Jane Charlotte has been arrested for murder. During questioning, she tells police that she is a member of a secret organisation devoted to fighting evil. Her division, 'The Department for the Final Disposition of Irredeemable Persons' - or 'Bad Monkeys' for short - is an execution squad that goes around ridding the world of especially evil people. Although the man she has been arrested for killing was not on the official target list.
This confession earns Jane a trip to the jail's psychiatric wing, where a doctor interviews her at length about her career as an assassin. As Jane's tale grows increasingly bizarre - with references to hidden messages in crosswords, dollar bills that can see, and axe-wielding Scary Clowns - the doctor does his best to sort truth from lies, but whenever it seems he's getting to the bottom of things, there's another twist to unravel. Not until the full story is told will we learn whether Jane is lying, crazy - or playing a different game altogether.
