Neither the painting nor Quick herself are what they appear to be. The picture is thought by the Skelton’s experts to be the work of a young Spanish Republican artist, Isaac Robles, whose striking images were bought by the American collector Peggy Guggenheim before his mysterious wartime disappearance. But we rapidly discover that the picture is actually by a young woman, Olive Schloss, who lived in Malaga with her parents, Harold, a Viennese dealer in modern art, and her fragile, depressive English mother, Sarah. After meeting Robles and his younger sister, Teresa, Olive became at first inadvertently and then deliberately embroiled in an ingenious artistic subterfuge.
