Но Стратмор не дал ей договорить. - Сьюзан, это же абсолютно ясно. Танкадо выгравировал ключ Цифровой крепости на кольце. Золото долговечно. Что бы он ни делал - спал, стоял под душем, ел, - ключ всегда при нем, в любую минуту готовый для опубликования.

Однажды, в первый год своей работы в агентстве, Сьюзан заглянула в комнату новых криптографов за какими-то бумагами. Уже направляясь к двери, она увидела свое фото на доске объявлений и едва не лишилась чувств. 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 потеряла дар речи. Он пристально посмотрел на нее и постучал ладонью по сиденью соседнего стула. - Садись, Сьюзан. Я должен тебе кое-что сказать.  - Она не пошевелилась.

Однако в дверях появился Стратмор. Бледная, жуткая в тусклом свете мониторов фигура застыла, грудь шефа тяжело вздымалась. - Ком… мандер! - вскрикнула она от неожиданности.  - Хейл в Третьем узле. Он напал на .

 Сьюзан, - проговорил он, стараясь сдержать раздражение, - в этом как раз все. Мне было нужно… Но тигрица уже изготовилась к прыжку. - В вашем распоряжении двадцать тысяч сотрудников.

 - О… Боже ты мой… Фонтейн тоже все понял. Брови его поползли вверх. Он был потрясен. Мидж и Бринкерхофф охнули в унисон. - Ну и чертовщина.


Первый - с личного терминала коммандера, запертого в его кабинете, и он, конечно, исключался. Второй - с помощью ручного выключателя, расположенного в одном из ярусов под помещением шифровалки. Чатрукьян тяжело сглотнул. Он терпеть не мог эти ярусы. Он был там только один раз, когда проходил подготовку.

 - Ты слышала, как я швырнул на верхнюю площадку свои ботинки. Сьюзан вдруг поняла, что смеется и плачет одновременно. Коммандер спас ей жизнь.

А потом мы позвоним директору. - Замечательно.
