Slocum and the Diamond City Affair (Slocum, No. 405)

Slocum’s about to turn a couple of no good horse thieves into glue.

Slocum had just ridden into Diamond City, but with hardly a chance to clean his whistle, a man approaches him with a job. Casey O’Riley lost two rare breed racehorses—and his wife—to a couple no good outlaws. He’ll pay top dollar to get the horses back. For his wife, he’ll do just about anything.
 
Now, Slocum’s on the trail with O’Riley and a lovely señorita named Rosa along for the ride. And despite a several day head start, the no good horse thieves find themselves neck and neck with the last man they’d ever want to cross.
