Beware Book shines the light on a spate of vicious murders which shocked Glasgow between 1991 and 2005. Eight women involved in prostitution were killed, and at least four of those cases remain unsolved to this day. Many of these women were left defenceless in a more ruthless city than the one we know today - one grappling with unemployment, crime and the growing grip of heroin. Distrustful of authorities and fearing for their safety, they turned to each other for protection, sharing warnings about their most dangerous clients in a tattered leather journal they called the “Beware Book”. This series features deeply personal interviews with the victims’ families — many speaking publicly and at length for the first time. Also a brand-new interview with a former investigating officer about where he thinks the Beware Book is now. While Emma Caldwell’s murder was recently solved, and a man – Iain Packer – jailed, it took 19 years for justice to be served. Hear from some of his other victims and officers who worked on Emma's case - who think there will have been more attacks. Perhaps even another murder. Can we, two Glasgow-based journalists, finally get the answers these families deserve?
