K. J. Parker returns to the amoral world of Prosper's Demon with a wry, sardonic novella that flips the eternal, rule-governed battle between men and demons on its head.

An anonymous representative of the Devil, once a high-ranking Duke of Hell and now a committed underachiever, has spent the last forever of an eternity leading a perfectly tedious existence distracting monks from their liturgical devotions. It's interminable, but he prefers it that way, now that he's been officially designated by Downstairs as "fragile." No, he won't elaborate.

All that changes when he finds himself ensnared, along with a sadistic exorcist, in a labyrinthine plot to subvert the very nature of Good and Evil. In such a circumstance, sympathy for the Devil is practically inevitable.
