If the clues are easy to understand, they will be destroyed by the culprit; if they are difficult, they will not be communicated to anyone, and your death will not be avenged, so leave an exquisite dying message.
The other players in Dying Message are detectives, and they make inferences based on the limited information available. Detectives can co-operate or confront one another, and whether the deduction turns out to be good or bad will depend upon their discussion.
Note: The designer states that this game is for 3-8 players, not 2-8.
