"Here we are, in thick boots and country clothes capering about like savages round their fire, and, for all sorts of reasons, we all love it!" "It is just the delicious exercise with me," said Lady Ethelrida.
"And it has nothing at all to do with that reason with me," returned her partner.

They were the same height, and he saw her look; and as they went on, he whispered: "I have brought you down the book we spoke of, you know, and you will take it from me, won't you?
Just as a remembrance of this day and how you made me young for an hour!" They stopped by one of the benches at the side and sat down, and Lady Ethelrida answered softly, "Yes, if--you wish me to--" Lord Elterton had now dislodged Young Billy and was waltzing with Zara himself: his whole bearing was one of intense devotion, and she was actually laughing and looking up in his face, still affected by the general hilarity, when the door of the wooden porch that had been built on as an entrance opened noiselessly, and some of the shooters peeped into the room.

It had been too impossibly wet to go on, and they had sent the ladies back in the motors and had come across the park on their way home, and, hearing the sound of music, had glanced in.

Tristram was in front of the intruders and just chanced to catch his bride's look at her partner, before either of them saw they were observed.
He felt frightfully jealous.

He had never before seen her so smiling, to begin with, and never at all at himself.
