This book, written by a man that built two very separate writing careers, was very interesting. I had read both some of his fantasy works, including the odd legendary book, Silverlock. I had also read some of his other historical works. Both type of book tend to be very literary and require the reader's attention, and this is no exception.
This book cuts through many of the legends about Doc Holliday, but leaves some flexibility, because there is really no solid evidence one way or the other about some of the stories. Even Wyatt Earp, one of his best and most constant friends for years, was unaware of his whereabouts when he died, and this book helps explain that. There is also no accurate total for the number of men that he shot and/or killed, but he was clearly innocent in the only case that was ever brought to court.
His life intertwined with that of the Earps, but also with everyone from Bat Masterson to Johnny Ringo.
The book also untangles the chronology of such events as the O.K. Corral gunfight, and shows where most of the movie versions got it wrong. I've seen revisionist historians try to explain how the Earps were in the wrong, and the Clantons pure and innocent, but this punches plenty of holes in those ideas.
This book is not long, but isn't one to rush while you're reading, because it includes some wonderful snippets from the press of the 1870s and 1880s. Some reviewers complain that the text is written in an archaic style that makes it harder to read, but I have to argue that this makes it more suited to the subject and the era in which the story took place.
I highly recommend this book if you're interested in the gritty side of the American West, with its gunfighters, gamblers, miners and whores in the boom towns, alongside the honest cowboys, rustlers, lawmen, and just regular folks trying to get along.
