By June 1940, Britain was facing Nazi invasion. Prime Minister Winston Churchill's bodyguard Walter Thompson had at least managed to keep him safe during several dangerous trips to France. But the next year was to bring a host of new perils. For as the bombs rained down, the one person to whose safety Winston gave no thought, was himself, and Walter had to cope as best he could. 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 Churchills 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.
