"'You are to report to Station X at Bletchley Park, Buckinghamshire, in four days time . . . That is all you need to know.' This was the terse telegram hundreds of young women throughout the British Isles received in the spring of 1941, as World War II raged. As they arrived at Station X, a sprawling mansion in a state of disrepair surrounded by Spartan-looking huts with little chimneys coughing out thick smoke--these young people had no idea what kind of work they were stepping into. Who had recommended them? Why had they been chosen? Most would never learn all the answers to these questions. Bletchley Park was a well-kept secret during World War II, operating under the code name Station X. The critical work of code-cracking Nazi missives that went on behind its closed doors could determine a victory or loss against Hitler's army. Amidst the brilliant cryptographers, flamboyant debutantes, and absent-minded professors working there, it was teenaged girls who kept Station X running. Some could do advanced math, while others spoke a second language. They ran the unwieldy bombe machines, made sense of wireless sound waves, and sorted the decoded messages. They were expected to excel in their fields and most importantly: know how to keep a secret"--Provided by publisher.

"One of the founders of United States cryptology who would eventually become one of the world's greatest code breakers, Elizebeth Smith Friedman (1892-1980) was a brilliant mind behind many important battles throughout the twentieth-century, saving many lives through her intelligence and heroism. Whip-smart and determined, Elizebeth displayed a remarkable aptitude for language and recognizing patterns from a young age. After getting her start by looking for linguistic clues to the true authorship of Shakespeare's writings, she and her husband William Friedman were tasked with heading up the first government code-breaking unit in America, training teams and building their own sophisticated code systems during the lead-up to World War I. Elizebeth's solo career was even more impressive. She became the Treasury Department's and Coast Guard's first female codebreaker and created her own top-notch codebreaking unit, where she trained and led many male colleagues. During Prohibition of the 1920's, her work solving and intercepting coded messages from mobsters and criminal gangs lead to hundreds of high-profile criminal prosecutions, including members of Al Capone's gang. Her crowning achievement came during World War II, when Elizbeth uncovered an intricate network of Nazi spies operating in South America, a feat that neither law enforcement nor intelligence agencies had been able to accomplish. Despite her unparalleled accomplishments, she was largely written out of history books and overshadowed by her husband"--Provided by publisher.

"An inspiring graphic novel about Elizebeth Friedman, a codebreaking pioneer who changed the course of World War II. Nazi spy rings! No-good gangsters! Shakespearian lies! Discover the courageous woman who cracked all these cases and more-with only a pencil and paper. The youngest of ten siblings, Elizebeth Friedman stood out from an early age with brilliant language skills and a passion for English literature. Eventually, these talents led to a new opportunity: codebreaking. Using ciphers and other trailblazing techniques, Friedman solved coded messages to take down some of the most notorious gangsters in the United States, including the infamous Al Capone. During World War II, as German forces stormed across Europe, she took her skills to the frontlines, thwarting Nazi spies and helping lead Allied forces to victory. In this action-packed, full-color graphic novel, learn more about this daring woman who took risks, defied expectations, and confronted the enemies of World War II"--.

"A nonfiction manuscript for young readers about a group of Allied spies and codebreakers that cracked the Nazis's infamous cypher, allowing them to read secret military messages and turn the tide of World War II"--Provided by publisher.
