Gabriel Allon has been hailed as the most compelling creation since "Ian Fleming put down his martini and invented James Bond. A man with a deep appreciation for all that is beautiful, Gabriel is also an angel of vengeance, an international operative who will stop at nothing to see justice done. Sometimes he must journey far in search of evil. And sometimes evil comes to him.
For Gabriel and his wife, Chiara, it was supposed to be the start of a pleasant weekend in London - a visit to a gallery in St. James's to authenticate a newly discovered painting by Titian, followed by a quiet lunch. But a pair of deadly bombings in Paris and Copenhagen has already marred this autumn day. And while walking toward Covent Garden, Gabriel notices a man he believes is about to carry out a third attack. Before Gabriel can draw his weapon, he is knocked to the pavement and can only watch as the nightmare unfolds.
Haunted by his failure to stop the massacre of innocents, Gabriel returns to his isolated cottage on the cliffs of Cornwall, until a summons brings him to Washington and he is drawn into a confrontation with the new face of global terror. At the center of the threat is an American-born cleric in Yemen to whom Allah has granted "a beautiful and seductive tongue." A gifted deceiver, who was once a paid CIA asset, the mastermind is plotting a new wave of attacks.
