The world of secret agents and covert operations captures the imagination– but what do we really know about spies? I Spy uncovers basic details of four countries’ main espionage agencies, charting their origins, agents’ training, and common tools. Famous (or infamous) double agents, moles, and other spies are featured as the text emphasizes that a spy’s work is never done. Each book taps the reader’s inner sleuth as it presents a Top-Secret Activity that can be carried out at home. An early reader’s guide to CIA spies, introducing American espionage history, famous agents such as Aldrich Ames, technology such as spy satellites, and the dangers all spies face.
