One interesting story could be about the great mouse detective solving a mystery in an old, abandoned cheese factory. The clues are hidden among the cheese wheels and old machinery.
There could be a fanfiction where the great mouse detective travels to a different part of the mouse world, a place filled with strange creatures and new challenges. He has to adapt to the different environment and customs while still trying to solve the mystery at hand. Maybe there's a series of disappearances that he needs to get to the bottom of, and he discovers that there's a much bigger conspiracy going on.
One idea could be a crossover with Sherlock Holmes in the human world. The great mouse detective could team up with Holmes to solve a mystery that spans both the mouse and human realms. Maybe there's a villain causing chaos in both worlds and their combined skills are needed.
The OC could be from a different part of the mouse world with unique skills, like being able to communicate with certain insects that can help in solving crimes. For example, they could get information from a spy spider about a villain's lair location. The OC then teams up with the great mouse detective to use this new lead to solve a big case.
One idea could be Basil solving a mystery in a new, strange part of the mouse city, like an abandoned underground area filled with old secrets. Another could be Basil teaming up with a new, young mouse detective in training to solve a case that's baffling the entire mouse detective community. Or perhaps a story where Basil has to solve a mystery on a ship sailing to a far - off mouse - inhabited island.
An OC who is a street - smart mouse with a network of informants all over the city could be interesting. This OC could come across a strange occurrence that they think Basil should know about, leading to a new adventure. They could provide Basil with valuable leads from their connections on the streets.
Obviously, the great mouse detective himself is very popular. His intelligence and charm draw readers in.
One way is to give the human a unique backstory. For example, if it's a detective in the Great Mouse Detective world, he could have a past that led him to be interested in solving cases in both the human and mouse worlds. Maybe he grew up near a place where the mice and humans interacted a lot, so he has a natural curiosity.
A human can be a helper. They could assist the mouse detectives by providing resources that are difficult for mice to obtain, such as certain tools or information from the human world.
Probably courage and problem - solving. The mouse detective must be brave to face the challenges and mysteries in the story. And he has to use his intelligence to solve the problems he encounters. Also, there could be a theme of community, where different mouse characters work together towards a common goal.
Definitely Sherlock Holmes. Since The Great Mouse Detective is inspired by Sherlock Holmes, a crossover with the original Holmes would be very interesting. They could compare and contrast their detective methods.
Well, it has the potential to be. The concept of a mouse detective is unique and interesting. In children's literature, having an animal as the main character is quite common, and if this novel has a well - crafted plot, memorable characters, and positive themes, then it can definitely be a classic.
