What is the setting of The Orchard Keeper by Cormac McCarthy?

The book is set in the period between the two World Wars in Red Branch, Tennessee, a small mountain community just outside of Knoxville. An important aspect of the story's historical situation is the Prohibition movement and the related alcohol-related laws that followed it. Government regulation of alcohol makes obtaining alcohol either difficult or impossible through legal means, and thus Sylder gets involved in bootlegging rings which pay him quite well.
