OK I just finished Deception Point, I am reading Dan Brown in order as I like to do. It really let's you see the author evolve. I really like DP, maybe more so than DF since it has some geology in it probably. Anyways, there were some technical gliches but the story was very good. GPR - Ground Penetrating Radar does not have the resolution to see a coat, body yes, coat no, and it takes more than a one second shot to resolve an image. They would have had to shoot several tens of shots to resolve the extraction pit. Anyone else read this, it seems to be overlooked by most that read Brown.
