Finally, everything is revealed: Umanath Ghoshal's son, Rukminikumar (a.k.a. Ruku) got to know that Maganlal was planning to steal the Ganesh statue, so he hid the Ganesh statue in the idol of Maa Durga's Lion. Shashibabu, while painting the lion got the statue and handed it to Bikash—without knowing his involvement with Maganlal—before going home because of his sudden illness. Afraid that Shashibabu would reveal everything and would unintentionally ruin his plan, Maganlal sends a henchman with Bikash to liquidate Shashibabu. The henchman with the help of Bikash, tracks down Shashibabu, murders him brutally by stabbing him and disposes off the knife in the Ganges. Subsequently, after an intricately planned sting operation, Maganlal and Machhli Baba are arrested by the Varanasi police. The story ends with Lalmohan Babu realising that Ruku's plan of hiding the statue inside Maa Durga's Lion idol actually came from one of his own thriller novels and Feluda praising him for creating such an idea.
