The 7th Series was originally broadcast between the 9th October and 11th November 1978, consisting of 6 episodes, three two part stories.

The Series introduced a young Scottish lad Andrew Forbes (Nigel Rhodes).  Nigel had previously worked as an extra on A Much Needed Holiday, but became more known to Roger Price when he worked on his 1977 comedy series, You Can't Be Serious. 

Nigel was delighted to win the role, as he was a great fan of the show. Andrew is introduced after he starts using his psychic powers to conjure up images of ghosts so as to provide a tourism attraction for the hotel owned by his father. 

Elizabeth also returned from her year on the Trig.
