Lauren O'Farrell is an "art detective" who made it her mission to retrieve invaluable artworks stolen by the Nazis during the darkest days of World War II. Her quest leads her to the Manhattan apartment of elderly Isabella Fletcher, a woman who lives in the shadow of a terrible history-years ago her mother was rumored to have collaborated with the Nazis.

But as Isabella reveals the events of her mother's life, Lauren finds herself immersed in an amazing story of courage and secrecy as she discovers the extraordinary truth about a priceless piece of art that may have survived the war and the enduring relationship between a mother and a daughter.
