The magnificent, unrivaled history of codes and ciphers -- how they're made, how they're broken, and the many and fascinating roles they've played since the dawn of civilization in war, business, diplomacy, and espionage -- updated with a new chapter on computer cryptography and the Ultra secret. Man has created codes to keep secrets and has broken codes to learn those secrets since the time of the Pharaohs. For 4,000 years, fierce battles have been waged between codemakers and codebreakers, and the story of these battles is civilization's secret history, the hidden account of how wars were won and lost, diplomatic intrigues foiled, business secrets stolen, governments ruined, computers hacked. From the XYZ Affair to the Dreyfus Affair, from the Gallic War to the Persian Gulf, from Druidic runes and the kaballah to outer space, from the Zimmermann telegram to Enigma to the Manhattan Project, codebreaking has shaped the course of human events to an extent beyond any easy reckoning. Once a government monopoly, cryptology today touches everybody. It secures the Internet, keeps e-mail private, maintains the integrity of cash machine transactions, and scrambles TV signals on unpaid-for channels. David Kahn's The Codebreakers takes the measure of what codes and codebreaking have meant in human history in a single comprehensive account, astonishing in its scope and enthralling in its execution. Hailed upon first publication as a book likely to become the definitive work of its kind, The Codebreakers has more than lived up to that prediction: it remains unsurpassed. With a brilliant new chapter that makes use of previously classified documents to bring the book thoroughly up to date, and to explore the myriad ways computer codes and their hackers are changing all of our lives, The Codebreakers is the skeleton key to a thousand thrilling true stories of intrigue, mystery, and adventure. It is a masterpiece of the historian's art.

NEW YORK TIMES BESTSELLER • Turn: Washington’s Spies, now an original series on AMC Based on remarkable new research, acclaimed historian Alexander Rose brings to life the true story of the spy ring that helped America win the Revolutionary War. For the first time, Rose takes us beyond the battlefront and deep into the shadowy underworld of double agents and triple crosses, covert operations and code breaking, and unmasks the courageous, flawed men who inhabited this wilderness of mirrors—including the spymaster at the heart of it all. In the summer of 1778, with the war poised to turn in his favor, General George Washington desperately needed to know where the British would strike next. To that end, he unleashed his secret weapon: an unlikely ring of spies in New York charged with discovering the enemy’s battle plans and military strategy. Washington’s small band included a young Quaker torn between political principle and family loyalty, a swashbuckling sailor addicted to the perils of espionage, a hard-drinking barkeep, a Yale-educated cavalryman and friend of the doomed Nathan Hale, and a peaceful, sickly farmer who begged Washington to let him retire but who always came through in the end. Personally guiding these imperfect everyday heroes was Washington himself. In an era when officers were gentlemen, and gentlemen didn’ t spy, he possessed an extraordinary talent for deception—and proved an adept spymaster. The men he mentored were dubbed the Culper Ring. The British secret service tried to hunt them down, but they escaped by the closest of shaves thanks to their ciphers, dead drops, and invisible ink. Rose’s thrilling narrative tells the unknown story of the Revolution–the murderous intelligence war, gunrunning and kidnapping, defectors and executioners—that has never appeared in the history books. But Washington’s Spies is also a spirited, touching account of friendship and trust, fear and betrayal, amid the dark and silent world of the spy.

This “engrossing study” of invisible ink reveals 2,000 years of scoundrels, heroes and their ingenious methods for concealing messages (Kirkus). In Prisoners, Lovers, and Spies, Kristie Macrakis uncovers the secret history of invisible ink and the ingenious way everything from lemon juice to Gall-nut extract and even certain bodily fluids have been used to conceal and reveal covert communications. From Ancient Rome to the Cold War, spies have been imprisoned or murdered, adultery unmasked, and battles lost because of faulty or intercepted secret messages. Yet, successfully hidden writing has helped save lives, win battles, and ensure privacy—at times changing the course of history. Macrakis combines a storyteller’s sense of drama with a historian’s respect for evidence in this page-turning history of intrigue and espionage, love and war, magic and secrecy. From Ovid’s advice to use milk for illicit love notes, to John Gerard's dramatic escape from the Tower of London aided by orange juice ink messages, to al-Qaeda’s hidden instructions in pornographic movies, this book charts the evolution of secret messages and their impact on history. An appendix includes kitchen chemistry recipes for readers to try out at home.
