An interesting blend of elements, and evidently the fourth book starring Phil D’Amato. [Another review calls it book 2; it sounds like this is the first full novel following a collection of short stories.] It feels like a detective story much of the time; Phil is trying to find a serial killer and his bosses are on him to produce the killer. The other half of the book, however, is an interesting complication (memory loss, possibly drug or disease induced), which twines into the serial killer plot in interesting ways.
Phil travels a lot for his job– to Scotland, Los Angeles, and Chicago, which surprised me given that he’s an NYC detective. Along the way he interacts with a number of interesting people– thrown at him from both sides of the case. The memory subplot is clearly the heart of the story, with interesting characters and conundrums, and a lot of information passed to the reader about the structure of the brain, bacteria communication, and more.
The end is satisfying and properly links up the plots; while victory is secured, it’s not a white hatted hero who makes it all come together. The shifting alliances and trust are interesting throughout. I liked his girlfriend, but her depth seems to depend on earlier stories– while I liked her, she didn’t pop the way other characters did.
