Jim and his family seem to have fallen victim to a curse, and decide to go back to sea. If not, they are in danger of being turned into “landlubbers” just like their house, which is magically cleaned and nicely decorated in their absence. Matilda doesn’t believe in this so-called curse and sets out with a “scared-but-not-admitting-it” Jim to expose the fraud… For there is a Mrs. Bevan, well intent on making the pirates leave. And Matilda will stop her!
