How to Run a Murder Mystery Dinner
A mystery dinner is an information game hosted around a meal. Agree on tone and subject matter before invitations go out. If a fictional death is unsuitable for the group, the same evidence structure can concern a missing object.
Write the solution first
Decide who acted, what happened, when and why. Build an evidence ledger showing which clue supports each conclusion. Red herrings need an eventual explanation rather than a contradiction.
Distribute knowledge fairly
Every group should receive core evidence needed to solve the case. Private secrets can add conversation, but the solution must not depend on one absent guest volunteering a hidden fact.
Release clues between courses
Give the host exact cues and a visible discussion timer. Leave eating and movement time out of clue reading. Provide large-print or spoken versions when needed.
Vote, then explain
Collect one accusation and a reason from each group. Reveal how the evidence fits the solution and which tempting alternative it rules out. Thank participants without shaming incorrect guesses.
Worked example
Fictional worked example: eight diners investigate an observatory key moved without permission. A repair note authorizes the courier to collect it at 18:10. A gate log places the courier at the workshop at 18:15; a photograph shows the astronomer was still at the banquet. Guests receive the note after the first course and the log after the main course. The reveal distinguishes moving the key from stealing it. Two observer guests hold public timeline sheets, so declining acting does not break the case.
Common mistakes and execution notes
Do not invent a new culprit during the reveal. Avoid requiring lies about essential public evidence. Tell guests whether fictional conflict is allowed and give them a simple way to step out of role.

Can the host play?
A host who knows the solution should facilitate rather than compete for solving points.
