Murder Mystery Synopsis:
Dr. Doom is the heir of the Doom estate and a chemist made famous for formulations of harmful pesticides. The former scientist has led a troublesome life full of misery, lies, and deceitful practices. Reflecting upon the past, Dr. Doom decided to host a dinner at the Doom Mansion in hopes of resolving the differences with those wronged in the past. Most of the guests have accepted the humble invitation and are excited to enjoy a night of fine dining, games, and good conversation.
Dr. Doom also has plans to unveil a priceless diamond pterodactyl egg – a family heirloom which has been touted in the newspapers for many years. You’ve been invited to the luxurious affair, and this is where your story begins.

Played it with the youngest player Age 8 and it was great
Loved the story and the easy to follow instructions for every round. We were pleased to find that it was easy to play. Everyone got into character and some people were confused because the acting was so great!

Be prepared for your players to get creative
This. Was. A. Hoot. Our family revealed untold acting chops, and the hilarious trash talking flowed, from the pregame texts and emails to the actual game day. Playing with a couple of tweens, young adults in their twenties and older adults up to age 70 was a fun and unique mix, and this was perfect for a non-Halloween autumn game night - it gave us an extra excuse to dress up. The amount of cutting things out and host/hostess planning was entirely doable (give yourself some time, though - think in terms of a week or two beforehand, if you can), and while this was our first time, we know it will certainly not be the last (especially because we were hardly done with this one before people wanted to know what we were doing "next time").

Diamond thievery mystery party
We did this dinner party mystery with our 8 grandchildren ages 11-17. It was nice to have a choice of an event that did not involve a murder. It was a fun evening.

The Daunting Diamond Thievery at the Old Doom Mansion
We had a great time with this party. We did this at a family get together. I was the hostess but also acted a character without knowing the solution. The kit is well put together and can easily be adapted for many different situations. You can make it as simple or elaborate as you would like. Everyone had a wonderful time. I highly recommend this product. If you are hosting and also acting, I recommend a menu that can be prepared in advance if you are planning an actual meal. This will give you more time to mingle with your guests in character. We are already planning on doing another one at our next family get together.
