In late 2009, CIA officers in Afghanistan€s Kabul station allowed a Jordanian doctor into their closest confidence. In truth, the doctor was an al-Qaeda double agent€"and when he blew himself up, the station€s most senior officers died with him.
Years later, the station still hasn€t recovered. Recruiting has dried up and the agency€s best Afghani sources are being eliminated. At Langley, the CIA€s chiefs begin to suspect the worst: somehow, the Taliban has infiltrated the station.
When they ask John Wells to investigate, he reluctantly agrees to return to the country where his career began. One thing is certain: Americans are dying, and an American is responsible. Wells is the only one who can unearth the truth€"if it doesn€t bury him first . . .
