In a botched demonic extraction, they say the demon feels it ten times worse than the man. But they don’t die, and we do. Equilibrium. The unnamed and morally questionable narrator is an exorcist with great follow-through and few doubts. His methods aren’t delicate but they’re undeniably effective: he’ll get the demon out—he just doesn’t particularly care what happens to the person. Prosper of Schanz is a man of science, determined to raise the world’s first philosopher-king, reared according to the purest principles. Too bad he’s demonically possessed.

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.
