Rogue law

the long version

"The corrupt town of Montero wanted Julius Lang as marshal, but he refused the work as too dangerous and no job for an upright man. When persuasion didn't work, the town took Lang's ranch from him. And when pretty Matti Ullman arrived to lay claim to his land, Lang, needing to earn a living, was forced into the marshal's job. So Montero got Lang as their marshal - and they expected compliance - but what they got was rogue law."--Publisher description.
