The book of Shackleton's earlier "Nimrod" Expedition of 1907–1909 was written, based on Shackleton's dictation, by Edward Saunders, a reporter on the "Lyttelton Times" in Christchurch, New Zealand. Saunders was recommended to Shackleton by the Prime Minister of New Zealand, Sir Joseph Ward; he accompanied Shackleton to Britain to work on "The Heart of the Antarctic", which appeared in November 1909. Saunders was again involved in "South", Shackleton working with Saunders in New Zealand and Australia early in 1917. Saunders later wrote, "If I said that any chapter was entirely mine, I should be telling an untruth. My work was complementary to his. I could say that Shackleton had a remarkable gift of literary suggestion..."
