They reach Dhiru Kaka's house. In the evening, while having tea, they have a visitor named Dr. Srivastav, who is an osteopath and a good friend of Dhiru Kaka. Dr. Srivastav tells Dhiru Kaka that last night a daku (dacoit) had broken into his house. He believes that the dacoit must have come to rob a precious ring given to him by Pyarelal Seth, because he had saved the life of his only son. He further tells that when Pyarelal had his second heart-attack, Pyarelal murmured "a spy", before ultimately dying. Dr. Srivastav tells that robberies do not happen much in his neighborhood due to the presence of Bonobihari Sarkar, who owns a private menagerie with a variety of poisonous animals. Dhiru Kaka tells Feluda that the ring once belonged to the Mughal emperor Aurangzeb. Dhiru Kaka offers to keep the ring with him. Later, when Dr. Srivastav leaves the house, Feluda sees a car following the doctor's car. Feluda tells Topshe that somebody had been listening to their conservation, because Feluda finds a half-burnt cigarette in the garden.
