Uncle Pio acts as Camila Perichole's valet, and, in addition, "her singing-master, her coiffeur, her masseur, her reader, her errand-boy, her banker; rumor added: her father." He was born the bastard son of a Madrid aristocrat and later traveled the world engaged in a wide variety of dubious, though legal, businesses, most related to being a go-between or agent of the powerful, including (briefly) conducting interrogations for the Inquisition. His life "became too complicated" and he fled to Peru. He came to realize that he had just three interests in the world: independence; the constant presence of beautiful women; and the masterpieces of Spanish literature, particularly those of the theater.
