Twister Malone and Chuckaluck Thompson can't catch a break. All they want is a trail to follow straight through to Mexico, where a ranching job offers honest work, peace, and quiet. But no matter how fast they ride, trouble keeps hot on their heels. A gunshot breaks the silence of the lonely wagon road. By the time Twister and Chuckaluck reach the corpse, the killer is long gone. In the victim's pocket they find a letter from a woman begging for help, a woman whose savior now lies dead in the alkali dust. Twister and Chuckaluck have no choice but to take up his mission--even if it means facing down the quickest draw they've ever been up against.
