Take a terrifying trip into the depths of madness. What is it that turns seemingly ordinary men and women into sadistic, twisted, multiple murderers? Many of the world s most famous serial killers lived apparently normal lives, from the outside appearing to be just like everyone else, but with an insatiable appetite for evil lurking within. This fascinating collection investigates what drives these people to murder, the extent to which the law will go to stop them, and the depths to which human beings can stoop to satisfy their most depraved urges. Includes an in-depth exploration of women who kill, as well as a close look at what actually constitutes a psychopath, looking specifically at cold-blooded killers such as Ted Bundy and John Wayne Gacy. Features detailed case histories of serial killers from around the world, including Marc Dutroux (Belgium), Ivan Milat (Australia) and Dennis Rader (USA). Contains a special programme on The Monster of Florence , a brutally violent serial murderer who to this day has never been apprehended.
