““Soon after joining the agency, Marks set out to lessen the danger. His first step was to get rid of the codes that the agency had been using to communicate with its people in the field. They had come from MI6, which, for the first two years of SOE’s existence, had controlled its wireless circuits and provided its sets and coding. Marks was dismayed by the simplicity of the codes, which were based on classic English poems by Shakespeare and others that were “so familiar that an educated German was quite capable of recognizing them and guessing the cipher.” To replace them, he wrote poems of his own, ranging from ribald verses to tender love poems. He gave one of the latter, entitled “The Life That I Have,” to a twenty-one-year-old agent named Violette Szabo, who, after being parachuted into France in 1942, was eventually captured, tortured, and killed by the Gestapo. It read: The life that I have Is all that I have And the life that I have Is yours. The love that I have Of the life that I have Is yours and yours and yours. A sleep I shall have A rest I shall have Yet death will be but a pause For the peace of my years In the long green grass Will be yours and yours and yours. Since then, the poem has developed a life of its own. It has been used in a movie about Szabo’s life, found in poetry anthologies, reprinted on a 9/11 victims’ website, and recited by Chelsea Clinton and Marc Mezvinsky at their wedding in 2010. “Every code,” Marks would later say, “has a human face.””
