Проехав еще полмили, Сьюзан подверглась той же процедуре перед столь же внушительной оградой, по которой был пропущен электрический ток. Давайте же, ребята… уже миллион раз вы меня проверяли. Когда она приблизилась к последнему контрольно-пропускному пункту, коренастый часовой с двумя сторожевыми псами на поводке и автоматом посмотрел на номерной знак ее машины и кивком разрешил следовать. Она проехала по Кэнин-роуд еще сотню метров и въехала на стоянку С, предназначенную для сотрудников. Невероятно, - подумала она, - двадцать шесть тысяч служащих, двадцатимиллиардный бюджет - и они не могут обойтись без меня в уик-энд. Она поставила машину на зарезервированное за ней место и выключила двигатель. Миновав похожую на сад террасу и войдя в главное здание, она прошла проверку еще на двух внутренних контрольных пунктах и наконец оказалась в туннеле без окон, который вел в новое крыло.

Однажды в компьютере случился сбой, причину которого никто не мог установить. После многочасовых поисков ее обнаружил младший лаборант.

 Ладно, - процедил Стратмор.  - Итак, даже в самых экстремальных условиях самый длинный шифр продержался в ТРАНСТЕКСТЕ около трех часов.

 - Давайте ближе к сути дела. Агент Колиандер нажал несколько кнопок, и кадры стали сменяться быстрее. Люди на подиуме с нетерпением ждали, когда на экране появится их бывший сослуживец Энсей Танкадо. Ускоренное проигрывание видеозаписи придавало изображению некоторую комичность.

 Неужели это так заметно. - Как ее зовут? - Женщина лукаво подмигнула. - Меган, - сказал он печально.

 Вот что нам надо сделать.  - Стратмор начал спокойно излагать свой план.  - Мы сотрем всю переписку Хейла с Танкадо, уничтожим записи о том, что я обошел систему фильтров, все диагнозы Чатрукьяна относительно ТРАНСТЕКСТА, все данные о работе компьютера над Цифровой крепостью, одним словом - .
