Испанская церковь. Беккер отлично знал, что в Испании только одна церковь - римско-католическая. Католицизм здесь посильнее, чем в самом Ватикане. - У нас, конечно, не все его тело, - добавил лейтенант.  - Solo el escroto.

 Это объявление войны, - прошептал Фонтейн срывающимся голосом. Джабба покачал головой: - Лично я сомневаюсь, что Танкадо собирался зайти так. Я думаю, он собирался оставаться поблизости и вовремя все это остановить. Глядя на экран, Фонтейн увидел, как полностью исчезла первая из пяти защитных стен. - Бастион рухнул! - крикнул техник, сидевший в задней части комнаты.  - Обнажился второй щит. - Нужно приступать к отключению, - настаивал Джабба.

 - На это уйдет полчаса. К тому времени все уже рухнет. Джабба открыл рот, готовый что-то сказать, но тут его буквально парализовал душераздирающий крик. Все повернули головы к Сьюзан Флетчер, которая выпрямилась и поднялась со стула. Лицо ее побелело, глаза не отрываясь смотрели на застывший кадр, демонстрировавший неподвижное тело Дэвида Беккера, залитое кровью, брошенное на пол мини-автобуса. - Вы его убили! - крикнула .

 Я не хочу никоим образом нарушать покой директора и говорить с ним о кризисе, в то время как он не в состоянии предпринять хоть что-нибудь. Сьюзан понимала, что коммандер прав. Даже в такие моменты ему удавалось сохранять ясность рассудка. - А вы не думали о том, чтобы позвонить президенту. Стратмор кивнул: - Думал. Но решил этого не делать. Сьюзан так и подумала.

 Без воска? - тихо спросила она, обнимая. - Без воска.

 Я понимаю, - сказал.  - Извините за беспокойство. Повернувшись, он направился через фойе к выходу, где находилось вишневое бюро, которое привлекло его внимание, когда он входил.

Это произвело на дешифровщиков впечатление, но тем не менее Беккер продолжал переводить знаки вразнобой, а не в той последовательности, в какой они были расположены в тексте. - Это для вашей же безопасности, - объяснил Морант.  - Вам незачем знать, что вы переводите. Беккер засмеялся. И увидел, что никто даже не улыбнулся, когда текст был наконец расшифрован.

Я видел схему. - Да мы уже пробовали, - задыхаясь, сказала Сьюзан, пытаясь хоть чем-то помочь шефу.  - Он обесточен.
