Pragyasutra by Krishnendu Mukhopadhyay [Hardcover]

"Two thousand five hundred years ago, the great Ashoka established a secret society with nine unknown scholars to practice supreme knowledge in nine different subjects. Many believe that this secret society still exists today. Based on this premise, Sahil writes a Hindi movie script. As producer Roshan Mehta does not like it, Sahil goes to North Kolkata to meet historian Amarendranath Sikdar for more information. In the novel 'Prajna Sutra', there are two parallel stories. The first story is Sahil's thriller screenplay, where three elderly men, Prithwish Mitra, Bishwanath Karmakar, and Achintya Bady, reveal one mystery after another about the secret society from two thousand five hundred years ago. In the other story, as Sahil narrates this thriller bit by bit to Amarendranath Sikdar, the trajectory of the screenplay begins to change. In this gripping novel, another mystery is ultimately revealed."
