Susan Fletcher is the head cryptographer at the NSA and has a romantic weekend planned with her fiance. He gets called away on an emergency and it's not long before Susan also receives a call from her boss. She needs to come in to work and not say anything.
Once she's in to work she's debriefed by her boss. The super computer that the NSA has built and has never spent more than 3 hours cracking a code has been chugging away for more than 12 hours now. It has finally found the unbreakable code. This will be a complete reset for the NSA and their super expensive machine will become useless. The NSA can't let this happen.
Even though it's the weekend, there are others hanging around the NSA and they cannot find out. But the NSA is full of suspicious people and it's only a matter of time.
The setting for this book is interesting, taking place completely at the NSA headquarters. Despite this book being pretty old by now, it still reads as if it could happen in current day. The story starts off interesting. This code is unbreakable, what is the NSA missing and how do they find the code. It devolves into something completely unbelievable and overblown. The ending was pretty weak and at that point I was just happy the story was coming to a close. This probably my least favourite Dan Brown book.
First Line: "It said that in death, all things become clear; Ensei Tankado now knew it was true."
