Idaho gold fever
(Book)

"Skye Fargo runs across a wagon train being 'guarded' by some low-down men in the employ of one Victor Gore, a man who makes his money at others' fatal expense. With Gore and his vermin on one side and a band of angry Nez Perce Indians on the other, the Trailsman has to guide the settlers to their promised land, or they'll be buried in it"--Publisher.
