Lily, a curious fifth-grader, loved solving puzzles and uncovering secrets. One day, as she was cleaning her room, she noticed that her favorite pendant was missing. This pendant had been a gift from her grandmother, and Lily was devastated to find it gone.

Determined to uncover the mystery, Lily started her investigation. She carefully examined her room, searching for any clues that might lead her to the missing pendant. After a thorough search, she found a small piece of thread near her desk, which she carefully placed in a plastic bag to examine later.

Lily knew she couldn't do this alone, so she enlisted the help of her best friend, Max. Together, they began to piece together the puzzle, questioning anyone who had been in Lily's room recently. They soon discovered that Lily's younger brother, Zach, had been seen playing near her desk earlier that day.

With this new information, Lily and Max confronted Zach, who at first denied taking the pendant. But after some gentle questioning, Zach admitted that he had been curious about the pendant and had accidentally knocked it off Lily's desk, where it had fallen behind a bookshelf. Relieved to have found the pendant, Lily thanked Zach for his honesty and promised not to tell their parents, as long as he promised to be more careful in the future.
