With Hannah’s birthday coming up, Nancy is searching for the perfect present. When she spots a pretty apron with cherries embroidered on it, she knows Hannah will love it, especially because she’s going to be selling baked goods at the River Heights Cherry Blossom Festival.

But the apron holds an even more exciting surprise: inside the pocket, Nancy finds a scribbled note. After a little research help from Bess and George, Nancy thinks the apron might have belonged to famous baker Patty Crumbley and the note she found could be her rumored missing hundredth chocolate chip cookie recipe!

But soon, something else goes missing-the apron! Can the Clue Crew figure out who stole the apron before Hannah’s big day becomes a dessert disaster?
