'But why do you submit?'

'Because I do,' she said, as if this were the inscrutable decree of fate.

And she went on walking, speechless and still slower, as though succumbing to fatigue; he kept by her side, without seeing or hearing anything further, his mind and his senses a blank.

'It is over, my friend—all over. I almost feel as if I were dead. People see my placid face, my invariable calmness, and they must know nothing more; they must never guess the truth. But there is nothing left in here.'

And she tapped her cloak over the place where her heart was. She was unaware what a cruel blow she had dealt the enamoured man in telling him she could never love him. At that hour and that spot she was yielding to one of the melancholy and egoistic outbursts of self-contained spirits; she had lost sight of her companion; she gave herself up to all the private woes of a disenchanted young soul.

'But,' he murmured, 'you have a disinterested, steadfast friend, whose devotion will stand any test; whatever you wish, he wishes; his desire to help you, humbly, secretly, knows no limit——'

And he stopped short, because his voice quavered, because his words choked him, because this, his unspeakable love, threatened to overleap all bounds.

'Thank you—thank you,' she said, a sad smile lighting up her countenance; 'I know it.'

'You cannot—cannot know. I have never told you. I never shall tell you. I never could tell you. I only assure you that it is devotion of the deepest kind. Why reject it? How can you refuse it?'
