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.

“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...

'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.

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 story of Bletchley Park's codebreaking operations in the Second World War is now well known, but its counterparts in the First World War – Room 40 & MI1(b) – remain in the shadows, despite their involvement in and influence on most of the major events of that war. From the First Battle of the Marne, the shelling of Scarborough, the battles of Jutland and the Somme in 1916, to the battles on the Western Front in 1918, the German naval mutiny and the Zimmermann Telegram, this cast of characters – several of them as eccentric as anyone from Bletchley Park in the Second World War – secretly guided the outcome of the 'Great War' from the confines of a few smoke-filled rooms. Using hundreds of intercepted and decrypted German military, naval and diplomatic messages, bestselling author Paul Gannon reveals the fascinating story of British codebreaking operations. By drawing on many newly discovered archival documents that challenge misleading stories about Room 40 & MI1(b), he reveals a sophisticated machine in operation.

A British officer recounts his harrowing years as a POW in Thailand, including his time as the camp commandant, in this WWII memoir. Colonel Cary Owtram served with the 137th Field Regiment, Royal Artillery, and the 11th Indian Infantry Division in Malaysia. After being captured by the Japanese in Singapore, he was transported to the infamous Burma railway. He went on to spend the next three and a half years in grueling captivity in Thailand, first in Ban Pong Camp and then Chungkai Camp—one of the largest POW camps in the region. Owtram was appointed the British Camp Commandant at Chungkai, making him responsible for his fellow prisoners—a heavy responsibility added to the general deprivation and hardship suffered by all. During that time, Owtram kept a secret diary in which he recorded the brutal experience of surviving day to day and attempting to deal with their harsh and unpredictable Japanese captors. It is not only the prisoners who suffered, but also their families at home. The postscript by Owtram’s daughters vividly demonstrates the agonies of doubt and worry that loved ones went through and the effect of the experience on all.

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.

Decoded tells the story of Rong Jinzhwen, one of the great code-breakers in the world. A semi-autistic mathematical genius, Jinzhen is recruited to the cryptography department of China's secret services, Unit 701, where he is assigned the task of breaking the elusive 'Code Purple'. Jinzhen rises through the ranks to eventually become China's greatest and most celebrated code-breaker; until he makes a mistake. Then begins his descent through the unfathomable darkness of the world of cryptology into madness. Decoded was an immediate success when it was published in 2002 in China and has become an international bestseller. With the pacing of a literary crime thriller, Mai Jia's masterpiece also combines elements of historical fiction and state espionage. Taking place in the shadowy world of Chinese secret security, where Mai Jia worked for decades, it introduces us to a place that is unfamiliar, intriguing and authentic. And with Rong Jinzhen, it introduces us to a character who is deeply flawed and fragile, yet possessing exceptional intelligence. Decoded is an unforgettable and gripping story of genius, brilliance, insanity and human frailty. Mai Jia (the pseudonym of Jiang Benhu) is arguably the most successful writer in China today. His books are constant bestsellers, with total sales over three million copies. He became the highest paid author in China last year with his new book, Wind Talk. He has achieved unprecedented success with film adaptation: all of his novels are made - or are being made - into major films or TV series, the screenplays of which are often written by Mai Jia himself. He is hailed as the forerunner of Chinese espionage fiction, and has created a unique genre that combines spycraft, code-breaking, crime, human drama, historical fiction, and metafiction. He has won almost every major award in China, including the highest literary honor - the Mao Dun Award.
