Lonely Hearts by John Harvey

Shirley Peters is dead. Murdered. And her rejected boyfriend is the obvious prime suspect. But then another woman is murdered and suddenly there appears to be too many connections between these seemingly unrelated crimes. Detective Inspector Resnick is sure that the two murders are the work of one sadistic killer - two lonely hearts broken by one maniac. And it’s up to Resnick to put the record straight - and put the killer where he belongs.
