Casanova continues his reminiscences: his incarceration, his escape and subsequent travels and his duel with Grimani.

Continuing his reminiscences to Edith, Casanova relates the aftermath of his daring prison break from Venice, where Grimani was responsible for his incarceration. Accompanied by his young bastard son and Rocco, Casanova travels through Europe, searching for a sympathetic Venetian ambassador who will grant him a pardon so that he may return to Venice and Henriette. In Paris, he chances on Bellino. In London, he briefly glimpses Henriette herself and later trades insults with Grimani, who challenges him to a duel. In the exchange of pistol shots, he learns that Henriette loathes Grimani. Wounded, Casanova travels to Saxony, where a mysterious nurse (Selina Cadell) sent by an anonymous benefactor saves his life. A visit to Naples on the eve of an eruption of Vesuvius puts him back in touch with Bellino, who introduces Casanova to his previously unknown daughter, now grown up and irresistibly attracted to Casanova's grown up son (Tom Burke). The prospect of incest between brother and sister is too much for our hero, proving that he has standards after all. Years later, he laments to Rose his abiding love for Henriette - concerning whose fate one last message arrives.
