Besides his reputation as the deadliest man with a six-gun, he left an autobiography in which he detailed many of the troubles of his life. In A Lawless Breed, Chuck Parsons and Norman Wayne Brown have meticulously examined his claims against available records to determine how much of his life story is true, and how much was only a half truth, or a complete lie. As a killer of up to forty men, Hardin obviously had psychological issues, which the authors probe and explain in laymen's terms. To Hardin, those three dozen or more killings were a result of being forced to defend his life, his honor, or to preserve his freedom against those who would rob or destroy him or his loved ones. Was he a combination freedom fighter/man-killer, or merely a blood-lust killer who became a national celebrity? This deeply researched biography of Hardin and his friends and family will remain the definitive study for years to come.
