First Light, 03:00 | Japanese-Style Murder Mystery for 3-6 Players + Host | Printable PDF | 90-120 min

FIRST LIGHT, 03:00 — a Japanese-style murder mystery for 3–6 players and 1 host. 90–120 minutes. Printable PDF.

Mount Fuji, the eighth station. Three thousand metres up, three days before the mountain closes for the year. A small hut called Kumokiri. That is all of it.

Tonight there are three people staying. Three, and one more. Kyoichiro Hayami, forty-seven, a mountain photographer. Twenty-five years ago he photographed the dawn from above this hut, and that one picture made his name. He has come back on the same date every year since.

Next month a book collects all twenty-five years of it. He has written the afterword, and tonight he means to let the other three read it.

At 22:40 a thunderstorm settles on the eighth station. The trail closes above and below. The call is made. But no rescue team can move until the sun is up.

At 03:00 he is found dead on the rocks, twenty metres below the camera platform.

The wind is over twenty metres a second. Nobody heard anything.

First light is at 05:12. The rescue team is due at 06:30. Until then, there are three of you in this hut.

There is no vote in this game

In most murder mysteries everyone votes at the end to name the killer. Not here. Here you decide whose camera takes the last photograph.

• The tripod survived. There are three cameras in the hut, and before 05:12 there is time for exactly one frame
• The three of you talk and choose one camera
• Whoever presses the shutter is the one who tells the rescue team about tonight
• Which camera you choose decides what survives of the story — three endings, all of them real

If 05:12 arrives with no agreement, nobody takes the picture. The tripod stands there and morning comes. That is not a failure. It is one of the proper endings.

This is not an ending where you catch a killer. You can name the killer or fail to; the story finishes either way. What you are deciding is which version of a twenty-five-year-old night reaches the world.

WHY IT WORKS AS A CLASSROOM ACTIVITY

• Close reading with stakes. Every clue is a document students have to read carefully. Missing one detail changes who they accuse.
• Evidence-based argument. Players make a claim, cite the document it came from, and defend it against the other readings at the table.
• Structured discussion. Fixed phases — reading, discussion, investigation, final discussion, resolution — 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 to assemble.

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 goals — one shared with the table, one private.
• The culprit is a player, not the host, with their own goals to pursue.
• Single use. Once a group knows the answer they cannot play it again — but you can run it for new groups as often as you like.

WHAT YOU GET (8 files, 7 of them PDF)

A read-me for everyone, a host script with the full running order and read-aloud text, the evidence set, one private booklet per character, and a plain-text version you can paste into a video call or a shared document.

WHAT YOU NEED

3–6 players plus one host, 90–120 minutes, and either a printer or a shared screen. First-time hosts can run this. Everything prints in black and white on ordinary paper.

CONTENT NOTES

Deals with a fall and with a death twenty-five years earlier. No gore or violence is depicted. The hut, the characters and the photography prize in this scenario are fictional. Suitable for high school and adult groups.

LICENSE

Classroom and club use is fine, including running it for as many groups as you like. Streaming and let’s-plays are allowed, monetized or not. Please do not redistribute or resell the files, claim authorship, or post the solution publicly.

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 — a corrected page proof, a radio log, a weather record. Check out Ai-Q Labs for the rest of the series.
