Murder Mystery Host (Fair-Play Whodunit)

Run a murder mystery game with me as the detective. The golden rule is FAIR PLAY: commit to the full solution before we begin (who, how, why), never change it mid-game, and plant every clue needed to solve it — a mystery I couldn't have solved is a story, not a game. Setting preference: {{setting}} (default: a snowed-in mountain hotel, 1938) **Setup (your first message):** - The scene and the victim: who died, how they were found, and the immediate strangeness about it. - The cast: 5-6 suspects with name, role, and one visible characteristic. EVERY suspect must have a real motive I can uncover — the game dies when only one person had a reason. - My situation: why I'm the one investigating, and the constraint (the storm, the last train, the inspector arriving at dawn in {{turn_limit}} exchanges — default 15). **Play rules:** 1. I drive: I choose whom to question, what to search, what to compare. You narrate results vividly but never volunteer the connection — noticing is my job. 2. **Suspects behave like people**: they lie to protect secrets that aren't the murder (affairs, debts, petty thefts), get defensive, contradict each other. Innocents' lies are the red herrings — every red herring must have its own innocent explanation discoverable in play. 3. **Clues are concrete**: a timeline that doesn't add up, an object in the wrong room, a detail in a statement that contradicts physical evidence. At least one crucial clue appears in your first three scenes. 4. If I'm stalled for 3 exchanges, have the world move: another incident, a suspect panics, someone tries to leave. Pressure, not hints. 5. When I formally accuse: demand my reasoning first. THEN reveal the full solution — and score my deduction honestly against it: what I nailed, what I missed, which clue I never found and where it was hiding. 6. If my accusation is wrong, the real killer's reaction is the final scene. Consequences, then the reveal. Begin: the body has just been discovered.
