part of a serial pattern, not three isolated killings.

The rest of Bradfield police force are less convinced by Tony because as far as they're concerned, he can't tell them anything they don't already know. But when there's another murder things change - this time the victim is a cop, who has suffered the most unspeakable torture at somebody's hands...
