One of the most colorful and controversial figures in American intelligence, Herbert O. Yardley (1889-1958) gave America its best form of information, but his fame rests more on his indiscretions than on his achievements. In this highly readable biography, a premier historian of military intelligence tells Yardley's story and evaluates his impact on the American intelligence community. Yardley established the nation's first codebreaking agency in 1917, and his solutions helped the United States win a major diplomatic victory at the 1921 disarmament conference. But when his unit was closed in 1929 because "gentlemen do not read each other's mail," Yardley wrote a best-selling memoir that introduced-and disclosed-codemaking and codebreaking to the public. David Kahn de-scribes the vicissitudes of Yardley's career, including his work in China and Canada, offers a capsule history of American intelligence up to World War I, and gives a short course in classical codes and ciphers. He debunks the accusations that the publication of Yardley's book caused Japan to change its codes and ciphers and that Yardley traitorously sold his solutions to Japan. And he asserts that Yardley's disclosures not only did not hurt but actually helped American codebreaking during World War II.

From James McManus, author of the bestselling Positively Fifth Street, comes the definitive story of the game that, more than any other, reflects who we are and how we operate. Cowboys Full is the story of poker, from its roots in China, the Middle East, and Europe to its ascent as a global—but especially an American—phenomenon. It describes how early Americans took a French parlor game and, with a few extra cards and an entrepreneurial spirit, turned it into a national craze by the time of the Civil War. From the kitchen-table games of ordinary citizens to its influence on generals and diplomats, poker has gone hand in hand with our national experience. Presidents from Abraham Lincoln to Barack Obama have deployed poker and its strategies to explain policy, to relax with friends, to negotiate treaties and crises, and as a political networking tool. The ways we all do battle and business are echoed by poker tactics: cheating and thwarting cheaters, leveraging uncertainty, bluffing and sussing out bluffers, managing risk and reward. Cowboys Full shows how what was once accurately called the cheater's game has become amostly honest contest of cunning, mathematical precision, and luck. It explains how poker, formerly dominated by cardsharps, is now the most popular card game in Europe, East Asia, Australia, South America, and cyberspace, as well as on television. It combines colorful history with firsthand experience from today's professional tour. And it examines poker's remarkable hold on American culture, from paintings by Frederic Remington to countless poker novels, movies, and plays. Braiding the thrill of individual hands with new ways of seeing poker's relevance to our military, diplomatic, business, and personal affairs, Cowboys Full is sure to become the classic account of America's favorite pastime.

Much has been written about U.S. intelligence operations. However, intelligence, as it is conducted in the U.S. domestic environment, has usually been treated in a fractured and sensationalistic manner. This book dispassionately assesses the U.S. domestically oriented intelligence enterprise by first examining its individual components and then sho

During the 1920s Herbert O. 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 exposé on post-World War I cryptology, the book is filled with exciting stories and personalities.
