Using her knowledge of the backdoor and a password found in Devlin's wallet, Bennett logs into the Bethesda Naval Hospital's computers and learns that Under Secretary of Defense Bergstrom, who had opposed Gatekeeper's use by the federal government, was murdered by altering the medical results leading to a misdiagnosis. Fellow hacker "Cyberbob" connects π with the "Praetorians," a notorious group of cyberterrorists linked to recent computer failures around the country. Bennett and Cyberbob plan to meet, but the Praetorians intercept their online chat. Bennett escapes from Devlin—a contract killer for the cyberterrorists, but the Praetorians kill Champion by tampering with pharmacy and hospital computer records. After Bennett is arrested by the California Highway Patrol, a man identifying himself as Champion's FBI friend frees her from jail. She realises he is an impostor and escapes again.
