Seems I have seen that old movie!
'Bell, book, and candle' actually refers to a method of excommunication used by the Roman Catholic church, introduced by Pope Zachary sometime in the 8th century. It was saved for especially egregious sinners, like those accused of witchcraft, or marrying family members. Shakespeare referred to the practice in King John, when Philip of Faulconbridge says that "neither bell, book, nor candle shall drive me back, when gold and silver beckons me onward!" Something like that.
The Rolling Stones even used the phrase in their song Winter.
Bell, Book, and Candle was a Broadway play by John Van Druten before it was a movie with Jimmy Stewart and Kim Novak.
And before you accuse me of being a know-it-all, I didn't know most of this before I did the research to write this story!
