This arresting hardback guide brings together shocking case histories of the world's most horrifying killers and their egregious crimes, illustrated throughout with chilling full-color photographs.

Serial killers lead double lives. To those that know them best, they may seem normal, or even charming, yet beneath their pleasant exterior lurks a dark secret. When left to their own devices, they commit some of the most atrocious deeds imaginable, taking pleasure in the pain of their victims and rejoicing in their ability to killing sprees. Killer Psychopaths examines the lives, crimes, and motivations of these terrifying individuals.

This terrifying volume features the gory deeds of such infamous criminals as: - Robert Pickton, the farmer who left the remains of his victims for his pigs to eat, - Harold Shipman, the quintessential Angel of Death who murdered more than 200 people over the course of his medical career, - Paul Knowles, who killed, raped and stole with abandon across the country, - Katherine Knight, who butchered, skinned and beheaded her husband before serving his corpse for dinner, - and Jack Unterweger, the celebrated journalist who covered his own murders for his day job.

Fully illustrated with maps, photographs, illustrations, and information boxes with key facts on the killers and their crimes, this chilling book is the essential guide to those who decide to kill and kill again.
