The Ghosts of Motley Hall

American couple Darlene and Marvin Dewey are trying to trace Darlene's family tree; Sir George's brother Albert married Darlene's great-great grandmother, his older sister Alexandra never married but legend tells that his younger sister Clara eloped with an American and Mrs Dewey wants to know the truth. She has all sorts of gadgets to get in touch with spirits as she wants to ask Sir George.

A film crew descend on Motley Hall as historian St John Desmond details the house's history for School television, but as they portray incidents from Motley's past, the ghosts notice that the historian has it wrong. Can they, with the help of faithful Mr Gudgin, set the record straight before the name of Uproar is blackened forever?

The other ghosts feel that Sir George is becoming a tyrant and want to teach him some humility. Sir George seems to have an adverse reaction to his sister Alexandra's croquet mallet. The ghosts wonder what the story is behind this and if it can help them get out from under George's rule.

Alexandra Uproar is cold towards the other ghosts and bosses over Sir George; Matt has an idea of how to get her out, if Sir George can do what is required.

Mr Gudgin installs a piano in the hall and the ghosts plan a night of musical entertainment. The piano once belonged to composer Ludwig Stumpf, who doesn't want anyone else—dead or alive—to play it.
