In Code Breaking , Rudolf Kippenhahn offers readers both an exciting chronicle of cryptography and a lively exploration of the cryptographer’s craft. Rich with vivid anecdotes from a history of coding and decoding and featuring three new chapters, this revised and expanded edition makes the often abstruse art of deciphering coded messages accessible to the general reader and reveals the relevance of codes to our everyday high-tech society. A stylishly written, meticulously researched adventure, Code Breaking explores the ways in which communication can be obscured and, like magic, made clear again.

    Yardley was chief of the first peacetime cryptanalytic organization in the United States, the ancestor of today's National Security Agency. Funded by the U.S. Army and the Department of State and working out of New York, his small and highly secret unit succeeded in breaking the diplomatic codes of several nations, including Japan. The decrypts played a critical role in U.S. diplomacy. Despite its extraordinary successes, the Black Chamber, as it came to known, was disbanded in 1929. President Hoover's new Secretary of State Henry L. Stimson refused to continue its funding with the now-famous comment, Gentlemen do not read other people's mail. In 1931 a disappointed Yardley caused a sensation when he published this book and revealed to the world exactly what his agency had done with the secret and illegal cooperation of nearly the entire American cable industry. These revelations and Yardley's right to publish them set into motion a conflict that continues to this day: the right to freedom of expression versus national security. In addition to offering an expos� on post-World War I cryptology, the book is filled with exciting stories and personalities.

    Known to her coworkers as the Queen of Cuba, she was an overachiever who advanced quickly through the ranks of Latin American specialists to become the intelligence community's top analyst on Cuban affairs. But throughout her sixteen-year career at DIA, Montes was sending Castro some of America's most closely guarded secrets and at the same time helping influence what the United States thought it knew about Cuba. When she was finally arrested in September 2001, she became the most senior American intelligence official ever accused of operating as a Cuban spy from within the federal U.S. government. Unrepentant as she serves out her time in a federal prison in Texas, Montes remains the only member of the intelligence community ever convicted of espionage on behalf of the Cuban government.This inside account of the investigation that led to her arrest has been written by Scott W. Carmichael, the DIA's senior counterintelligence investigator who persuaded the FBI to launch an investigation. Although Montes did not fit the FBI's profile of a spy and easily managed to defeat the agency's polygraph exams, Carmichael became suspicious of her activities and with the FBI over a period of several years developed a solid case against her. Here he tells the story of that long and ultimately successful spy hunt. Carmichael reveals the details of their efforts to bring her to justice, offering readers a front-row seat for the first major U.S. espionage case of the twentieth century. She was arrested less than twenty-four hours before learning details of the U.S. plan to invade Afghanistan post-September 11. Motivated by ideology not money, Montes was one of the last true believers of the communist era. Because her arrest came just ten days after 9/11, it went largely unnoticed by the American public. This book calls attention to the grave damage Montes inflicted on U.S. security--Carmichael even implicates her in the death of a Green Beret fighting Cuban-backed insurgents in El Salvador--and the damage she would have continued to inflict had she not been caught.

    From the Purple Machine to the Navajo Talkers to the breaking of Japan's JN-25 Naval Code to the shadowy world of decoding units like Hut-8 in Bletchley Park, he shows how crucial information-often obtained by surreptitious and violent means-was the decisive edge in the Battle of Britain, at Midway and against the U-Boats in the North Atlantic, and how Allied intelligence saved the Soviet Union from almost certain defeat. In an accessible account based on years of research, interviews and exclusive access to previously top-secret archives, Haufler demonstrates how cryptography enabled Nimitz and MacArthur to persevere in the Pacific and helped Eisenhower and Patton mount the assaults on Normandy. In compelling detail, Haufler shows us how it was done-as only one who was on the frontlines of the "secret war" could tell it.

    

    Its essence is sharing. Therefore, Bill W. and Dr. Bob are always referred to within the Fellowship as the co-founders. So far, among the majority of A.A. members, the Ohio surgeon has been less well known than his partner. He died in 1950, when A.A. was only 15 years old. But his influence on the whole A.A. program is permanent and profound. This book gives a portrait of Dr. Bob as full-sale and balanced as possible—for the most part, in the words of those who knew him personally. The young man who grew up in Vermont became a hard-drinking college boy, then a medical student fighting the onset of his own alcoholism, a respected physician, a loving but increasingly unreliable family man, and at last a desperately ill drunk. He was without hope until he met a stockbroker from New York—Bill W., who urgently needed a fellow alcoholic to help him maintain his own sobriety. His story then becomes inextricably entwined with that of Alcoholics Anonymous: from a fledgling Fellowship to a powerful spiritual movement with a worldwide reach. Dr. Bob’s story remains instructional and inspiring to those who read it today.

    There’s Killer of the Cloth, The Baby in the Convent, Mosquito Point Road, Death of a First Baseman, The Blue Gardenia, and Pure/Evil. Three of the killers are female.

    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, including "the White Rabbit" and Violette Szabo. 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. Writing with the narrative flair and vivid characterization of his famous screenplays, Marks gives free rein to his keen sense of the absurd and his wry wit, resulting in a thrilling and poignant memoir that celebrates individual courage and endeavor, without losing sight of the human cost and horror of war.

