The Angel of Knowlton Park by Kate Clark Flora

This is the first in a mystery series starring Joe Burgess, a cop in Portland, Maine. I lived in Portland for eight years and thought it would be fun to read a book taking place there. This is a gritty mystery involving the death of a child, drug dealers and pedophiles. It's not for everyone. I liked it enough that I'll read the next in the series. I have a feeling that the books will get better as Flora gets comfortable with Joe.
