<P> Goole's questioning revealed that each member of the family had contributed to Eva's despondency and suicide . He reminds the Birlings that actions have consequences, and that all people are intertwined in one society, saying, "If men will not learn that lesson, then they will be taught it in fire and blood and anguish", alluding to the impending World War . Goole then leaves . </P> <P> Gerald returns, telling the family that there may be no "Inspector Goole" on the police force . Arthur makes a call to the Chief Constable, who confirms this . Gerald points out that as Goole was lying about being a policeman, there may be no dead girl . Placing a second call to the local infirmary, Gerald determines that no recent cases of suicide have been reported . The elder Birlings and Gerald celebrate, with Arthur dismissing the evening's events as "moonshine" and "bluffing". The younger Birlings, however, still realise the error of their ways and promise to change . Gerald is keen to resume his engagement to Sheila, but she is reluctant, since he still admitted to having had an affair . </P> <P> The play ends with a telephone call, taken by Arthur, who reports that a young woman has died, a suspected case of suicide by disinfectant, and that the local police are on their way to question the Birlings . The true identity of Goole is never explained, but it is clear that the family's confessions over the course of the evening are true, and that they will be disgraced publicly when news of their involvement in Eva's demise is revealed . </P> <P> A mysterious interrogator who introduces himself as "Inspector Goole", claiming that he has seen the dead body of Eva Smith / Daisy Renton earlier that day after her slow and painful suicide by swallowing disinfectant, and that he has been given "a duty" to investigate the Birlings' responsibility for her death . He makes a brief reference to a diary left by Eva / Daisy although this is never seen or explicitly referred to . Throughout the play, it is suggested that Goole knows everything about Eva / Daisy's life and the Birlings' involvement in her death, and is interrogating the family solely to reveal their guilt rather than to discover unknown information . Both during and after his interrogation of the family, the Birlings query whether he is actually a real inspector, and a phone call made by Mr. Birling to the local police station reveals that there is no Inspector Goole in the local police force . Many critics and audiences have interpreted Goole's role as an "avenging angel" or a supernatural being because of his unexplained omniscience, his prophetic final speech in which he says that humanity will learn its lesson in "fire and blood and anguish" (referring to the First World War, two years after the setting of the play 1912) and even because of his name, which is a homophone for the word "ghoul" (meaning "ghost") and is also the name of a seaside town (which could possibly be a reference to the time period in the play when Eva Smith stays in a seaside town with money that Gerald Croft had given her). It is suggested in the final scene that Goole's interrogation of the family will foreshadow a further interrogation to follow by the "real" police force, and that Goole's purpose has been to warn the family in advance and encourage them to accept responsibility and repent for their bad behaviour, like The Ghost of Christmas Yet to Come . Goole also forces the characters to question their very own lives, and if the ones they were living were true . In addition, he also feels a responsibility to make the Birling family feel guilty for their actions . His identity remains ambiguous throughout the play . </P>
