Glory Dust by Robert Vaughan
Once they fought on opposite sides of a war. Now they're fighting for justice and revenge!
They Came from one Missouri family, but Lance and Buck Chaney had been fighting on opposite sides of the war—until they were brought together ba a shipment of gold dust. Fighting for the Confederacy, Buck had been ordered to hijack the gold his brother's Union troops were bringing north to Jefferson City. By the time the skirmish was over the shipment of gold was missing. Now the former enemies have joined together again—to hunt down the man who had taken the gold from them both in an act of treachery and bloodshed.
