From the bestselling author of The Lost City of Z, now a major film starring Charlie Hunnam, Sienna Miller and Robert Pattison, and the Number One international bestseller The Wager, comes a true-life murder story which became one of the FBI's first major homicide investigations. 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. But the bureau badly bungled the investigation.
In desperation, its young director, J. Edgar Hoover, turned to a former Texas Ranger named Tom White to unravel the mystery. Together with the Osage he and his undercover team began to expose one of the most chilling conspiracies in American history.
