The Rio Hondo Kid — J.T. Edson

The hired gunmen came to Mahon’s place to take him away and kill him. But instead of Mahon they found a black-dressed Texas boy with a fast gun, and left him for dead, taking his horse. They had made their first big mistake. In the town of Escopeta they met two more Texans, one a handsome blond giant, the other a small insignificant-looking individual, the sort of man one would pass in the street without a second glance. The hired gunmen passed him without a second glance and in so doing made their second, and biggest, mistake. For the small man was none other than the famous Rio Hondo gun wizard, by name of Dusty Fog.
