In this extensive masterclass on narrative nonfiction, author David Grann discusses the exacting craft behind books like Killers of the Flower Moon and The Wager. For Grann, compelling nonfiction begins not at the typewriter but in historical repositories. He recounts how weeks of combing through disorganized government boxes in an aircraft-hangar-sized archive5:10 yielded unindexed grand jury transcripts that exposed unpunished perpetrators. Before writing a single sentence, Grann compiles massive chapter outlines6:40—sometimes exceeding 200 pages for a 3,000-word chapter—logging every physical mannerism, spoken diction pattern, and architectural layout to faithfully reconstruct scenes.
Selecting a multi-year project requires clearing three strict hurdles: an initial mystery that hooks curiosity, sufficient primary sources to reconstruct the narrative, and a deeper universal theme. While researching 18th-century mutinies, Grann stumbled upon John Byron's teenage journal10:30 from the wrecked HMS Wager. He realized the survivors' desperate court-martial testimonies formed a battle over the truth13:10, transforming a nautical disaster into a modern parable about narrative manipulation and imperial mythmaking.
To bridge the gap between archival text and sensory reality, Grann emphasizes visiting physical landscapes. He embarked on a turbulent winter voyage to remote Wager Island19:00 off Chilean Patagonia, braving terrifying oceanic swells while listening to Moby Dick21:20. That physical exposure illuminated what documents could not: the debilitating cold revealed that the shipwrecked crew suffered from constant chronic hypothermia25:50, dramatically altering how Grann understood their unraveling decision-making.
When translating research onto the page, Grann creates suspense through strict chronological pacing, deliberately stripping out the artificial lens of hindsight44:00. Because real people live in radical uncertainty, readers must experience each choice in real time. Grann actively limits his authorial presence, choosing to vanish entirely from the text50:25 unless personal perspective provides crucial context, as it did in The Lost City of Z.
Finally, Grann underscores the discipline of ruthless editing. Research must remain invisible; readers only care about the emotional payoff on the page. He describes having to cut tens of thousands of words56:50 detailing ship construction after candid feedback from his wife and editor, preserving only the most striking details. Rather than forcing preconceived messages, Grann insists that themes must emerge organically1:22:50 from the documentation, enabling even tiny human gestures—such as a fleeting handshake between bitter rivals1:16:20—to reveal profound truths about human nature.
