The Tale of the Devil represents the first biography of Anderson "Devil Anse Hatfield," written by great grandson Dr. Coleman Hatfield, and noted Mountain State historian Robert Y. Spence. The title is now in its third publishing and has remained an Appalachian best-seller. The Tale of the Devil is the story of Hatfield patriarch Devil Anse Hatfield, beginning with his childhood in frontier Appalachia; it also covers his Civil War days as a Confederate soldier and leader of the Wildcats militia. The 320-pages will also enlighten the reader of the true story of the Hatfield-McCoy feud, the violent killings, and the post-feud years after the fighting ceased.
