I've been considering doing a murder mystery Halloween party this year. The one in particular that I'm looking at is called "Death of a Vampire". I think this would be a fun theme to do. The game is for up to 14 players. My question for those that have done these type of parties is can the extra guests still help solve the mystery if I have more guests than is required to play? I'm sure some guests will not want to play a character, but I would like for them to be able to at least participate. Thanks!
