For my work's Christmas Party this year, Dr. Brown (my boss) planned a Murder/Mystery themed party at his house. We found out about it a few weeks ago, and have had time to get to know our character, that no one else knows about, and to put our costume together.
The party takes place on a cruise ship. We (both passengers and crew) are all at the Captain's Cocktail party when a murder takes place. There are many side issues going on that cause everyone to blame each other. At the end of the night we had to try and figure out who the killer was.
I was one of 3 final beauty pageants, trying to win the title of Ambassadress.
Sam was the Head Barman, known as Tom Collins, and was actually my husband on the ship although NO ONE knew this since my romantic involvement with him would eliminate me from the competition due to the pageant rules. There was one person however, that knew I was married, but was using that information as black male.
We had 16 players (8 staff and their spouses.)
We each had a sheet of paper that had our objectives on it. After everyone seemed to have taken care of their objectives, the lights went out mysteriously, there was a scream, and when the lights came back on, the "Showgirl" was found dead on the floor. (Good acting by the way Mandi!)
We had a lot of fun the whole night acting like people we weren't and would never plan on being!

At the end of the night, the truth came out that I, "Kristy Marie" was indeed the killer. I had to kill the showgirl since she knew of my marriage to Tom Collins, and I couldn't afford for anyone to find out, or I would be eliminated from the Beauty Pageant. I mean come on, can you blame me? :)
