A review of Riders of the Purple Sage by Zane Grey (New York: Harper & Brother, 1912). Ebook.
Jane Withersteen is a wealthy, young Mormon woman in Utah. The local Mormon churchmen harass her because she befriends Gentiles (non-Mormons), and because she refuses to marry an elder named Tull, who wants to make Jane his third wife so he can acquire the considerable property and cattle she inherited from her father.
Tull and his men grab one of Jane's cowboys, Bern Venters, a Gentile, intent on whipping him out of their territory. But a rider dressed in black arrives on the scene, frightening the Mormons into leaving. This new man is Lassiter, an infamous gunfighter and hater of Mormons. He is searching for the grave of his sister, who had been taken from her home and brought to Utah to become a Mormon wife. Jane resolves to use her kindness to influence Lassiter to give up his life of violence.
When cattle rustlers steal one of Jane's herds, Bern rides out in pursuit. He gets into a gunfight with two of the thieves, killing one and wounding the other. He is shocked to discover that the latter is a feared rustler known as the "Masked Rider"—and a young, unarmed woman named Bess. In remorse, they hide in a cave in a secluded valley while he nurses her back to health. After some time, they fall in love.
