In the background of almost every piece of footage in Britain's great wartime leader Winston Churchill, is an anonymous figure: his bodyguard, Detective Inspector Walter Thompson of Scotland Yard. This is the story of how these two very different characters met, and how the poor boy from London's East End saved his boss from an IRA assassination attempt. In almost any piece of film you'll see of Britain's great wartime leader, he is the man in the background, anonymous and secret. Until now, his critical role in saving the life of Churchill from a series of attacks has been hidden from the wider public. After the war Walter Thompson's censored book told just part of the story. His full memoirs were suppressed even by Churchill himself. Only now can we recount the number of assassination attempts on Churchill's life, many foiled by Walter. This thirteen part series, with unique access to these incredible memoirs, reveals for the first time the story of Walter's life with Winston. Together they travelled thousands of miles on precarious journeys to meet Stalin and Roosevelt and other world leaders. Together they rode with Lawrence of Arabia, dodged German assassins, were nearly shot down by enemy aircraft, lone gunmen, U-boats and IRA hitmen.
