The Clifton House Mystery.

An old woman's possessions are auctioned, and orchestral conductor Timothy Clare and his family move into her large, though rather gloomy and dilapidated, old house in Bristol. It soon becomes clear that this is a house full of secrets, and that Mrs. Betterton had good reason to leave with her young granddaughter, the ethereal, otherworldly Emily; after a series of frightening experiences and disturbing discoveries - including a walled-up room containing a skeleton - the Clares realise that they are not the only occupants.
