He could not see the singer; all he saw was the circle of black night, the faint lines of his boat a shade blacker against it, and just ahead the white glimmer of the wall. The voice, low and sweet, came out of the darkness like a bird flying through a desert--a living thing amid death. Mitsos stood perfectly still, strangely and bewilderingly excited. Then he took up his oar and turned the boat's head round, rowed a few strokes out, and waited again. But the voice had ceased. He felt somehow unaccountably shy, as if he had intruded into another's privacy; but having intruded, he was determined to make his presence known. So just as the sail caught the wind again he stood up in the stern, and in his boyish voice answered the unseen singer with the second verse: "Dig we deep, the summer's here; Saw we not among the eaves Summer's messenger appear, Swallows flitting here and there, Through the budding almond leaves?" The boat bent over to the wind, the white line streaked the water, and he hissed off into the night again. He sat down, let go of the tiller, and let the boat run on by itself. He had never known that that common country song was beautiful till he had heard a voice out of the darkness sing it--a voice low, sweet, soft, which might have been the darkness itself made audible. Who was this woman? How did she, a Greek, come to be in the house of a Turk? Then with a flash of awakened memory he brought to mind the evening when he and Nicholas had sailed home after fishing; how a man came up and struck a woman who was leaning on the sea-wall; how she had cried out and said, in Greek, "What was that for?" The flapping of the sail in the last breath of the wind roused him and he looked up; the breeze had died out, and he was floating in the middle of a shell of blackness. He had no idea where he was until he saw the lights of Nauplia, where he least expected them, on the left of the boat instead of behind him, dim, and far away. For his craft, left to itself, had of course run straight before the land-breeze out into the mouth of the gulf, and now the breeze had died out and he was miles from the land. That did not trouble him much; fishing was a minor consideration, and spending the night in the boat was paid for by a shrug of the shoulders. He wanted one thing only--to get back to the white glimmering wall, to the voice from the darkness.
