Feluda, along with his cousin Tapesh takes a summer holiday to Gangtok. There they meet a man named Sasadhar Bose, he is on a business trip to look for aromatic plants. They hear people talking about an accident, and when they inquire they find out that a man had been killed in a sudden accident by a falling rock on the road. Mr. Bose discovers that this man was his business partner, Mr. Shivkumar Shelvankar. At the hotel they are staying at they met a man named Nishikanto Sarkar who sold a Tibetan statue Yamantaka Mr. Shelvankar. Later, Feluda and Topshe meet a German photographer who claims to be called Helmut Ungar but is actually the son of Mr. Shelvankar, Virendra. He is suspicious of the fact that the statue was not found with Mr. Shelvankar’s body. He tells them about a man named Dr. Vaidya, who claims to be able to read palms and predict future. They visit the Tibetan Institute to investigate about the statue. They discover that Mr. Bose is leaving for Bombay, so they ask him to investigate when he reaches. Virendra, or Helmut, shows them pictures that prove that Mr. Shelvankar’s death was not an accident. Using his powers of deduction, Feluda names Dr. Vaidya his prime suspect and he goes to Pemiangchi with Topshe, Helmut and Mr. Sarkar to find him. On the way, Sasadhar Bose, who had returned from Bombay, also joins them. The five then head towards Pemiangchi to catch Dr. Vaidya. On reaching there, Feluda learns that Dr. Vaidya had come to Pemiangchi, but has fled a day before Feluda reached. Surprisingly, he had left behind his walking stick, which he always used. Feluda then deduces, in front of the rest of the group, that Sasadhar Bose is actually Dr. Vaidya, who murdered Mr. Shelvankar to become the sole owner of their business. He also stole the Tibetan statue from the coat pocket of the dead Shelvankar. Bose tries to flee in the nearby jungles, and Feluda and Helmut find him attacked by leeches and capture him. He is later arrested by the police
