Way of the Lawless by Max Brand

The bullets of the posse had neither torn a tendon nor broken a bone. Striking at close range and driven by highpower rifles, the slugs had whipped cleanly through the flesh of Andrew Lanning, and the flesh closed again, almost as swiftly as ice freezes firm behind the wire that cuts it. In a very few days he could sit up, and finally came down the ladder with Pop beneath him and Jud steadying his shoulders from above. That was a gala day in the house. Indeed, they had lived well ever since the coming of Andrew, for he had insisted that he bear the household expense while he remained there, since they would not allow him to depart.

"And I'll let you pay for things, Andrew," Pop had said, "if you won't say nothing about it, ever, to Jud. He's a proud kid, is Jud, and he'd bust his heart if he thought I was lettin' you spend a cent here."
