According to the cover blurb, this novel is the way Zane Grey wrote it before it was edited by the publishers, with parts of another novel added. And supposedly even that version was made into several movies. The Ranger-Rustlers part is very interesting. However, as the novel was written in 1914, the story of the two love interests---two lawmen and two eastern women---borders on the melodramatic prose of the period.
1994 edition of 1913 cowboy classic. One of the books that makes up the Lone Star Trilogy. Western writers of today owe a lot to Zane Grey. Blurb inside front cover: As he strode in he saw Duane. "Hell's fire!" he cried. The guns boomed simultaneously.
