Delete All Suspects

After a hit-and-run leaves young techie Eddie Stallman in the hospital, Turing Hopper, a sentient computer, helps her PI friend Tim find out who did it. Their investigation uncovers evidence of spamming, phishing, and other unsavory online crimes. But when the feds show up looking for an online vigilante who's also using Eddie's computers, Turing and friends are caught in the middle. They can't let the vigilante continue--but they can't tell the FBI everything without revealing Turing's identity to the world.
