The Palo Duro was bad country: dry as the rattlesnakes that owned it, mean as the Comanches who ruled it, wild as the outlaw town of Hell that was its capital. Dusty Fog had ridden in and shot his way back out again. But had left behind men and women at the mercy of the Kweharehnuh Comanches. Bad men, who had committed almost every kind of crime, and women who were not much better, it is true. That did not stop Dusty feeling concerned for their safety. So the Rio Hondo gun wizard decided that he must go back to Hell. Despite all the dangers which doing so entailed, the Ysabel Kid and Waco insisted upon accompanying him. The mysterious man called Break O'Day rode with them—but he intended to be the only one to come out of Hell alive.
