Why Holiday Murder Mysteries Are a Perfect Match

Hosting a murder mystery is fun any time of year, but holidays provide a unique backdrop:

• Built-In Atmosphere – Holidays come with their own color palettes, decorations, and traditions you can easily adapt.

• Seasonal Gatherings – People naturally come together for the holidays, making it easier to get a group of players.

• Tradition with a Twist – Hosting a themed mystery can become an annual tradition that grows more elaborate each year.
