In The Footsteps Of Scott.
Not strictly a book set in the 'heroic era' but still worth reading. Mear and Swan follow Scott's footsteps and after a superb effort make it to the pole. It's then that a story, worthy of another book, shows the America dominance of the South Pole as a sinister, dominant force. The political fall-out is enlightening and worrying. The book itself tells a great story, it does have gaps but then they were explorers not writers. The book changed its title when it went to America - 'A Walk To The Pole'. Published by Jonathon Cape 1987.
