Deeply researched, well written account of a decade of murders of wealthy Osage Native Americans. A series of horrific crimes, conspiracies and cover-ups that is not well know - but should be! The author dove deep into official and unofficial documents to research his work. His findings went beyond accepted facts about the case (such as the number of killings and the length of time they occurred over). The book does not read like a recounting of facts, it reads more like a thriller - just as officials think they have the killer(s) there are twists and turns, leaving local and federal - the newly formed Hoover FBI- starting over from scratch. We meet the victims, the lawmen (my favorite was Tom White - a character who deserves his own movie!) and the perpetrators, then we also meet the descendants of the victims.The crimes were sinister and the cover-ups evil brilliance. The Osage, who had been forced to barren Oklahoma lands were the recipients of mining/mineral rights and then oil was discovered. They become the richest per capita people in the world at the time, and yet the Federal Government deemed it necessary to appoint guardians to each of them and deny them the right to manage their own funds. Their neighbors were extremely jealous of their wealth, their guardians largely scammed them, and these factors led to the evil plot to gain their wealth. To add insult to injury further "scamming" may be taking place now in the present time. Shameful.Note -About 2/3 thru the book it feels like the story is pretty much wrapped up, but keep reading because the story continues to the present day!
