"Violence and rumored rebellion had turned the border country into a powder keg primed to explode at any second. The mysterious "Liberator" called for war - and men who spoke against him died suddenly! Walt Slade, undercover ace of the Texas Rangers, rode into Matamoros, a one-man task force with the deadly job of stopping a revolution before it started. For Slade knew that "The Liberator" was none other than Veck Sosna, the most ruthless outlaw Texas ever spawned! Danger lay ahead - but even Slade could not foresee the terrible ordeal that faced him on the Trail of Blood and Bones."--,Provided by publisher.
