By Clifford Stoll. How the Cold War's "Hanover Hacker," Karl Koch, was discovered selling U.S. secrets to the KGB, by the white hat who discovered Koch in the system. This is a first edition, so I assume it doesn't get into Koch's mysterious death at around publication time (it was ruled a suicide by self-immolation (!) but under the circs it can't be that simple).
This is a first, like I said, but a former library copy, with card sleeve in the front and various Kankakee Community College stamps on the page edges and inside. It's well-preserved, though, and a fantastic reading copy (the CompuServe account info in the intro alone! I had one of those...but enough about how I'm a fossil).
