Mexican Standoff — B.J. Lanagan

During the Civil War, they sought justice outside of the law, paying back every Yankee raid with one of their own. No man could stop them. No woman could resist them. And no Yankee stood a chance when Win and Joe Coulter rode into town.
 
Normally the Coulter brothers wouldn't pay any mind to some varmint's love life. But Win and Joe are down to their last dollars, so they agree to find the guy's long-lost lover, a little filly named Cat Clay. It seems like their easier job yet. Except that Cat is living smack-dab in the middle of a Mexican ranch war with bullets flying thicker than blazes. Now they have to find a ruthless killer, settle a ranch dispute, and rescue a very lovely lady in distress without ending up six feet under. All in a day's work for these two men from Missouri.
