"An Inspector Calls" is a play by J.B. Priestley that uses the story of a wealthy family’s encounter with a mysterious inspector to critique class divisions, social responsibility, and the hypocrisy of pre-World War I society. The family’s complacency and selfishness are challenged as the inspector reveals their collective role in the suicide of a young working-class woman. The play concludes on a cliffhanger, leaving the audience to ponder whether the family will learn from their mistakes and embrace a more compassionate approach to society.
