KILLERS OF THE FLOWER MOON

The Osage Murders and the Birth of the FBI

By David Grann

Illustrated. 338 pages. Doubleday. $28.95.

If you taught the artificial brains of supercomputers at IBM Research to write nonfiction prose, and if they got very good at it, they might compose a book like David Grann’s “Killers of the Flower Moon: The Osage Murders and the Birth of the FBI.”

This is not entirely a complaint. Grann’s new book, about how dozens of members of the Osage Indian nation in Oklahoma in the 1920s were shot, poisoned or blown to bits by rapacious whites who coveted the oil under their land, is close to impeccable. It’s confident, fluid in its dynamics, light on its feet.

What it lacks is the soulful, trippy, questing and offhandedly cerebral quality of his last and best-known book, “The Lost City of Z: A Tale of Deadly Obsession in the Amazon” (2009). That volume is deservedly regarded as one of the prize nonfiction specimens of this century.
