For Gabriel and his wife, Chiara, it is supposed to be the start of a pleasant weekend in London—a visit to an art gallery in St. James’ s, followed by a quiet lunch at an Italian restaurant along the Strand. But two deadly bombings in Paris and Hamburg change all that. While walking along Wellington Street, the ever-vigilant Gabriel notices a man whom he believes is about to carry out a third attack. Armed with a concealed Beretta pistol, he follows the man into the crowded Covent Garden market, determined to prevent the massacre of innocents he fears is about to take place. But before Gabriel can draw his weapon, he is knocked to the pavement by two undercover London police officers. A moment later he looks up to find a scene from his nightmares. Haunted by his failure to prevent the attack, Gabriel returns to his isolated cottage on the Cornish coast, believing his role in the affair is at an end. But when a summons arrives from the CIA, he is drawn once more into the world he thought he had left behind. Set against the disparate worlds of art and intelligence, Portrait of a Spy moves swiftly from the corridors of power in Washington, to the glamorous auction houses of New York and London, to the glittering streets of Paris and the unforgiving landscape of the Saudi desert. It features the most memorable cast of characters in contemporary fiction and a climax that will leave readers haunted long after they turn the final page.
