    Archibald Grim was a coldhearted miser who despised everyone in the town of Graymire. A greedy recluse, Mr. Grim only left his castle for his lucrative job as the president of First National Bank. Archibald spent his life hoarding his wealth and spewing hatred, sorrow, and despair across the city.  It was no surprise when Archibald Grim's body was found by his housekeeper this morning.  It appears that someone has slipped the chap a bit of poison.  The burning question is - who is guilty?  Is the killer an employee of the bank? A former colleague? His butler? Or might it be a family member who wants an inheritance?  The Graymire police have listed you as a suspect in the murder of Archibald Grim. You must journey to the Grim Castle at the exact time on the notice that was sent to your home. It would be dangerous not to attend, as the police might consider your absence a confession. This is where your story begins.

    1. Great product, easy instructions for host

      We did the online download (did not send paper invitations, printed our own name tags, etc.) to save money. This was perfectly fine and did not take away from the party. Our daughter is 12, and we had a total of 10 tweens over for an Archibald Grim murder mystery party instead of a traditional Halloween party. These are very sharp kids, and only 2 of the 10 figured out who the murderer was, so it was sufficiently challenging. I also made a photo booth using a gold "streamer" background and some Sherlock Holmes props from Amazon, and that was was a huge hit. I told the kids their costumes had to all be borrowed items or something from Goodwill, that they didn't need to go out and spend a lot of money. They could have made it easy and done so, but this gave them the challenge of being creative. I look forward to finding an excuse to do another mymysteryparty event! on Dec 17th 2019

    2. Great product

      I hosted a murder mystery luncheon for my Girl Scouts and their moms. We had so much fun. They loved dressing up. All the directions and materials were very easy and made for a very enjoyable time. My daughter now wants to do one for her birthday party. on May 3rd 2019

    3. 13 year old theatre kids? It's a hit!

      Hosted almost a dozen seventh graders for our son's birthday party this weekend, and Archibald Grim was awesome! Easy to run with the materials in the downloadable PDF, and we're definitely excited to do it again! on Feb 25th 2019

    4. Great fun for 11/12 year old girl's birthday party

      The girls had a ball playing this game. They were very excited in advance of the party to arrange their costumes and become their characters. During Round 1 they got the feel of the game, and by Round 2 they were seriously collaborating evidence and invested in discovering the murderer. They jumped on new evidence as it came in: the scavenger hunt for Grim's decoder and the forensic analysis report were devoured with excitement. By Round 3, they were all eager to announce their pick for murderer and explain why. The excitement was palpable as each character discovered her innocence and finally, one discovered her guilt. Age 11/12 was perfect for this game. The birthday girl's sisters ages 10 and 8 were enthused during round 1, but their interest gradually waned because some of the vocabulary had to be explained to them and it was tough for them to understand some plot and character elements. We decorated one room with a "chalk outline" of the deceased using 1 inch white electrical tape and placed a "spilled" coffee cup next to it. The room was blocked off with yellow and black caution tape. The dining room was set for a formal dinner and the centerpiece was two candle sticks and piles of chocolate gold coins. Because the game was downloaded, the images, invitations, and information could all be edited for our particular needs. We would recommend this game! on Feb 25th 2019
