I heard of this book due to the new movie coming out but had admittedly never heard of this story. If you are also unfamiliar, it involves the killing of Indigenous Americans in the Osage tribe in Oklahoma during the 1920’s. Many of them end up dead, either clearly by homicide or under mysterious circumstances, and the newly formed FBI ends up on the case. This book is not in narrative form - it very much reads like a news article (and it is authored by a reporter) but I found it gripping nonetheless. It’s quite tragic what happened to the Osage and it’s terrible to see how it’s affected so many generations after. Well-researched and painstakingly sited with primary sources, this is the premier account of this tragic time.
