Теперь у нее была другая функция: любой турист, входящий в собор, должен купить билет. Дверь высотой в шесть метров закрылась с гулким стуком, и Беккер оказался заперт в Божьем доме. Он закрыл глаза и постарался сползти на скамье как можно ниже: он единственный в церкви был не в черном. Откуда-то донеслись звуки песнопения.

 Не советую тебе так себя вести, парень, - тихо сказал Беккер. - Я тебя предупредил! - кипятился панк.  - Это мой столик.

Все, кто имел отношение к криптографии, знали, что о АНБ собраны лучшие криптографические умы нашей планеты. Каждую весну, когда частные фирмы начинают охоту за талантливой молодежью, соблазняя ее неприлично высокими окладами и фондовыми опционами в придачу, АНБ внимательно наблюдает за этим, выделяет наиболее подходящих и удваивает предлагаемую сумму. АНБ покупает все, что ему требуется.

Я отправил Дэвида в Испанию. Слова коммандера словно обожгли Сьюзан. - Дэвид в Испании? - Она не могла поверить услышанному.

Он сделал все, что мог, теперь пора ехать домой. Но сейчас, глядя на толпу завсегдатаев, пытающихся попасть в клуб, Беккер не был уверен, что сможет отказаться от дальнейших поисков. Он смотрел на огромную толпу панков, какую ему еще никогда не доводилось видеть.

Давай.

Единственная беда - Халохот глухой, с ним нельзя связаться по телефону. Недавно Стратмор сделал так, что Халохота снабдили новейшей игрушкой АНБ - компьютером Монокль. Себе Стратмор купил Скайпейджер, который запрограммировал на ту же частоту.

 В него попал зараженный файл, сэр. Я абсолютно в этом уверен. Лицо Стратмора побагровело. - Мистер Чатрукьян, такое уже случалось. Нет никакого файла, который мог бы заразить ТРАНСТЕКСТ.

 Королева информации! - приветствовал ее толстяк. Он всегда питал слабость к Мидж Милкен. Умница, да к тому же единственная женщина, не упускавшая случая с ним пококетничать.  - Как твои дела. - Не жалуюсь.

Чтобы увидеть, как какой-то молодой профессор украл его мечту. Стратмор холил и лелеял Сьюзан, оберегал. Он заслужил. И теперь наконец ее получит.

Она загрузила программу Следопыт и, приготовившись отправиться на охоту, взглянула на адрес электронной почты, который вручил ей Стратмор. NDAKOTAARA. ANON. ORG У человека, назвавшегося Северной Дакотой, анонимные учетные данные, но Сьюзан знала, что это ненадолго. Следопыт проникнет в ARA, отыщет Северную Дакоту и сообщит истинный адрес этого человека в Интернете.

Быстрым движением Халохот подтащил его к скамье, стараясь успеть, прежде чем на спине проступят кровавые пятна. Шедшие мимо люди оборачивались, но Халохот не обращал на них внимания: еще секунда, и он исчезнет. Он ощупал пальцы жертвы, но не обнаружил никакого кольца. Еще .
