After reading Doc by Mary Doria Russell, I wanted to delve a bit deeper. I only wish I'd read this first, as the "backstory" would have further enhanced my enjoyment of the novel. I enjoyed reading about the development of the frontier mining town of Tombstone and all the economic, political and social factors that played a role. This is well researched with extensive notes on where and how Guinn obtained his research. I really appreciated his explanations of where his source material came from and the problems inherent in many of the contemporary accounts.
