The Birlings were celebrating Gerald and Shelia's engagement by having a big dinner, but whilst they are celebrating someone knocks at the door.
The inspector tells the Mr Birling that one of his workers, Eva Smith had committed suicide. The inspector then investigates further.
Mr Birling reveals that he fired Eva for going on strike, but doesn't take any responsibility for her death.
The whole family confess to having a part in Evas death. Gerald had an affair with Eva, Mrs Birling didnt help Eva and Eric was the father of Evas unborn Baby.
The inspector leaves and then Mr Birling calls the infirmary to see if Eva had died. The infirmary said no one had died from drinking disinfectant. They all start to think that the inspector is an imposter.
The police call Mr Birling and tell him that a girl has died from drinking disinfectant.
