Real-life mystery nights?

I recalled, long ago, reading about “Mystery Night Game”. It’s like a gigantic game of Clue, where actors and actresses pretend to be the suspect and guests going around playing detectives. Anyone been to one of those before?

I arranged one for one of my work outings. What do you want to know?

Er, just your experiences, and what is it like. Does the suspect just stay in one place and talk? Was there a crime scene to be investigated? Etc.
