979 Best Mystery Story Ideas and Prompts

For a mystery story to be considered effective, it needs to have an exciting storyline, fascinating characters, and thrilling puzzles. It should also be written in a way that would want readers to keep turning its pages. Because of all of those elements, it may seem difficult to create a good mystery story, but it is actually not. With the right inspiration and some creativity, you can eventually create your own mind-blowing mystery fiction. 

One thing that can keep you inspired are writing prompts. Whether they are a few paragraphs-long, a short phrase, or even just one word, writing prompts can bring out your creativity and provide you many other benefits. For once, it puts you out of your comfort zone and exposes you to new ideas, worlds, and perspectives. It also gives you the opportunity to write about topics that are outside of your preferred niche or genre.  

Another benefit of writing prompts is that it also helps you shift your mindset when you are trying to write a story from a genre that you are not used to. For instance, if you  specialize in writing detective novels and you have trouble writing caper stories, you can search for prompts that would inspire you to tell a story from the point of view of criminals to get started.   

Writing prompts can also shift your focus and help you break through a writer’s block. If you are feeling distracted or uninspired to write your story, you can use a prompt to spice up your plot or change a scene. 

Best of all, writing prompts can make you a better writer. By challenging yourself to write stories inspired by prompts regularly, you can enhance your writing style, exercise your imagery, hone your grammar, and improve your narrative.
