When Charlie Askins died one of the gun scribes put out a note to the staff that said "Hell just got fuller." Unrepentant Sinner is a tough read its like Cormac McCarthy's carnage filled Blood Meridian novel but for real, only can read it in short bursts.
Askins wrote some pretty good books though, esp. his early stuff, I am reading his "The Pistol shooter Book" now which is a deep study of the guns and shooting arts of the early 50's, it also has a lot of the stories that he retells in Unrepentant Sinner with less restraint. The book features stories about George Parker a pistolero pardner of Askins.
Reading Askins is like reading John Westly Harding's bio, Askins- imo was the same type of man, and Askins for sure had more notches on his guns than any gun writer in any era.
There is a 20 some page thread over on "The High Road" about Askins if any one is interested..
