Сьюзан отнеслась к словам Стратмора скептически. Ее удивило, что он так легко клюнул на эту приманку. - Коммандер, - возразила она, - Танкадо отлично понимал, что АНБ может найти его переписку в Интернете, он никогда не стал бы доверять секреты электронной почте. Это ловушка. Энсей Танкадо всучил вам Северную Дакоту, так как он знал, что вы начнете искать. Что бы ни содержалось в его посланиях, он хотел, чтобы вы их нашли, - это ложный след. - У тебя хорошее чутье, - парировал Стратмор, - но есть кое-что .

Черный лед. В центре помещения из пола торчала, подобно носу исполинской торпеды, верхняя часть машины, ради которой было возведено все здание. Ее черный лоснящийся верх поднимался на двадцать три фута, а сама она уходила далеко вниз, под пол.

 Ладно, - процедил Стратмор.  - Итак, даже в самых экстремальных условиях самый длинный шифр продержался в ТРАНСТЕКСТЕ около трех часов.
