Search - Killers of Man

From the back cover:
Jeston Nash is used to dodging bullets, but when a hired thug's rotten remark gets under his skin, he can't let it go - and he makes himself an instant enemy aboard a snowbound train owned by the sleaze's boss, Ben Larr. A rich son-of-a-gun hell-bent on getting the grizzly who robbed him of a leg, Larr is a fouler piece of work than the usual brand of lowlifes Nash comes up against. When Larr blackmails Nash into leading his hunt, Nash discovers the killers of man in Larr's twisted domain - a netherworld filled with violence and drugs, obsession and revenge. Before long, he finds himself face-to-face with Laura, Larr's gorgeous but murderously manipulative wife, and one savage grizzly, a man-killer straight from the jaw of hell.
In a tale sparked with his trademark wit and bull's-eye historical detail, Ralph Cotton captures the essence of the Old West in the afventures of his extraordinary outlaw hero, Jeston Nash.
