Amid the uproar of a medieval cafe, its staff are staging a Mystery Play – loves and fishes are multiplying. Mystery Steps runs until Saturday in Shelton Square, central Coventry, as part of Coventry Mysteries. The piece contains lots of miniature theatre puzzles to work out, games to play, visual jokes, hidden things, things to make kids go ‘eeeergh’, a whole tongue-in-cheek world to explore.
