Having had his retirement snatched from him by malfunctioning technology, Peter ‘Mad Max’ Maxwell finds himself facing yet another new year at Leighford High School. His wife Jacquie, her hopes of a dedicated house husband dashed, is further annoyed when a family holiday turns into an impromptu Year Seven school trip. And the situation takes another turn for the worse when someone goes missing, forcing Jacquie to play the role of woman policeman.

As the investigation escalates and a dead body is discovered, Maxwell, researching with paper and pencil, stumbles by accident on the linchpin to the whole case. He knows the reason – all he has to find is the murderer. With the answer lying in a missing piece of paper, divorces and deceit, will Maxwell survive to apply for retirement again?
