It seemed as though Mr. Leighton were the young, inexperienced person, and that Isobel was the one to impart knowledge.

"In justice to Mr. Meredith, I do not know in the slightest what he thought. That is where my case loses its point. I ought to have known. I certainly, of course, think that I ought to know now."

"Oh," said Isobel. She rose very simply and looked as placid as a lake on a calm morning. "That is very simple. Mr. Meredith intends to marry me whenever I give him the opportunity."

Mr. Leighton was thunderstruck. At the bottom of his mind, he was thankful now that "his girls" were away. Memories of the stumbling block which the existence of Robin's sister had before occasioned made him ask first, "Does Miss Meredith know?"

He spoke in quite a calm manner. It frustrated Isobel for the moment, who had expected an outburst. She wavered slightly in her answer.

"I don't know," she said.

Mr. Leighton moved impatiently.

"That is just it," he said. "This young man makes tentative arrangements and leaves out the important parties to it. Miss Meredith is quite capable of upsetting her brother's plans. Do you know it?"

It seemed that Isobel did. It seemed that Miss Meredith was the one person who could ruffle her. From that day of negligently answering and partly snubbing her in the train, Isobel had showed a side of cool indifference to Miss Meredith.

"I want you to know, Uncle, that I shall not consider Miss Meredith in the slightest."
