During the first half of the 20th century, dozens of murders plagued the oil-rich Osage Nation. The question of who killed them, and why, spread beyond the borders of the nation, eventually being picked up by the fledgling FBI.

In this episode, Don speaks to David Grann, author of the silver-screen adapted 'Killers of the Flower Moon: The Osage Murders and the Birth of the FBI'. Don and David explore the Osage Nation, why it fell victim to the greed of its neighbours, and how the truth was eventually discovered.

Produced by Sophie Gee. Edited by Aidan Lonergan. Senior Producer was Charlotte Long.
