A representative, supposedly, of the local police force, sent to investigate Eva Smith/Daisy Renton’s suicide. The Inspector asks all the Birlings, and Gerald, questions about Eva/Daisy. It seems that the Inspector knows the answer to everything he asks, but wants the family to admit to various instances of wrongdoing. At the close of the play, the characters wonder aloud whether the Inspector is actually a policeman, and the constabulary confirms that no such man serves on the force. But this does not explain why the Inspector, who seems to have socialist sympathies, would have come to the house, or how he could have known so much about Eva/Daisy and the Birlings.
