For readers of his book, Corbett often feels like a detective. He would get requests, studied it, gathered evidence, interviewed villagers, walked the terrain to piece together the behaviour of the individual animal. With no camera traps or drones but instinct and skill, he identified the exact animal responsible for attacks. His hunts saved countless lives in Kumaon and Garhwal. The Champawat tigress, responsible for over allegedly 200 deaths, remains one of the most chilling man-eater cases in history. He also killed Panar, a leopard who had also reportedly killed over 400 people in India.
