When he was a child, Liam Granger never thought of being a serial killer. He overcame a series of setbacks in life, including the death of his parents, and managed to put everything behind him as he grew into a mid-twenties man. However, one final act re-ignited his suppressed emotions and pushed Liam over the edge of reason and into the abyss of revenge. So the killings began, regularly one every month. Along the way, Liam picked up the 'name' JASON. Detective Graham Tonnick was used to winning, but the JASON murders presented a new challenge - his team were struggling to crack them. His team were being made to look stupid and his frustration increased with the steadily rising body count. Then the murders abruptly stopped, only starting again six months later with the next victim particularly close to the detectives. Just over a year after it started, the team believed the tables had turned and they were finally closing in, but were they, or would Liam once again give them the slip?
