Top secret. The book of spies and agents

From ancient Rome to Tudor England and up to the 20th century, the art of espionage has come a long way. But one thing has never changed-humans have always found surprisingly creative ways to gather top secret intelligence. This book presents eight of the most notorious spies in history, from Queen Elizabeth I's 16th-century spymaster to the Serbian-born agent who may have inspired the character of James Bond.
