Paul Dukes, meanwhile, thinking Agar dead because of his failure to appear at their rendezvous point, resolved to leave Petrograd by land and was forced to jump from tram to tram in the city to shake off Cheka agents. After a series of extraordinary adventures through war-torn Latvia under a variety of disguises, he got back to London with his secret documents copied onto tissue paper. He was subsequently knighted by King George V, and remains the only man to be knighted based entirely on his exploits as a spy.
