Trevanian explores the end of a dream - the Eternal West - and the end of a century. A young, mysterious stranger has arrived at Twenty-Mile - a fading town in the middle of nowhere. As he slowly insinuates himself into the lives of the townsfolk, questions abound, but answers are few. Then three more strangers show up in Twenty-Mile, including one of the vilest villains in the history of the Wild West. Incident at Twenty-Mile also subtly explores the harsh truths and bitter lies behind the myths of American expansion.
