There was a slight sound from his listener, an effort at interruption, but the young man went on without regarding it.
"I did not mean to speak to you so soon. I know you are too young and I expected to wait another year. And certainly you have not given me much encouragement. Sometimes I have not felt that you liked me any better than when first we knew each other. But you can't have completely forgotten what I said to you that day in the woods two years ago. And you know I never change my mind. Now I can't bear to have you go so far away from Woodford without saying again that I care for you, Polly, in spite of our sometimes disagreeing about things and that I will do my level best to make you happy if you, if you——"
But the girl at the piano had risen and Billy now lifted his eager blue eyes to her face. Immediately his expression changed, the hot blood poured into his cheeks, and he moved forward a few steps. Then he stood still with his hands hanging limply at his sides.
For the girl, whose pallor showed even in the semi-darkness of the room and whose lips trembled so that it was difficult for her to command her voice, was not Polly O'Neill! Although her hair was almost equally dark, her chin was less pointed, her lips less scarlet and her whole appearance gentler and more appealing.
"I am sorry," Mollie O'Neill faltered, "I did not understand when you began, Billy, or I should not have listened. But I didn't dream that you and Polly—oh, I didn't suppose that people could quarrel as you do and yet be fond of each other. And you were my friend, Billy, and Polly is my twin sister. I cannot understand why one of you did not tell me how you felt without waiting to have me find out like this." And in spite of her struggle for self-control, there was a break in Mollie O'Neill's soft voice that Billy would have given a great deal never to have heard, and a look on her face which, though he did not entirely understand, he was not soon to forget. She had put out one arm and stood steadying herself against the piano stool like a child who had been unexpectedly hurt and frightened and who wished to run away, yet felt that if she lingered a little longer she might better understand the puzzle.
Nevertheless Billy said nothing for a moment. He was too angry with himself, too worried over the surprise and sorrow in Mollie's eyes, to speak. For they were deeply attached to each other and nothing had come between their friendship since the morning, now almost five years ago, when she had cleverly bandaged up the wound in his head. They had been foolish children then, but so long an intimacy should surely have taught him by this time the difference between the twin sisters. If only the room had not been so dark when he came in, if only he had not been deceived by the crimson coat and cap and by his own excitement!
"There was nothing to tell you before, Mollie, at least nothing that counts," Billy began humbly. "Sometimes I have wanted to explain to you my feeling for Polly. We do quarrel and she makes me angrier than anyone I know in the world, and yet somehow I can't forget her. And I like being with her always, even when she is in a bad temper. Then I don't wish her to go on the stage. I think it a horrid profession, and Polly is not strong enough. I would do anything that I could to prevent it. But you see, Mollie, I have no reason to believe that Polly cares for me; though now and then she has seemed to like me better than she once did. Still I am determined to try whatever means I can to keep her away from this Miss Adams' influence. For if once Polly leaves Woodford with her, the old Polly whom we both know and love will never come back to us again." And Billy appeared so disconsolate and so unlike his usual confident, masterful self, that Mollie smiled at him, a little wistfully it is true, but in a perfectly friendly and forgiving fashion.
"I'll go and find whether Polly has come home," she answered. "I ran in for a moment to call on Miss Adams and found that Polly had left there half an hour before. I wore her old coat and cap, so I think she must be dressed in her best clothes and paying visits somewhere." And Mollie laid a hand lightly on her friend's arm.
"Don't be discouraged at whatever Polly says to you," she begged. "You know that she may be angry at the idea of your opposing her having this European trip with Miss Adams. But she is not going. Mother is positive and Polly will not do more than ask for permission since there is a whole year more before her promise ends."
