The mermaids singing

Up till now, the only serial killers Tony Hill had encountered were safely behind bars. This one's different -- this one's on the loose. In the northern town of Bradfield four men have been found mutilated and tortured. Fear grips the city; no man feels safe. Clinical psychologist Tony Hill is brought in to profile the killer. A man with more than enough sexual problems of his own, Tony himself becomes the unsuspecting target in a battle of wits and wills where he has to use every ounce of his professional nerve to survive.
