Moondial was a British television six-part serial made for children by the BBC. It was first broadcast in 1988 and has been repeated many times. It was based on the novel written by Helen Cresswell, who also wrote the TV adaption.
The plot follows a young girl named Minty (Siri Neal) who is staying with her aunt after her mother is injured in a car accident. Minty spends much of her time wandering around the grounds of a nearby mansion, and is drawn to a moondial that enables her to travel back in time, where she becomes involved with two children, Tom (Tony Sands), who lives in the Victorian era, and Sarah (Helena Avellano), who seems to live in “the previous century” to that, and must save them from their own unhappy lives.
