Back Cover Summary[]

Mary Anne should never have thrown away that chain letter she got in the mail. Ever since she did, bad things have been happening to everyone in the Baby-sitters Club. With Halloween coming up, Mary Anne's even more worried -- what kind of spooky thing will happen next? Then Mary Anne finds a new note in her mailbox: Wear this bad-luck charm, it says. OR ELSE. Mary Anne has to follow the note's instructions. But who sent the charm? And why did they send it to Mary Anne? The BSC might never see an end to their bad luck if they don't solve this mystery soon!


Set before Halloween, Mary Anne gets a chain letter in the mail which orders her to send out 20 copies of the letter or not only she would have bad luck, but her friends and family will too. After Mary Anne ignores the letter, bad things start happening to her & her friends.

A few days later, Mary Anne gets a necklace in the mail which orders her to wear the bad luck charm. Even though Mary Anne doesn't want to, the rest of the BSC thinks that she should. The BSC tries to find a good luck spell, but to no avail.

After Mary Anne attends her school's Halloween Hop with Logan, she finds a note taped to her door telling her to appear at Old Hickory's grave at the cemetery on Halloween at midnight. After calling the rest of the BSC, everyone decides to go for it (with Kristy using a late night slumber party as a cover).

In the end, it is discovered that Cokie Mason was responsible for the whole thing, so the BSC decide to get back at Cokie and her friends. The BSC goes to the cemetery, rigs up some bedsheet ghosts with a sound effects tape, flashlights, and scary masks for effect. When Cokie and her friends arrive, the BSC scares them.

Differences between the book and graphic novel[]
