The play can be seen as a morality play or a work of detective fiction
Morality play:
An allegorical drama popular in Europe during the 15th and 16th centuries
Characters personify moral qualities like charity or vice
Teaches moral lessons about good and evil
Characters in "An Inspector Calls" typify certain character traits like the seven deadly sins
Inspector Gall investigates the suicide of Eva Smith, inverting the traditional detective story by finding nearly all characters guilty
Sentence structure in Inspector Gall's speech uses anadiplosis to show joint responsibility for Eva's death
Setting in "An Inspector Calls"
All three acts take place in the dining room of the Burling's house
The continuous setting suggests self-absorption and disconnectedness from the wider world
Creates a claustrophobic mood and focuses on the moral lesson of the play
The lack of scene changes allows for a precise focus on the moral message of the play
Inspector Gall's vagueness as a character adds to the focus on the moral message
Inspector Gould is portrayed as a character who reveals more about what he doesn't do rather than what he does do
Inspector Gould is depicted as a moral force who pursues the wrongs committed by the Burlings and demands they face the consequences of their actions
Inspector Gould is presented as less of a person and more as a moral lesson, emphasizing the message that "we are members of one body, responsible for each other"
The overarching message that J.B. Priestley wants the audience to take from "An Inspector Calls" is an attack on capitalist values
Dramatic irony is used in the play to highlight the contrast between characters' knowledge and the audience's knowledge
Mr. Birling's statement about the Titanic being "unsinkable, absolutely unsinkable" is a clear example of dramatic irony, emphasizing his ignorance and flawed beliefs
The repetition of the word "unsinkable" and the intensifier "absolutely" deepen the dramatic irony and highlight the extent of Mr. Birling's error
Edna, despite being a minor character, is significant in the play's exploration of class dynamics
Mr. Birling's harsh and condescending communication towards Edna reflects the class divide and power dynamics within the play
The imperatives and short, monosyllabic sentences used by Mr. Birling towards Edna show his lack of politeness and respect towards her
Edna's portrayal as a working-class woman who is expected to obey her middle-class employer without question adds to the pressure faced by working-class individuals
