You've been murdered! Well, almost, you're not dead yet, so you want to communicate the identity of who the killer is, but you have a limited number of tools to make that happen: a small number of cards with obscure marks on them and...yourself. Yes, your dying body. Maybe you can arrange the cards in some manner to convey information. Maybe your still fingers can point to — or obscure — parts of the cards to increase the clarity of your dying thought.
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.
