Le Démon de maître Prosper
The French edition (translated by Michel Pagel) of K.J. Parker's Prosper's Demon (2020). An unnamed, morally ambiguous exorcist has built a career on ridding people of demons — his methods are effective, if indelicate, and he rarely worries what becomes of the person afterward. His latest case is Prosper of Schanz, a man of science determined to raise the world's first philosopher-king by the purest principles — and possessed by a demon the exorcist has crossed paths with before. Removing it is simple. Deciding whether he should, when the demon may be exactly what makes Prosper's genius possible, is not. A pitch-dark, witty fantasy novella about demons, broken faith, and worse men.
A polymath scholar and tutor determined to raise the world's first philosopher-king by the purest principles — and, unknown to himself, possessed by a demon the exorcist has crossed paths with before.
