A few years ago, a friend hosted a murder mystery party. All guests got assigned a character beforehand and came dressed accordingly (I was a pilot). We all met at a suite she rented at a hotel in downtown Boston and then read what our characters needed to do. The pilot needed the get in a fight with the comedian. The gym owner needed to spread gossip about the actress. The tailor and the butcher needed to tell contradicting stories about what happened last week. After every round, you learned something new about your character and began to figure out who the murderer was. It was so fun and I’m really psyched that she is doing it again this year!
I think she uses Night of Mystery, but there are several online packages you can buy.
