Part the Second deals with D'Elmont's falling in "true" love with Melliora, a girl entrusted in his care. At the first sight of "the matchless Melliora", his "impregnable" heart "surrendered". Alovisa, angered by her husband's increasing distance, tries to discover his lover. The Baron D'Espernay, a close friend of D'Elmont, helps him plot to seduce Melliora—in part because he desires Alovisa for himself. D'Espernay plans a ball, during which D'Elmont is arranged to have access to Melliora, but Melantha, D'Espernay's sister, is enamored with D'Elmont and takes Melliora's room. When D'Elmont enters what he thinks is Melliora's chamber, he instead ravishes the too-willing Melantha. D'Espernay is disgusted by his sister's amorousness, even though he is not innocent, either. Alovisa, certain that D'Espernay can help her discover the identity of her husband's lover, agrees to trade sexual favors for this knowledge and asks Chevalier Brillian to save her at just the right moment. In the chaos of the evening, Alovisa ends up running into D'Elmont's sword. D'Elmont ends up nearly raping the loving but resisting Melliora; meanwhile, D'Elmont's friend, Baron D'Espernay, falls in love with D'Elmont's wife Alovisa. A climax scene leads to the death of the Baron and Alovisa and D'Elmont's self-exile.
