Even though I was able to guess the true culprit behind the murder when I was about half way through the book, I still found it very suspenseful. In fact, it only took me a few days to read it because I couldn't put it down. Yes, the main character turns out to be a total jerk, and there ae some loose ends that are left dangling, but I found the plot line realistic in the sense that the cops don't always get their guy, and criminals can slither through cracks in the justice system if they know how. Best friends don't always stay that way forever, no matter how close they seem at the time. I could have done without some of the unprofessional banter, but I'm not a cop and have never been questioned by them, so maybe they really do act that way. If Tanna French puts out another Dublin Murder Squad book, I would read it. Hopefully, the protagonist would be a little more considerate of others.
