In an isolated village in the mountains of Andalusia, a mysterious Frenchwoman begins work on a dangerous memoir. It is the story of a man she once loved in the Beirut of old, and a child taken from her in treason’s name. The woman is the keeper of the Kremlin’s most closely guarded secret. Long ago, the KGB inserted a mole into the heart of the West --- a mole who stands on the doorstep of ultimate power. Only one man can unravel the conspiracy: Gabriel Allon, the legendary art restorer and assassin who serves as the chief of Israel’s vaunted secret intelligence service. Gabriel and the Russians will engage in a final epic showdown, with the fate of the postwar global order hanging in the balance.
