Spring 1940: The Battle of the Atlantic rages. Vulnerable merchant convoys are at the mercy of German U-boats controlled by a cunning system of coded messages created by a machine called Enigma. Only one man believes that these codes can be broken - mathematician and Bletchley Park cryptanalyst Alan Turing. Winston Churchill later described Turing's success in breaking the Enigma codes as the single biggest contribution to victory against Nazi Germany. Unheralded during his lifetime, Turing is now recognized as the father of modern computer science and as possessing one of the greatest minds of the 20th century. Drawing on original source material, interviews and photographs, this book explores Turing's groundbreaking work as well as revealing the private side of a complex and unlikely national hero.

The highly eccentric Alfred Dillwyn Knox, known simply as 'Dilly', was one of the leading figures in the British codebreaking successes of the two world wars. During the first, he was the chief codebreaker in the Admiralty, breaking the German Navy's main flag code, before going on to crack the German Enigma ciphers during the Second World War at Bletchley Park. Here, he enjoyed the triumphant culmination of his life's work: a reconstruction of the Enigma machine used by the Abwehr, the German Secret Service. This kept the British fully aware of what the German commanders knew about Allied plans, allowing MI5 and MI6 to use captured German spies to feed false information back to the Nazi spymasters. Mavis Batey was one of 'Dilly's girls', the young female codebreakers who helped him to break the various Enigma ciphers. She was called upon to advise Kate Winslet, star of the film Enigma, on what it was like to be one of the few female codebreakers at Bletchley Park. This gripping new edition of Batey's critically acclaimed book reveals the vital part Dilly played in the deception operation that ensured the success of the D-Day landings, altering the course of the Second World War.

A fatal blend of revenge and desire. After leaving her fiancé at the altar and quitting her job as a Miami cop, Beau Hayley stumbles through life, feeling only resentment. Injustice. Loss. Her mom's death was called an accident. She's not convinced. Grieving, she becomes numb to everything except the constant, biting pain of heartbreak and hate. She can see no light.

A complete mystery. And impossible to resist. James Kelly has only one objective. Find the men who murdered his family and kill them all very slowly. But the web of crime and deceit leads him to Beau Hayley, the daughter of the notorious detective who pursued him relentlessly until her death. Beau is not what James expected, and past the darkness that shrouds her, he finds a glimmer of light. Light is addictive. An escape.

Still The Enigma Two tortured souls playing one deadly game. But who will survive?

A NEW YORK TIMES BESTSELLER The official book behind the Academy Award-winning film The Imitation Game, starring Benedict Cumberbatch and Keira Knightley It is only a slight exaggeration to say that the British mathematician Alan Turing (1912–1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades—all before his suicide at age forty-one. This New York Times bestselling biography of the founder of computer science, with a new preface by the author that addresses Turing’s royal pardon in 2013, is the definitive account of an extraordinary mind and life. Capturing both the inner and outer drama of Turing’s life, Andrew Hodges tells how Turing’s revolutionary idea of 1936—the concept of a universal machine—laid the foundation for the modern computer and how Turing brought the idea to practical realization in 1945 with his electronic design. The book also tells how this work was directly related to Turing’s leading role in breaking the German Enigma ciphers during World War II, a scientific triumph that was critical to Allied victory in the Atlantic. At the same time, this is the tragic account of a man who, despite his wartime service, was eventually arrested, stripped of his security clearance, and forced to undergo a humiliating treatment program—all for trying to live honestly in a society that defined homosexuality as a crime. The inspiration for a major motion picture starring Benedict Cumberbatch and Keira Knightley, Alan Turing: The Enigma is a gripping story of mathematics, computers, cryptography, and homosexual persecution.

From André Aciman, the author of Call Me by Your Name (now a major motion picture and the winner of the OscarTM for Best Adapted Screenplay) comes “a sensory masterclass, absorbing, intelligent, unforgettable” (Times Literary Supplement). André Aciman, hailed as a writer of “fiction at its most supremely interesting” (The New York Review of Books), has written a novel that charts the life of a man named Paul, whose loves remain as consuming and as covetous throughout his adulthood as they were in his adolescence. Whether the setting is southern Italy, where as a boy he has a crush on his parents’ cabinetmaker, or a snowbound campus in New England, where his enduring passion for a girl he’ll meet again and again over the years is punctuated by anonymous encounters with men; whether he’s on a tennis court in Central Park, or on a New York sidewalk in early spring, his attachments are ungraspable, transient, and forever underwritten by raw desire—not for just one person’s body but, inevitably, for someone else’s as well. In Enigma Variations, Aciman maps the most inscrutable corners of passion, proving to be an unsparing reader of the human psyche and a master stylist. With language at once lyrical, bare-knuckled, and unabashedly candid, he casts a sensuous, shimmering light over each facet of desire to probe how we ache, want, and waver, and ultimately how we sometimes falter and let go of those who may want to offer only what we crave from them. Ahead of every step Paul takes, his hopes, denials, fears, and regrets are always ready to lay their traps. Yet the dream of love lingers. We may not always know what we want. We may remain enigmas to ourselves and to others. But sooner or later we discover who we’ve always known we were.
