The Human stain First Thoughts

My first thoughts that came to me were, who is the narrator? There is not much information on this guy, and its hard to tell who the narrator is until he starts talking to Coleman. I liked how the book opened up about what was going on during this time period like the Clinton affair. This shows how Coleman and Clinton are extremely similar. I am confused on how the wife died, and weather his affair had anything to do with her death.
