You could write about a missing valuable artifact. Like a rare diamond that vanishes from a museum under mysterious circumstances.
You might consider a story where a person keeps receiving anonymous threatening letters. The sender's identity and the reason behind the threats could be the mystery to solve. Maybe it's related to a past event the protagonist has forgotten about.

A story about a 'Talking parrot who solves mysteries' would be great. The parrot could use its ability to talk to gather clues and help people.

Another is 'A group of mice planning a heist'. It's a fun and unique topic that can be full of humor and cleverness.
Stories of self - improvement are also great. Like someone who was shy but through continuous efforts in public speaking, finally became confident and good at expressing themselves in front of a large audience.
A time - traveling encounter. For example, a person accidentally travels back in time and meets their younger self. They have to deal with the consequences of this strange meeting and how it changes their perspective on life.
