The defence of the realm: the authorized history of M15

For over 100 years, the agents of M15 have defended Britain against enemy subversion. Their work has remained shrouded in secrecy – until now.

This first-ever authorised history by Christopher Andrew reveals the British Secret Service as never before. It is a fascinating account of its inner workings, its clandestine operations, its failures and its triumphs.

M15 is the first major security or intelligence service in the world to give a historian free access of its records. Professor Andrew has used this unique opportunity to present an entertaining and authoritative guide to a fascinating subject. It is a riveting read with stories far more sensationally than anything seen on screen.
