See how a typical Night of Mystery party unfolds.

How it Works

No experience? No problem. Night of Mystery parties are specifically designed with first-time hosts in mind. Everything is laid out step-by-step—from invitations to party flow—so you’ll always know exactly what to do next.

Most hosts are surprised by how easy it is to run—and how quickly guests get into character and take over the fun. You can even play along as a character if you’d like! Just review the host guide ahead of time, follow the simple instructions, and then sit back and enjoy watching the mystery unfold.

Excellent Question! And one that needs more explaining, please see the “How to Play” Page of our site and/or download a preview file to get a complete understanding of how our mysteries are run!

Absolutely. We make it easy with two types of downloadable invites:

Before you purchase:
Use our RSVP invitations to invite guests and confirm your headcount (we highly recommend this step!)

After you purchase:
You’ll receive email-ready invitations that include each guest’s character description, so you can assign roles and send everything out in just a few clicks.

YES! As host, you get to decide how much or little you know about the murder.

If you want to play along, you will want to read the host’s guide in full to ensure that you are setting the game up correctly WITHOUT letting you know who the murderer is in this murder mystery party game!

In most Night of Mystery parties, the victim doesn’t sit out—they become the investigator for the second half of the game!

Since the victim doesn’t know who killed them, they can jump right back into the action—questioning suspects, gathering clues, and trying to solve their own murder.

Testimonials

“I purchased the Night Of Mystery packet for a work team building event. All of my co-workers said it was the best team event they've been to. The packet was very straightforward and had so many ideas and tips to help make running the event super simple. Highly recommend!”

Christine Benoit

“I hosted my first party and I was scared that if anyone could fail such a flawless package it would be myself. But this kit makes it so easy and fun. Lots of room to make it your own and not cookie cutter, but always super straight forward! I can't wait to host another one!!! Thanks Night of Mystery!”

Elyzabeth Wolfe

“I've had three parties over the years. This year we will be doing it again! Normal parties have their groups. High school over there, church over there, family over there. Well with the murder mystery dinner there is none of that. Plus you're free to not be "you" for the night. Every party has been a success! Last one, we had over 100 people come.”

Jeremy McLaughlin

“This was the BEST team event we’ve ever done. It was inclusive, creative, and so easy to execute with your kit. Everyone had a blast!”
