Но Танкадо… - размышляла. - С какой стати такой параноик, как Танкадо, доверился столь ненадежному типу, как Хейл. Сьюзан понимала, что теперь это не имеет никакого значения. Нужно немедленно доложить обо всем Стратмору.
Сьюзан словно отключилась от Хейла и всего окружающего ее хаоса. Энсей Танкадо - это Северная Дакота… Сьюзан попыталась расставить все фрагменты имеющейся у нее информации по своим местам. Если Танкадо - Северная Дакота, выходит, он посылал электронную почту самому себе… а это значит, что никакой Северной Дакоты не существует.
