This is the story of a cat a broomstick & an ordinary schoolgirl called Rosemary. She bought them both in the market quite cheaply. Of course neither the cat nor the broomstick were just what they seemed & they turned up just when Rosemary badly needed something nice to happen to her. A good cat is apt to be independent so she did not have things all her own way & as Carbonel proved to be a Royal cat in a very special sense that was understandable. Between the cat & the broomstick Rosemary picked up some useful spells & magic & the adventures they brought about turned a dull-looking holiday into one long to be remembered for its unexpected excitements & rewards.
