A long, black car slid along the country road with the silent, effortless speed of an aeroplane's shadow. Leaning back against the soft cushions in the luxurious motor, the Fat Man couldn't help but wonder why the millionaire, Vernon Kinsley, had enlisted the services of a private detective... In Cairo many years ago he was in business with his son-in-law Mr Ringo engaged in selling certain supplies to the Egyptian army. Most of their dealings were with a Captain Stoner. Through certain carelessness on the part of Stoner they were able to make considerable profit but as a result Stoner was court martialled and dishonorably discharged from the army. Now Stoner blames them and has appeared suddenly and threatened Vernon Kinsley life.
