On this episode, we were joined by David Grann, author of the The Wager, the gripping story of a doomed 18th-century imperial expedition to South America which culminated in shipwreck, mutiny, and near-impossible survival.

Grann is a New Yorker staff writer and bestselling author of the contemporary non-fiction classics The Lost City Z and Killers of the Flower Moon, now a major motion picture from Martin Scorsese and Leonardo DiCaprio premiering this week at the Cannes Festival.

He spoke to us about piecing together a story from several competing narratives; his love of sea tales and adventure stories; why his books lend themselves so well to the screen; and how stories such as these expose the ugly contradictions at the centre of colonial Europe.

We also hear about his own dangerous boat journey to Wager Island, where no amount of anti-motion sickness medicine could lessen the impact of the storm-wracked seas.
