The #1 New York Times bestselling author, best known for his long-running thriller series starring spy and art restorer Gabriel Allon, is back with The Other Woman, a modern tale of espionage, love, and betrayal.

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. He and the Russians will engage in an epic showdown, with the fate of the postwar global order hanging in the balance. Gabriel’s quest for the truth will lead him backward in time to the twentieth century’s greatest act of treason and, finally, to a spellbinding climax along the banks of the Potomac River outside Washington.

In conversation with Tim Wendel, writer-in-residence at Johns Hopkins University and the author of 13 books including Cancer Crossings: A Brother, His Doctors and the Quest for a Cure to Childhood Leukemia. Book signing to follow.
