I can't deny that I still need to read a lot to get to know Stephen King's work in novels. Basically my contact with his work has been on the adaptations of his works on films, mini-series, and on, that in that regard it has been quite a lot since I have watched almost all the major adaptations made.
However, I thought that this book can be a priceless option since not only didn't require having read any other book before, but also, himself had described as his first "hard-boiled" detective novel, so, it meant that this supposed to be away from his traditional horror books (knowing well that he has written other kind of stories besides horror genre's pieces).
Something that I truly like was that he did some references to other of his novels but using the film adaptations of them, in that way, it was clear to me that this story was in a different "universe" than the one of the previous horror novels that it's usual to have some "cross-over" references implying that the characters "exist" in the same shared book universe.
...a single moment of forgetfulness had led to horrific consequences.
It was an odd experience, since while I need to read more material from Stephen King, I have read a lot by Dean Koontz, and I found several similarities on this story. I know that daring to comment something like that must be like compare a Star Trek novel with one of Star Wars, however I did found some elements traditional to get in Koontz's books: A smart dog, a peculiar female character on a prominent support role, a car chase (kinda), a psychotic killer, and there is must be something else, but so far, those are which came to mind now. Also, while this is supposed to be "first" by King on this genre, well, honestly, Koontz has written several novels on this narrative style, with a protagonist dealing with some wacko psycho killer who wants the protagonist to die, just that those were refering as horror novels, without a so clear "distinction" to be considered "hard-boiled" detective novel.
That that gets me to another point. Honestly, I didn't felt it as a "hard-boiled" detective novel, or even a detective novel in a general sense. True, the protagonist is a detective, a retired police detective to be specific, but having a detective as protagonist doesn't make a book a detective novel in my opinion. Due that since the beginning you know who the antagonist is, you know who did the crime, and at least for me, the main fun in a detective novel is the struggling to find the culprit. But here, is basically a manhunt. True, he needed to use some deduction skills to find the identity of the killer (that it's kinda boring since one (the reader) knows it from the beginning) even to contact people to help him in doing that, that even that at some moments was maddening since some explanations of why the killer did his tricks were too obvious so waiting a lot of pages to certify something that you already know how was done was shocking (in the bad sense.
...almost never won a kewpie doll at the county fair.
Another thing that I found odd is that well, I notice too much similarities on the antagonist with Norman Bates from Psycho, at least the film's Norman Bates (since I still need to read the novel to compare) but definitely the antagonist is nothing so fresh and/or original and well, it's Stephen King that we are talking about and I'd expect a more original character.
I had struggles with the protagonist, not at first, he was doing quite well, but without spoiling, there is a crutial moment, when he is affected by an attack made by the antagonist where the result should be too shocking, but I didn't felt it in that way, he was able to think, he was able to start to give orders to his "sidekicks" in a very reasonable way, and honestly, I thought that he'd need at least a day, if not more to cope with what happened and then, to start to think in a counter-strategy. The story keeps telling to the reader that he is supposed to be sad, but honestly I felt it as cold as the antagonist.
...most people are sheep and sheep don't eat meat.
On the climax (don't worry I won't do spoilers) the protagonist isn't the "hero", I mean the one to catch with his own hands the evil antagonist and it's something done by the "sidekicks", and I think that there is a reason of why a character is the protagonist and why others are supportive characters and/or "sidekicks".
And I think that the book had too much pages in a story like this one, investing pages in detailing sub-events that they aren't so relevant or that they could be narrated faster without so many details. Fewer pages and a faster tempo could increase the possitive impact of the overall story.
