The Nancy Drew Notebooks #22: The Clue in the Glue (1998)

Nancy's class is in the middle of a science fair. George's dad helped her create a mobile of the planets on a wood base. Jason, one of the boys in their class, steals the bubbles that Nancy and Bess used for their project and starts tossing it around the room with these boys Andrew and David. The bottle knocks into the mobile, and one of the planets breaks. Mrs. Reynolds, their teachers, tells George that she can fix it in the morning.

When they get back the next day though, someone already fixed it. They left a note behind on paper with smiley faces on it, and Nancy finds a bottle of empty glue under the table. George tells them that she got a few other notes on the same paper and thought it was Bess because her family has the same paper. Nancy decides to investigate and find the culprit.

Andrew and Jason are the two main suspects. One note says that George is pretty, and Andrew keeps showing up to compliment her on random things. Jason shows off his project, which is invisible ink. He writes a message to show the class, and Nancy sees that it's on smiley face paper. Jason hides the paper from her, and when she tries to get it from him, he throws it away. David writes a note with the ink too.

George and Nancy keep passing notes to each other in class, and their teacher keeps warning them about it. She gives George one more warning and then catches her with one of the notes. Before George can explain, her teacher bans her from coming to the planetarium on their field trip and even calls her home to tell her mom. Nancy takes the last note, notices that it has a squiggle line under one word and realizes that David underlines things the same way. She solves the case, George gets to go on the field trip, and Nancy decides that boys aren't so bad after all, at least some boys.

*Nancy has a favorite sweater that is red and white with snowflakes on it. Bess has a favorite pink hat that she wears in cold weather, which has pink and white roses on the sides.

*The girls automatically assume that whoever sent George the notes is a boy because of the one that says she's pretty. That's kind of funny given that she gave off a lesbian vibe in some of the teen books.

*Instead of Togo, Nancy now has a puppy named Chip, which is short for Chocolate Chip.

*Nancy and Bess make frozen soap bubbles for their project. They blow bubbles outside in the cold until each one freezes and develops all these ice crystals on the outside. It kind of makes me wish it was still cold enough in Ohio to try this!
