At Prairie's End

Description for AT PRAIRIE'S END by Robert J Horton:

John Campbell was once an outlaw but now leads an honest life as a rancher in the Pondera area of Montana. He and his wife Jane live on a ranch that is on government land, but this year he will be given an ownership patent. Sheriff Tom Lane is Campbell’s ally and worries, as does Campbell, that some of Campbell’s former associates may seek him out and cause trouble.
