The renegade gun / Ray Hogan.

Was it vengeance, hate, or just plain cussedness that brought John Cameron back to Wolf Springs? Whatever it was, it meant trouble and bloodshed - something the townsfolk wanted to avoid at all costs. They'd been reduced to a quaking band of yellow bellies by Sid Mason and his rough-riding cohorts and feared being caught in the crossfire of a range war certain to erupt if Cameron stayed. From his cold reception in town, Cameron reckoned that his only ally in the coming battle to regain his land, his cattle, and his girl would be found in his holster. He'd expected as much and wasn't fool enough to discount the odds against him, though he hoped that a few of the independent ranchers would throw in with him if only to stave off Mason's relentless drive to turn the whole valley into his private domain. Regardless of the help he did or did not receive, Cameron's purpose was clear, his resolve fixed. He had a score to settle and would see it through - to the bloody end. Sid Mason had built up his immense Muleshoe spread by coercion and theft. Now one man alone swore to stand up to Mason in a war that threatened to set the whole territory ablaze.
