A gripping murder mystery for adult and teenage readers, set in the early nineteen fifties South Yorkshire . A corpse floats in a swimming pool beneath a dance floor. A blood soaked head is found in a local beauty spot. A woman is clubbed to death and left to rot in medieval tunnels under the city streets. Three brutal murders, ten years apart. What connects them? Why is a senior police officer determined to hide the truth? What really happened under cover of an air raid that killed seventy Christmas revellers in a popular city centre pub? Another Billy Perks investigation. The old team; Billy's pals Yvonne Sparkes and "Kick" Morley with old Etonian, M.D. Doc Hadfield, are joined this time by a new sleuth, rookie cop, P.C. John Needham.
