I’ve just finished reading David Grann’s book on the murders of the Osage Indians in Oklahoma in the early 20th Century. This is the result of years of research into the murky past of middle America. It’s a tale of racism, greed, corruption and murder. It also tells us about some of the early heroes of the FBI – and the villains.

I found this book gave me an insight into racism today in the USA, and probably in the UK too. I can begin to understand why some people voted for Donald Trump – and Brexit. It’s unsettling because it throws a lighton the nastier side of human nature, the side I’v told myself was long gone.

Read this book and you will never see things in the same way again.
