All at once, a plan to accomplish this formulated itself in her mind. He had wanted to "smash the piano." Well, he should never want that again. She would show him that her music was not going to stand between them--that she was willing to share it with him. She would talk to him about it, get him to understand something of what it meant to her, and when the concerto was quite finished, she would invite him into the West Parlour to listen to it. It was nearing completion--another week's work and what Sandy laughingly termed her "magnum opus" would be finished. Of course Roger wouldn't be able to give her a musician's understanding of it, but he would certainly appreciate the fact that she had played it to him first of anyone. It would go far to heal that resentful jealousy if she "shared" the concerto with him. He would never again feel that she was keeping him outside the real interests of her life. Probably, later on, when it was performed by a big London orchestra, under the auspices of one of the best-known conductors of the day--who happened to be a particular friend of Nan's and a staunch believer in her capacity to do good work--Roger would even begin to take a quaint kind of pride in her musical achievements. What she purposed would involve a good deal of pluck and sacrifice. For it takes both of these to reveal yourself, as any true musician must, to an audience of one with whom you are not utterly in sympathy. But if by this road she and Roger took one step towards a better understanding, towards that comradeship which was all that she could ever give him, then it would have been worth the sacrifice. Gradually the stony look of despair lifted from her face, and a new spirit of resolution took possession of her. She was not the only person in the world who had to suffer. There were others, Peter amongst them, who were debarred by circumstances from finding happiness, and who went on doing their duty unflinchingly. It was only she who had failed--letting Roger bear the cost of her mistake. She had promised to marry him when it seemed the only way out of the difficulties which beset her, and now she was not honouring that promise. While Peter Mallory was still waiting quietly for the wife he no longer loved to come back to him--keeping the door of his house open to her whenever she should choose to claim fulfilment of the pledges he had given the day he married her. Nan leaned her head against the window-pane, realising that, whatever Roger's faults might he, she, too, had fallen short. "Our troth, Nan. Hang on to it--_hard_, when life seems a bit more uphill than usual."
