We spoke with David Grann, author of non-fiction page-turners including The Lost City of Z: A Tale of Deadly Obsession in the Amazon and Killers of the Flower Moon: The Osage Murders and the Birth of the FBI, to say nothing of his many incredible articles about crime and adventure that he’s written over the past twenty years for The New Yorker. And he has a new book, The Wager: A Tale of Shipwreck, Mutiny and Murder. It’s about seafaring, nautical battles, castaways on the brink of starvation, but it’s also about the very fabric of society.
