The Witches

The Witches by Roald Dahl

The witches are having a convention a local hotel. They look a lot like normal women, though there are some subtle differences (like the lack of toes). A boy is with his grandmother at the hotel. There is also another snobbish boy with his parents. The witches create a potion to turn them to mice. Even though they have mouse bodies, they still have their brains and can talk. They hatch a plan to take down the witches by putting the potion in their soup. After some harrying mouse moves they do it, and the witches become mice, thus saving the lives of many kids. The book has plenty of Dahl's dark humour.
