Mata Dhinn and Bira Shah, two Gond hunters who met Biggles told him that their colleague Ram Shan had seen the camp of Captain Toxan before but he would not leave his village to show Biggles the way because a tiger was terrorizing his village and he had a wife, children and goats to protect.
To gain his cooperation, Biggles and Bertie had first to journey to the Gond village to eliminate the tiger. After this was done, Ram Shan led Biggles and Bertie to the Nullah Tangla where they found Toxan injured. They later rescued Mr Poo Tah Ling from Chinese soldiers who had captured him. Subsequently Ram Shan assisted in evacuating the party from the nullah, carrying the injured Captain Toxan to the lake shore where they were able to board the Gadfly and depart from the scene.
