It's Christmas Eve and DS Bunny McGarry is in the mood to celebrate - he's back on active duty having successfully proven that throwing a senior officer off a building was an appropriate step to take in the course of an investigation. However, his festivities are interrupted when someone attempts to assassinate him while he's trying to take a leak - is nothing sacred? The thing is, the assassin isn't all he initially appears, and Bunny soon finds himself in a race against time to trace a kidnapped child before the people who ordered the hit realise that he is considerably less dead than they had hoped. Bunny is making a list but he's only checking it once because time is of the essence and some people need a refresher in the meaning of Christmas.
