Don Casmurro by Machado de Assis

A first-person, introspective memoir in which an older man recounts his childhood and life in Rio de Janeiro, his long love for a clever and enigmatic woman named Capitu, and the friendship with a schoolmate who becomes central to his growing jealousy; the narrative slowly unspools episodes of youth, marriage, social expectation and a possible betrayal, while the narrator’s uneasy memory and obsessive doubts leave the question of infidelity unresolved and turn the book into a study of suspicion, the unreliability of memory, and the moral complexities of love and honor.
