His new worm, which he calls a "phage", cannot be removed without dismantling the entire network. Possibly encouraged by the government, local gangs and tribes raid Precipice, burning down Nick and Kate's house before being overwhelmed by the dogs. Nick, suffering another overload, blames Kate for the incident, since she, following Hearing Aid policy, cut off a call from someone attempting to warn Precipice. He hits her, and then, filled with remorse, leaves the town. He finally reveals his location to the authorities when, encountering one of the "Roman circus" operations which broadcast live fights and other bloody exhibitions to the country, he responds to an "all comers" challenge by the father of the leader of one of the gangs, and cripples him in front of a nationwide audience. At Tarnover, Paul Freeman takes charge of the interrogation. He was the representative whom Nick, as Sandy Locke, was supposed to meet at G2S. Freeman, a tall gaunt African-American, gradually comes to realise that he has more sympathy with Nick's views than his employer's, and eventually absconds himself, giving Nick computer access so that Nick can make his own escape. The precipitating event in this case is Kate's abduction by government agents, who bring her to Tarnover for further questioning and to threaten Nick. With the code he gets from Freeman, he sets up an identity as an Army major, with Kate as his prisoner. Once clear of Tarnover, they disappear together. This time around, Nick has another plan, and rather than running and hiding, he and Kate spend a number of months travelling the country, aided by an "invisible college" of academics who are allies or former residents of Precipice. He creates a new "worm" which is designed to destroy all secrecy. (Brunner invented the term "worm" for this program, as a self-replicating program that propagates across a computer network – the word was later adopted by computer researchers as the name for this type of program.) The worm is eventually activated, and the details of all the government's dark secrets (clandestine genetic experimentation that produces crippled children, bribes and kickbacks from corporations, concealed crimes of high public officials) now become accessible from anywhere on the network – in fact, those most affected by a particular crime of a government official are emailed the full details. In place of the old system, Nick has designed the worm to enforce a kind of utilitarian socialism, with people's worth being defined by their roles in society, not their connections in high places.
