The play "An Inspector Calls" opens with Mr. and Mrs. Birling, Sheila Birling, Eric Birling, and Gerald Croft celebrating Sheila's engagement to Gerald
Mr. Birling is happy about the engagement as it could benefit his business by building links with Crofts Limited, owned by Gerald's parents
The engagement is treated more like a business transaction rather than a celebration of love between the couple
Mr. Birling mentions the Titanic as unsinkable and expresses his views on war, which the audience knows to be mistaken given the historical events that followed
Inspector Ghoul arrives to investigate the death of a young lady, Eva Smith, who committed suicide by drinking disinfectant
Mr. Birling admits to sacking Eva from his factory due to her involvement in strike action over wages, showing his lack of concern for those affected by his actions
Sheila is deeply affected upon learning about Eva's death and her own role in it, unlike her father who shows little remorse
Eva changed her name to Daisy Renton after being sacked from Mill Woods department store where Sheila got her fired due to a misunderstanding about a dress
Gerald reveals he had a relationship with Eva/Daisy, showing his involvement in Eva's life and adding to the mystery of the story
The act ends with Gerald believing he can keep his affair with Daisy a secret, but Sheila knows that the Inspector is aware of the truth
The word "well" repeated by the Inspector at the end of the act adds emphasis to the mystery surrounding Eva's life and death
