What this book is about

Machado de Assis's 1899 masterpiece is narrated by Bento Santiago, a retired lawyer who tells the story of his marriage to Capitu and his growing conviction that she was unfaithful. The novel is a landmark of unreliable narration — the reader is never given certainty about whether Capitu was innocent or guilty, and the narrator's jealousy and self-deception are the real subject. One of Latin American literature's most psychologically complex novels. Available in English translation.
