Провал Стратмора дорого стоил агентству, и Мидж чувствовала свою вину - не потому, что могла бы предвидеть неудачу коммандера, а потому, что эти действия были предприняты за спиной директора Фонтейна, а Мидж платили именно за то, чтобы она эту спину прикрывала. Директор старался в такие дела не вмешиваться, и это делало его уязвимым, а Мидж постоянно нервничала по этому поводу. Но директор давным-давно взял за правило умывать руки, позволяя своим умным сотрудникам заниматься своим делом, - именно так он вел себя по отношению к Тревору Стратмору.

К рабочему кабинету Стратмора, именуемому аквариумом из-за стеклянных стен, вела узкая лестница, поднимавшаяся по задней стене шифровалки.

 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.
