The Gambler. Bailey Clan Westerns, #18

A card game can be deadlier than a gunfight. Corey Bailey has spent his life drifting between poker tables and dusty trails. Trained by a master gambler in his youth, and drifting after the bitter Civil War, all he ever wanted was a ranch of his own and a reason to stay. Wherever he goes, trouble follows, with an unwanted reputation of a gunslinger. In a small Utah town, Corey sees a chance to disappear, but stumbles into a bitter range war between a powerful rancher and nesters.
Standing aside isn't in his nature, even when the odds are stacked against him. A story of reputation and resolve, THE GAMBLER is the 18th book in the Bailey Clan Westerns series by Terence Newnes.
