"Edward Snowden chose three journalists to tell the stories in his Top Secret trove of NSA documents: Barton Gellman of The Washington Post, Glenn Greenwald of The Guardian and filmmaker Laura Poitras, all of whom would share the Pulitzer Prize for Public Service. Poitras went on to direct the Oscar-winning Citizenfour. Greenwald wrote an instant memoir and cast himself as a pugilist on Snowden's behalf. Gellman took his own path. Snowden and his documents were the beginning, not the end, of a story he had prepared his whole life to tell. More than 20 years as a top investigative journalist armed him with deep sources in national security and high technology. New sources reached out from government and industry, making contact on the same kinds of secret, anonymous channels that Snowden had used. Gellman's reporting unlocked new puzzles in the NSA archive. And as Snowden's revelations faded somewhat from the public consciousness, the machinations he exposed continue still, with many policies unaltered despite societal outrage. Dark Mirror is a true-life spy tale that touches us all, told with authority and an inside view of extraordinary events. Within it is a chilling personal account of the obstacles facing the author, beginning with Gellman's discovery of his own name in Snowden's NSA document trove. Google notifies him that a foreign government is trying to compromise his account. A trusted technical adviser finds anomalies on his laptop. Sophisticated impostors approach Gellman with counterfeit documents, attempting to divert or discredit his work. Throughout Dark Mirror, the author wages an escalating battle against unknown digital adversaries who force him to mimic their tradecraft in self-defense. With the vivid and insightful style that marked Gellman's bestselling Angler, Dark Mirror is an inside account of the surveillance-industrial revolution and its discontents, fighting back against state and corporate intrusions into our most private spheres. Along the way, and with the benefit of hindsight, it tells the full story of a government leak unrivaled in drama since All the President's Men"--

Spies, secret messages, and military intelligence have fascinated readers for centuries but never more than today, when terrorists threaten America and society depends so heavily on communications. Much of what was known about communications intelligence came first from David Kahn's pathbreaking book, The Codebreakers. Kahn, considered the dean of intelligence historians, is also the author of Hitler’s Spies: German Military Intelligence in World War II and Seizing the Enigma: The Race to Break the German U-Boat Codes, 1939-1943, among other books and articles. Kahn’s latest book, How I Discovered World War II's Greatest Spy and Other Stories of Intelligence and Code, provides insights into the dark realm of intelligence and code that will fascinate cryptologists, intelligence personnel, and the millions interested in military history, espionage, and global affairs. It opens with Kahn telling how he discovered the identity of the man who sold key information about Germany’s Enigma machine during World War II that enabled Polish and then British codebreakers to read secret messages. Next Kahn addresses the question often asked about Pearl Harbor: since we were breaking Japan’s codes, did President Roosevelt know that Japan was going to attack and let it happen to bring a reluctant nation into the war? Kahn looks into why Nazi Germany’s totalitarian intelligence was so poor, offers a theory of intelligence, explicates what Clausewitz said about intelligence, tells—on the basis of an interview with a head of Soviet codebreaking—something about Soviet Comint in the Cold War, and reveals how the Allies suppressed the second greatest secret of WWII. Providing an inside look into the efforts to gather and exploit intelligence during the past century, this book presents powerful ideas that can help guide present and future intelligence efforts. Though stories of WWII spying and codebreaking may seem worlds apart from social media security, computer viruses, and Internet surveillance, this book offers timeless lessons that may help today’s leaders avoid making the same mistakes that have helped bring at least one global power to its knees. The book includes a Foreword written by Bruce Schneier.
