"The Babysitter" is the twenty-third story included in the book Scary Stories to Tell in the Dark. The story is based upon the 1960s urban legend known as The Babysitter and the Man Upstairs (oftentimes shortened to The Baby-sitter or The Sitter), which would also inspire the 1974 film, Black Christmas (also known as Silent Night, Evil Night, and Stranger in the House); the 1979 film, When a Stranger Calls as well as its 1993 sequel When a Stranger Calls Back as well as a 2006 remake.
A babysitter is babysitting three children. The phone rings and she answers it. She hears a man laughing, she asks who he is and he hangs up. Then the phone rings again and he says "I will be there soon" and hangs up. He starts calling multiple times, saying that he will arrive soon and keeps hanging up, the babysitter and the children get very scared. The babysitter calls the police and they say that they will be right over. The man calls again and says "I'm coming now." and hangs up again. When the police get there they find out the man is upstairs and arrest him.
