The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

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.

“The reigning queen of historical fiction” -- Fiona Davis, New York Times bestselling author of The Lions of Fifth Avenue The New York Times and USA Today bestselling author of The Huntress and The Alice Network returns with another heart-stopping World War II story of three female code breakers at Bletchley Park and the spy they must root out after the war is over. 1940. As England prepares to fight the Nazis, three very different women answer the call to mysterious country estate Bletchley Park, where the best minds in Britain train to break German military codes. Vivacious debutante Osla is the girl who has everything—beauty, wealth, and the dashing Prince Philip of Greece sending her roses—but she burns to prove herself as more than a society girl, and puts her fluent German to use as a translator of decoded enemy secrets. Imperious self-made Mab, product of east-end London poverty, works the legendary codebreaking machines as she conceals old wounds and looks for a socially advantageous husband. Both Osla and Mab are quick to see the potential in local village spinster Beth, whose shyness conceals a brilliant facility with puzzles, and soon Beth spreads her wings as one of the Park’s few female cryptanalysts. But war, loss, and the impossible pressure of secrecy will tear the three apart. 1947. As the royal wedding of Princess Elizabeth and Prince Philip whips post-war Britain into a fever, three friends-turned-enemies are reunited by a mysterious encrypted letter--the key to which lies buried in the long-ago betrayal that destroyed their friendship and left one of them confined to an asylum. A mysterious traitor has emerged from the shadows of their Bletchley Park past, and now Osla, Mab, and Beth must resurrect their old alliance and crack one last code together. But each petal they remove from the rose code brings danger--and their true enemy--closer...

Walter Isaacson’s #1 New York Times bestselling history of our third scientific revolution: CRISPR, gene editing, and the quest to understand the code of life itself, is now adapted for young readers! When Jennifer Doudna was a sixth grader in Hilo, Hawaii, she came home from school one afternoon and found a book on her bed. It was The Double Helix, James Watson’s account of how he and Francis Crick had discovered the structure of DNA, the spiral-staircase molecule that carries the genetic instruction code for all forms of life. This book guided Jennifer Doudna to focus her studies not on DNA, but on what seemed to take a backseat in biochemistry: figuring out the structure of RNA, a closely related molecule that enables the genetic instructions coded in DNA to express themselves. Doudna became an expert in determining the shapes and structures of these RNA molecules—an expertise that led her to develop a revolutionary new technique that could edit human genes. Today gene-editing technologies such as CRISPR are already being used to eliminate simple genetic defects that cause disorders such as Tay-Sachs and sickle cell anemia. For now, however, Jennifer and her team are being deployed against our most immediate threat—the coronavirus—and you have just been given a front row seat to that race.

This book is about Americans not of Japanese ancestry, who served as Japanese language officers in World War II. Covering the period 1940-1945, it describes their selection, training, and service in the Navy and Marine Corps during the war and their contributions to maintenance of good relations between America and Japan thereafter. It argues that their service as “code breakers” and combat interpreters hastened victory and that their cross-cultural experience and linguistic knowledge facilitated the successful dismantling of the Japanese Empire and the peaceful occupation of Japan. The book shows how the war changed relations between the Navy and academia, transformed the lives of these 1200 men and women, and set onetime enemies on course to enduring friendship. Its purpose is twofold: to reveal an exciting and hitherto unknown aspect of the Pacific War and to demonstrate the enduring importance of linguistic and cross-cultural knowledge within America’s armed forces in war and peace alike.The book is meant for the general reader interested in World War II, as well as academic specialists and other persons particularly interested in that conflict. It will also appeal to readers with an interest in America’s intelligence establishment and to those interested in Japan and its relations with the United States. This history tells and exciting and previously unknown story of men and women whose brains and devotion to duty enabled them to learn an extraordinarily difficult language and use it in combat and ashore to hasten Japan’s defeat and transformation from enemy to friend of America.

'Lively...in giving us the daily details of their lives in the women's own voices Dunlop does them and us a fine service' New Statesman 'Dunlop is engaging in her personal approach. Her obvious feminine empathy with the venerable ladies she spoke to gives her book an immediacy and intimacy.' Daily Mail 'An in-depth picture of life in Britain's wartime intelligence centre...The result is fascinating, and is made all the more touching by the developing friendships between Dunlop and her interviewees.' Financial Times The Bletchley Girls weaves together the lives of fifteen women who were all selected to work in Britain's most secret organisation - Bletchley Park. It is their story, told in their voices; Tessa met and talked to 15 veterans, often visiting them several times. Firm friendships were made as their epic journey unfolded on paper. The scale of female involvement in Britain during the Second World War wasn't matched in any other country. From 8 million working women just over 7000 were hand-picked to work at Bletchley Park and its outstations. There had always been girls at the Park but soon they outnumbered the men three to one. A refugee from Belgium, a Scottish debutante, a Jewish 14-year-old, and a factory worker from Northamptonshire - the Bletchley Girls confound stereotypes. But they all have one common bond, the war and their highly confidential part in it. In the middle of the night, hunched over meaningless pieces of paper, tending mind-blowing machines, sitting listening for hours on end, theirs was invariably confusing, monotonous and meticulous work, about which they could not breathe a word. By meeting and talking to these fascinating female secret-keepers who are still alive today, Tessa Dunlop captures their extraordinary journeys into an adult world of war, secrecy, love and loss. Through the voices of the women themselves, this is a portrait of life at Bletchley Park beyond the celebrated code-breakers, it's the story of the girls behind Britain's ability to consistently out-smart the enemy, and an insight into the women they have become.

The GIs called her Joey. Hundreds owed their lives to the tiny Filipina who stashed explosives in spare tires, tracked Japanese troop movements, and smuggled maps of fortifications across enemy lines. As the Battle of Manila raged, Josefina Guerrero walked through gunfire to bandage wounds and close the eyes of the dead. Her valor earned her the Medal of Freedom, but what made her a good spy was also destroying her: leprosy, which so horrified the Japanese they refused to search her. After the war, army chaplains found her in a nightmarish leper colony and fought for the US government to do something it had never done: welcome a foreigner with leprosy. This brought her celebrity, which she used to publicly speak for other sufferers. However, the notoriety haunted her and she sought a way to disappear. Ben Montgomery now brings Guerrero's heroic accomplishments to light.
