He's the greatest explorer the world has ever known – the first to navigate the fabled North-West Passage, the first to reach the South Pole, the first to the impossible North. But how much do we really know about Roald Amundsen?

More precisely, how much do we want to know? Surely, the tangled heroics of Scott of the Antarctic and of Ernest Shackleton make for more exciting reading than the careful, boring tales of Amundsen? They faced crises with fortitude, didn't they – while he simply, well, succeeded?

That is, perhaps, the point. So join Oswin and Carla on our enthralling season finale as we dissect 'The Hero's Journey' and the 'Action Fallacy' in the company of Professor Martin Gutmann – and find out why we all deserve to know more about Amundsen and his unseen leadership.
