Clarity is the first and most important job of any interface.

Вы сейчас же отпустите мисс Флетчер, или я вызову службу безопасности и засажу вас в тюрьму до конца ваших дней. - Вы этого не сделаете, - как ни в чем не бывало сказал Хейл.  - Вызов агентов безопасности разрушит все ваши планы. Я им все расскажу.  - Хейл выдержал паузу.

Фонтейн пришел к выводу, что Стратмор в полном порядке, что он трудится на сто десять процентов, все так же хитер, умен и в высшей степени лоялен, впрочем - как. Лучшее, что мог сделать директор, - не мешать ему работать и наблюдать за тем, как коммандер творит свое чудо. Стратмор разработал план… и план этот Фонтейн не имел ни малейшего намерения срывать. ГЛАВА 75 Пальцы Стратмора время от времени касались беретты, лежавшей у него на коленях. При мысли о том, что Хейл позволил себе прикоснуться к Сьюзан, кровь закипела в его жилах, но он помнил, что должен сохранять ясную голову, Стратмор с горечью признал, что сам отчасти виноват в случившемся: ведь именно он направил Сьюзан в Третий узел.

Он заместитель директора Агентства национальной безопасности, а сегодня все, что он делает, важно, как .

 Самое разрушительное последствие - полное уничтожение всего банка данных, - продолжал Джабба, - но этот червь посложнее. Он стирает только те файлы, которые отвечают определенным параметрам.
