This is one of Kellerman's Alex Delaware books. While it's a good book, it's a little far fetched.
Alex and Milo are somehow manage to randomly pick scenarios out of thin air and make the crime fit the theory rather than the other way around. And they manage to solve the crime without having any evidence, and just their own thoughts.
Regardless, it's still and enjoying read and the main storyline is broken up in parts by Alex's love life, and the possible return of Robin, but these splits from the story don't spoil from the twists and turns of the main section. Although I did find Alison rather annoying with her pious attitude toward Alex and his police work.
Like I said there are a few twists and turns, but for the most part the ending is pretty obvious from about half way through, so the interesting thing is how Alex and Milo get from their theories to the conclusion without evidence.
One thing I found unusual about this book is that the victim is not a nice guy, but you actually end up having a little bit of sympathy for him, despite your best efforts not to.
