If you want to play along, you will want to read the host’s guide in full to ensure that you are setting the game up correctly WITHOUT letting you know who the murderer is in this murder mystery party game!
This will depend on (a) the version of party you order and (b) what you/they want to do at the party.
Some murder mystery party game rules say (generally the smaller 6-8 guest and 8-12 guest versions) have the victim rise and become the investigator after their “death.”
Since the victim does not know who murdered them, they can still play along and try to guess the murderer using their previous background knowledge and their money in order to bribe and blackmail others and derive their secrets from one another.
If you have a larger version, and you have not assigned the investigator (they are generally listed as the first person to eliminate for this reason), then the victim will need to become the investigator.
If you have assigned the investigator, but have an extra role that is not already filled, the victim can become this person (if you order the 20-80 player version, this will always be an option).
If the victim wishes to do nothing, they can do that as well. Some guests really enjoy playing along “dead” and trying to figure out who killed them.
