Description

By Dan Brown

The National Security Agency has a machine that can break any code, which means no private message anywhere is actually private. Then it meets one it cannot break.

Susan Fletcher, the agency’s head cryptographer, is called in on a Saturday, and discovers that the algorithm was written by a former employee who intends to make the machine’s existence public. Brown’s first novel, on government surveillance and what it costs.
