I recently had nothing better to do than to read Håkan Nesser's The Darkest Day. I did finish it, and it was alright I guess, but I was pretty disappointed.
I actually liked the family drama which takes like 200 pages before the detective even enters the picture, which some people online seemed to complain about, but the characters and their relationships were interesting enough that I was pretty hooked at that point. The whole detective story aspect of it made it fall flatter than expected when it kicked in though, since there was like... nothing of substance to the mystery whatsoever. I guess it wasn't even supposed to be the point of the book since the solution was not only super simple and obvious from the get-go, but also explicitly revealed to the audience like halfway through the book, way before the detective figured it out, but for something that wasn't supposed to be the point, it took the spotlight a ton. The family drama did continue on the side as the investigation progressed (or mostly, didn't progress), and that continued to be interesting, but honestly I would have rather just read the exact same story told completely from the family members' perspectives without even an attempt to include a mystery at all.
