Detective Notebook Template for Murder Mystery Games
Published June 14, 2026 · 1 min read
A detective notebook does not need to be beautiful. It needs to stop your brain from mixing up suspects, times, motives, and clues. In a murder mystery game, good notes are often the difference between a confident accusation and a guess.
Use this simple template for online cases, party kits, and solo detective games.
Page 1: Case basics
Write this before questioning anyone:
- Victim:
- Location:
- Time of death or last known alive:
- Main question:
- Suspects:
- Important rooms or objects:
This keeps the investigation grounded when the story gets messy.
Page 2: Suspect grid
Create a row for each suspect:
| Suspect | Alibi | Motive | Opportunity | Contradiction |
|---|---|---|---|---|
| Name | Where they say they were | Why they might lie | Could they do it? | What does not fit? |
Update the grid after every major clue. Do not wait until the end.
Page 3: Timeline
Most killers hide in time gaps. Keep a clean timeline:
- Victim last seen.
- Key movement.
- Noise, message, or discovery.
- Object moved.
- Body found.
If two statements cannot both fit the timeline, mark them with a star.
Page 4: Evidence
For each clue, write what it proves, not just what it is. "Broken glass" is less useful than "someone entered after the room was supposedly locked."
Final accusation checklist
Before accusing, confirm:
- I can name the killer.
- I can explain the method.
- I can explain the motive.
- I can place the killer at the scene.
- I can account for the strongest red herring.
