Arizona Ames

This late-period Zane Grey is one of the best of his novels. Rich Ames didn't set out to be a gunslinger - it was forced on him. After the bad guys try to "ruin" his twin sister Nesta, Ames grabs his pistols and the bloody gunfight follows. Unfortunately, his criminal actions force him to flee from his beloved Nesta and his happy Tonto Rim home, pursued by the law.
