This book retells the largely forgotten murders of several Osage people in the 1920s and how the case and its fame solidified the J. Edgar Hoover's control over the FBI and allowed him to shape it into the institution it is today. This book is DARK. It is broken into three parts, each with its own narrator. The first follows an Osage woman, Mollie Burkhart, as her family members begin dying around her. The second follows the lead FBI investigator, Tom White, as he and his team try and crack the case. The third follows the author as he researches the book, and learns that so many more Osage died than what the FBI ever investigated, and that the rot of the case goes so much deeper and the Osage community lives with the deep scars to this day, even as the rest of the world has moved on and forgotten. It's a tragic book, but very well written, and I liked the three narrator approach to the audiobook.
