Setting

Set in the 1920s, Killers of the Flower Moon unfolds against the backdrop of a rapidly changing America. The Roaring Twenties brought unprecedented wealth and modernization but also exposed deep-seated tensions and inequalities. This era of prosperity and social upheaval provides the backdrop for the book’s tragic events.

The story primarily takes place in Osage County, Oklahoma, a vast expanse of rolling prairie in the northeastern part of the state. Once a reservation, this land became home to some of the wealthiest people per capita in the world after oil was discovered beneath its surface. Author David Grann vividly describes the stark contrast between the opulent lifestyles of the Osage and the surrounding rural poverty.

Within this broader setting, Grann focuses on specific locations that play crucial roles in the narrative. The town of Fairfax serves as a central hub for many of the events, while the nearby city of Pawhuska, the Osage Nation's capital, also features prominently. The author's meticulous research brings to life the dusty streets, oil derricks, and grand mansions that defined this unique time and place in American history.

Key Figures

• William King Hale: The mastermind behind the Osage murder conspiracy. Hale was a prominent cattleman and businessman who orchestrated a complex plot to gain control of Osage oil wealth through manipulation and murder.

Hale's actions epitomized the greed and racism that fueled the systematic exploitation of the Osage people.

White assembled an undercover team and employed innovative investigative techniques to unravel the conspiracy.
