Murder Mystery Synopsis:

It is almost time for the International CSI Association conference in the lovely city of Anonville. The who’s who of the forensic world is already trickling into the Grande Resort & Hotel. The crème de la crème of forensic investigators will present their exciting and innovative forensic science research projects to their colleagues, followed by the traditional social hour where a delectable buffet-style dinner will be served. The forensic investigators from around the globe will relax, enjoy good food and catch up on the past year’s research findings. They’ll be sure to discuss their big cases and trade interesting stories from the crime scenes they’ve investigated over the past year.

It’s well known that some of these investigators have a turbulent history and have not always gotten along harmoniously. Social media outlets have been peppered with posts of ill intent, and scandals are brewing at the surface. However, the event hosts are in good spirits about the conference and believe the CSI personnel will remain professional and the conference will go off without a hitch. They may be dreaming. Many think there may be enough fuel added to the fire for a public eruption by putting these people in the same room. You’ve got your itinerary and are set to arrive at the Grande Resort & Hotel tomorrow morning. This is where your story begins.

    What would Horatio do?

    I hosted this in June 2021 (thankfully lockdown was over), hired a Conference room and got friends and family together - using expansion packs too. It was my first time hosting and guests participated at varying levels of enthusiasm and gusto. A fun night was had by all.

    Great game to play, teen group had fun with it

    Posted by Joshua Hebert on Feb 28th 2022

    We played this one over the weekend for my daughter’s birthday and with her group of friends. In all we had 12 characters played and all were around the 16-17 age range. Everyone had a great time and the party was a huge success. Now, I do have some recommendations for others thinking about trying this. Please please please, if you are thinking of hosting one and you and the group is not very familiar with how to play these then I HIGHLY recommend you have someone (adult preferred) to be the actual Host and not try to play a character. Too much is going on that things can get a little jumbled. This is especially true if you are playing the host and don’t want to spoil the story of who the victim is. We had an issues where the victim just didn’t understand the timing and what they were supposed to do and ending up dying way too earlier and in the wrong place. It would have been better if the host (not playing a character) could have been there to make sure that it played out correctly. It made for some interesting story corrections that had to be done. It also helps to know that ppl can have someone to go to ask questions if they are confused about something. Even still though we all had a great time.

    This was our first time hosting a Murder Mystery Dinner. The guests had a great time. I being the host, tried to participate not knowing the details (had hubby stuff envelopes). I strongly suggest dressing up and committing. I know if we do another one, we will know what to expect / how to play so it will be even more fun!

    Super fun and flexible

    Posted by Unknown on Apr 20th 2018

    Played with group of 14 20 year olds, everyone had so much fun and got into character. Great flexibility to be able to add and take players for no shows etc. Only bad thing is always the same murderer so can't play again with same bunch.

    Save money and print from home or have them do the work for you!

    Posted by Terri Andrews on Oct 13th 2017

    I LOVE that this product has two options for purchase. I bought the kit for my son's birthday party and chose to do the work myself, which was a huge savings. But I can see myself purchasing a kit in the future for a party for friends, and buying the complete package. I would highly recommend the product AND the website. There is SO much information available to make the party a success. I love it!

    Super fun!

    Posted by Becky on Jun 5th 2017

    I bought this murder mystery for my daughter's 13th birthday party with CSI theme. I had 14 girls and they had a blast! I was surprised how much they got into it, stayed in role, and worked hard to find the murderer! They had so much fun!!! The directions were easy to follow and I had fun getting everything set up. I would highly recommend this for a fun party !

    We enjoyed it!

    A group of 12 played this game at my home and we all had such a good time, we are already planning the next. My advice is to get the optional props (tshirt, halo, makeup, etc.) because it is so funny to decorate your victim!
