 - Он сказал, что на кольце были выгравированы какие-то буквы. - Буквы. - Да, если верить ему - не английские.  - Стратмор приподнял брови, точно ждал объяснений. - Японские иероглифы.

 Кто тебе это сказал? - спросил он, и в его голосе впервые послышались металлические нотки. - Прочитал, - сказал Хейл самодовольно, стараясь извлечь как можно больше выгоды из этой ситуации.  - В одном из ваших мозговых штурмов. - Это невозможно. Я никогда не распечатываю свои мозговые штурмы.

Его визуальный монитор - дисплей на жидких кристаллах - был вмонтирован в левую линзу очков. Монокль явился провозвестником новой эры персональных компьютеров: благодаря ему пользователь имел возможность просматривать поступающую информацию и одновременно контактировать с окружающим миром. Кардинальное отличие Монокля заключалось не в его миниатюрном дисплее, а в системе ввода информации. Пользователь вводил информацию с помощью крошечных контактов, закрепленных на пальцах. Контакты соединялись в определенной последовательности, которую компьютер затем расшифровывал и переводил на нормальный английский. Киллер щелкнул миниатюрным тумблером, и очки превратились в дисплей.

Мужчина смотрел на него недовольно. - Was wollen Sie. Что вам .

Британского флага нигде не было. Ясно, что ему не удастся влиться в это море, которое раздавит его, как утлую лодчонку. Рядом с ним кого-то рвало. Хорошенькая картинка.

Ему не было нужды выискивать Беккера в толпе, выходящей из церкви: жертва в ловушке, все сложилось на редкость удачно. Нужно только выбрать момент, чтобы сделать это тихо. Его глушитель, самый лучший из тех, какие только можно было купить, издавал легкий, похожий на покашливание, звук. Все будет прекрасно. Приближаясь к пиджаку защитного цвета, он не обращал внимания на сердитый шепот людей, которых обгонял.
