Some clues about story in crime fiction

I want to begin my talk at this colloquium by saying from the start that I am outclassed here. I have published one crime novel, and while I have used some aspects of the crime genre in my current novel - notably a kind of mystery and a movement towards resolution - I would not classify myself as an expert. What I do know about is the teaching of writing, the value of plot and the ever-important idea of story. Story and aspects of plot are vital ingredients in crime fiction and so I come to the task of writing this paper searching for more clues about how to write story in crime fiction.
