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.

Now that Catweazle has been introduced to life in King's Farthing, he needs somewhere to live. But where? And why is he so interested in the sign swinging before the Bull Inn? The sign of Taurus.

When burglars raid King's Farthing there are no prizes for guessing into whose hands the stolen property falls. Now Cedric tries to persuade the police that Catweazle is not the thief.

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

Lord Collingford is tempted to sell King's Farthing and Duck Halt to an up-and-coming property tycoon. Luckily for Catweazle, the tycoon turns out to be very very superstitious.

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.

Excitement grows as the local flower show gets under way in King's Farthing. But nobody is prepared for the effect of Catweazle's marrow-growing potion.

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?
