Mystery Synopsis:

The maximum security unit of the Bloodstone Sanitarium is where defendants declared not guilty by reason of insanity are transported after their murder trial. These patients end up spending a majority of their time in isolation since they often threaten bodily harm to others.

Nonetheless, the hospital administrator of the Bloodstone Sanitarium has decided to host a Halloween party for this unit to prove to the city government there are no longer problems with this facility. In recent news stories, there have been reports of missing patients, injuries to medical staff, as well as an escapee who rampaged the town of Gothenburg.

The patients of the maximum security unit are thrilled about the celebration, but the staff members are dreading the event but do not have a choice but to attend if they wish to keep their jobs. This is where your story begins.

    Our family did this murder mystery for my daughters birthday. It was much fun and one person figured it out! I highly recommend. The directions are fantastic and easy to follow. Will definitely be doing another.
