Meet Tony Hill's most twisted adversary - a killer with a shopping list of victims, a killer unmoved by youth and innocence, a killer driven by the most perverted desires ...

When teenager Jennifer Maidment's murdered and mutilated body is discovered, it is clear that there is a dangerous psychopath on the loose. But it's not long before Tony and DCI Carol Jordan realise it's just the start of a brutal and ruthless campaign targeting an apparently unconnected group of young people. Their chameleon-like killer is chatting with them online, pretending to share their interests and beliefs - and then luring them to their deaths.
