The world seemed to have changed by magic while he went back to London. It felt like the breaking up of a frost, when all is warmth and softness and vitality once more. He could have talked to himself, and laughed aloud for very joy.

But Nina went to her room, and cried as she had not cried since she was a little child, shedding tears of mingled sweetness and sorrow, rapture and remorse. Her eyes were opened now in her new-found happiness, and she foresaw the crushing blow that happiness must inflict on the oldest, kindest, dearest of friends.

For the first time in her life she took herself to task and examined her own heart. What a joyous heart it was! And yet how could she be so inhuman as to admit a pleasure which must be cruelly productive of another's pain? Here was a person whom she had known, as it were, but yesterday, and his lightest word or glance had already become dearer to her than the wealth of care and affection which tended her from childhood, which would be about her to her grave. It was infamous! she told herself, and yet it was surpassingly sweet! Yes, she loved this man--this brown-haired, broad-shouldered Mr. Stanmore, of whose existence a fortnight ago she had been perfectly unconscious, and in that love she learned to appreciate and understand the affection loyal, true-hearted Simon lavished on herself. Was he to be sacrificed to this mere stranger? Never! Rather she would sacrifice herself. But the tears flowed faster to think that it would indeed be a sacrifice, an offering up of youth, beauty, hope, happiness for life. Then she dried her eyes, and went down on her knees to pray at her bedside; and so rose up, making certain stern resolutions, which it is only fair to state she afterwards kept--like a woman!

With the view, doubtless, of putting these in practice, she induced Simon to walk with her on the lawn after tea, while the stars were twinkling dimly through a soft, misty sky, and the lazy river lapped and gurgled against the garden banks. He accompanied her, nothing loth, for he too had spent the last hour in hard painful conflict, making, also, stern resolutions, which he kept--like a man! "You found him better," she said, alluding to the cause of his delay in returning home. "I'm so glad. If he hadn't been, you'd have stayed with him all night, I know. Simon, I think you're the best and the kindest person in the world."

Here was an opening. Was she disappointed, or not, that he took so little advantage of it? "We must all help each other, Nina," said he; "that's the way to make life easy and to stifle sorrows, if we have them, of our own."

"You ought never to have a sorrow," she broke in. "You, who always think of others before yourself--you deserve to be so happy. And, Simon, sometimes I think you're not, and it makes me wretched; and I'd do anything in the world to please you; anything, if--if it wasn't too hard a task, you know."

She had been so eager to make her sacrifice and get it over that she hurried inconsiderately to the brink,--then, like a timid bather, stopped short, hesitating--the water looked so cold and dark and deep.

The lightest touch from his hand would have plunged her in, overhead. He would have held it in the fire rather, like the Roman hero, till it shrivelled into ashes.

"My happiness can never be apart from yours," he said, tenderly and sadly. "Yet I think I know now that yours is not entirely bound up in mine. Am I right, Nina?"

"I would do anything in the world for you--anything," she murmured, taking refuge, as we all do at such times, in vain repetition.
