Devil's Kin — Charles G. West

Jordan Gray rode with a posse of townfolk to track a gang of killers. While out looking for the killers, they doubled back and struck his homestead, slaughtering his entire family. Unwilling to wait for the town to form another posse, Jordan goes after the gang by himself. As bad luck would have it, the law in Fort Smith mistake Jordan as one of the gang, and he is forced to make his escape. He is now the hunted as well as the hunter.
