On a long railway journey, a group of passengers begin debating love, marriage, and the condition of modern society. Among them sits Pozdnyshev, a reserved man who gradually reveals that he has lived through a marriage marked by mistrust, resentment, and mounting emotional strain. As his confession unfolds, what begins as social conversation turns into a disturbing account of domestic intimacy, jealousy, and suspicion. First published in 1889, The Kreutzer Sonata is one of Tolstoy's boldest and most provocative shorter works. Written with psychological force and moral intensity, the novella examines marriage, sexuality, hypocrisy, and the corrosive power of possessiveness. Its compressed structure, confessional voice, and unsettling philosophical edge give it a rare and lasting power.
