Query: duh is right

I dont have anything to do add except that I really enjoyed this book and Im a bit confused about the reviews that said that they figured out who the killer is before the detective did and that they could see it coming. MacKinty tells you who the killer is in the very first chapter. Read the free extract - the killer gets named at the bottom of page 6! Let me repeat MacKinty gives you the killer's name. You're supposed to know who the killer is, you're not figuring anything out. This isn't a mystery novel is a noir thriller. Duh indeed.
