"You have always read to me before just as you have written it. I think that you are not quite so nice to me, Arnold, as you were. I haven't done anything that you do not like, have I? Because I am sure that you are different!"

"You absurd child," I answered, smiling at her as cheerfully as I could. "You are in an imaginative frame of mind to-night."

"It is not that! You look at me differently, you do not seem to want to have me with you so much, and——"

I stopped her. We had reached the fourth floor, where our apartments were. With the key in the lock I turned and faced her for a moment. She was as tall as I, and a certain grace of carriage which she had always possessed, and which had grown with her years, redeemed her completely from the gaucherie of her uncomfortable age. Her features had gained in strength, and lost nothing in delicacy. She wore even her simple clothes with the nameless grace which must surely have come to her from inheritance. I spoke to her then seriously. Yet if I had tried I could not have kept the kindness from my tone.

"Dear Isobel," I said, "if there is any difference—think! A year ago you were a child. To-day you are a woman. You must understand that, side by side with the pleasure of having you with us—the greatest pleasure that has ever come into our lives, Isobel—has come a certain amount of responsibility."

"I am becoming a trouble to you, then!" she exclaimed breathlessly.

"A trouble, Isobel!"

I suppose I weakened for a moment. Some trick of tone or expression must have let in the daylight, for she suddenly held out her hands with a soft little cry. And then as she stood there, her eyes shining, the old delightful smile curving her lips, the door before which she stood was thrown open, and Arthur stood there. He had on his hat and coat, and I saw at once that he was not himself. His cheeks were flushed with anger, and he looked at us with a black frown.

"So you've come back, then!" he exclaimed. "Allan and I got tired of waiting. Just in time to say good-bye, Isobel. I'm off!"

"Off? But where?" she asked, looking at him in surprise.
