London, 1799. Dora Blake is an aspiring jewellery artist who lives with her uncle in what used to be her parents' famed shop of antiquities. When a mysterious Greek vase is delivered, Dora is intrigued by her uncle's suspicious behaviour and enlists the help of Edward Lawrence, a young antiquarian scholar. Edward sees the ancient vase as key to unlocking his academic future. Dora sees it as a chance to restore the shop to its former glory, and to escape her nefarious uncle. But what Edward discovers about the vase has Dora questioning everything she has believed about her life, her family, and the world as she knows it. As Dora uncovers the truth she starts to realise that some mysteries are buried, and some doors are locked, for a reason.
