A decent little thriller if you enjoy cop shows with serial killers. It's an enjoyable read if you want a thriller that won't have you trying to figure everything out but takes you along for the ride.
Some notes with slight spoilers:
This book is heavy on the talk of body weight and what people are eating (very important part of the motive).
The way men and women deal with each other feels a bit sexist, imo and very heavily shows the time this book was written (2003)
And lastly, they touch on being transsexual and while it's dealt with in a mostly ok way, it does have some comments from a character that are derogatory.
