Frontier Justice — J.R. Roberts

One horse and three people don't add up to smooth traveling under the best of circumstances. And when one's a woman, one's a child, and both are in shock after a wagon train massacre. the going gets even rougher.

But Clint Adams has no choice. He's got to get the survivors to the nearest town for help. But someone's been backtrailing them every inch of the way. The Gunsmith doesn't know what the slippery stranger is up to -- but he'll bet his last dollar it's nothing good!
