Biswas Ghatak

Biswas Ghatak is one of the most acclaimed Bengali spy thrillers by Narayan Sanyal, masterfully blending historical fact with gripping fiction. Set during the backdrop of the Cold War and global espionage, the novel tells the story of Klaus Fuchs, a brilliant physicist whose betrayal changed the course of world history.

Fuchs, a real historical figure, passed nuclear secrets from the Manhattan Project to the Soviet Union—earning him the label of "traitor" or "whistleblower", depending on perspective. Through meticulous research and vivid storytelling, Sanyal explores the moral complexity of espionage, patriotism, science, and ideology.

Biswas Ghatak is not just a thriller—it is a thought-provoking novel that questions the thin line between loyalty and betrayal in the high-stakes world of international politics.
