The recent growth of interest in intelligence and security studies has led to an increased demand for popular depictions of intelligence and reference works to explain the architecture and underpinnings of intelligence activity. Divided into five comprehensive sections, this Companionprovides a strong survey of the cutting-edge research in the field of intelligence studies:

• Part I: The evolution of intelligence studies;
• Part II: Abstract approaches to intelligence;
• Part III: Historical approaches to intelligence;
• Part IV: Systems of intelligence;
• Part V: Contemporary challenges.

With a broad focus on the origins, practices and nature of intelligence, the book not only addresses classical issues, but also examines topics of recent interest in security studies. The overarching aim is to reveal the rich tapestry of intelligence studies in both a sophisticated and accessible way.

This Companion will be essential reading for students of intelligence studies and strategic studies, and highly recommended for students of defence studies, foreign policy, Cold War studies, diplomacy and international relations in general.
