Osage County, Oklahoma, in the 1920s was where the richest people per capita in the world were to be found. The reason? Oil. After oil was discovered beneath their land, the Osage Indians had untold wealth. Then, one by one, they began to be killed off. The family of an Osage woman, Mollie Burkhart, became a prime target, her relatives shot or poisoned. And, as the death toll climbed, the FBI took up the case and began to expose one of the most chilling conspiracies in American history. Based on years of research and startling new evidence, this is a masterpiece of narrative non-fiction, as each step in the investigation reveals a series of sinister secrets and reversals. Killers of the Flower Moon is utterly compelling, but also emotionally devastating.
