Gregg Hurwitz knows how to write a good suspense story and the action does keep moving in this book. What makes this book less enjoyable is that there seemed to be a (what I thought of) "baton of gross incompetence" that was passed between the police and protagonist. It seemed to me that throughout the story, someone or some group was constantly making an unbelievably and uncharacteristically stupid decision. I get that one always needs to suspend a certain level of disbelief when reading good thrillers, but this book really took it up a notch. Think of it as the opposite of a deus ex machina that sweeps in to "save the day" with an unbelievable thing (e.g., in the new Magnum PI, the Juliet Higgins character seems to be able to access real-time satellite images at moments notice along with facial recognition software such that whenever they lose a suspect, they call Higgins and she finds the person within 5 minutes). Well, in this book, its the opposite - things seem settled, before someone makes an unbelievably stupid move and the suspect gets away again. The protagonist, Dr. David Spier is likeable enough, but his utter incompetence and idiocy is incredibly costly. Aside from that, I found that some threads were raised to give color to the story at one point, then completely dropped and never followed up on subsequently. This was one of Hurwitz's earliest books, and while one can see the story telling skill strongly, it is clear that Hurwitz still needed to work out some plotting issues. This is a good book for Hurwitz fans to read. If you haven't read Hurwitz yet, my suggestion is to start with one of his later books.
