Vengeance at Sundown — Larry D. Sweazy

Lucas Fume has had plenty of fights in his life: spying for the Confederate Army, standing up to the railroad company when they tried to take his land, then getting framed for the murder of his business partner--only to lose his land as well as the love of his life. But Lucas isn't finished fighting yet...

With help from Ezekiel 'Zeke' Henry, a fellow inmate and former slave, Lucas manages to escape prison. Riding with Zeke to St. Louis, he soon discovers that his former partner is still alive, using a different name, and doing big business with the railroads--and he has Lucas's lost love with him. On the run from the law and up against a rich and influential enemy, Lucas is about to take on the most dangerous fight of his life.
