Back Cover

Kristy, Claudia, Mary Anne, and Stacey have had some strange adventures since they started the Baby-sifters Club. But nothing’s been as spooky as what's going on right now. The baby-sitters have been getting mysterious phone calls when they're out on their jobs. When a phone rings and they pick up, there's no one on the other end of the line.

Claudia's sure it's the Phantom Caller, a jewel thief who's been operating in the area. Claudia has always liked reading mysteries, but she doesn't like it when they happen to her. So she and the baby-sitters decide to take action — with some very mixed results!

Main Plot

Claudia has been read The Phantom of Pine Hill, the 42nd volume in the Nancy Drew series and very spooky according to Claudia. Mimi walks in to help Claudia with her homework, and Mimi tells Claudia about when she was a child in Japan. Claudia gets a phone call from Stacey McGill about phone calls for the BSC, and Claudia goes back to read The Phantom of Pine Hill.

At Kristy's house for the weekend, Kristy, Claudia, Mary Anne, and Stacey are bored. Mary Anne has her glasses on and has a copy of the Stoneybrook News. She then spots that the Phantom Caller, the sneaky jewel thief that robbed homes in Mercer, is on a rampage to Stoneybrook! Claudia could not believe it. She was sitting for the Marshalls' then the phone started to ring, and when she called, the caller hanged up! Kristy then tells everyone that in 5th grade, her worst enemy, Alan Gray, pulled a prank on her, and Alan had a crush on her ever since. But, Claudia, still angry about the Phantom Caller, tells Kristy to start the first emergency meeting of the BSC, and Kristy agrees.


The BSC is getting ready for the school dance and deciding if they should go or stay home. They wonder what to wear and who to ask. Claudia has her eyes on her recent crush, Trevor Sandbourne! Will he notice her?

Ann M. Martin's Dear Reader letter

Dear Reader,

When I was young, my friends and I used to baby-sit a lot, and sometimes my best friend, Beth, and I would get scared when we were sitting at night. We thought we should develop a telephone code so that we could alert each other in case of trouble. The way the code was supposed to work was that if I sensed trouble I would call Beth, give her a code word, and then she would call the police for me. Of course, we never had a phantom phone caller like Claudia did, and we never had to use our code, but we had a lot of fun scaring ourselves. Later, when I began to write the second Baby-sitters Club book, I remembered my sitting adventures with Beth and used them to help tell the story.

It’s okay to be afraid when you’re baby-sitting at night. That’s natural. I know I was sometimes scared even when I didn’t need to be, and that was because I read a lot of mysteries, especially Nancy Drews, just like Claudia. Since I liked reading mysteries so much, I decided I would try to write one. So Claudia and the Phantom Phone Calls became the first mystery in the Baby-sitters Club series. Several more followed, and they were so popular that soon we launched the Baby-sitters Club Mysteries.
