Три часа. Стратмор поднял брови. - Целых три часа. Так долго. Сьюзан нахмурилась, почувствовав себя слегка оскорбленной.
Казалось, все происходящее было от нее безумно. Джабба вздохнул и снова вытер пот со лба. По выражению его лица было ясно: то, что он собирается сказать, не понравится директору и остальным. - Этот червь, - начал он, - не обычный переродившийся цикл. Это избирательный цикл. Иными словами, это червь со своими пристрастиями.
Три. Она перевела взгляд на пустую шифровалку. Скорее бы просигналил ее терминал. Но тот молчал. Конец лета. Солнце уже зашло. Над головой автоматически зажглись лампы дневного света.
Мне нужен ключ, - повторила Сьюзан. - У меня его. Отпусти меня! - Он попробовал приподняться, но не смог даже повернуться. В перерывах между сигналами Сьюзан выкрикнула: - Ты - Северная Дакота, Энсей Танкадо передал тебе копию ключа. Он нужен мне немедленно.
Хорошо, хорошо. - Мидж вздохнула. - Я ошиблась. - Она сдвинула брови, задумавшись, почему ТРАНСТЕКСТ за весь день не взломал ни единого шифра.

Я серьезно. Рано или поздно я отсюда смоюсь. - Я этого не переживу. В этот момент Сьюзан поймала себя на том, что готова взвалить на Хейла вину за все свои неприятности. За Цифровую крепость, волнения из-за Дэвида, зато, что не поехала в Смоуки-Маунтинс, - хотя он был ко всему этому не причастен.
Нет, вообще-то я… - Из туристического бюро. - Нет, я… - Слушайте, я знаю, зачем вы пришли! - Старик попытался сесть в кровати. - Меня не удастся запугать.
Подумайте, - продолжал настаивать Беккер. - Очень важно, чтобы досье консульства было как можно более полным. Мне нужно подтвердить ваш рассказ заявлениями других свидетелей. Необходима любая информация, которая поможет мне их разыскать. Но Клушар не слушал.
