With unprecedented access to the R.A.W. and the I.S.I., the world's most inscrutable spy agencies, Adrian Levy and Cathy Scott-Clark describe the workings of bitter rivals, mapping their complicated history from the 1960s to the present day. From the Parliament attacks to Pulvama, 9/11 to Osama bin Laden's assassination, the rise of terror's shadowmies to the fall of Kulbhushan Jadhav, here are some of the key events that have shaped the region, told from the split viewpoints of duelling enemies.

Levy and Scott-Clark also uncover a darker seam - of the destructive impact of C.I.A. interference, and how the I.S.I. fought for its life against dark forces it once funded, while the R.A.W. created ghost enemies to strengthen its hand.

Revelatory and unputdownable, Spy Stories clears the fog to reveal the spies and their assets, as you have never seen them before.
