I did the pussy approach by fence sitting in my response.
I said that the different sub genres of crime fiction have different purposes, and for some sub-genres, this was to expose an entertaining situation and provide closure with the discovery of a criminal, etc. so in that respect i agreed with the question.
But then I went to on to talk about how the changing context and the needs of the repsonders as their world became more transgressive and dark mant that sub-genres like the Hard Boiled one exposed more than mystery and discovery; it exposed social structures and injustices, etc.
I thought the question was difficult, because you had to be imaginative in order to broaden it's depth.
(I thought that was a very good thing though).
Sixteen pages. Hand cramps. Gah!
