Это было радостное избавление от вечного напряжения, связанного с ее служебным положением в АНБ. В один из прохладных осенних дней они сидели на стадионе, наблюдая за тем, как футбольная команда Рутгерса громит команду Джорджтауне кого университета. - Я забыла: как называется вид спорта, которым ты увлекаешься? - спросила Сьюзан.  - Цуккини. - Сквош, - чуть не застонал Беккер. Сьюзан сделала вид, что не поняла.

Да, сэр, - сказала Мидж. - Потому что Стратмор обошел систему Сквозь строй? - Фонтейн опустил глаза на компьютерную распечатку. - Да, - сказала .

Медсестра была уже совсем близко и что-то кричала Беккеру по-испански, но он ничего не слышал. Его глаза не отрывались от губ Клушара. Он еще раз сжал его руку, но тут наконец подбежала медсестра. Она вцепилась Беккеру в плечо, заставив его подняться - как раз в тот момент, когда губы старика шевельнулись.

Чего-нибудь выпьете. - Спасибо. Я лишь хотел спросить, есть ли в городе клубы, где собираются молодые люди - панки. - Клубы.

Повернувшись, он направился через фойе к выходу, где находилось вишневое бюро, которое привлекло его внимание, когда он входил. На нем располагался щедрый набор фирменных открыток отеля, почтовая бумага, конверты и ручки. Беккер вложил в конверт чистый листок бумаги, надписал его всего одним словом: Росио - и вернулся к консьержу. - Извините, что я снова вас беспокою, - сказал он застенчиво.

Вдруг она ощутила страшное одиночество. Стратмор увидел пятна крови на ее блузке и тотчас пожалел о своей вспышке. - Боже, Сьюзан, с тобой все в порядке. Она промолчала. Не нужно было так резко с ней говорить.

Он подумал было попросить пилота радировать Стратмору, чтобы тот передал его послание Сьюзан, но не решился впутывать заместителя директора в их личные дела. Сам он трижды пытался связаться со Сьюзан - сначала с мобильника в самолете, но тот почему-то не работал, затем из автомата в аэропорту и еще раз - из морга. Сьюзан не было дома. Он не мог понять, куда она подевалась.

Он помнил, что сказал Клушар: немец нанял девушку на весь уик-энд. Беккер вышел из телефонной будки на перекрестке калле Саладо и авениды Асунсьон. Несмотря на интенсивное движение, воздух был наполнен сладким ароматом севильских апельсиновых деревьев.

Она расхохоталась. - Я же сказала вам, что ревела навзрыд, опоздав на самолет. Он перевел взгляд на слова, нацарапанные на ее руке. Она смутилась.

Мы к нему не прикасались.
