The Defence of the Realm: The Authorized History of MI5 (Paperback) Christopher Andrew (author)

For over 100 years, the agents of MI5 have defended Britain against enemy subversion. Their work has remained shrouded in secrecy – until now.

This first-ever authorized account reveals the British Security Service as never before: its inner workings, its clandestine operations, its failures and its triumphs.

‘Definitive and fascinating … whether reporting on Hitler in the 1930s, the Double-Cross System of the second world war, Zionist terrorism, the atom spies, the Cambridge spies, the so-called Wilson plot or the 1988 shooting of the IRA bombers in Gibraltar, this book is essential reading’ Alan Judd, Spectator
