Like all other Dan Brown novels this one also starts with a murder. The murdered person, Ensei Tankado was an employee of the National Security Agency, who wrote an unbreakable code which the NSA’s powerful codebreaking machine could not crack. Enter Susan Fletcher, a brilliant and beautiful cryptographer.
At the same time the deputy director of NSA has sent Susan’s boyfriend to retrieve a ring from the dead body in Spain where he is followed by a mysterious assasin. As Susan Fletcher discovers more secrets, you start turning pages more rapidly and as the cover of the book says
The NSA is being held hostage… not by guns or bombs, but by a code so ingeniously complex that if released it will cripple U.S. intelligence. Caught in an accelerating tempest of secrecy and lies, Susan Fletcher battles to save the agency she believes in. Betrayed on all sides she finds herself fighting not only for her country, but for her life, and in the end, for the life of the man she loves.
This book has too much excitement. Each chapter is like one page and ends in a cliff hanger. When you have three hundred such pages, it gets a bit boring and cliched. But you read page one and you cannot keep the book down.
