- Танкадо потребовал ТРАНСТЕКСТ. - ТРАНСТЕКСТ. - Да.

Какая разница? - огрызнулся светловолосый. - Позвольте вам сразу кое-что объяснить, - сказал директор. Секунду спустя оба, залившись краской, делали доклад директору Агентства национальной безопасности.

Я скажу вам, кто его сегодня сопровождает, и мы сможем прислать ее к вам завтра. - Клаус Шмидт, - выпалил Беккер имя из старого учебника немецкого. Долгая пауза. - Сэр… я не нахожу Клауса Шмидта в книге заказов, но, быть может, ваш брат хотел сохранить инкогнито, - наверное, дома его ждет жена? - Он непристойно захохотал.
