The preserved diary of doomed Antarctic expeditioner Captain Robert Scott is legendary.
Stranded with his shipmates hundreds of kilometres from base camp, Scott's chilling final words - "for god's sake look after our people" has long symbolised courage, and the spirit of British exploration.
But a new book is unearthing a new dimension to the tragedy, with the help of new historic documents, homing in on a dysfunctional relationship between Captain Scott and his second in command, Edward Evans.
Harrison Christian is the author of 'Terra Nova' and joins Emile Donovan.
