Plot

Conductor Timothy Clare and his family – wife, daughter and two sons – move into an old house in Bristol they had just bought from the elderly Mrs Betterton; the house having been in her family for generations. While exploring the garden, Timothy's two sons notice that the house has an extra window, and deduce that a hidden room may exist. After breaking through an upstairs wall and discovering an ancient dusty bedroom, a long-dead skeleton is found in the four-poster bed.
