Он быстро нацарапал на программке ответ и протянул Сьюзан: LDSNN Сьюзан, прочитав, просияла. ME TOO, что означало: Я. Беккер расхохотался. Он дожил до тридцати пяти лет, а сердце у него прыгало, как у влюбленного мальчишки. Никогда еще его не влекло ни к одной женщине.

Все знали про Северную Дакоту. Танкадо рассказал о своем тайном партнере в печати. Это был разумный шаг - завести партнера: даже в Японии нравы делового сообщества не отличались особой чистотой. Энсей Танкадо не чувствовал себя в безопасности. Лишь один неверный шаг слишком уж настойчивой фирмы, и ключ будет опубликован, а в результате пострадают все фирмы программного обеспечения.

 Роса? - Беккер сжал руку Клушара. Старик застонал. - Он называл ее… - Речь его стала невнятной и едва слышной.

Сьюзан посмотрела на него и подумала о том, как жаль, что этот человек, талантливый и очень ценный для АНБ, не понимает важности дела, которым занимается агентство. - Грег, - сказала она, и голос ее зазвучал мягче, хотя далось ей это нелегко.  - Сегодня я не в духе. Меня огорчают твои разговоры о нашем агентстве как каком-то соглядатае, оснащенном современной техникой. Эта организация создавалась с единственной целью - обеспечивать безопасность страны.

 - Она застонала. Все четко, ясно и. Танкадо зашифровал Цифровую крепость, и только ему известен ключ, способный ее открыть.

 На руке умершего было золотое кольцо. Я хочу его забрать. - У м-меня его. Беккер покровительственно улыбнулся и перевел взгляд на дверь в ванную.

Запах показался ей смутно знакомым, и эта мысль пронзила ее холодом. Сьюзан представила себе Хейла в западне, в окутанной паром ловушке. Может быть, он что-нибудь поджег.

Беккер не мог ждать. Он решительно поднял трубку, снова набрал номер и прислонился к стене. Послышались гудки.
