The Clifton House Mystery is a British children's cult television supernatural drama series written by Daniel Farson and Harry Moore, produced by Patrick Dromgoole and directed by Hugh David, and shown in 1978 by HTV for ITV.

The Clares' daughter Jenny is visited by the ghost of a kindly old woman who appears to be summoned by a music box left behind by Mrs Betterton's granddaughter.

A dragoon's helmet that the boys had bought at Mrs Betterton's contents auction starts to glow mysteriously; and a blood-like liquid drips through the ceiling onto some dinner party guests.

After checking local records, they realize that it may be the ghost of a dragoon commander called George Bretherton who was court-martialled for his lenient handling of the rioters, and who subsequently disappeared without trace.

The helmet stops glowing and the ghost of the old lady – apparently the dragoon's mother – is no longer seen; the music box which summoned her ceases to function and all returns to normal.
