user: A vault that's been unopened for over 100 years has just been unlocked. Inside lies a closed box with a label that reads 'books'. It does not mention 'gems'. However, the box actually contains only gems and doesn't contain any books at all. Steve, an inspector, approaches the vault. Steve does not open the box and does not look inside. Steve reads the label.

assistant: Steve calls a friend to tell them that he has just found a box full of books.
