Mystery Story Prompts: Kick-Start Your Chat

A mystery story prompt should give readers clues before it gives them answers. Start with an ordinary setting, one discrepancy, and a character who has a reason to investigate with you. The goal is not to make every person suspicious; it is to create a question you can test.

Prompt: the empty seat at dinner

“Play the host of a small reunion dinner. One place is set for a guest no one remembers inviting, and the name card uses a handwriting familiar to me. Describe the place setting and what you remember about the guest list. Ask what I notice on the card, but do not decide who sent it or reveal the answer.”

Prompt: the duplicate key

“You are a building manager who finds two keys stamped with the same room number. I am the tenant who requested a replacement. Explain why the old key should still be in your records, then let me choose whether we check the logbook or the room together.”

Make clues useful

Ask the character to keep a short list of facts and theories separate. When you introduce a new clue, see whether it updates the current explanation.
