lighter than it should be. Ghote tries to take the bottle as evidence but Carstairs drops it. Under threat of arrest for destroying evidence Carstairs tells Ghote that he dropped the bottle out of shock, having realised that the only key for the dispensary is in his charge. After the interview Ghote encounters Dr Uplea who tells him Carstairs is not normally so clumsy and confirms there is only one key to the dispensary. Dr Uplea also reveals that she had "Edward G." and "Tarzan" watch on the dispensary as her car was nearby and had been recently vandalised. Ghote interrogates "Edward G." by playing along with the boy's obsession with movies. The boy tells him that he saw a man enter the dispensary with a key. Using a ride in a police wagon as a bribe, Ghote discovers that the man was Amahred Singh, who has a gold smuggling racket which the boys help with. Masters apparently found some of the gold and locked it in the dispensary. "Edward G." promises to arrange a meeting between the inspector and Singh. Ghote calls the fingerprint department and learns that Singh's fingerprints were found in the dispensary. A new interview of Sonny Carstairs, with intimidation, confirms that Carstairs gave Singh the key to dispensary because Singh threatened him. Later the same evening Chatterjee Krishna blackmailed Carstairs for the key with the knowledge that Carstairs used ether as a recreational drug. Chatterjee admits borrowing the dispensary key but then flees. Ghote gives chase and captures Chatterjee who admits entering the dispensary but denies killing Frank Masters. Ghote reluctantly accepts this. "Edward G." keeps his promise: Singh arrives and begins to answer Ghote's questions in a good-natured way. He charmingly acknowledges that he is a criminal and that the police want to hang him. Ghote tries to obtain a confession that Singh entered the dispensary. Singh refuses to give an explanation of why he was in the dispensary and notes that even he is a little afraid of Doctor Diana Uplea. The following day Ghote has an interview with the Deputy Superintendent of Police. Ghote is ordered to have Singh arrested, with false evidence if necessary, and to suppress evidence that implicates Chatterjee. The D. S. P. leaves Ghote with a warning not to be too clever. Instead of following orders, Ghote interviews Dr Uplea again. Frank Masters' visit to the Punjab is
