This non-fiction book documents the murders of oil-rich members of the Osage Indian tribe in the early 20th century. No progress is made in arresting the perpetrators until the fledgling Bureau of Investigation under J. Edgar Hoover gets involved. Even then, undercover agents worked at great risk to identify the killers and bring them to justice. The author did extensive research in historical archives and by interviewing descendants of the victims. Yet, the book reads like a novel and presents an interesting, story-like narrative that describes a chilling conspiracy.
