An interesting and disturbing story of a reign of terror in the Osage Indian reservation in Oklahoma during the 1920s. Tribe members had been forced to leave their ancestral lands for a barren part of Oklahoma. The area was later discovered to be oil-rich and the Indians had managed to retain mineral rights to the land, so they became wealthy. The area was then flooded with non-Indian con-men, thieves, and murderers at every level of society, including law enforcement and judges and supported by bigotted congressmen and the Bureau of Indian Affairs. There was an at least decade-long series of scores of murders in attempts to obtain the Tribe members' mineral rights. The book is mainly the story of the solution of one group of murders by agents of the brand new Bureau of Investigation headed by the young J. Edgar Hoover. The author has arranged the story so that it reads more or less like a mystery novel.
