It went straight into a performance CheapSausagesAndSpam. We had all seated in the dining room and all around us things were going on - the theme was a murder at an awards ceremony so all around us were 'agents' and 'stars'. We had to be really observant because there was no formal introduction that the night had started.
There were some more performance type bits but even then you had to watch for the interactions between the other actors who weren't central for clues.
During the meal actors moved around the tables still in role making little comments and conversation which added more clues. There were also boards around the room with little bits of information on them in case you missed things which might be significant (or not!).
At the end we all filled out who we thought and why and there was some idea sharing from each table before the 'killer' and their motive was announced.
We were totally wrong on our table but it was still a lot of fun!
