Delete All Suspects (A Turing Hopper Mystery)

After a hit-and-run leaves a young techie named Eddie in the hospital, Turing, an almost-sentient computer, tries to help her PI friend Tim find out who did it. While Turing tries to break into Eddie's computers, her human friends do the legwork. It seems Eddie lets his seedy friends use his computers-and some are running highly unsavory websites. Others are using spam to con people out of their credit card numbers. Then the feds show up, looking for an online vigilante who's also using Eddie's computers. Now Turing and her friends are caught in the middle. They can't let the vigilante continue-but they also can't tell the FBI everything without revealing Turing's identity to the world.
