Then her mood changed altogether. The laughter died away, the very look of it faded from her face. She stood up and faced Harry Luttrell. In the depths of her eyes there appeared a sudden gravity, a certain wistfulness, almost a regret.

She spoke simply:

"Iram indeed is gone with all his rose,
And Jamshyd's seven-ringed cup—where, no one knows!
But still a ruby kindles in the vine,
And many a garden by the water blows."

She had the air of one saying good-bye to many pleasant follies which for long had borne her company—and saying good-bye with a sort of doubt whether that which was in store for her would bring a greater happiness.

Harry Luttrell had no answer, and no very distinct comprehension of her mood. But he was stirred by it. For a little while they looked at one another without any words. The air about them in that still hall vibrated with the emotions of violins. Joan Whitworth was the first to break the dangerous silence.

"I am afraid that up till now, what I have liked, I have liked tremendously, but I have not always liked it for very long. You will remember that in pity, won't you?" she said lightly.

Harry Luttrell was quick to catch her tone.

"I shall remember it with considerable apprehension if I am fortunate enough ever to get into your good books." His little speech ended with a gasp. The letter which he was holding carelessly in his fingers had almost slipped from them into the locked letter box.

Joan crossed to where he stood.

"That's all right," she said. "You can post your letter there. The box is cleared regularly."
