"Crime texts are usually set in a contemporary urban environment"

"Iconography as a term was derived in Erwin Panofsky's (1955) art criticism and referred only to the visual signs"

"We also associate aural signs with particular genres"

"We associate guns and decrepit city streets with the crime genre"

"Iconographic sounds refer both to diegetic and non-diegetic sounds. In crime texts, the sound of a police car's siren (diegetic) is usually endemic"

"Maybe all genre texts follow the conventional narrative structure described by Todorov and Propp, they tell their stories in different ways" 

"The typical crime story involves the hero solving the crime in order to catch the villain"

"The detective story formula centres upon the detective's investigation and solution of the crime"

"The six main phases of this pattern: (a) introduction of the detective; (b) crime and clues; (c) investigation; (d) announcement of the solution; (e) explanation of the solution; (f) denouement" - cited by Edgar Allan Poe

"The usual relationship in a Film Noir is that the male character (private eye, cop, journalist, government agent, war veteran, criminal, lowlife) has a choice between two women: the beautiful and the dutiful. The dutiful woman is pretty, reliable and always there for him, in love with him, responsible - all the things any real man would dream about. The beautiful woman is the femme fatale, who is gorgeous, unreliable, never there for him, in love with him, irresponsible - all the things a man needs to get him excited about a woman. The Film Noir follows our hero as he makes his choice, or his choice is made for him. "
