In Disrupt and Deny, Rory Cormac takes readers into the hidden world of British foreign intelligence activity. With extraordinary detail and easily accessible prose, Cormac’s work sets a standard for espionage history.

A young professor at Nottingham University, the author’s passion for the subject is clear. Still, Cormac’s passion is not unbound from his academic scrutiny. Throughout Disrupt and Deny, the author doesn’t simply tell us what happened; he explains why it happened. Cormac also reports on the lessons learned (and not learned). In doing so, he charts the organizational evolution and culture of various elements within the British intelligence apparatus.
