The Nancy Drew Notebooks #38: Candy is Dandy
As a special treat for her class, the school arranged for the kids to take a tour of Zuckerman's Zonked, which is candy factory in town. Mr. Zuckerman, who inherited the factory from his dad, gives them a tour and lets them sample some new candies. He makes a big deal out of his new candy, which will last as long as an all day sucker, be as sweet as chocolate, and as chewy as caramel. After showing them the recipe, he puts it in his pocket and gives them a tour of the library. It's only after going through some recipe books that he realizes his own recipe is missing. Nancy names her first and primary suspect as Josie, a girl in her class who wants to run her own candy company one day. Mr. Zuckerman tells them that the secret ingredient is maple syrup, which is why Nancy gets suspicious walking by Josie's house that night and smelling maple syrup. Josie shows up to school the next day with a new candy that tastes gross. She wanted to recreate the recipe for him.
