What are some plot ideas for mystery novels?

One idea could be a murder in a small, seemingly idyllic town. The victim is a well - liked local figure. The detective discovers that there are many secrets hidden among the townsfolk. Everyone seems to have a motive, from the local business owner who was in financial trouble with the victim to the jealous neighbor. Clues start to emerge, like a strange symbol found at the crime scene that leads the detective on a wild goose chase through the town's history.

One idea could be that Mystery Girl has a special power that only Pearl can understand. For example, she can communicate with ancient sea creatures, and Pearl helps her to control this power. Another could be that they go on a journey to find a lost gem that has a connection to both of their pasts. Maybe it was a gem that was important in the history of Pearl's homeworld and Mystery Girl has a vision about it.

An OC could be a Muggle - born with a very special family heirloom that turns out to have magical properties once they arrive at Hogwarts. This heirloom could be the key to solving an ancient mystery within the castle walls, like a hidden chamber or a long - forgotten spell.

One idea could be a story where the main character, a Pokémon in the mystery dungeon world, discovers a hidden power within themselves that no one else has. This power could be the key to saving the Pokémon world from an impending doom, like a strange and powerful dark force that is corrupting the dungeons. Another plot could revolve around a Pokémon who wakes up in the mystery dungeon world with no memories at all, and has to go on a journey to find out who they really are and where they came from. They might encounter various Pokémon along the way that seem familiar but can't quite place them.

One idea could be a story where the protagonist, a Pokémon transformed into a human - like form in the Mystery Dungeon world, discovers a hidden power within themselves. For example, a Pikachu might find out it can control a new type of electricity that no one has seen before. This could lead to them being both feared and revered among the other Pokémon in the dungeon.

One idea could be a small town where people start receiving anonymous threatening letters. The main character, a local journalist, decides to investigate. As they dig deeper, they find that the letters are related to a long - forgotten town secret from decades ago involving a powerful family who will do anything to keep it buried.

Well, a plot idea could be that Charmander is wrongly accused of causing chaos in the Pokemon Mystery Dungeon. It has to prove its innocence while also dealing with other Pokemon who are now afraid of it. It could go on a journey within the dungeon to find the real culprit. Another interesting plot is that Charmander finds a magical item that gives it the ability to talk to other Pokemon species in their own languages. This new power helps it form alliances and solve mysteries in the dungeon that were previously unsolvable. And also, a story where Charmander has a prophetic dream about a great disaster in the dungeon and has to convince other Pokemon to take action before it's too late.

One idea could be that Pikachu wakes up in a strange part of the mystery dungeon with no memory of how it got there. It has to team up with other Pokemon it meets along the way, like a Charmander and a Squirtle, to figure out the mystery of the dungeon and also find a way to get back home.

One idea could be that Pearl and the Mystery Girl meet by chance in a art gallery. Pearl is there admiring some sculptures and the Mystery Girl is looking at paintings. They start a conversation about their different tastes in art which leads to them getting to know each other better.

One idea could be exploring a character's backstory that wasn't fully covered in the game. For example, delving deeper into the family history of a side character. Maybe they have a hidden connection to one of the main wizarding families. Another plot could involve a new mystery within Hogwarts, like a secret chamber that has been long forgotten but holds a powerful magical artifact. A third idea would be to create an alternate timeline where a major event in the game didn't happen, and see how it changes the relationships and the overall story at Hogwarts.
