McAllister Trapped (A Rem McAllister Western #20‪)‬

When McAllister arrives in Limber he takes an instant dislike to the drab, melancholy mining town. He'd smelled a rat immediately he was offered the job of Chief Marshal, and he's soon to find out that his unfailing instinct is once again on target. For the unsavoury fact is that the man who owns the town, the mine, the mayor, the law officers and the starving miners is trying to buy him, too. And for why? To prevent with bullets and terror the possibility of a violent, bloody strike.
When McAllister refuses,he becomes trapped. The bosses want him removed on suspicion of siding with the slaves - and the slaves cannot be convinced that he is not gun-slinging for the bosses. The only alternative is to leave town fast.
But McAllister isn't about to be 'persuaded' by anyone ...
