The illegitimate birth of twin boys in 1945: the infamous Bible John slayings: two present day murders. What is the terrifying link that connects all three? During the late 1960's, the actions of a vicious serial killer prophetically dubbed 'Bible John' caused mass hysteria among the young women of Glasgow, holding them in a chilling, vice-like grip of terror. Then, inexplicably, in late 1969, almost as quickly as they had begun, the killings stopped. It is 2010 and two teenage girls are dead, strangled. On the surface the authorities appear to treat the murders as unrelated but ambitious young policeman, DCI Mason Blackwell, has other ideas...and a vested interest. A personal link to the original murders compels him to delve deeply to try and establish a connection between generations. Blackwell, his good friend and colleague, DI Theresa Bremner, and ex-Special Forces agent, Tom Logan, now a top criminal psychologist, join forces to form a special unit designed to track down the killer. In an age of recession and budget cuts, an already depleted police force is then stretched almost to breaking point by the emergence of another killer - one who randomly executes wife beaters and child abusers. The scene is set for a nightmarish journey for Mason Blackwell and his team as the crime count threatens to spiral out of control. Expect the unexpected as the story dramatically twists and turns, sending all concerned towards a violent and terrifying conclusion...
