#1 New York Times bestselling author Daniel Silva delivers another stunning thriller in his latest action-packed tale of high stakes international intrigue.

The hunt is on for the greatest art forger who ever lived ...

Legendary spy and art restorer Gabriel Allon has at long last severed ties with Israeli intelligence and settled quietly with his beautiful wife and their young twins in Venice, the only place he has ever truly known peace.

But when the eccentric London art dealer Julian Isherwood asks Gabriel to investigate the circumstances surrounding the rediscovery and lucrative sale of a centuries-old painting, he is drawn into a deadly game of cat and mouse where nothing is as it seems.

Gabriel soon discovers that the work in question, a portrait of an unidentified woman attributed to Sir Anthony van Dyck, is almost certainly a fiendishly clever fake. To find the mysterious figure who painted it - and uncover a multibillion-dollar fraud at the pinnacle of the art world - Gabriel conceives one of the most elaborate deceptions of his career. If it is to succeed, he must become the very mirror image of the man he seeks: the greatest art forger the world has ever known.
