In 1966 the Moors Murderers - Ian Brady and Myra Hindley - were convicted for kidnapping and murdering three children before they were caught and sentenced to life in prison. The case shook the nation and has held us both horrified and fascinated for fifty years. But with new exclusive access to Ian Brady's unpublished autobiography, and to police case files, missing for decades and rediscovered in a loft in Manchester, Staff is now able to detail how at the time of their conviction for the killings of Lesley Ann Downey, 10, John Kilbride, 14, and Edward Evans, 17, the police knew there were in fact five victims. And yet the families of Keith Bennett, 12, and Pauline Reade, 16, were left in the agony of unresolved grief. In this updated edition of his seminal best seller Duncan Staff reveals the injustice caused by a police failure to act on this knowledge and investigate all of the Moors murders - failure that has left families without children to bury, the Moors murderers in control of the narrative, and hideous killings unresolved more than half a century later. He is further able to confirm the truth of his original thesis: that Ian Brady and Myra Hindley had a system - one decoded by officers at the time - by which they recorded where all their victims were buried. Published alongside a BBC documentary series produced by Staff, this is a call to action on behalf of the families of the victims, the people of Manchester and every person who has lived with this case. It is a book that demonstrates exactly why the police should act on all the evidence when presented with serial crimes.
