Part of Honore de Balzac's sprawling epic The Human Comedy, the novella The Commission in Lunacy focuses on the story of a bachelor who feels his youth rapidly slipping away and tries to renew his sense of vigor and fulfillment through various means. He crosses paths with the beguiling Madame d'Espard and soon finds himself caught up in a nefarious scheme.
