Kind of a hybrid between an escape room and a scavenger hunt. The basic concept is that someone's been killed playing a mysterious game and the only way to find the killer is by playing the game too. Basically, the killers clues take you on a nice route through town and you have to work out their identity from what they say, their tastes, how they talk, etc. Good fun and great value. It took us over two hours to complete and there was a really nice range of clues. Couple of decent pub stops too. Would recommend. Great way to explore the city.
