The Heritage of the Desert Grey, Zane Pearl Zane Grey (January 31, 1872 - October 23, 1939) was an American author best known for his popular adventure novels and stories that were a basis for the Western genre in literature and the arts; he idealized the American frontier. Riders of the Purple Sage (1912) was his best-selling book. In addition to the commercial success of his printed works, they had second lives and continuing influence when adapted as films and television productions. As of 2012, 112 films, two television episodes, and a television series, Dick Powell's Zane Grey Theater, had been made that were based loosely on Grey's novels and short stories. "BUT the man's almost dead." The words stung John Hare's fainting spirit into life. He opened his eyes. The desert still stretched before him, the appalling thing that had overpowered him with its deceiving purple distance. Near by stood a sombre group of men. "Leave him here," said one, addressing a gray-bearded giant. "He's the fellow sent into southern Utah to spy out the cattle thieves. He's all but dead. Dene's outlaws are after him. Don't cross Dene." The stately answer might have come from a Scottish Covenanter or a follower of Cromwell. "Martin Cole, I will not go a hair's-breadth out of my way for Dene or any other man. You forget your religion. I see my duty to God."
