Ivan Katić, an idealistic intellectual and former World War I veteran, faces a spiritual and existential crisis in interwar Serbia. As the country struggles with political turmoil and the rise of communist ideas, Ivan finds himself torn between his beliefs, family expectations, and societal pressures. His search for truth and justice brings him into conflict with his friends and family, while he struggles with feelings of guilt and "sin" for his nonconformist views. At the same time, the novel depicts broader social conflicts—from class tensions to political conspiracies—through the fates of characters like Bogdan Dragović and Milena Katić, who embody different ideologies.

Ćosić's rich, introspective style and detailed historical background make The Sinner a powerful portrayal of moral and ideological conflict. The novel questions the nature of sin, sacrifice, and personal responsibility in times of political polarization. Appreciated for its psychological depth and authentic portrayal of Serbian history, The Sinner is a key work in the Time of Evil trilogy, which resonates deeply with themes of humanity and resistance.
