She gave them, first, a little German serenade, then a gay bit of Paris music-hall frivolity, and finally her fingers strayed into the accompaniment of a song which she had written for Anthony. It was called "The Wind From the Sea," and it had a haunting refrain.
Diana's thrilling voice rose and fell with the beating cadences. She had sung the song for Anthony on the night before she sailed for Berlin, and when she had finished he had made once more his insistent plea, and she had said, "Wait."
Bettina, next to Anthony, in a corner of the porch, had had a rapturous moment when he had murmured, "How lovely you are to-night," and had laid his hand over hers in the darkness.
But as Diana sang, her joy was suddenly shadowed. Why was Diana singing things that seemed to drag the heart out of one, and why had Anthony taken his hand away, and why was he so still?
Even as she questioned the search-light from the little ferry that plied between the Head and the Neck sent a shaft of blinding radiance across the harbor. Bettina caught a glimpse of her lover's face, and of the longing look in his eyes as they rested on Diana.
Why did Anthony look at Diana like that?
As the insistent question obsessed her, Bettina was conscious of no feeling of jealousy. Her faith in Anthony made impossible any thought that his heart was not wholly hers. She merely coveted the look in his eyes as they rested on another woman.
"Of course it's just the way she sings," she told herself, restlessly. "Why, it almost makes me cry."
