Not every Western hero wears a white hat or a tin star. Most of them are just fighting to survive. Some of them can be liars, cheaters, and thieves. And then there's a couple of old-time robbers named Slash and Pecos . . . After a lifetime of robbing banks and holding up trains, Jimmy "Slash" Braddock and Melvin "Pecos Kid" Baker are ready to call it quits-though not completely by choice. Sold out by their old gang, Slash and Pecos have to bust out of jail and pull one last job to finance their early retirement . . . The target is a rancher's payroll train. Catch is: the train is carrying a Gatling gun and twenty deputy U.S. marshals who know they're coming. Caught and quickly sentenced to hang, their old enemy-the wheelchair-bound, bucket of mean, Marshal L. C. Bledsoe-shows up at the last minute to spare their lives. For a price. He'll let them live if they hunt down their old gang, the Snake River Marauders. And kill those prairie rats-with extreme prejudice . . .
