I love the Amos Decker character and his relationship with his FBI partner Alex, and his best friend Melvin Mars. He is a very complex man, with a photographic memory, which happened when he was hit in his head while playing major league football.
This is the third book, where Amos, Alex and his FBI crew are looking into a murder of a young woman, committed in front of the FBI building and witnessed by Amos. The man then turned the gun on himself.
The story goes on with lots of twists and turns, as the FBI could not find any connection between the shooter and the victim. I was so glad to see Melvin playing a big part as he meets Harper Brown, a DIA Agent,and they are instantly attracted to each other. She tells them to back off the investigation since it's a high priority spy case. They make a pact to help each other.
The ending was eventful, exciting and tense and I was surprised at the outcome.
