After the plan to get Griffin arrested failed, Dr. Kemp informed Colonel Adye that Griffin was mad. He further told him that Griffin must be stopped or he will next turn to killing people. Dr. Kemp used the knowledge given to him by Griffin against him. He wanted that every available man should be put to hunt. He wanted to stop Griffin from escaping. He knew that the only thing that could stop him from leaving the place was his three books. Dr. Kemp said that they must stop him from eating or sleeping and every single person should be on alert. Dr. Kemp further said that they should use dogs as they could smell him. Another important thing was that the food eaten by Griffin was visible until it had been absorbed. He also wanted powdered glass on the roads to trace Griffin's feet. But finally Dr. Kemp succeeds because of people's help.
