At Leighford High, Peter "Mad Max" Maxwell is temporarily promoted to Head of History when his colleague is chosen for an American exchange. His counterpart is Hector Gold, who is accompanied by his eccentric family including his in-laws, Jeff and Alana O'Malley. Jeff O'Malley has been gate-crashing the local poker school. When Sarah Gregson, one of the poker school's members, is found murdered, newly-promoted Inspector Jacquie Carpenter Maxwell and Henry Hall investigate, with the assistance of Maxwell. As it becomes apparent Sarah suspected Jeff of cheating and Jeff was sacked in LA for being a crooked cop, is this simply a case of murder as revenge for name-calling? Being quite the expert in solving murders, Maxwell believes there is more to it.
