If you are looking for exciting books in the 1920s, you should keep your eye out for this true crime story about the fascinating case of the Osage murders. After discovering oil on their land, the Osage Indian Nation in Oklahoma were among the richest people in the world. Once the death toll surpasses 24 Osage, the newly created FBI takes up the investigation to expose an alarming conspiracy behind these notorious crimes. At the heart of the story is Mollie Burkhart who's had one sister die of illness, one sister shot and killed, one sister killed in a home explosion, and her mother die all in one year. 

A much-needed but horrifying look at American history, Killers of the Flower Moon details the true story of the systemic killings of Osage Indians for their wealth. Blending with the early days of the FBI, David Grann follows the investigation and the trial where Burkhart's husband is the key witness against his uncle who conspired to funnel all her relatives' oil claims to her before killing her next. To make it even more horrifying, Burkhart's case was not an isolated one and the historical atrocities committed against the Osage Tribe by Oklahoma citizens make it an even more heinous period of our history.
