Body of lies - David Ignatius

Roger Ferris is one of the CIA's soldiers in the war on terrorism. He has come out of Iraq with a shattered leg and an intense mission - to penetrate the network of a master terrorist known only as 'Suleiman'. Ferris's plan for getting inside Suleiman's tent is inspired by a masterpiece of British intelligence during World War II: he prepares a body of lies, literally the corpse of an imaginary CIA officer who appears to have accomplished the impossible by recruiting an agent within the enemy's ranks.
This scheme binds friend and foe in a web of extraordinary subtlety and complexity, and when it begins to unravel, Ferris finds himself flying blind into a hurricane. His only hope is the urbane head of Jordan's intelligence service - a man who just might be an Arab version of John le Carr's celebrated spy, George Smiley. But can Ferris trust him? And can he trust the CIA?
