Back when I was in school, I remember one of my English teachers telling us about a book she was about to read written from the perspective of both the killer and the killer's victim.
Each chapter flipped between the 2, and I think the victim was female and homeless, but this may be wrong. It was probably released around 1998-2000, although I'm not sure if it was newly released or an old book that she'd discovered.
I know it's a bit vague, but I've recently got back into reading a lot more, and remembered this story, thinking it could be interesting. I've Googled it, but found nothing, and was wondering if anyone here could help.
