Альфонсо Тринадцатый. Очень хорошо, прямо сейчас туда загляну. Спасибо, что помогли. Дэвид Беккер повесил трубку. Альфонсо XIII. Он усмехнулся. Просто надо уметь задавать вопросы… Минуту спустя незаметная фигура проследовала за Беккером по калле Делисиас в сгущающейся темноте андалузской ночи.

Он и так скоро уйдет. Код, не поддающийся взлому. Сьюзан вздохнула, мысли ее вернулись к Цифровой крепости. Она не могла поверить, что такой алгоритм может быть создан, но ведь доказательство налицо - у нее перед глазами.

Мысли ее по-прежнему возвращались к сотруднику лаборатории систем безопасности, распластавшемуся на генераторах. Она снова прошлась по кнопкам. Они не реагировали.

Ее молитва была проста: она просила Бога защитить любимого человека.
