Dawn Bosco's on her way to summer camp. She can't wait for the fun to begin, but when her shell mirror and a favorite pin disappear, it's time for the Polka Dot Private Eye to investigate. Dawn's sure one of the kids from the Coolidge School—a Cool-Itch Kid took her things. But she's forgotten her detective kit at home, so how can she solve the case? An unexpected offer of help leads Dawn to the answer, and, best of all, to a surprising new friend at camp.
