Who Is Inspector Goole and what Is His Function in the Play?

John Boynton Priestley wrote the play, ? An Inspector Calls? in 1941 when the Second World War was being fought. The play involves a supernatural person, who claims to be an Inspector, arriving with the news of a suicide. A young girl has taken her life, due to a series of problems that occurred in her last year or so and everyone in the house at that time is somehow connected with her death, although the audience is unaware of that at first.
