The Deadline, 23:00 | Japanese-Style Murder Mystery for 3-6 Players + Host | Printable PDF | 90-120 min

THE DEADLINE, 23:00 — a Japanese-style murder mystery for 3 players and 1 host. 90–120 minutes. Printable PDF.

Tonight at 23:00, a novel goes to print. At 21:50, its author is found dead in the meeting room of her publishing house.

The clues are galley proofs with red ink. Two pages torn out. A fax log from the printing plant. The colophon of a small-press book published eight years ago.

Every piece of evidence in this game is a document the players read. There is nothing to cut out and nothing to assemble. It prints in black and white on ordinary paper, and it runs just as well over a video call as around a table.

WHY IT WORKS AS A CLASSROOM ACTIVITY

• Close reading with stakes. Every clue is a text students must read carefully. Missing one detail changes who they accuse.
• Evidence-based argument. Players have to make a claim, cite the document it came from, and defend it against three other readings.
• Structured discussion. Fixed phases — reading, discussion, investigation, final discussion, vote — so the conversation does not drift.
• No preparation beyond printing. The host script is written to be read from the top. No rules to adjudicate, no dice, no components.

HOW THIS DIFFERS FROM A MURDER MYSTERY PARTY KIT

If you have run a boxed “murder mystery dinner” before, this is a different genre. Please read this before buying.

• The host does not play. They run the game. That is what lets the story hide information the way it does.
• Each player gets a private booklet with a secret only they know, and two win conditions — one shared (find the killer) and one private.
• One of the three players is the killer, and that player is a real player with their own goals.
• Single use. Once you know the answer you cannot play it again — but you can host it for other groups afterwards, as often as you like.

WHAT YOU GET (7 files: PDF + TXT)

• Read Me First — 4 pages, for everyone
• Host Script — 8 pages, host only. Running order, read-aloud text, timing, and what to do if the table stalls
• Evidence Set — 12 clues, 5 pages, host only
• Three character booklets — 4–5 pages each
• Plain-text version — paste-ready for a video call or a shared document

WHAT YOU NEED

Four people (1 host + 3 players), 90–120 minutes, and either a printer or a shared screen. First-time hosts can run this.

HOW THIS WAS MADE

This scenario was written with the assistance of an AI language model (Claude, by Anthropic), then edited, structured, and consistency-checked by a human before release. The plot, characters, clue structure, and all text were reviewed by the maker.

Ai-Q Labs makes murder mysteries in which all the evidence is text. Eleven scenarios, for 2 to 8 players. Check out Ai-Q Labs for the rest of the series.
