Judith is a successful novelist, but she's a little sensitive. She's from a good family, even if that family favours her more beautiful sister. She loves a drink (or three) but isn't sure if she loves the handsome doctor who is courting her. She yearns for a romance to yield to but remains a virgin. Judith receives visions from the saints.

Then Judith meets Gavin, a handsome and charming baron, at a wedding on the Cornish coast. His love transforms her from a plain, lonely girl into a beautiful, glamorous woman overnight. After a whirlwind honeymoon in Paris, he whisks her away to a Gothic castle in the countryside. But soon her perfect marriage begins to fall apart and she finds herself trapped in a nightmare, as her husband's mysterious nature, and his alternation of charm and violence, become more and more confusing and frightening. And then there are those whispers amongst the staff, unsettling rumours from London, and strange rattlings from the crypt...
