Declassified: From the Zimmerman Telegram to the Cambridge Five

Declassified explores some of the most remarkable revelations to have emerged from top secret documents brought to light in recent years. It ranges from revelations of spies and sleeper agents, such as Julius and Ethel Rosenberg, to the frankly bizarre Acoustic Kitty project, in which the US government trained cats to spy on the Kremlin, to the murky tale of the 'disappeared' citizens during Argentina's military dictatorship.

In this book, the author explores these remarkable projects, questions how seriously they were taken by the governments of the day and asks what the implications are of such efforts being conducted in our name without our knowledge.
