Non-fiction. A new worker at a huge central computer at a Berkeley lab was given the job of finding out why user accounts were out by 75 cents. He ended up in a hunt for a hacker who was using the Californian computer to infiltrate dozens of other systems with an aim that was very dangerous to U.S. security. This is a gripping thriller, all the better because it is true.
