In the title story, "Big Medicine" old Billy Dunbar has discovered some great gold-bearing gravel -- but at the same time, he's also discovered 9 Apaches. If they catch sight of his burros or his prospect holes, Billy's a goner. Emmet Fisk and Gus Mathis were minding their own business when Dusty Barron made a break from killing a man in the saloon and the two men were blocking his escape route.
