Стратмор полагал, что у него еще есть время. Он мог отключить ТРАНСТЕКСТ, мог, используя кольцо, спасти драгоценную базу данных. Да, подумал он, время еще. Он огляделся - кругом царил хаос. Наверху включились огнетушители. ТРАНСТЕКСТ стонал. Выли сирены.

Стратмор даже не пошевелился. - Коммандер. Нужно выключить ТРАНСТЕКСТ. У нас… - Он нас сделал, - сказал Стратмор, не поднимая головы.  - Танкадо обманул всех. По его тону ей стало ясно, что он все понял.

Дэвид грустно вздохнул: - Потому-то я и звоню. Речь идет о нашей поездке. Нам придется ее отложить. - Что-о? - Сьюзан окончательно проснулась. - Прости. Я срочно уезжаю.

Ему казалось, что с него сорваны все внешние покровы. Не было ни страха, ни ощущения своей значимости - исчезло. Он остался нагим - лишь плоть и кости перед лицом Господа.

На фотографии она была изображена наклонившейся над постелью, в одних трусиках. Как выяснилось, кто-то из криптографов сосканировал фотографию из порножурнала и приставил к телу головы модели голову Сьюзан. Получилось очень даже правдоподобно. К несчастью для того, кто это придумал, коммандер Стратмор не нашел в этой выходке ничего забавного.

Сьюзан в испуге взглянула на Хейла. Он стоял с безучастным видом, словно происходящее его никак не касалось. И это понятно, - подумала.  - Никакой вирус Хейла не волнует, он ведь отлично знает, что происходит с ТРАНСТЕКСТОМ. Но Чатрукьян стоял на .

Тут все совпадает. Он решил, что мы добрались до него и, вероятно, отравили - ядом, вызывающим остановку сердца.

Он не услышал ее крика, когда ударил ее, он даже не знал, кричала ли она вообще: он оглох, когда ему было всего двенадцать лет от роду. Человек благоговейно потянулся к закрепленной на брючном ремне батарее: эта машинка, подарок одного из клиентов, подарила ему новую жизнь. Теперь он мог принимать заказы в любой точке мира.

Приходи поиграть. - На улице еще темно, - засмеялся. - А-ах, - сладко потянулась.  - Тем более приходи. Мы успеем выспаться перед поездкой на север.

Сьюзан осталась стоять. - Коммандер, если вы все еще горите желанием узнать алгоритм Танкадо, то можете заняться этим без. Я хочу уйти. Стратмор глубоко вздохнул.
