did you check the resources page? i can tell you random facts and help you consolidate and analyse info, but asking for info on the general area of crime fiction is actually a harder question than they would ask in the hsc, as it is way more broad!
top of my head:
anils is post modern, a hybrid of political allegory and detective fiction (showing the eclectic nature of genre)
...
conventional metaphysical elements of crime fiction are missing (eg an acceptable resolution, ideas of justice) however the metaphor at the end of the novel ("a sweet touch from this world?") shows some degree of hope, giving an ambiguous nature to genre.
didnt do anils for hsc coz i thought it was shit, but yeah.
big sleep:
hard boiled decective novel / romance (links to other point re: genre)
marlowe as the maverick (link to anils character of woman, scientist as opposed to instictual, man - this shows how major elements of genre eg characterisation changes with context)
traditional elements are present eg justice and restoration/resolution however the macabre denouement offers a degree of ambiguity.
im kinda just rambling here but yeah anytthing specific just pm me or some1 else
