Claudia and the Phantom Phone Calls

Kristy, Claudia, Mary Anne, and Stacey have had some strange adventures since they started the Baby-sitters 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 at 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 her friends decide to take action–with some very unexpected results!
