This story, is more creative/nonfiction than historical novel in view of the weatlth of primary sources on both subjects of this two novella book: Big Nose Kate Elder and Viola Slaughter, wife of famous sheriff John Slaughter.
Author Coleman, has also written the historical novel on Big Nose Kate, Doc Holliday's Woman. This book is of the same quality and with the same historical insights from the family of Big Nose Kate. She was of minor Hungarian nobility, rather than the frontier floozie as which she is usually portrayed, such as by Fay Dunaway. Prior writers didn't even know Kate's real name, except for Glenn Boyer who discovered her family and real identity.
Well worth reading both for Coleman's captivating style and characterization and for historical insights.
