Publisher's Synopsis
The hooded Faceless Riders had spread a trail of terror and death along the Rio Grande. Striking where they were least expected, the outlaw band had thrown the whole territory into panic. And the toll from their guns was overflowing Boot Hill.
As the ace undercover Ranger Walt Slade rode into the Border country, he knew that only one man could rod a gang so ruthlessly. And that man was Slade's bitter arch-enemy Veck Sosna, the cleverest, most notorious outlaw Slade had ever faced!
Slade knew that the stakes were high. For if he didn't beat Sosna the whole Border country would crumble from law and order into the chaos of gun justice. And he knew, too, that if he lost this battle it would be his last. For there was another tombstone waiting in Boot Hill, marked with an S -- Slade or Sosna!
