1. Codes of Conduct

Peter France presents three films which reflect the extent to which codes of 'honour', allegiance' and 'behaviour' have had their effect on British history. 1: Christopher Andrew examines the demise of duelling 100 years ago. 2: Ian Dear tells the story of the duplicity behind the victories which kept the America's Cup in New York for 130 years. 3: Phillip Knightley shows the process by which British Intelligence secrets have been leaked steadily since the end of the Second World War.
