Longarm and the shotgun man

About “Longarm and the shotgun man”

Deputy U.S. Marshal Custis Long takes an undercover assignment riding shotgun for a robbery-plagued stagecoach line, pursuing a gang with four stolen stashes and four dead guards to its name. Protecting a blond heiress and a prissy city lady only makes his job twice as hard as the marshal and passengers become pinned down far from help.
