Format
In each episode's prologue, the cast learns the crime setup and chooses roles—detective or suspect. Suspects get detailed backstories and can withhold info unless questioned; only the keyman can lie. Gold keys are given in advance—correctly identifying the keyman lets players keep their key; wrong guesses must return it.- Alibi: Each player introduces their suspect character, shares their connection to the victim, and explains their whereabouts before, during, and after the crime.
- On-Site Investigation: Players are split into three teams and given ten minutes to investigate the crime scene. Each has a phone and may take up to ten photos.
- Briefing: Players present their collected evidence and may question others about it. Afterward, each states who they currently believe is the keyman.
- First Keyman Vote: After hearing each player’s briefing, the detective secretly casts a vote on who they suspect is the keyman.
- Additional On-Site Investigation: Players gather at the crime scene for group discussion, held alongside the 1-on-1 Interrogation.
- 1-on-1 Interrogation: The innocent detective summons players for further questioning.
- Final Keyman Vote: After interrogations, players give final statements and the detective debriefs. Following 5 minutes of investigation, players secretly vote for the keyman. The most-voted player is arrested. Correct voters keep gold keys; detectives who guess right twice earn two keys, and suspects who avoid detection earn one.
