Just finished this book, which arrived only yesterday. It was a very good read and I wish I had another one to read straight away. What I liked about it was the tension and the terror. It is a scary book - both the cop and the killer are a little hard to take sometimes, but the cop has many qualities which redeem him. It's got plenty of meat to it, not like a late Patterson, much more substance to the story which is intricate, terrifying and tense.
It is the story of a pretty focused NYPD detective who doesn't care much for the obstacles in his way or for bad cops around him, but who works and leads his team with some strength and has a lot of loyalty in the department. He is an interesting mix, as is the book - lots of painstaking police work, which I found fascinating, a sifting of facts and deductions, mixed with the thrills of psychological profiling and chases and confrontations. It has many a heart-stopping moment and can, at times, be so intense or vivid that you pull back. But you just want more of the story and it does turn the pages, over and over and over. He works alongside a well-drawn female lead who is taking her first steps into criminal profiling. The balance is great, the relationship fizzes throughout.
The length of the book is something I enjoyed - it's not a single idea played out, but five or six ideas intermingled and that gives a lot of different journeys to follow and lots of dead ends and frustrated leads. There is time to get to know the case and the characters, but it still pulls you on and towards the end, the flow is very fast. I suppose that, at times, the procedural aspects slow the thriller aspect, but I thought this worked - but it makes the start slower than the end as all the pieces are set up and explored.
As a piece of genre-fiction, it contains many elements seen before - the hard-bitten cop, the terrifying killer, the frightening battle between evil and good, puzzles and deduction, good cops and bad cops. But this tried and tested formula works for a reason, it contains all the thrills you want from a thriller. I didn't think it was derivative, although it has many similar elements to other books. I thought it was remarkably fresh and unusually well-written, with interesting ideas and insights.
The killer is complex and because you see him in action, he is horrible. Although, I have to say that most, if not all, of the violence is off-camera, and it handles this difficult balance well.
I think it's a four star book, but as a debut, worth five, because it shows ambition and is grappling with so much and keeping everything balanced, up in the air and exciting.
In conclusion, it really thrilled and scared me, gave me a good intellectual journey of trying to work things out for myself, and also gave me characters I liked and got to feel some affinity for. So, well done, a great new thriller.
