The Virginian - Season 2 Episode 4 A Killer in Town

A bounty hunter named George Wolfe (Broderick Crawford) comes to Medicine Bow, having been summoned by a now dead informant who told Wolfe a fugitive is in town. Although the informant had left a letter revealing the fugitive's identity in a lock box at the bank it can not be accessed until the circuit judge can return and issue a court order. Trampas, who had accidentally become involved with some felons two years before, thinks he is Wolfe's quarry and Wolfe is suspicious of him. Before matters can come to a head, however, an outbreak of typhoid fever intervenes.
