After changing his appearance, Peter Brown appeared in Middle City, a provincial capital with a large flow of people. In such an environment, and dressed in ordinary clothes, Peter Brown's identity would not attract attention.
This time, Peter had created a new identity for himself using computer technology as an orphan from an orphanage that had already closed down. The person he had adopted the identity from was already deceased.
Now, Peter's name was Barrett Walter, a name as ordinary as it could be.
Peter Brown did not rely on Robert Williams and others to establish his own identity. Instead, he used computer technology to infiltrate the network and created an identity for himself, which he had done playfully while learning hacker skills during his free time. Now, it served to hide his true identity well.
