Read Bushwack Bullets Storyline:
Hap and Everett, adopted children of the Yaqui County sheriff and his wife, where known as the Kingman twins. Actually Hap was the son of the upright rancher Warren Allen, who had been killed by bushwack bullets, while Everett's father was the ruffianly cattle thief, Dev Hewett. The boys were ignorant of their own identity until they came of age. And then, for reasons of their own, the crooked lawyer entrusted with telling them the truth pretended that Hap was the rustler's son, and gave to him Hewett's legacy: a six-gun, and instructions to use it to murder Dev Hewett's ancient enemy.Pages of Bushwack Bullets :
