American history is loaded with episodes of shame. A large percentage of our less memorable moments, as a nation, have been swept under the rug, kept out of classrooms, and largely forgotten as time progresses. But these events are real and all it takes is a skilled author to bring the lost history back to life. Such is the case with Killers of the Flower Moon.I did not know anything about these murders against the Osage until I read this book, so this was a definite eye- opener for me. I had heard of the Osage tribe, yes, but I did not know they fell into tremendous oil wealth and, subsequently, saw their members slowly dying off, either through gunfire or poisoning, as greedy individuals tried to get their hands on some easy cash. The book details several of the known killings and the cold, callous, calculated murders are chilling and puzzling. Chilling, because of the gruesomeness of the murders; puzzling, because of the nonchalant behavior of those who plotted the killings. Even when confronted with the murders, most of the guilty individuals seem to have no remorse at all. They don’t even perceive what they did as immoral in any way.This book reads like a mystery thriller, however it isn’t a page- turner, like some mystery genre books. You do start to make guesses as to who is responsible, but rather than get wound up in the who- done- it, the book grips you more for its educational aspects. You learn all sorts of things about the Oklahoma region that the Osage called home. You learn about the newly formed FBI and its role in solving the mystery. You learn about the problems of racism and the feelings of superiority that people felt against Indians. And you learn just how evil people can be when vast amounts of wealth are at stake.There are several surprises in this book, and one is the book’s final section. The book leads you to believe that the mystery has been solved and it sounds like everything is coming to a close. Then suddenly, the book continues for dozens more pages as the author tries to solve more of the mystery on his own, with the aid of local Osage tribe members. No one will ever know exactly how many people were killed during this reign of terror but I like how the author took it on himself to investigate and try to answer more questions.This book is another solid, educational wakeup call on the prevalence of racism and superiority that pervaded society in the past and is rearing its ugly head once again today. I like how the book includes pictures so that you can get to know the many characters involved. With so many names and so many people involved, it’s easy to lose track of who is who. The pictures help you put a face with the name. But the most important part of this book is its educational value. It’s another sad, shameful episode from America’s past and one that we all need to know about and, hopefully, learn from.
