November, 1930. One sunny Saturday afternoon, 12-year-old Mena Griffiths was playing in the park when she was lured away by an unknown man. Hours later, her strangled body was found, mouth gagged and hands crossed over her chest, in an abandoned house. Only months later, another girl was murdered; the similarities between the cases undeniable. Crime in Melbourne had taken a shocking new turn: this was the work of a serial killer, a homicidal maniac. Despite their best efforts, police had no experience dealing with this kind of criminal. What followed was years of bungled investigations, falsely accused men - and the tragic deaths of two more girls - before the murderer was finally caught and brought to justice. With all the pace of a thriller, Katherine Kovacic recounts this extraordinary, chilling true story - of failed police enquiries, a killer with a Jekyll and Hyde personality, and the families shattered when four innocent lives were cruelly taken.
