Murder Mystery Synopsis:

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

    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.
