A policeman interrupts a rich family's dinner to question them about the suicide of a young working-class girl. As their guilty secrets are gradually revealed over the course of the evening, 'An Inspector Calls', J. B. Priestley's most famous play, shows us the terrible consequences of poverty and inequality. The other powerful plays in this collection - 'Time and the Conways', 'I Have Been Here Before' and 'The Linden Tree' - explore time, fate, free will and the effects of war.
