In 1942, with a black-market chicken tucked under his arm by his mother, Leo Marks left his father's famous bookshop, 84 Charing Cross Road, and went off to fight the war. He was twenty-two. Soon recognized as a cryptographer of genius, he became head of communications at the Special Operations Executive (SOE), where he revolutionized the codemaking techniques of the Allies and trained some of the most famous agents dropped into occupied Europe. As a top codemaker, Marks had a unique perspective on one of the most fascinating and, until now, little-known aspects of the Second World War. This stunning memoir, often funny, always gripping and acutely sensitive to the human cost of each operation, provides a unique inside picture of the extraordinary SOE organization at work and reveals for the first time many unknown truths about the conduct of the war. SOE was created in July 1940 with a mandate from Winston Churchill to "set Europe ablaze." Its main function was to infiltrate agents into enemy-occupied territory to perform acts of sabotage and form secret armies in preparation for D-Day. Marks's ingenious codemaking innovation was to devise and implement a system of random numeric codes printed on silk. Camouflaged as handkerchiefs, underwear, or coat linings, these codes could be destroyed message by message, and therefore could not possibly be remembered by the agents, even under torture. Between Silk and Cyanide chronicles Marks's obsessive quest to improve the security of agents' codes and how this crusade led to his involvement in some of the war's most dramatic and secret operations. Among the astonishing revelations is his account of the code war between SOE and the Germans in Holland. He also reveals for the first time how SOE fooled the Germans into thinking that a secret army was operating in the Fatherland itself, and how and why he broke the code that General de Gaulle insisted be available only to the Free French. By the end of this incredible tale, truly one of the last great World War II memoirs, it is clear why General Eisenhower credited the SOE, particularly its communications department, with shortening the war by three months. From the difficulties of safeguarding the messages that led to the destruction of the atomic weapons plant at Rjukan in Norway to the surveillance of Hitler's long-range missile base at Peenemünde to the true extent of Nazi infiltration of Allied agents, Between Silk and Cyanide sheds light on one of the least-known but most dramatic aspects of the war. Writing with the narrative flair and vivid characterization of his famous screenplays, Marks gives free rein to his keen sense of the absurd and wry wit without ever losing touch with the very human side of the story. His close relationship with "the White Rabbit" and Violette Szabo -- two of the greatest British agents of the war -- and his accounts of the many others he dealt with result in a thrilling and poignant memoir that celebrates individual courage and endeavor, without losing sight of the human cost and horror of war.

Battle of Wits

A million pages of new World War II codebreaking records have been released by the U.S. Army and Navy and the British government over the last five years. Now, Battle of Wits presents the history of the war that these documents reveal. From the Battle of Midway until the last German code was broken in January 1945, this is an astonishing epic of a war that was won not simply by brute strength but also by reading the enemy's intentions. The revelations of Stephen Budiansky's dramatic history include how Britain tried to manipulate the American codebreakers and monopolize German Enigma code communications; the first detailed published explanations of how the Japanese codes were broken; and how the American codebreaking machines worked to crack the Japanese, the German, and even the Russian diplomatic codes. This is the story of the Allied codebreakers puzzling through the most difficult codebreaking problems that ever existed. At the same time, the compelling narrative shows the crucial effect codebreaking had on the battle-fields by explaining the urgency of stopping the wolf pack U-boat attacks in the North Atlantic, the burning desire in the United States to turn the tide of the war after Pearl Harbor, the importance of halting Rommel's tanks in North Africa, and the necessity of ensuring that the Germans believed the Allies' audacious deception and cover plans for D-Day. Budiansky brings to life the unsung code-breaking heroes of this secret war: Joseph J. Rochefort, an intense and driven naval officer who ran the codebreaking operation in "The Dungeon", a dank basement at Pearl Harbor, that effectively won the Battle of Midway; Alan Turing, the eccentric father of the computerage, whose brilliant electromechanical calculators broke the German Enigma machine; and Ian Fleming, whose daredevil espionage schemes to recover codebooks resembled the plots of the 007 novels he later wrote. Among the villains, we meet the Nazi Admiral Donitz, who led the submarine wolf packs against Allied shipping in the North Atlantic with horrific casualty rates -- until the codebreakers stopped him. Budiansky, a Harvard-trained mathematician, demonstrates the mathematical insight and creativity of the cryptographers by showing step-by-step precisely how the codes were broken. This technology -- the flow of information, its encryption, and the computational methods of recovering it from the enemy -- had never before been so important to the outcome of a war. Informative diagrams, maps, appendices, and photographs show exactly how, why, and where the secret war was won. Unveiled for the first time, the complete story of codebreaking in World War II has now been told.

NEW YORK TIMES BESTSELLER From one of the foremost historians of the period and the acclaimed author of Inferno and Catastrophe: 1914, The Secret War is a sweeping examination of one of the most important yet underexplored aspects of World War II—intelligence—showing how espionage successes and failures by the United States, Britain, Russia, Germany, and Japan influenced the course of the war and its final outcome. Spies, codes, and guerrillas played unprecedentedly critical roles in the Second World War, exploited by every nation in the struggle to gain secret knowledge of its foes, and to sow havoc behind the fronts. In The Secret War, Max Hastings presents a worldwide cast of characters and some extraordinary sagas of intelligence and resistance, to create a new perspective on the greatest conflict in history
