You decide to locate the giggling. You pull back a big blue puffy jacket and a bright pink scarf. No one is hiding there. The giggling must have been the wind outside. But beneath the pile of mittens, you see a small, folded note sticking out! It's written in messy, pencil-on-paper handwriting. It says: "Cupcakes for the surprise are in the big book corner. Meet me in the Library." You gasp! This changes your theory entirely. The cupcakes weren't stolen to be eaten by a greedy thief; someone took them to use as a surprise for something else! But for what? A student celebration? A secret teacher party? The note points to the Library. You must hurry to the location to uncover the secret plan.
