Benedict and Brazos 30

It looked like the end of the trail for Benedict and Brazos, when Brazos got mighty mysterious all of a sudden and just took off on his own. Benedict, the urbane gambler, reckoned he should be glad to be free of the lumbering Texas cowboy at last. Instead he missed having him around.
So he followed him, to find out just what his little secret was.
That was when the whole affair grew even more mysterious. Why did Brazos go all the back home to Wildhorse County, start throwing his weight around and bad-mouthing damn' Yankees at every opportunity?
It was all part of an elaborate cross and double-cross that would eventually see both men fighting for their lives against a bunch of fanatics who called themselves the Second Army of the Confederate States!
