Bedknobs and Broomsticks

In The Magic Bedknob, Carey, Charles and Paul 6 find prim Miss Price injured by falling off her broomstick. For their silence, she bespells a bedknob to carry them where-ever and when-ever. In Bonfires and Broomsticks two years later, they bring necromancer Emelius Jones to visit. But his neighbors want to burn him at the stake for disappearing in the Great Fire of London.
