Captured first by the Nazis and then the Russians during World War Two, Percy Crow escapes in the bilges of a freighter from Soviet Russia to Hamburg. There, he sells his secrets to the head of British Intelligence. But when Lord Maudlin Paterson hears Percy’s account of the royal family's dark secrets, he sets out to find whatever the repulsive truth may be. Years after Maudlin’s death, the daughter of his illegitimate Russian son suddenly blurts out Percy’s name while being interrogated by the CIA - and Harry Paterson, Maudlin’s legitimate great-grandson, is the only person he trusts. Can Harry discover his great-grandfathers secrets, hidden in the distorted mirrors of photographs at the back of an album? Along with his lifelong friend George Northcliffe and the beautiful Serena Abenazo, he starts unravelling the clues. But where will the rattling bones of the sepia images lead him?
