Murder Mystery Synopsis:

Patty O' Brian's Pub is smack dab in the heart of Dublin. This hopping hotspot is famous for putting on to-die-for celebrations. The highly-anticipated annual St. Patrick's Day bash is drawing near, and it's almost time to bring out your inner leprechaun and enjoy delicious Irish offerings while partying with the most prominent, beloved, and trendy townsfolk.
However, you should proceed with caution at the gathering. Scandals, feuds, and mayhem plagued the last year like no other. People who didn't have a mean bone in their body have become some of the most ruthless, vengeful souls you've ever known. Nevertheless, the pub management expects everyone to cast aside their differences - if only for one enjoyable evening. Then, if all attendees comply, everyone might be safe at the party. You have your ticket to the celebration, and this is where your story begins.

    We had 20 playing that were assigned characters (we purchased the expansion pack). We had 8 additional adults/teens that didn't want to play but wanted to watch. We also had several children present that we let dress up as members of the Midnight Heros, Dublin Greasers, or Riverdance Dance Crew (The Crazy Clovers - lead by non other than the legendary Murphy O'Sullivan). At first, we were a bit concerned because of the # of people playing. We've done a couple of smaller (10) mystery parties by other companies in the past, and they were a bit chaotic and hard to follow. This one was laid out wonderfully. The directions were very easy to follow. I did the download and print package. The pre-game activities really helped get everyone excited. I loved that we were all able to mingle about as we would at a real party. We decorated the house to look like a pub, and I made a Paddy O'Brian's sign to put at the entrance to our house. I was impressed at how well everyone stayed in character throughout the night. They would even request a couple of extra minutes between rounds to "go ask another question" of another character. We actually ate while everyone walked around and talked during the first round. That worked well for us. If you want to take lots of pics and video, I wouldn't suggest playing a character. It's hard to focus on both. This was a great product, and we will defintely be using this site again.

    We were 10 people and it was everybody’s first time doing a Murder Mystery. As the host, I also played along. It was a great game and very easy to follow. Half of the group guessed who the Murderer was. We all had fun!!
