‘She likes people,’ said the witch, striding ahead. ‘She cares about ’em. Even the stupid, mean, dribbling ones, the feckless and the silly and the fools who treat her like some kind of servant. Now that’s what I call magic – seein’ all that, dealin’ with all that, and still goin’ on. That is the root and heart and soul and centre of witchcraft, that is.
‘Mrs. Earwig tells her girls it is stars and circles and colours and wands. [They] are all very well as decoration, but the start and finish, the start and finish, is helpin’ people when life is on the edge. Even people you don’t like. Stars is easy, people is hard.’
