This particular book I would call middle weight Zane Grey. It was fine in its own way, but pretty inferior to the last two I read, "Light of Western Stars" and "Last of the Duanes." It had a very appealing heroine, Molly Dunn, and an equally appealing bad guy gone good, her brother Slinger Dunn. The hero, Jim Traft, I found a cookie cutter not really tender tenderfoot character, typical of a number of hard boiled types that often crop up in Grey's novels. To his credit, Jim prefers duking it out with hist fists over the gun play that shocked Grey's editors back in the 1920s. I also enjoyed reading about the cowboys' tasks in building the controversial drift fence and the mayhem it engenders. Though "The Drift Fence" is one of Grey's Mogollon Rim novels, he doesn't constantly wax poetic about the scenery. This might make it more appealing to readers who are not fond of descriptive narratives such as you would find in "Riders of the Purple Sage."
