The Brothers Karamazov is Dostoevsky's final novel, exploring profound themes of faith, free will, morality, and the nature of human existence. The novel follows the lives of the three Karamazov brothers, each representing a different philosophical perspective: Dmitri, the passionate sensualist; Ivan, the intellectual skeptic; and Alyosha, the spiritual and devout monk. At the heart of the story is the murder of their father, Fyodor Pavlovich, and the subsequent investigation into the crime, which challenges the brothers' beliefs and their relationships with one another.
