Catweazle is back. Inevitably the return of the 11th century wizard for a new series of 20th century adventures spells trouble. Especially for Cedric, the 12 year old son of Lord and Lady Collingford who finds the magician hiding in his bedroom.

"Magic is magic" says Catweazle in one of his more profound moments. But even he seems confused when he meets a modern-day magician at a children's party.

When Groome loses his voice, Catweazle's efforts to find it reduce the residents of King's Farthing to a state of near hysteria.

Lady Collingford commands ghost hunters to be called to King's Farthing to investigate things which go bump in the night. Catweazle, of course, is doing some investigating himself.

Groome is seeing things - or is he? A London doctor is consulted, but he finds Catweazle a far more interesting case than Groome.

Catweazle has now collected all 12 signs of the zodiac. But he still needs to discover the 13th before he can fly. Will the great quest succeed in this last episode of the series?
