Instructions
Decide if you will purchase a murder mystery kit or if you are going to create your own. There are many sites, such as Merri Mystery, that offer kits containing the scenario and information to take out the guesswork.
Locate a mystery by searching various books, TV shows, or online sites. Find stories that are interesting and suspenseful. You can use the Hardy Boys or Sherlock Holmes stories or even an episode of CSI to find a murder mystery plot. Choose stories that have as many suspects as those that will participate at the birthday party. You can find mystery books at your local library or visit sites like hulu.com to find episodes of various murder mystery TV shows.
Send out invitations to your guests. Include the details of the game so you don̵7;t have to spend too much time explaining the game at the party.
Select a host/narrator. They will gather the guests together to inform them of the crime, answer any questions they may have, and ensure the evening stays organized.
Recruit a murderer. It is best to have your murderer selected before the party. Make sure they are willing to be secretive so the guests are surprised when the murderer is revealed. They should be playing along at the party by helping to solve the mystery and accusing others of the crime.
Present the crime and details to your guests. Have the crime take place in a different part of the house. You can either recruit a victim to play dead or create an outline of the victim using chalk or masking tape.
Place clues around your crime scene to help your guests solve the mystery. Leave a playing card near the pocket of the deceased to create the assumption that the victim was playing poker or another card game, for example.
Present the clues and solve the crime. Towards the end of the party, meet in a centralized location and allow the guests to explain who they believe the murderer is.
