Five cases. Six suspects each. The killer is chosen fresh every time you play, and at least one person in the room is lying about who they are. Solve it together, accuse separately.
Same case, different killer, different lies, every single time.
Raised Curious
Evidence tells you what the killer is. The dossiers tell you what each suspect claims to be. Dashed blue tags are unverified claims. Spend an Insight to check one. When the evidence and a dossier match on every point, you have your killer. Unless they lied.
No conferring from here. Each of you picks alone. You can be right together, wrong together, or one of you can be insufferable about it for a week.
