Where was the library key hidden?

• A. A violin case
• B. A book
• C. Under the doorknob
• D. In a drawer

Answer: (A)

Think about clues that hide something small by using an everyday object that wouldn’t raise much suspicion. A key can be tucked away in a container that people don’t check at first glance but that still makes sense within the setting. A violin case is a perfect fit because it’s a plausible place to store small items in a music or study area, and it can be looked at quickly without raising alarms. It blends into the environment, yet a careful observer would notice a violin case that seems out of place or has recently been used, hinting that something might be inside.

In contrast, hiding the key under the doorknob is very obvious and would likely be found immediately, which makes it an unlikely deliberate choice in a puzzle. A book could hide a key only if there’s a hollow or decoy clue pointing to a book, which isn’t suggested here, so it feels less natural as a hidden spot. A drawer is a common, easily searched place, so it doesn’t require much cleverness to rule out once you’re paying attention to the scene. The violin case stands out as a clever but believable concealment that fits the hidden nature of the puzzle.
