As the royal wedding of Princess Elizabeth and Prince Philip whips post-war Britain into a fever, a mysterious traitor has emerged from the shadows of their Bletchley Park past, and now Osla, Mab, and Beth must resurrect their old alliance and crack one last code together."--Provided by the publisher.
