Thomas Edward Lawrence first set foot on the hot sands of Arabia in 1909. By 1918 there was a 20,000 price on his head. His journey to this point has long been legend. From his first postings as archaeologist, liaison and map officer, to fighting alongside guerrilla forces during the Arab Revolt. Journeying more than 300 miles through blistering heat to capture Aqaba, to his involvement in peace conferences that decided the future of the Middle East. A legend in his own lifetime, Lawrence's epic story has always been ripe for the retelling - but Ranulph Fiennes is no ordinary biographer.
