Murder Mystery Synopsis:

‘Tis the season for Drew Beasley to host the annual bash at the Harrison House. Excitement is hanging thickly in the air, as the VIPs of Pandora City gear up to mingle with friends, colleagues, and of course - unavoidable foes. Drew Beasley, the CFO of the Harrison House, firmly believes that building community spirit around the Harrison House is the only way to keep the historical bed & breakfast alive. However, it is becoming increasingly difficult for the townspeople of Pandora City to remain harmonious in the same place for too long of a time. Drew and the staff of the Harrison House have taken extreme measures this year to divert the guests’ attention away from each other and toward the party’s festivities.

They have planned a delectable menu, fun party games and of course, spirited music for the guests to enjoy. This might be their last shot at hosting a successful shindig, as the heir to the Harrison estate is growing tired of the way the Harrison House is being managed. Hopefully, the staff can prove that the annual bash is a necessity for the Harrison House’s ultimate success. Without the yearly buzz as a reminder, the townspeople could forget about the Harrison House even though it has been in Pandora City for over 100 years.

    We used this for our company and it was SO much fun! The game was perfectly organized and explained well enough for 46 people to play easily. I definitely recommend getting this if you need one for a big party!