    From working with a double agent who betrays his friendship and exposes a top secret cross border operation, Terry McIntosh wrestles with his own doubts and fears while protecting the rights of others to live free. He was chosen from the ranks of long range reconnaissance training to serve with Special Forces Detachment A-team 414 in the Mekong Delta, Vietnam 1968-1969. The border camp conducted clandestine operations to observe and engage a growing Viet Cong armed force 15 miles across the line. The top secret mission is exposed after team members are accused of executing the double agent. It is believed that Terry McIntosh is the youngest soldier to serve with the Green Berets on an "A" team and earn the coveted Combat Badge. This is his story about the transition from boy to man in the jungles of Vietnam where he met himself for the first time with a sense of shame and honor.

    His courage was remarkable, as was the way he defied his handicap. The film Reach for the Sky brought Bader’s life into cinemas, and Robert Jackson's classic biography was the first to document his life. After a lonely childhood Bader’s early reputation as a sportsman and a daredevil made him popular with his contemporaries. But he was also an irritation to his superiors, a pattern which continued throughout his life, and hid an academic ability which won him a scholarship to St Edward’s School and a cadetship at the elite RAF College in Cranwell. After his accident, Bader was determined to rejoin the RAF. As a pilot, he was an tactical innovator, a man who confronted the methods of other pilots. When he was a Prisoner of War, Bader’s antagonism toward his guards, and his political pronouncements in later life, sometimes provoked his colleagues, but never lost him their lasting respect and admiration. After retiring from the RAF he combined a full-time job with Shell with all the demands of being a celebrity; his inspiration to the disabled gained him many accolades and finally a knighthood.Both aggressive and charming, Bader’s outward personality was famous. Robert Jackson describes the evolution of that forceful character, and the motivation behind his remarkable achievements. ‘Its style and structure make it readily accessible and, like your favourite armchair, it is easy to relax into at the end of a busy day.’ Frank BurnsRobert Jackson has been a full-time author since 1969, specializing in aviation and military history. A retired member of the Royal Air Force Volunteer Reserve, he has flown a wide variety of aircraft, ranging from jets to gliders.

    Richard Coles, led a pilgrimage to all the major historic sites of the Holy Land: from Nazareth and the Sea of Galilee in the North, via Jericho and the Jordan River, to Bethlehem and, finally, Jerusalem. All of the pilgrims in his care were practising Christians, except one: the writer Kevin Jackson, a diffident and sympathetic atheist intrigued by the chance to take part in this modern-day version of an ancient act of piety, and to learn some more about his old friend, the media clergyman.Coles to Jerusalem is Kevin Jackson’s light-hearted diary of that pilgrimage, and a close-up portrait of Richard Coles both as priest and as man. As the journey proceeds, Coles reminisces at length about his past life as a rock star and radical gay agitator, his new life as a spiritual leader and a popular broadcaster on BBC radio and television, and the strange, unpredictable path that led him from self-destructive debauchery to faith and vocation.With a lively supporting cast of fellow pilgrims, Coles to Jerusalem ranges among the magnificence of ancient monuments and the banalities of the guided tour, the grim political background of contemporary Israel and the comedy of a group of idiosyncratic English folk abroad, the intensity of worship and the lightness of banter. It will be irresistible to all admirers of Richard Coles, who has contributed a foreword; and a revelation to those who have never encountered his wisdom and warmth.

     Geneva Snow commits the unforgivable Southern sin. No longer the apple of her father’s eye, she is a pariah, defying her society's most sacrosanct rule. To protect her—and hoping for a change of heart—her shattered yet steadfast father hides her at Cairnaerie, his mountain estate. But his iron-willed daughter is unrepentant. After years of solitude, an older and wiser Geneva is finally mellowing, and she is desperate to leave a legacy worthy of the father she loved and lost. To that end, she engages an unwitting young history professor for help to escape Cairnaerie long enough to attend the wedding of her granddaughter—a girl dangerously unaware of her lineage. But when a postman’s malevolence and a colleague’s revenge converge, Geneva's long-kept secret is exposed. For a second time, she faces a calamity of her own making. Only this time, there is no place to hide.

    But there is one other crucial factor, which is much less well known. The same team had done it before. The truth is that many of those most closely involved in cracking the Enigma code – Alistair Denniston, Frank Birch, Dilly Knox – had wrestled with German naval codes for most of the First World War. By the end of the war they had been successfully cracking a new code every day, from their secret Room 40 at the Old Admiralty Building, in a London blacked out for Zeppelin Raids.The techniques they developed then, the ideas that they came to rely on, the people they came to trust, had been developed the hard way, under intense pressure and absolute secrecy during World War I. Before Enigma tells their story and explains how they managed to crack the supposedly indecipherable code. The book outlines the capture of the Magdeburg and the Hobart, discusses the use of cracked codes to bring German fleets to battle at Dogger Bank and Jutland, and focuses on individuals such as Winston Churchill and Admiral Sir Reginald ‘Blinker’ Hall and their importance in the development of a British naval code tradition.
