Khushwant Singh stands as one of the most distinguished writers in contemporary Indian English fiction, recognized for his profound commitment to social realism and unflinching critique of Indian society. This paper analyzes how Singh employs an unvarnished style, characterized by wit, humor, and candor, to expose the complexities, contradictions, and hypocrisy prevalent in modern India. Focusing on selected novels—including A Train to Pakistan (1956), I Shall Not Hear the Nightingale (1959), Delhi: A Novel (1990), and The Company of Women (1999)—the analysis explores his critique of historical trauma, political corruption, communal tensions, and shifting morality. Singh utilizes literature as a mirror to reflect the painful realities of life, such as the devastation of the Partition, the intricacies of the Sikh ethos, the failure of political leadership, and the candid exploration of human sexuality. Ultimately, Singh’s work is characterized by its powerful blend of satire and deep humanistic concern, ensuring his legacy as a courageous chronicler of modern Indian life.
