Baby-sitters Beware — Ann M. Martin

America's favorite baby-sitters are detectives, too!

Nobody wants to believe it, but it looks as though someone is out to get the BSC. Stacey is nearly run down by a speeding car. A fire is set at Claudia's house. A rock is thrown through Kristy's window. Everybody hopes the trouble will stop when Kristy, Stacey, Claudia, and Abby head to Shadow Lake with Kristy's family for a ski weekend.

But the incidents continue...and they're getting scarier. Plus, the clues just aren't making sense. Then, back in Stoneybrook, a new lead turns up. Could the stalker be someone from the BSC's past?
