Tom Holm, Native American scholar at the University of Arizona, fashions his debut novel in post-Great War Oklahoma, where oil exploration and exploitation were seriously at play. Ex-cop J.D. Daugherty sets up shop as a P.I., and he and his Cherokee sidekick, Hoolie Smith, are hired to track down a runaway couple: a wealthy heiress and a young Native American, who also happens to be an heir to Osage tribal oil. Murder, race riots, and shootouts are various features of the mayhem Holm includes in his rigorously researched and well-crafted crime story. It’s the kind of book a progressive history teacher would include in their curriculum.
