Like other great nineteenth century novels, Machado de Assis's Dom Casmurro explores the themes of marriage and adultery. But what distinguishes Machado's novel and what makes it such a delightful discovery for English-speaking readers, is its eccentric and wildly unpredictable narrative style. As he recounts the events of his life from the vantage of a lonely old age, the narrator Bento continually interrupts his story to reflect on the writing of it. But the novel is more than a performance of stylistic acrobatics. It is an ironic critique of Catholicism, in which God appears as a kind of divine accountant whose ledgers may be balanced in devious as well as pious ways. It is also a story about love and its obstacles, about deception and self-deception, and about the failure of memory to make life's beginning fit neatly into its end.
