Clive Nolan & Oliver Wakeman - Second Light

(Watson: With Stapleton firmly leading his sister away, Sir Henry, a picture of dejection, set off for Baskerville Hall.
That night, I was awakened by Sir Henry, who had been disturbed by a strange sound. It was the butler, Barrymore, staring out into the blackness of the night, with a burning candle in his hand. Suddenly another light appeared on the moor.
With haste we embarked into the cold darkness to discover the source of this second illumination. Then we saw him. A face, ravaged by cruel experiments conducted during his many years in prison. There was a child-like look of confusion and fear in his eyes. It was Seldon!
Startled by our presence, he fled. )
