Here are my reviews for the Perfect Mystery trilogy. "Perfect" might not be the best name for it, since the entire mystery hinges around tingly face cream. Also, it's clearly a two-book story, not a three-book one. It does have Nancy Drew entering a pageant, though!
In between books 2 and 3, they wrote Girl Detective Ghost Stories. My current plan is to review Ghost Stories 1 and 2, then do the Girl Detective version. That'll be it for book reviews for a while. I might do a review when I'm in California for the wedding, if I have enough free time (which I won't), since I think their library system has books that aren't available in Oregon.
