Patty smiled again, remembering that she had had a reason to smile as she danced, and she wondered why Philip didn’t appear.

But he didn’t, and, except that she had seen him so clearly in the mirror, and he had asked her, silently but unmistakably, not to divulge the fact of his presence, she would have thought she only imagined him there in the doorway.

“You dance wonderfully well,” went on Mrs. Van Reypen. “You have had very good training. I shall be glad to have you dance for me often. But—and please remember this—never when any one else is here. I wish you to dance for me only. If I have guests, or if my nephew is here, you are not to dance.”

This was almost too much for Patty’s gravity. For she well knew the old lady was foolishly alarmed lest her nephew should fall in love with a humble “companion,” and, knowing that the said nephew had gleefully watched the dance, it was difficult not to show her amusement.

But she only said, “I will remember, Mrs. Van Reypen.” She couldn’t tell of the intruder after his frantic appeal to her for silence, so she determined to ignore the episode.

“Now, you may do as you like until luncheon time,” said Mrs. Van Reypen, “for I shall go to my room and lie down for a rest. My maid will attend me, so I will bid you adieu until one o’clock. Wander round the house if you choose. You will find much to interest you.”

“Right you are!” thought Patty to herself. “I don’t believe I’d have to wander far to find a jolly comrade to interest me!” But she well knew if Mr. Philip Van Reypen was still in the house, and if she should encounter him and chat with him, it would greatly enrage the old lady.

“And,” thought Patty, “since I’ve made good with my dancing it’s a shame to spoil my record by talking to Sir Philip. But he is pleasant.”

Determined to do her duty, she went straight to her own room, though tempted to “wander round the house.”

And sure enough, though she didn’t know it, Mr. Van Reypen was watching her from behind the drawing-room draperies. His face fell as he saw her go up the stairs, and, though he waited some time, she did not return.
