Fever Of The Bone 

In the sixth novel to feature Tony Hill and Carol Jordan, Tony meets his most twisted adversary to date-a killer with a shopping list of victims, who is unmoved by youth and innocence and driven by the most perverted of desires. The murder and mutilation of teenager Jennifer Maidment is horrific enough on its own. But it’s not long before Tony realizes it’s just the start of a brutal and ruthless campaign targeting an apparently unconnected group of young people.
