The drive to the ruins had been a great success. It was a drive of just sufficient length to put people in spirits without fatiguing them. The party came back to lunch with delightful appetities. Lady Agatha and Miss Cora Brooke had pink cheeks. The Marquis of Walderhurst had behaved charmingly to both of them. He had helped each of them to climb about among the ruins, and had taken them both up the steep, dark stairway of one of the towers, and stood with them looking over the turrets into the courtyard and the moat. He knew the history of the castle and could point out the banquet-hall and the chapel and the serving-places, and knew legends about the dungeons.
"He gives us all a turn, mother," said Miss Cora Brooke. "He even gave a turn yesterday to poor Emily Fox-Seton. He's rather nice."
There was a great deal of laughter at lunch after their return. Miss Cora Brooke was quite brilliant in her gay little sallies. But though she was more talkative than Lady Agatha, she did not look more brilliant.
The letter from Curzon Street had not made the beauty shed tears. Her face had fallen when it had been handed to her on her return, and she had taken it upstairs to her room with rather a flagging step. But when she came down to lunch she walked with the movement of a nymph. Her lovely little face wore a sort of tremulous radiance. She laughed like a child at every amusing thing that was said. She might have been ten years old instead of twenty-two, her colour, her eyes, her spirits seemed of a freshness so infantine.
She was leaning back in her chair laughing enchantingly at one of Miss Brooke's sparkling remarks when Lord Walderhurst, who sat next to her, said suddenly, glancing round the table:
"But where is Miss Fox-Seton?"
It was perhaps a significant fact that up to this moment nobody had observed her absence. It was Lady Maria who replied.
