30 Story Ideas for Your Mystery Novel or Screenplay
When you’re writing a mystery novel or a screenplay that revolves around it, you’ll have to keep in mind some key elements to make it effective. Mysteries are like assembling pieces of a puzzle together and the folks who enjoy watching or reading them will be constantly trying to figure things out along the way. If your story is predictable, people may not even finish it.
The idea is to keep the reader or audience guessing. Aside from writing a compelling story with dynamic characters, this will be one of your main goals along the way.
Before reading the list of mystery story ideas below for your writing prompts, keep in mind these mystery tips.
Research the best mystery stories
Don’t just read or watch mystery movies you like, but find the ones the majority of the general audience loves as well. You want some of the most proven stories to be your bar for success.
Pay attention to every detail and recognize the clues.
After you watch or read the mystery and it’s revealed the ending, make sure to start over and look for all the clues that led up to the ending. Stories that don’t have the proper foreshadowing and clues are cheating. Every piece of the puzzle has to lead from one to the next.
The idea is not to “get over” on the audience, but you want them to feel like kicking themselves for not being able to figure out what was in front of them the entire time.
Make sure your opening is mysterious. Capture the reader or audience's interest immediately.
Establish right away that your story is based on a mystery. Don’t allow the reader or audience to wonder what type of story this might be. For example, crime mysteries open with the crime that has been committed. A story about a jewel thief may begin with the heist itself.
Make all your main characters a suspect.
When everyone has a reason to be a suspect in the story it allows you to misdirect the reader or audience at any given point. The “bad guy” may actually turn out to be a patsy and the “good guy” may actually turn out to be a murderous serial killer.
Try not to give the audience or reader what they expect.
