Jeffrey Dahmer, Ted Bundy, John Wayne Gacy, The Hillside Strangler . . . serial murderers are the most horrific of all criminals. Kate Kray, whose marriage to gangster Ronnie Kray offered her access to a gruesome underworld few would dare to enter, peers into the minds of the worst killers to reveal the awful truth of their abominable acts. The extreme nature of their violence and their shocking lack of remorse makes for uncomfortable yet fascinating reading. From obsessive sexual predators and extreme sadists to cannibals and head hunters, each type of psychopath is examined, their crimes told with grim frankness. Kate's connections allow her to ask uncomfortable questions few would dare to ask such men. Offering extraordinary insight into the motivations of violent perpetrators often portrayed as monsters, this book begs the question of whether such individuals can themselves be viewed as victims of a troubled past, or merely as exponents of pure evil.
