What Happens, Part by Part (Contains Spoilers)
Real witches
After his parents die in a car crash, the boy lives with his grandmother in Norway. She tells him that real witches look like ordinary women but are bald, wear wigs and gloves to hide claws, have square feet with no toes and can smell children. They hate children and want to get rid of them.
The hotel
The boy and his grandmother move to England. When his grandmother falls ill, they stay at a seaside hotel. The boy hides in a ballroom to train his pet mice and becomes trapped when a meeting of the “Royal Society for the Prevention of Cruelty to Children” begins. The women are witches.
Formula 86
The Grand High Witch reveals her plan: open sweet shops across England and sell sweets laced with Formula 86 Delayed Action Mouse-Maker, turning children into mice. She demonstrates on Bruno Jenkins. Then the witches smell the boy, catch him and turn him into a mouse.
Fighting back
The boy, still able to talk, escapes to his grandmother, who believes him at once. Together they steal a bottle of the formula from the Grand High Witch's room. The boy sneaks into the hotel kitchen and pours it into the witches' dinner.
The ending
At dinner, the witches turn into mice and are killed by the hotel staff. The boy remains a mouse, but he is happy, because mice live only about nine years, which means he and his grandmother will die at about the same time. They plan to use the Grand High Witch's money and formula to destroy all witches in America.
