"Dom Casmurro" by Machado de Assis is a novel published in 1900. Bento Santiago, a wealthy lawyer in his fifties, attempts to reconnect the two ends of his life by recounting his childhood memories, his time in seminary, and his marriage to Capitu. At the heart of his narrative lies his morbid jealousy and suspicions of adultery. But can readers trust this unreliable narrator's version of events? The novel leaves the central question of Capitu's guilt deliberately ambiguous, inviting multiple interpretations.
