He began to realize the yearning of the suicide for the peace beyond life. How easy to solve all problems. How easy to rid oneself of the duties, the harassing, cruel duties imposed by the Creator of all life. The soft murmur of the breaking swell upon the beach below. One plunge beneath that shimmering surface and--nothing. In that instant there flashed through his mind a memory of just such another sea. The perfect summer sea. The great ship, one of the wonders of the age. A stealing trail of foam across the glass-like surface. An explosion. Then fifteen hundred souls solve the problem of that--nothing! Ah, that was it. That was the Danger. He knew. Every thinking human being knew that if Germany had begun war with a fleet of some three or four hundred submarines, three weeks would have terminated the war so far as Britain was concerned. He moved over on to his side, and his movement was a further expression of nervous tension. He propped his head upon one hand with his eyes fixed on the vague horizon beyond which the Teutonic giant was peacefully slumbering, and his thought was spoken aloud. "Is he slumbering?" he asked of the sea. "Is he? Will he ever sleep again? No, I think not. Not at least while there is a chance that his intelligence behind the machine can render an island home untenable." "Night claims from the overburdened soul the truth which daylight is denied." Ruxton Farlow sat up with a jolt. His dark, searching eyes were turned from the sea. They were turned in the direction whence the voice, which had answered him, had proceeded. In the brilliant moonlight he saw the outline of a figure standing upon the footpath which ran parallel to the coast-line. The figure was not quite distinct, but it was clearly a woman's, which corroborated the conviction he had received at the sound of the voice. "But for once she has betrayed her--trust," he said, and a feeling of irritation swept over him that he had permitted himself to respond to the challenge of this stranger, who was probably something in the nature of one of life's vagrants, wandering homeless over the deserted ways of the countryside. Then he discovered to his further annoyance that his response had brought forth its logical result. The figure was moving towards him, and as it drew near he became aware of that delightful feminine rustle which no man ever yet found unseductive. The woman made no verbal reply until she was standing before him. Ruxton was still sitting on the heather, but his eyes were wide with astonished admiration, and his clean-shaven lips were parted, which added to his whole expression of incredulous amazement.
