It is 1917 and Charlotte Blackshaw is only eight years old when her little sister Victoria vanishes from the magnificent country estate of Tyringham Park. The feverish search for Victoria soon uncovers jealousies and deceits that the inhabitants of the grand house have fought for years to keep hidden.
As Charlotte grows, she believes that her mother and others wish that it was she who'd disappeared, rather than pretty, enchanting Victoria. Terrorised by her nanny, she becomes intent on escaping the confines of the estate that once she loved.
But Tyringham Park and its mysteries will never release their hold on her . . .
