Margaret MacMillan talks to her nephew Dan about her seminal book 'The War That Ended Peace: The Road To 1914'. They discuss the importance of Storytelling to the historian's process, the ways in which political actors at the time viewed the relation between fate and choice, the role that masculine insecurity played in the build up to the war and also examine the construct of and myths surrounding nationalistic feeling in the pre-war years.
