В одно мгновение Сьюзан все стало ясно. Когда Стратмор загрузил взятый из Интернета алгоритм закодированной Цифровой крепости и попытался прогнать его через ТРАНСТЕКСТ, цепная мутация наткнулась на фильтры системы Сквозь строй. Горя желанием выяснить, поддается ли Цифровая крепость взлому, Стратмор принял решения обойти фильтры. В обычных условиях такое действие считалось бы недопустимым.

В дальнем конце палаты появилась медсестра и быстро направилась к. - Хоть что-нибудь, - настаивал Беккер. - Немец называл эту женщину… Беккер слегка потряс Клушара за плечи, стараясь не дать ему провалиться в забытье. Глаза канадца на мгновение блеснули. - Ее зовут… Не отключайся, дружище… - Роса… - Глаза Клушара снова закрылись.

На центральном экране прямо под извещением об ошибке ВР представила зрителям ужасающую картину. По мере того как рушилась третья защитная стенка, полдюжины черных линий, эти хакеры-мародеры, устремлялись вперед, неуклонно продвигаясь к сердцевине. С каждым мгновением появлялась новая линия, а за ней - следующая.

Желтый сигнал тревоги вспыхнул над шифровалкой, и свет, пульсируя, прерывистыми пятнами упал налицо коммандера.

Тишина шифровалки взорвалась сигналом тревоги, доносившимся из служебного помещения ТРАНСТЕКСТА. Сьюзан и Стратмор в недоумении посмотрели друг на друга. - Что это? - вскрикнула Сьюзан между сигналами. - ТРАНСТЕКСТ перегрелся! - сказал Стратмор. В его голосе слышалось беспокойство.

ГЛАВА 77 Стратмор остановился на площадке у своего кабинета, держа перед собой пистолет. Сьюзан шла следом за ним, размышляя, по-прежнему ли Хейл прячется в Третьем узле. Свет от монитора Стратмора отбрасывал на них жутковатую тень. 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.

Стоявшая перед ней задача была проста: войти в компьютер Хейла, найти ключ и уничтожить все следы его переписки с Танкадо. Нигде не должно остаться даже намека на Цифровую крепость. Сьюзан снова завладели прежние сомнения: правильно ли они поступают, решив сохранить ключ и взломать Цифровую крепость. Ей было не по себе, хотя пока, можно сказать, им сопутствовала удача. Чудесным образом Северная Дакота обнаружился прямо под носом и теперь попал в западню.

Наш гражданин был сегодня доставлен в вашу больницу. Я хотел бы получить информацию о нем, с тем чтобы посольство могло оплатить его лечение.

 Коммандер, - вмешалась Сьюзан, - я хотела бы поговорить… Стратмор жестом заставил ее замолчать. Глаза его неотрывно смотрели на Чатрукьяна. - В него попал зараженный файл, сэр. Я абсолютно в этом уверен.

Однако тот не подавал никаких признаков жизни. Сьюзан перевела взгляд на помост перед кабинетом Стратмора и ведущую к нему лестницу. - Коммандер. Молчание. Тогда она осторожно двинулась в направлении Третьего узла.

Беккер поблагодарил. Отпил глоток и чуть не поперхнулся. Ничего себе капелька. В голове у нее стучало. Повернувшись, она увидела, как за стеной, в шифровалке, Чатрукьян что-то говорит Хейлу.

С интервалом в три минуты была зарегистрирована вторая серия команд запирания-отпирания. Согласно регистру, кто-то открывал ее компьютер, пока ее не было в комнате. Но это невозможно.

 - Сегодня не его дежурство. - Похоже, что-то стряслось, - сказала Сьюзан.  - Наверное, увидел включенный монитор. - Черт возьми! - выругался коммандер.

Он остался в живых. Это было настоящее чудо. Священник готовился начать молитву.

Я грохнулся на землю - такова цена, которую приходится платить добрым самаритянам. Вот запястье в самом деле болит. Болван этот полицейский.
