Description
America's favorite baby-sitters are detectives, too!
It all started with a simple prank, which Kristy thinks is the work of Cary Retlin. Cary denies it, but offers Kristy a challenge: The BSC has six days to solve eight of Cary's puzzle-like clues. If they succeed, Cary will stop his tricks. If they fail...well, Kristy hates to fail.
In the middle of the contest, SMS is hit with some real vandalism. Has Cary changed the rules, or has someone else -- whose motives have nothing to do with fun -- joined the game?
