This month's read is "Killers of the Flower Moon" by David Grann. In the 1920s, the richest people per capita in the world were members of the Osage Indian nation in Oklahoma. After oil was discovered beneath their land, they rode in chauffeured automobiles, built mansions, and sent their children to study in Europe. Then, one by one, the Osage began to be killed off. David Grann revisits a shocking series of crimes in which dozens of people were murdered in cold blood.
