...the strangest, most horrific story that Grann has told ... Grann folds it, neatly, into three hundred pages. But he also makes something much more out of the material—something deep, devastating, and almost unbearably sad. On the one hand, he takes in the entirety of what was done to the Osage and, by extension, to the American Indian. On the other, he paints intimate portraits of men and women who'd murder their husbands, their wives, their own children ... What we're left with are circles of complicity that widen and widen until, terrifyingly, they grow to encompass the reader as well.
...a masterful work of literary journalism crafted with the urgency of a mystery ... Contained within Grann’s mesmerizing storytelling lies something more than a brisk, satisfying read. Killers of the Flower Moon offers up the Osage killings as emblematic of America’s relationship with its indigenous peoples and the 'culture of killing' that has forever marred that tie.
Flower Moon opens with the feel of an Erik Larson book — Devil in the White City, perhaps: an entertaining murder mystery set in the historical context of 100 years ago. But Grann’s book quickly grows darker, and then darker still. It is superbly done — meticulously researched, well-written — but it is hard to be entertained by a story of such unmitigated evil ... Grann digs deep. He spent years on the research, examining FBI files, court testimony, private correspondence, field reports from the Bureau of Indian Affairs, diary entries and scores of other documents. The result is a powerful book — not entertaining, no, but fascinating; an outrageous, devastating read.
