Бринкерхофф отвернулся. - Чед, уверяю тебя, в шифровалке творится что-то непонятное. Не знаю, почему Фонтейн прикидывается идиотом, но ТРАНСТЕКСТ в опасности. Там происходит что-то очень серьезное.

Отключение - сложный процесс. Это была правда. Банк данных АНБ был сконструирован таким образом, чтобы никогда не оставался без электропитания - в результате случайности или злого умысла.
