On this edition of StudioTulsa, we revisit our fascinating 2017 conversation with David Grann, the bestselling author and staff writer at The New Yorker Magazine. At that time, Grann was promoting his then-new book, "Killers of the Flower Moon: The Osage Murders and the Birth of the FBI" (which has been optioned for a much-talked-about film version). Grann will deliver a free-to-the-public Presidential Lecture here at TU on Tuesday the 22nd; his talk begins at 7:30pm in the Reynolds Center. (TU's Presidential Lecture Series is sponsored by the Darcy O'Brien Endowed Chair and supported by the Office of the Provost.) More about Grann's upcoming lecture is posted here.
