From the introduction: In Joker’s Wild, the players are in town between adventures and enjoying a night out, find themselves forced to do the bidding of an evil master criminal. As time ticks away, they must find and steal a magnificent gem and figure out the question on the lips of the town watch - who is Lister Vergo? As with other Critical Hits, text inside a border should be read aloud to the players (unless you have modified the setting, in which case you’re on your own!).
