Oh, and at the end of the story, Nancy, after conveniently stumbling through random clues, finds a treasure in South America that the goverment has been trying to find for hundreds of years. Of course.
- This book has some of the lamest cliffhangers ever. The crossword cipher (it's carved on a piece of rare wood) is missing! Gasp! Oh, wait, Hannah put it away for safekeeping. Phew! Nancy is on the edge of a cliff when someone tries to...throw paint on her! Oh, the suspsense!
- The narration gets really "judgy" about Bess's love of food in this book. Leave Bess alone, ghostwriter.
- The Crossword Cipher gets stolen for real eventually, and the girls locate it in a shop in South America. The plaque's owner says that it's really hers, and the shop owner (who doesn't know her from Eve) just takes her word for it. Well, that was solved easily.
