John Hughes-Wilson is a former intelligence officer, and is ideally placed to reveal the secret history of military intelligence. He takes us "behind the scenes" of military and political events from Elizabeth I to Osama bin Laden and the crisis in the Middle East.  The book is divided into three parts. The first investigates some famous disasters when lack of intelligence was the decisive factor, e.g. Gallipoli and Dieppe. The second examines some equally famous examples of good intelligence being overlooked or ignored, e.g. the "bridge too far" battle of Arnhem. The last part goes behind the scenes of some famous successes, from the capture of Slobodan Milosevic to the defeat of IRA bombing campaigns and the arrest of a spy ring at the heart of NATO.
