One chapter, your move
This is what a move can look like – short or long, combined however you like. The AI writes the next chapter from exactly your words.
The suspect has asked for a glass of water four times, and each time he drinks at the exact moment you mention the boathouse. His alibi is solid: three witnesses, a dinner bill, a photo with a timestamp. Too solid. Behind the one-way mirror the inspector is losing patience. You have ten minutes before his lawyer arrives – and one question you haven't asked yet.
Your move
Do
I put a fifth glass of water in front of him, then lay the dinner bill next to it – folded so that only the time shows.
Say
"Lovely photo. Who taught you how to change the clock on a camera?"
Plot
Out in the corridor, one of the three witnesses asks to speak to me alone.
What are interactive detective stories?
An interactive detective story is a crime novel you solve while it is being written. You read a chapter – a body in the library, a missing painting, a client who lies in her very first sentence – and then you decide what the investigator does next, in your own words. There’s no menu of approved questions and no “search room” button. Ask the butler about his shoes, dust the piano lid for fingerprints, bluff that you’ve already found the letter. The AI writes the next chapter from exactly your move, including the answers you didn’t expect.
That makes StoryZone a creative sandbox for crime stories: investigate as a by-the-book inspector, a rule-bending private eye or the person who should never have been at the scene.
Clues, alibis and a memory for details
A mystery only works if the details hold. The story’s memory keeps track of suspects, alibis, timelines and every lie told in the interrogation room, so a slip in chapter 3 can crack the case in chapter 30. With long-term memory you can look at what the story knows and correct a detail if something got lost along the way.
Good detective moves are specific and a little sly: “I compliment the widow on her roses – and mention, very casually, that someone watered them on the night of the storm.”
From one case to a detective series
Many readers love a recurring investigator. Close a case, then begin a new season with the same detective, an old adversary and a fresh crime, while the story remembers who still owes you a favour. Use Deep mode for slow, atmospheric noir and Action for chases and stand-offs. Mix crime with historical for a gaslit murder mystery, with sci-fi for a case on an orbital station or with supernatural when the only witness is a ghost.

Frequently asked questions
Can I solve the case myself, or is the culprit fixed?
You investigate yourself: question witnesses, search rooms, set traps and accuse whoever you suspect. The truth takes shape from what you find and how you read it, so no two cases end the same way.
Can I play the criminal instead of the detective?
Yes. Be the thief planning the perfect job, the con artist with three identities or the person with something to hide – and try to stay one step ahead of an investigator the AI plays.
What is cosy crime?
Cosy crime keeps the puzzle and leaves out the gore: a village, a cast of eccentric suspects, an amateur sleuth with a day job. In StoryZone you can set exactly that tone – or go for rain-soaked noir. Casual mode keeps it light, Deep mode lets the atmosphere build slowly.
