I'm somewhat ambivalent about this book. I really wanted to like it but for reasons detailed below I can only "rather" like it instead of "really" liking it.
As a thriller / procedural, it rates a healthy 3.5 stars plus. The storyline is good, it maintains a good pace and builds suspense, and it keeps you guessing until a fairly late stage, even though I had already figured SOME of it out by then. The killer is ominous and dangerous, the internal politics add another dimension to the investigator's struggles, and overall it is a well constructed plot.
Where it failed for me was the characters. The main heroine is selfish and self-pitying, and surprisingly naive for a Detective Inspector. Her partner, an overweight DS, seems to lack any investigative, interrogative or interpersonal skills, yet is billed as a "good copper". And then there is Jacques, the Medical Examiner who wins Lorne over from despising him to being infatuated by him simply by standing close to her and smiling at a crime scene (I wish someone had told me that was all it took when I was young and single.....). He then becomes so nosey and invasive as to be downright creepy, yet Lorne sees no problem with this. Add in a whinging husband, a new boss who seems to have risen to a high position despite being both petty and incompetent, and you get the general idea. At best, 2 stars for the cast.
Overall a three star rating that could have been a good 4 had there been just one character I could find plausible or even vaguely likeable. Lorne didn't even come into the tale battle scarred or damaged by a bad history like Harrys Hole or Bosch, she simply thinks the world is against her for no reason, and because of that she instils no sympathy or, sadly, loyalty to follow her into the next book.
I will try something else from M.A. Comley for sure, but I doubt it will be the rest of the Justice series; sadly, I have more appealing prospects on my long to-read list.
