The Voice rose and sank and soared again, drawing nearer and nearer. It was joyous and unrestrained, and there was youth in it, the touch of spring and the breath of flowers. The music was Lecocq's, that is to say, French; but the tongue was of a country which Hillard knew to be the garden of the world. Presently he observed a shadow emerge from the yellow mist, to come within the circle of light, which, faint as it was, limned in against the nothingness beyond the form of a woman. She walked directly under his window. As the invisible comes suddenly out of the future to assume distinct proportions which either make or mar us, so did this unknown cantatrice come out of the fog that night and enter into Hillard's life, to readjust its ambitions, to divert its aimless course, to give impetus to it, and a directness which hitherto it had not known. "Ah!" He leaned over the sill at a perilous angle, the bright coal of his pipe spilling comet-wise to the area-way below. He was only subconscious of having spoken; but this syllable was sufficient to spoil the enchantment. The Voice ceased abruptly, with an odd break. The singer looked up. Possibly her astonishment surpassed even that of her audience. For a few minutes she had forgotten that she was in New York, where romance may be found only in the book-shops; she had forgotten that it was night, a damp and chill forlorn night; she had forgotten the pain in her heart; there had been only a great and irresistible longing to sing. Though she raised her face, he could distinguish no feature, for the light was behind. However, he was a man who made up his mind quickly. Brunette or blond, beautiful or otherwise, it needed but a moment to find out. Even as this decision was made he was in the upper hall, taking the stairs two at a bound. He ran out into the night, bareheaded. Up the street he saw a flying shadow. Plainly she had anticipated his impulse and the curiosity behind it. Even as he gave chase the shadow melted in the fog, as ice melts in running waters, as flame dissolves in sunshine. She was gone. He cupped his ear with his hand; in vain, there came no sound as of pattering feet; there was nothing but fog and silence. "Well, if this doesn't beat the Dutch!" he murmured. He laughed disappointedly. It did not matter that he was three and thirty; he still retained youth enough to feel chagrined at such a trivial defeat. Here had been something like a genuine adventure, and it had slipped like water through his clumsy fingers. "Deuce take the fog! But for that I'd have caught her."
