Flash fiction is a style of fictional literature that is characterized by extreme brevity. It typically ranges from 5 to 1,500 words. Despite its short length, however, it remains a full, self-contained story that possesses a beginning, a middle, an end, and a clear narrative arc.

Use one or more of the following prompts to write a piece of flash fiction today. Then share what you come up with in a comment or subscriber chat thread so we can admire and discuss it.

1. An Unusual Inheritance

A character receives an unusual inheritance, but there’s one bizarre condition or clause in the will they must fulfill within 24 hours to claim it.

Focus on: Pacing and Tension

Use the ticking clock to control your story’s rhythm. Vary sentence length to build urgency by using short, punchy sentences during high-stakes moments and longer ones when your character pauses to think or plan.

2. Untrustworthy Mirrors

Write a story that ends with the line: “And that’s why I never trust mirrors anymore.”

Focus on: Reverse Engineering and Story Structure

Start with the ending of your story and work backward. Ask yourself: What event, or chain of events, would make this conclusion inevitable? This constraint allows you to plant seeds in the story early that will build toward a satisfying payoff.

3. An Untranslatable Discovery

A linguist discovers a word in an ancient language that has no direct translation in any modern tongue or dialect. But when they finally understand its meaning, everything changes.

Focus on: Showing, Not Telling

Instead of outright explaining what the word means, reveal its meaning through your character’s reactions and choices, as well as others’ responses to what your character says and does. Let readers experience the discovery through sensory details, dialogue, and behavior rather than line after line of exposition.

4. A Voicemail from the Future

Someone wakes and finds a voicemail from themselves, sent from three hours in the future, warning them about something that hasn’t happened yet.

Focus on: Character Development and Voice

Use the voicemail to establish your character’s personality through their speech patterns and word choices, basing those things on what they choose to say, as well as do, when they’re under pressure. Consider: How would this person talk to themselves when they’re stressed or concerned? How would they react in stressful situations? And what would they prioritize when time is running out?

5. The Museum After Hours

A security guard who works overnight at a museum starts noticing that one painting’s details change slightly each night over the course of a few days. And tonight, they notice there’s a new figure in the background of the painting that looks disturbingly familiar.

Focus on: Atmosphere and Sensory Detail

Build the mood of the story through specific, concrete details. Consider: What does the museum smell like at 2 AM? What sounds echo in the empty galleries? Use all five senses to immerse readers in the unsettling environment the security guard is experiencing.
