Gabriel Allon returns in the spellbinding new novel from the #1 New York Times-bestselling author. Two families, one terrible secret, and a painting to die for... It has been six months since Gabriel's showdown with Ivan Kharkov. Now, having severed his ties with the Office, Gabriel has retreated to the Cornish coast with only one thing in mind: healing his wife, Chiara, after her encounter with evil. But an unspeakable act of violence once again draws Gabriel into a world of danger when an art restorer is brutally murdered and the newly discovered Rembrandt on which he is working taken. Gabriel is persuaded to use his unique skills to trace the painting and those responsible for the crimes; but, as he investigates, he discovers there are terrible secrets connected to the painting, and terrible men behind them. Before he is done, he will have undertaken a journey through some of the twentieth century's darkest history-and come face-to-face with some of the same darkness within himself.
