Mashrur Arefin: Architect of Modern Bangla Fiction is a comprehensive critical study of one of contemporary Bangladesh's most innovative and intellectually daring novelists—Mashrur Arefin. Written by Milton Biswas, this book situates Arefin's literary career within the broader histories of Bangla fiction, global modernism and postcolonial thought. Blending biography, textual analysis, philosophy and cultural history, the book traces Arefin's evolution from his formative years in Barishal and Khulna to his cosmopolitan intellectual engagements with Borges, Homer, Kafka and world literature. It explores how myth, memory, rivers, political violence, sexuality and ethical truth converge in his fiction—especially his fictional interrogation of the 1975 assassination and its long shadow over Bangladeshi political consciousness. Equally attentive to aesthetics and ethics, this study highlights Arefin's dual life as a banker-poet and examines how professional modernity coexists with literary radicalism. The volume concludes by mapping his international reception and assessing his role in shaping the future trajectory of the Bangladeshi novel. Designed for scholars, students and serious readers of Bangla and world literature, this eBook stands as a definitive academic resource on Mashrur Arefin's revolutionary contribution to modern Bangla fiction.
