Thurber House presents an event with New Yorker staff writer David Grann. His new book, Killers of the Flower Moon: The Osage Murders and the Birth of the FBI, is a haunting true-life murder mystery about one of the most monstrous crimes in American history. Members of the Osage Indian nation struck it rich after oil was discovered beneath their land in the 1920s. Then, the Osage began to be murdered. Based on years of research, the book is a masterpiece of narrative nonfiction. Tickets are $25, or $20 for students and seniors. All tickets are $25 at the door. The reading and Q&A will last about an hour, with a book signing and a punch and cookies reception to follow.
