In the winter of 1911, Captain Robert Falcon Scott and his party set out into the frozen heart of Antarctica. Battling blizzards and treacherous terrain, they were determined to be the first people to reach the South Pole. But when they arrived in early 1912, they discovered that a Norwegian team had beaten them to it. As if that weren't enough, their return journey turned into a tragedy, with Scott and his men dying just 11 miles from a supply depot that would have been their salvation.

Their deaths are usually attributed to Scott's failures in planning and leadership or simple bad luck. But based on rediscovered documents, journalist and writer Harrison Christian points to other, more sinister causes - betrayal, sabotage, and a bubbling animosity that pitted the expedition's two most senior members against one another.

Harrison's book is called 'Terra Nova: Ambition, jealousy and simmering rivalry in the Heroic Age of Antarctic Exploration'.

Produced by James Hickmann and edited by Dougal Patmore.
