A twisting, haunting true-life murder mystery about one of the most monstrous crimes in American history. In the 1920s, the richest people per capita in the world were members of the Osage Indian nation in Oklahoma. After oil was discovered beneath their land, they rode in chauffeured automobiles, built mansions, and sent their children to study in Europe. Then, one by one, the Osage began to be killed off. As the death toll climbed, the FBI took up the case. It was one of their first major investigations and the bureau badly bungled the case. In desperation, the young director, J. Edgar Hoover, turned to a former Texas Ranger named Tom White to unravel the mystery.
