Murder at Gravestone Manor- A Roaring Twenties Murder Mystery Dinner for 10 Guests
The best approach is to send each player their character sheet 7–10 days before the event. That gives people enough time to think about their character, organise their costume, and arrive already knowing their secrets and motives.
Do NOT send a reveal of the murderer, other characters' secrets or the clue timeline.
Only Chester receives the murderer information.
A good structure is:
Before the event: Send each guest only their own character sheet.
Arrival: Everyone receives a name card and remains in character.
Pre dinner drinks: Introduction and rules are read aloud.
Course 1: First round of clues is revealed.
Course 2: Additional clues and riddles are revealed.
Dessert: Open accusations and final voting.
Finale: Murderer reveals themselves and explains the crime.
The host should ideally not be a player. Instead, they act as narrator and clue-master. If the host must play, simply make them a non-suspect narrator character.
Introduction and Rules (To Be Read Aloud)
Welcome, ladies and gentlemen, to Gravestone Manor, the most extravagant estate on Long Island. It’s the summer of 1928. Jazz is hot, prohibition is cold, and fortunes are being made as quickly as they're lost.
Tonight, millionaire and host, Reginald Gravestone, has invited eight of his closest associates to celebrate the unveiling of his newest investment venture. The champagne is flowing, the gramophone is playing, and everyone is having a splendid time......until the lights suddenly go out and a scream echoes through the ballroom.
When the lights return, Reginald Gravestone lies dead beside the grand staircase, clutching a torn piece of paper.
The police are delayed by a bridge closure, meaning everyone in the manor is trapped together until morning.
One of you is a murderer. The rest must discover who.
1. Stay in character as much as possible.
2. Reveal information about yourself gradually throughout dinner.
3. You may lie about your suspicions, but you may not invent facts not listed in your character sheet.
4. At the end of dinner, each player will accuse one person.
5. After all accusations are made, the murderer reveals themselves.
6. The winner is the player who correctly identifies the murderer and can explain why.
