"I do," said Lady Randolph, with a smile.

She was mollified, for her French was excellent, and she liked a little compliment, of whatever kind.

"You should give your mind to it; it is the most useful of all languages," she said.

"And Lucy is not great at it either," said Jock.

"That is true, and it is a pity," said Lady Randolph, quite restored to good-humour. "I would take her in hand myself, but I have so many things to do. Do you know where she is, for I have not seen her all this morning?"

"No more have I," said Jock. "I think they have just gone off somewhere together. Lucy never minds. She ought to pay a little attention when there are people in the house."

"That is just what I have been thinking," Lady Randolph said. "I am at home, of course, here; it does not matter for me, and you are her brother—but she really ought; I think I must speak seriously to her."

"To whom are you going to speak seriously? I hope not to me, my dear aunt," said Sir Tom, coming in. He did not look quite his usual self. He was a little pale, and he had an air about him as of some disagreeable surprise. He had the post-bag in his hand—for there was a post twice a day—and opened it as he spoke. Lady Randolph, with her quick perception, saw at once that something had happened, and jumped at the idea of a first quarrel. It was generally the butler Williams who opened the letter-bag; but he was out of the way, and Sir Tom had taken the office on himself. He took out the contents with a little impatience, throwing across to her her share of the correspondence. "Hallo," he said. "Here is a letter for Lucy from your tutor, Jock. What have you been doing, my young man?"

"Oh, I know what it's about," Jock said in a tone of satisfaction. Sir Tom turned round and looked at him with the letter in his hand, as if he would have liked to throw it at his head.
