A sentimental favorite, The Cuckoo's Egg seems to have inspired a whole category of books exploring the quest to capture computer criminals. Still, even several years after its initial publication and after much imitation, the book remains a good read with an engaging story line and a critical outlook, as Clifford Stoll becomes, almost unwillingly, a one-man security force trying to track down faceless criminals who've invaded the university computer lab he stewards. What first appears as a 75-cent accounting error in a computer log is eventually revealed to be a ring of industrial espionage, primarily thanks to Stoll's persistence and intellectual tenacity.
