Storyline

Pradosh C. Mitter AKA Feluda, Topshe, and Lalmohan Ganguly go to Puri for vacation. One evening, the trio spot odd footprints on the sand. Later, Lalmohan goes to meet Lakshman, an astrologer who is presumably gifted with extrasensory perception. Soon they stumble upon Roopchand's dead body lying on the beach. Feluda figures out the mystery and gathers everyone at Bhujanga Niwas and tells everyone that Bilas Majumdar is actually Animesh Kumar Sarkar, a smuggler by profession. Feluda tells them that the actual Bilas Majumdar had died three weeks ago in a hospital in Nepal. Why?
