He hurried on at a more rapid rate, as if to get away from his thoughts, but his brain persisted in working in the same groove. The possibility of failure obtruded itself with obstinate persistency.
"I'm glad Muller does not doubt either my courage or my honour," he went on. "And really if I fail it will not matter to anyone but myself. I have no ties, neither father nor mother, brother nor sister, wife nor child. I am happy in that——"
Then he moved to the side of the road for a closed landau drawn by a pair of horses to pass him.
"Going to fetch the Hall people from the station very likely," he said to himself, and he turned and looked after the retreating vehicle.
"I wonder if she will return?" and a far-away expression came into his eyes. "I should like to see her again," he went on, "she is wonderfully fresh and natural."
For the rest of the way home he walked very slowly. Now and then he paused, and turned his head, and listened. But the sound of wheels, which he expected to hear, did not break the evening's stillness, nor did he see the face that he hoped to see.
It was nearly a fortnight later that he went out one afternoon on the cliffs alone. A somewhat difficult and complicated problem had unexpectedly presented itself to him, and he fancied he would be better able to see his way through it in the open air than in his workshop or study. Generally speaking, he could think best on his feet, and the sights and sounds of nature, instead of distracting him, soothed him.
It was a warm, drowsy afternoon. The wind slept, and a soft impalpable haze imparted a new mystery to the sea. The tide was coming in slowly and imperceptibly, and rippling like silver bells on the shingly beach. The distant landscape was an impressionist picture in which all the sharp outlines melted into space. The sunshine filtered through a veil of gauze. Half-way to Penwith Cove he sat down on a ledge of rock on the very edge of the cliff, and looked seaward. He saw nothing distinctly, heard no song of the sea. He was too intent on the problem that was baffling his brain.
Suddenly he started and opened his eyes wide. Was it a human voice he heard, or was it merely fancy? He looked round him swiftly in all directions, but no one was in sight. "It was only the cry of a sea-gull, I expect," he said to himself, and he half closed his eyes again. The next moment he was on his feet and staring round him in all directions. "Surely that was a cry for help," he said, and he looked over the edge of the cliff and swept with his eyes the narrow stretch of sand, but there was no one in sight in any direction.
For a moment or two he stood irresolute, listening. "There it is again," he said, with blanched cheeks, and he lay flat on the ground and dragged himself forward slowly till his head and shoulders overhung the cliff.
