When Captain Scott died in 1912 on his way back from the South Pole, his story became a myth embedded in the national imagination. Everyone remembers the doomed Captain Oates's last words: 'I'm just going outside, and I may be some time.' Francis Spufford's celebrated and prize-winning history shows how Scott's death was the culmination of a national enchantment with vast empty spaces, the beauty of untrodden snow, and perilous journeys to the end of the earth.
