The second edition of Secret Intelligence: A Reader brings together key essays from the field of intelligence studies, blending classic works on concepts and approaches with more recent essays dealing with current issues and ongoing debates about the future of intelligence.

Secret intelligence has never enjoyed a higher profile. The events of 9/11, the conflicts in Iraq and Afghanistan, the missing WMD controversy, public debates over prisoner interrogation, together with the revelations of figures such as Edward Snowden, recent cyber attacks and the rise of ‘hybrid warfare’ have all contributed to make this a ‘hot’ subject over the past two decades.

Aiming to be more comprehensive than existing books, and to achieve truly international coverage of the field, this book provides key readings and supporting material for students and course convenors. It is divided into four main sections, each of which includes full summaries of each article, further reading suggestions and student questions:

* The intelligence cycle

* Intelligence, counter-terrorism and security

* Ethics, accountability and secrecy

* Intelligence and the new warfare

This new edition contains essays by leading scholars in the field and will be essential reading for students of intelligence studies, strategic studies, international security and political science in general, and of interest to anyone wishing to understand the current relationship between intelligence and policy-making.
