The novel is a sprawling tale of deception, magic, and family history, narrated by a 139-year-old Australian con artist. He recounts his life's adventures, from snake handling to aircraft manufacturing, while weaving in the stories of his descendants. The narrative is a blend of historical fiction and tall tales, exploring themes of national identity, truth, and the art of storytelling itself. Through the protagonist's unreliable narration, the book challenges the reader to discern fact from fiction, all while painting a vivid picture of Australian society and its transformation over the 20th century.

The book is a fictionalized account of the life of Fray Servando Teresa de Mier, a real-life Dominican friar from the 18th century. It follows his numerous escapes from colonial authorities across Latin America and Spain after he delivered a controversial sermon in Mexico City. The narrative, infused with magical realism, portrays Fray Servando's adventures and misfortunes as he becomes a symbol of freedom and resistance against oppressive regimes. His journey is marked by a series of bizarre and fantastical encounters, reflecting the author's critique of totalitarianism and exploration of the themes of liberty, identity, and the absurdity of political persecution.
