Привратник проводил его в фойе. - Багаж, сеньор. Я могу вам помочь. - Спасибо, не. Мне нужен консьерж.
Стратмор нахмурился: - Танкадо намерен назвать победителя аукциона завтра в полдень. Сьюзан почувствовала, что у нее сводит желудок. - А что. - Он говорит, что вручит победителю ключ. - Ключ. - В этом и заключается его замысел. Алгоритм есть уже у .
Эта светящаяся клавиатура управляла его личным лифтом. Стратмор и его высокопоставленные посетители попадали в шифровалку и уходили незаметно для остальных сотрудников. Лифт спускался на пятьдесят ярдов вниз и затем двигался вбок по укрепленному туннелю еще сто девять ярдов в подземное помещение основного комплекса агентства. Лифт, соединяющий шифровалку с основным зданием, получал питание из главного комплекса, и оно действовало, несмотря на отключение питания шифровалки. Стратмору, разумеется, это было хорошо известно, но даже когда Сьюзан порывалась уйти через главный выход, он не обмолвился об этом ни единым словом. Он не мог пока ее отпустить - время еще не пришло. И размышлял о том, что должен ей сказать, чтобы убедить остаться.
Если Танкадо убьют, этот человек опубликует пароль. - Его партнер опубликует ключ? - недоуменно переспросила Сьюзан. Стратмор кивнул: - Он разместит его в Интернете, напечатает в газетах, на рекламных щитах. Короче, он отдаст ключ публике. Глаза Сьюзан расширились. - Предоставит для бесплатного скачивания.
Звонок был сделан из страны с кодом один - из Соединенных Штатов. Нуматака удовлетворенно мотнул головой.
Далее в заметке сообщалось, что, хотя алгоритм вызвал громадный интерес в Японии, несколько американских производителей программного обеспечения, прослышавших о Цифровой крепости, считают эту информацию нелепой - чем-то вроде обещания превратить свинец в золото. Формула, утверждают они, - это мистификация, к которой не следует относиться серьезно. - Аукцион? - Сьюзан подняла .
Электронная почта от Энсея Танкадо, адресованная Грегу Хейлу. Они работали. Сьюзан буквально онемела, когда эта страшная правда дошла до ее сознания. Северная Дакота - это Грег Хейл. Глаза ее не отрывались от экрана.
Двухцветный посмотрел на часы Беккера. Его лицо казалось растерянным. - Обычно я напиваюсь только к четырем! - Он опять засмеялся.
Сьюзан старалась держаться поближе к шефу на небольшой платформе с металлическими поручнями. По мере того как они удалялись от двери, свет становился все более тусклым, и вскоре они оказались в полной темноте. Единственным освещением в шифровалке был разве что свет звезд над их головами, едва уловимое свечение проникало также сквозь разбитую стеклянную стену Третьего узла.
Последний шанс. Но мы его упустили. - Не могу с ним не согласиться, - заметил Фонтейн. - Сомневаюсь, что Танкадо пошел бы на риск, дав нам возможность угадать ключ к шифру-убийце. Сьюзан рассеянно кивнула, но тут же вспомнила, как Танкадо отдал им Северную Дакоту.
Из-за чего погибла Меган. Неужели ему предстояло погибнуть по той же причине. Человек неумолимо приближался по крутой дорожке.
Колени у Сьюзан подкосились, и она увидела над головой кружащиеся звезды. ГЛАВА 80 Хейл, крепко сжимая шею Сьюзан, крикнул в темноту: - Коммандер, твоя подружка у меня в руках. Я требую выпустить меня отсюда.
Кто это такие? - переминаясь с ноги на ногу, спросил Бринкерхофф. - Всевидящее око, - сказал Фонтейн, вглядываясь в лица людей, которых он отправил в Испанию.
