Mysterious and thrilling fiction writing prompts.

Sometimes it’s hard to start a new writing project. Maybe you’re overwhelmed by too many ideas and can’t decide which one to tackle. Or maybe you’re searching for the right idea, something to spark your imagination and inspire your next story.

Fiction writing prompts are an excellent source of inspiration. They’re useful for generating new ideas, but they can also help you make breakthroughs in projects you’re already working on. If you’re stuck on a scene or chapter, you might find a fiction writing prompt that offers the seed of an idea to help you push your story forward.

All of today’s fiction writing prompts came from my book 1200 Creative Writing Prompts, which is available from your favorite online bookseller.

Fiction Writing Prompts for Mysteries and Thrillers

With these fiction writing prompts, there are no rules. Choose a prompt and then do whatever you want with it. Write a short story, start a novel, or outline a screenplay based on the prompt. Change the prompt. Combine two or more prompts. Most importantly, have fun!

  • The protagonist wakes one morning gagged and tied to the bed, and there’s a maniac sitting in the bedside chair.
  • Over the course of one week, five high-profile CEOs go missing. Were they abducted? Killed? Did they all run off to escape their high-pressure lives?
  • An old man or woman confesses a lifetime of secrets—many of which involve violence, torture, and murder.
  • The protagonist is blamed for a murder but doesn’t remember committing it—even though every shred of evidence along with a hazy memory suggests otherwise.
  • A group of young adults gets together to rent a cabin for a weekend. They drink and party, and the next morning one of them is found murdered. In the months that follow, the friends suspect each other and question themselves. Who did it? Will they figure it out before the police do?
  • A newlywed receives word that his or her spouse was killed in action. A few months later, the widowed protagonist starts receiving communications that could only be from his or her dearly departed spouse.
  • The protagonist buys an antique trunk from a junk shop and discovers a mummified body inside—a body that was murdered.
