Killers of the Flower Moon

Great book. I liked how it's split into three sections: the first is basically a history of the Osage and the many trials and hardships wrongly imposed upon them. The second focuses on the FBI's investigation into the murders, which would put just about any mystery novelist to shame with all the ups and downs and twists and turns. Lastly, the third section is about David Grann's visit to Osage land and how his own investigations unexpectedly turns up evidence that the crimes against the Osage were much, much worse than what the FBI unearthed.
