Forced from their ancestral home to the rocky plains of Oklahoma, the Osage Indian nation seemed headed toward a reversal of fortune when oil was discovered under their land. Indeed, in the 1920s many of the Osage were among the richest people in the country. But then they started dying and, despite the suspicious circumstances, local law enforcement failed to act. As the death toll rose, the newly formed FBI, helmed by a young J. Edgar Hoover, took over…and what they found was shocking. David Grann masterfully tells the riveting, devastating story of this bleak chapter in American history, uncovering new evidence about the Osage killings and weaving a narrative so full of suspense and emotion that you'll fly through the pages, even as you shudder at the near-incredible depths of this horrific conspiracy.
