Revenge me. For I am murdered . . .

Odette and Cecilia are young women, living between their grand homes in Hampstead and the imposing, ancient Herne House in Suffolk. Though Odette's artist mother Lydia keeps a tight grasp on her, she and her beloved Cecilia are mostly left free to roam, to learn and to love.

But when Lydia inexplicably sickens and dies, a dark veil falls. As the funeral rites are performed, Odette's aunt, the cold and implacable Claudine, increasingly takes charge of the household, while her father retreats to his study. Odette, lost in grief, disappears into the shadows.

But as Claudine is announced as Odette's new stepmother, a sinister presence in the house makes itself known. To her horror, Odette realises that despite her death, Lydia never really left. And now she wants revenge . . .
