<P> Matilda Wormwood is a genius, but her parents, Harry and Zinnia, and her brother Michael ignore and mistreat her .

To pass the time, Matilda learns the route to the public library to read books . </P> <P> At age six - and - a-half, Matilda begins to lose patience with her parents, expressing a desire to go to school, which her parents refuse blatantly and mock her . In retaliation for her father constantly berating her, she resolves to punish him each time, first by adding hydrogen peroxide to his hair tonic to turn his hair an unhealthy blonde, and then gluing his hat to his head after learning about his cheating car business . Coincidentally, unlucky things begin to happen around Harry when Matilda gets angry with him . For instance, when reading a borrowed library copy of Moby - Dick, which Harry rips up and makes her watch television instead, her increasing anger causes the television set to suddenly explode . </P> <P> Harry finally relents to letting Matilda go to school after meeting a client named Agatha Trunchbull, the tyrannical principal of a rundown elementary school, Crunchem Hall .

That night, Miss Honey pays the Wormwoods a visit to encourage them to spend more time with Matilda, but they snub her .

Afterward, Miss Honey invites Matilda to her house for tea . On the way, they pass Trunchbull's house, and Miss Honey reveals a secret of hers: When she was two, her mother died, so her father, Magnus, invited his stepsister - in - law, Trunchbull, to live with them and look after her .
