"An Inspector Calls" is a play by J.B. Priestley, first performed in 1945. The play is set in 1912 in the home of the wealthy Birling family, and revolves around the unexpected arrival of an inspector investigating the suicide of a young woman. As the inspector interrogates each member of the family, it becomes clear that they all played a role in the woman's death, either through their actions or their indifference. Through the course of the play, Priestley critiques the selfishness and hypocrisy of the upper classes, and advocates for a more responsible and caring society. "An Inspector Calls" is considered a classic of 20th century British literature and has been adapted into multiple films and stage productions. It remains a powerful commentary on social inequality, responsibility, and morality.
