Preston Diamond in Texas

1869. Four long years after the North-South conflict, Texas remains in festering turmoil. The Rangers have been disbanded. The failed Medicine Lodge Treaty has Indian tribes on the warpath. Corruption and racial violence draw Hell to the surface. Death and the Devil ride side by side. Robert E. Lee seeks government intervention to clean up thieves and Civil War relics who find life outside the law more palatable than hunger. On behalf of Texas cattlemen, Lee asks a personal favour from Washington's Chief Executive. Major Charles Graydon, of the Tumble G ranch, requests assistance from the United States Army. He receives one man: Preston Diamond. President Ulysses Grant's special emissary, Preston Diamond, has his first assignment. Can he salvage a faltering Texas cattle industry?
