Espionage is one of the most secret of human activities. It is also, as the popularity of spy stories suggests, one of the most intriguing. This book pulls the veil back on the real world of espionage, revealing how spying actually works. In a refreshingly clear, concise manner, Kristie Macrakis guides readers through the shadowy world of espionage, from the language and practice of spycraft to its role in international politics, its bureaucratic underpinnings, and its transformation in light of modern technology. Espionage is a mirror of society and human foibles with the added cloak of secrecy and deception. Accordingly, traces spying all the way back to antiquity, while also moving beyond traditional accounts of military and diplomatic intelligence to shine a light on industrial espionage and the new techno-spy. As thorough—and thoroughly readable—as it is compact, the book is an ideal introduction to the history and anatomy of espionage.
