Setup and Launch

Gather four to eight performers. Use an open stage for group scenes and individual interrogations. Ask the audience for suggestions: an occasion for the gathering (a party, a funeral, a class reunion), character names or traits, possible motives, who the victim will be, and a weapon or clue. You can also prepare a rough outline or character list in advance. Assign one or two performers as detectives; the rest play suspects. Before you start, lay down the ground rules: every suspect must build a vivid character with a clear motive, deny their own guilt while suspecting others, and use flashbacks — short scenes from the past — to surface new facts.

Flow

1. The Gathering

Performers enter in character and interact at the event, establishing relationships and hinting at possible motives. Weave audience suggestions into dialogue and connections. Let suspicion and tension build gradually — side-eye glances, loaded comments, someone stepping away from the group at just the wrong moment.

2. The Murder

At a chosen moment the lights cut out (or the blackout is mimed with a gesture). When the lights return, one character is found dead — played out dramatically or simply declared. The detectives step forward and take charge.

3. Interrogations

The detective questions each suspect one at a time, though others may barge in to defend themselves or accuse someone else. During questioning, suspects act shifty, deny involvement, and try to redirect suspicion. Flashbacks are played out as short scenes — a whispered argument before the party, a borrowed knife returned too quickly. Everyone must track the shared timeline and established facts so the story stays airtight.

4. Resolution and Reveal

Once all suspects have been questioned, the detective gathers everyone in a single room — Hercule Poirot style — and walks through each suspect's motive. The last suspect discussed is tagged as the killer. Lights go out. The opening scene replays. Lights come up again, and the audience finally sees the murder happen in slow motion, performed by the now-revealed killer. The conclusion must feel logical and rooted in the clues planted throughout the show.

Key rules

  • Build a vivid character — Every suspect needs distinct traits, a backstory, and a clear motive from the very start. The audience should be able to name your character and your reason to kill within minutes of the gathering.

  • Deny guilt, redirect suspicion — Always deny your own involvement, but actively point the finger at others. This keeps the mystery alive and the tension high. If nobody is accusing anyone, the detective has nothing to work with.

  • Yes-and the audience suggestions — Accept and weave the victim, weapon, and clue into the story so the audience sees their ideas driving the plot. Drop a callback to the audience's weapon choice mid-interrogation — they will love it.

  • Use flashbacks actively — Play out key moments as short scenes during interrogations to make motives and alibis visible. A flashback of two characters arguing over money is worth more than a verbal explanation. Keep each one tight — 30 seconds, one reveal.

  • Escalate suspicion gradually — Start with hints and loaded glances, then build toward outright accusations. If the killer is obvious in the first five minutes, the investigation has nowhere to go.

  • Group mind on the timeline — All performers must track shared events and established facts. If one suspect says the argument happened at 9 PM, nobody else can claim it was midnight. One contradiction and the audience stops trusting the story.

  • Interject with purpose — Suspects not currently being questioned may cut in to defend themselves or throw someone else under the bus. Time these interruptions to raise the stakes — not just to get stage time.

  • End with an honest reveal — All clues must lead logically to the killer. The Poirot-style finale where the detective walks through each suspect's motive should feel like puzzle pieces clicking together, not a random pick.
