Jessica Wakefield is convinced that Mary Wallace has disappeared. No one has heard a word from her in three days. She hasn't been in school, she didn't show up Lila's ice cream party, and worst of all, the Unicorns' treasury money seems to be missing. What's more, Mrs. Wallace, Mary's mom, is acting very strange.
Jessica's twin sister, Elizabeth, thinks that Jessica is just being her usual overdramatic self, until the twins get a mysterious amd confusing phone message. Maybe Jessica's idea isn't so farfetched after all. Maybe Mary has been kidnapped. If that's the case, Mary is in big trouble . . . and the twins had better figure out that cryptic phone message fast.

"You took a telephone message two days ago and didn't tell us? Jessica demanded. She sounded angry. "Who was it?"
"I don't know," Steven said vaguely. "I don't really remember. Some girl. She said to tell you something about money. She needed money and had to get away. Or she had money and needed to get away. Something like that."
The twins looked at each other. Elizabeth knew they were both asking themselves the same question. Could the call have been from Mary?
"Elizabeth," Jessica said lowering her voice, "you don't suppose that Mary needed the Unicorn money for something, do you?" She sounded very worried. "Something like running away?"
Elizabeth shook her head. "If Mary was in that kind of trouble, she'd come to us," she said. "She wouldn't just take the money and go."
Jessica nodded. She knew Elizabeth was right. But that didn't help to answer the questions that weighed on Jessica's mind.
If it wasn't Mary who called, who was it?
And where was Mary?
