Create an original murder mystery party game for [number] players, about [90] minutes. Setting: [era and place, e.g. a 1920s lakeside hotel during a storm]. Tone: [e.g. funny, light, family-friendly; no graphic violence].

Include:
1. The premise to read aloud (under 150 words).
2. One character per player: name, public description, costume idea, a secret, a goal for the evening, and what they know about two other characters.
3. The victim and how they were found (non-graphic).
4. Three rounds of clues, each clue tied to a character who reveals it.
5. The solution: who did it, how, and why, plus the chain of clues that proves it. Every clue needed must appear in the rounds.
6. A one-page host guide with timings.

Make sure at least two characters look suspicious and that the culprit is deducible, not random.

Replace everything in [square brackets] with your own details.

Settings & parameters

• Any capable chat model; ask for the character briefs as separate sections you can print one per page

Variations

• Remote version: clues revealed as messages in a group chat.
• Kids' "missing cake" mystery with no crime.

Tips

• Read the solution first and check every needed clue appears in the rounds before the party.
• Keep characters original rather than borrowing from famous detective stories.
