She even gets help from her glamorous new neighbor, Mariella. As the girls hunt for clues around Maiden Rock, they encounter a cast of unlikely characters. And if Quinnie’s hunch is right, the search may lead them right into danger . . . This hilarious and page-turning debut is the perfect whodunit story for middle school sleuths.
