Culled from archives around the world, the 50 documents in Declassified illuminate the secret and often inaccessible stories of agents, espionage, and behind-the-scenes events that played critical roles in American history. Moving through time from Elizabethan England to the Cold War and beyond, noted author Tom Allen places each document in its historical and cultural context, sharing the quirky and little-known truths behind state secrets and clandestine operations. Each of seven chapters centers on one particular theme: secrets of war, the art of the double cross, spy vs. spy, espionage accidents, and more. Through support and access provided by the International Spy Museum in Washington, D.C., this lively history contains never-before-published and hard-to-find documents-printed from scans of the originals wherever possible. These include The Zimmerman Telegram, which led America into World War I; letters from Robert Hanssen to his Soviet spymaster, marking the start of his devastating career as a mole; and papers as recent as the Presidential Daily Brief that announced that Bin Laden was determined to strike the U.S.-delivered in August 2001.
