Mystery at the Burlesque (1949)

The theatre in which the action takes place is London's Soho-district Windmill Theatre, that claims to have never missed a performance during the Nazi blitz, with the members of The Windmill Theatre Troupe taking part and putting on their regular performance as the fictional story takes place. The story opens with the finding of a dead body in the front row of the theatre after the audience has departed. The police are summoned, and they send the troupe through their numbers as a means of determining which of the players or stage employees were in the position to fire the shot which killed the victim at the time and from the angle it is known to have been fired. The show, for the film, has five production numbers.
