All Western Winners #3

An overturned stage coach brings an injured Peter Henderson into the care of Doctor Masters. Unscrupulous businessman Ben Jonas learns that Henderson, a courier carrying sealed bids for a construction project to Washington, is laid up for a day or so and gathers his henchmen to steal the bids so he can underbid and get the project. In the process of stealing the bids at gunpoint Marie Lathrop is taken as insurance against anyone following. Masters changes to the Black Rider and successfully takes down the gang, with Jonas paying the ultimate price. Marie gets her first kiss from Black Rider.
