Murder in Harrill Hills is the third non-fiction and second true crime book by R. S. Allen, the first two being SCHOOLBOY – Jim Tugerson: Ace of the ’53 Smokies and The Perry’s Camp Murders (with Steve O. Watson), both published by Infinity Publishing.com. Allen, who grew up in East Tennessee, is a retired FBI Agent who investigated crime in Miami, Atlanta, and Baltimore before returning to the foothills of the Smoky Mountains. The author turned to investigative writing following a stint of several years as an innkeeper. Since selling the inn, writing about actual events not thoroughly explored and documented have captured his attention.
