They escaped their execution—but there’s no escaping Slocum.
Everyone in Sublette County wants to see Angus Dingo and Flatnose Nelson hanged—everyone including John Slocum. Their brutal crimes warrant their deaths, but when their hour is up, they are nowhere to be found.
 
Slocum aims to track down the convicts and finish the job himself. As good as he is, these two won’t be an easy catch—especially...

WILD JUSTICE. Wesley Putnam was Head Detective for the Arizona Cattlemen's Association, and the best friend Slocum ever had ? until four fugitive rustlers burst into a cantina and gunned Wesley down in cold blood. All Slocum got from the dying friend was a vague description of the gunmen, and all he gave in return was a solemn pledge: to pursue these men to the ends of the earth if necessary, and to judge them by the ancient law: blood for blood....

During a visit to Harleyville, Slocum becomes caught in the middle of a range war as the two conflicting sides compete for his talents, but the situation turns even uglier when one of the West's most notorious gunfighters, Aaron "One Shot" Parsons, arrives in town.

When his saddle partner disappears after striking gold, Slocum, along with his six-shooter, sets out to find the truth, which leads him to stunning, yet untrustworthy Russian duchess who holds the key to the mystery.
