Killers of the Flower Moon delves into the haunting true-life murder mystery of one of the most monstrous crimes in American history. In the 1920s, members of the Osage Nation in Oklahoma were the wealthiest people per capita in the world, thanks to oil discovered beneath their land. They lived opulently with chauffeured automobiles, mansions, and European-educated children. However, a sinister series of events unfolded as they began to be systematically murdered.

The family of an Osage woman, Mollie Burkhart, was a prime target, with relatives being shot and poisoned. As the body count grew, the newly formed FBI stepped in, with the young director, J. Edgar Hoover, assigning former Texas Ranger Tom White to the case. White assembled an undercover team, including a Native American agent, to work with the Osage and uncover a chilling conspiracy.

Author David Grann presents a masterful work of literary journalism that captures the urgency of the mystery. Killers of the Flower Moon is not only a riveting account but also a searing indictment of the era's racial injustice.
