"Good heavens, Kath!" he said, as he took up the book gingerly, treating it as if it were an explosive, "what on earth have you got here? Didn't know you went in for chemistry too. What in the name of all the Cæsars does an asymmetric atom of carbon mean? I never heard of the beasty before."

"Nor did I," answered Katharine, with a hopeless smile. That book had really been too much for her. Yet she loved to have it. It was only one of the many scientific books she had been buying since she returned from Norway. Willy saw them on the shelf. They were nearly all lives of great chemists, or handbooks on chemistry. He examined them one by one, and then turned to her.

"Kath," he said gently, "don't forget that you trusted me before."

[CHAPTER II.]

But Katharine could tell him nothing; and he, seeing that she wished to keep her own counsel, asked her nothing. But he insisted that she should spend some of her leisure time in his home; and when she was there, he tried to be, so he said, his brightest and quickest self, in order to cheer her and chase away all bad effects of business and culture. One Sunday when she went, he was in great spirits. He had sold his picture of Mary, Queen of Scots.

"You now see the advantage of working slowly," he said in a grandiose manner. "I have taken sixteen years of continuous thought and study to paint that immortal picture. One year less would not have done the trick! By Jove! Kath, won't that look well in the papers? All the fellows I know paint six pictures a-year, or write twelve books a-month. But I, Willy Tonedale, the much-abused slow one, have painted one picture in sixteen years. I admit that an artist does not become rich on one picture in sixteen years. But reflect, I beg you, on the thought, the patient historic research involved, and the reward reached after long, long years of toil! What a good thing I didn't die over that pneumonia affair! I should have gone spark out if you had not come over from Norway and called me back to life. I began to get better directly you returned, Kath, and directly mother left off engaging the Christian Science creature to heal me. Of course mother makes out that I was cured by Christian Science; but I say I was cured by Katharine Science. Smart of me, isn't it? But then I am getting awfully sharp! I'm amazed at myself. Seems to me, though, that as I become sharper, every one I know becomes duller. Margaret is quite flattened out with Causes, and wears sandals. Mother is a weird mixture of depression and superiority from Christian Science and the Salisbury treatment; even my belovèd cousin Julia looks devitalised and chastened. She only speaks in a whisper, and her face is the colour of artichoke-soup. She says she had a fright in Norway."

Katharine laughed.

"I should think she did have a fright in Norway," Katharine said, brightening up. And she told Willy something of what had happened up at the Saeter.

"And what are you going to do to her when you see her?" he asked.

"Nothing," Katharine answered. "I do not mind what she thinks of me. I know you do not think I ever behaved badly to you."
