Young librarian, Katie Nicholson discovers evidence of a past family scandal in a rambling old mansion and her life is now put in mortal danger.
Katie Nicholson is a dreamer, and trying to get over a failed love affair. She goes to crumbling mansion Epton Hall, following the death (intestate) of the elderly owner, to catalogue the vast library of books. The only known heir, (penniless Harold Hapsworth-Cole, living in Malta) can't wait to inherit Epon Hall's fortune. Whilst cataloguing books in the attic, Katie discovers a letter and a birth certificate written more than fifty years earlier, proving that another heir exists. Harold returns to England in secret to see the old mansion and overhears a telephone conversation between Katie and her employer about the letter. Following a scuffle he steals the evidence and locks her in the attic without light, food or water for the weekend.
Katie gradually becomes embroiled in a battle of inheritance, greed, intense hatred and attempted murder in a hospital room in Vancouver, before the fate of the old house can be decided.
