The moment artist Riana Evans sees the dilapidated mansion in Wales she longs to buy it, despite its unhappy past – 20 years ago, five maids died there in mysterious circumstances. So she is delighted when the house’s elderly and eccentric owner sells it to her for a pittance. The house’s "ghosts" prove good for business – inspiring her paintings and providing welcome atmosphere for a series of successful ghost-spotting weekends. Her personal life begins to look up too, in the form of handsome American airman Tom Maybury. But the mystery of the girls’ deaths hangs over everything, and Riana soon discovers that the house holds a secret, and there’s someone – or something – who’ll do anything to make sure she never discovers it.
