Haunted by his failure to stop a suicide bomber in London, Gabriel Allon is summoned to Washington and drawn into a confrontation with the new face of global terror. At the center of the threat is an American-born cleric in Yemen who was once a paid CIA asset. Gabriel and his team devise a daring plan to destroy the network of death- from the inside- a gambit fraught with risk, both personal and professional. To succeed, Gabriel must reach into his violent past. A woman waits there- a reclusive heiress and art collector who can traverse the murky divide between Islam and the West. She is the daughter of an old enemy, and together they form an unlikely and dangerous bond.
