Harry Potter influences and analogues
Many critics have noted that Jill Murphy's "The Worst Witch" series (first published in 1974 by Allison & Busby), is set in a school for girls, "Miss Cackle's Academy for Witches", reminiscent of Hogwarts. The story concerns an awkward pupil at a boarding-school for witches, who faces a scheming rival student. Her professors include a kindly and elderly headmistress and a bullying, raven-haired potions teacher. Murphy has commented on her frustration at constant comparisons between her work and "Harry Potter": "It's irritating … everyone asks the same question and I even get children writing to ask me whether I mind about the Hogwarts school of witchcraft and pointing out similarities. Even worse are reviewers who come across my books, or see the TV series, and, without taking the trouble to find out that it's now over quarter of a century since I wrote my first book, make pointed remarks about 'clever timing' – or say things like 'the Worst Witch stories are not a million miles from J K Rowling's books'. The implications are really quite insulting!"
The Worst Witch
The novel begins with Mildred Hubble and the upcoming traditional assembly where all of the first-years are given their own black cats that they will teach to ride on their broomsticks with them. Unlike the other girls, who receive black kittens, Mildred receives a tabby cat, which she simply calls Tabby. The kitten is unable to sit on a broomstick, so Mildred carries Tabby in her bag. Miss Hardbroom disapproves and Mildred has to stop. Afterwards, another witch called Ethel Hallow teases Mildred about it, and dares her to turn her into a frog. Mildred loses her temper and turns Ethel into a pig instead.
