The characters we see as the curtain rises are not the same as those at the plays conclusion. The events of the evening change everyone, as well as their expectations of the future. Inspector Goole is instrumental in disturbing the harmony; a purposeful, mysterious character who forces the characters to confront each other's social responsibility, snobbery and guilt. But is the inspector as genuine as he seems?
All these changes take place because of the visit of Inspector Goole. But who is Inspector Goole? And who is the girl whose suicide he is apparently investigating?
