Faber realises he may be caught before leaving the island and so tries to radio the information about FUSAG directly to Germany. Lucy stops him by short-circuiting the electricity in the cottage. By the logic which had guided his actions throughout his career, Faber should have killed Lucy – but he finds himself unable to do so, being deeply in love with her to the detriment of his mission and of simple self-preservation. Unable to send a radio message, Faber attempts to descend the cliff and swim to the waiting U-boat. Lucy throws a rock down at him, striking him and causing him to lose his balance and fall to his death. An RAF patrol plane then appears and drives the U-boat away. A fictitious radio message is sent with Faber's call code, convincing the Germans that the invasion is targeting Calais. Bloggs comforts the widowed Lucy.
