A Recipe for Great Mystery Writing
One of the best ways for writers to challenge themselves is to try their hand at new and different genres. A writer who is accustomed to writing fictional short stories or personal narratives can expand their skill set and sharpen their style by dabbling in different genres, such as mystery writing.
Now…
Mystery writing stands out from other genres because it tends to require writers to do more planning in advance.
Plus…
In order to become an effective mystery writer, you may want to practice each and every day. Indeed, anyone who wants to explore this writing style — or who dreams of one day publishing a mystery novel — should begin a journal and use mystery writing prompts to hone their skills.
Of course, the characters in mystery writing can be as complex as the plot twists you can create. A secret Santa, the local police chief or a small-town sheriff, a young girl, or an old woman who fakes her own death on a family vacation could all be the main character in your story – or maybe a dead body is your story’s protagonist. The character options are positively endless in creative writing!
These mystery writing prompts are only a starting point. You can use one of these prompts in order to create a detailed and involved mystery, or you can practice until you come up with your own story idea.
No matter which route you choose, you should always make sure to keep on writing!
