The Inspector is a character in J.B. Priestley’s play “An Inspector Calls,” and he serves to illustrate the idea that society can be improved if people accept responsibility for their actions and demonstrate empathy for others. The Inspector is a mysterious character who tests the morals and values of each character. He unexpectedly interrupts what seems to be a peaceful evening at the Birling home. By exposing their wrongdoing and compelling them to face their own accountability, he acts as a catalyst for change.

The Inspector, who stands in for Priestley’s socialist message, is a crucial figure in the play. His mannerisms and speech are chosen with the intention of unnerving the Birling family because he is presented as a figure of authority and power. The Inspector enters the home and immediately upsets the peace by interrogating each member of the family about their morality. He relentlessly questions the Birling family and will not be persuaded by their attempts to deflect responsibility.
