FAQ
What sort of venue do I need?
Because murder mysteries involve playing games and your guests doing lots of fun and silly things, they need a quiet venue with lots of space.
You can hold a murder mystery at home or in a function venue. Try any venue which:
- Is completely private i.e.: not a restaurant or public spaces.
- Is very quiet i.e. no bands, piped music or DJ's next door.
- Has lots of room to move around. Imagine all your guests standing in a circle.
- You need one central area big enough for all guests at one time.
