From the Barnes & Noble review: "Antiterrorist expert Gabriel Allon would prefer to spend a quiet life as an art restorer, but events keep dragging him back into danger. In his eleventh book incarnation, Allon is strolling innocently with his wife in London when he spots a man who he instinctively identifies as a suicide bomber. Fate (in the form of a violent British undercover officer) unfortunately interferes before Gabriel can thwart the bomber's self-destructive mayhem, a detonation that marks the beginning of another Allon descent into riveting terrorist hunting. Subtle and suspenseful."
