On an internationally acknowledged 'Scale of Evil', these are the world's worst serial killers. The qualifications for entry to this list of the vilest criminals of all times are a propensity for sadism, torture and murder without a shred of remorse. Using expert evidence, this book looks behind the headlines and delves into the minds of monsters. What drove them to crime? What turned seemingly ordinary members of society into sick slayers? How did they self justify their heinous deeds? And, quite simply, how did they get away with murder? Included in this catalogue of the world's most evil killers are men who committed crimes so monstrous that they almost defy belief – yet to their neighbours and work colleagues seemed quite normal. Dennis Radar was a respected pillar of society yet set out on nightly killing sprees. David Parker Ray was just an 'average working guy' but had a torture chamber in his backyard. Fred and Rose West raised a large extended family yet violently abused and murdered their own children. These are examples of the killers who sank to the darkest depths of depravity. Find out what made them such monsters in 'Serial Killers: The World's Most Evil'. AUTHOR: Nigel Blundell is a journalist who has worked in Australia, the United States and Britain.
