Murder Mystery Spooky Synopsis

The cast members of the Chamber of Screams Haunted House worked really hard this Halloween season scaring the people of the town. The management of the Chamber of Screams has decided to reward the employees with a mini-Halloween celebration held during normal business hours in the employee break room. As you are well aware, the Chamber of Screams Haunted House typically shuts down each night for a brief time period so the employees can get a break and straighten up the haunted scenes. You heard a rumor when you first started working there that the management probably does this so the line of customers outside will build up and The Chamber of Screams will look twice as busy and much more popular. Regardless of the reason for this break, you definitely look forward to the upcoming treat during your next shift at work. This is where your story begins.

If you are not hosting this as a private event, you might need a commercial license.

    We ran this murder mystery for a group of Girl Scouts and they had a blast! Watching them go from questioning each other to working together to solve the murder was great.

    Perfect scenario for Halloween

    Posted by Lauren on Nov 12th 2019

    The game was great and everyone was happy to be in character, even without knowing what to expect. Quite easy to set up too. It was great and everyone discussed the clues and was very into it to understand the story together and to get all the clues to uncover the mystery. Only downside, some people I believe felt like there was a bit too much reading at the start of each round, which slowed down the dynamic a little bit.
