Katherine hesitated.

"I've got a confession to make," she said at last.

Maggie turned to look at her with her large childish eyes.

"Oh, I do hope you've done something wrong," she said, laughing, "something really bad that I should have to 'overlook.'"

"What do you mean?" asked Katherine.

Maggie only said: "We'd be more on a level then."

"I don't think it's anything very bad. But the truth is, Maggie, that I didn't ask you here only for my own pleasure and to make you well. There was a third reason."

"I know," said Maggie; "Paul."

"My dear!" said Katherine, amazed. "How did you guess? I never should have done."

"Paul's asked you to find out whether I like him," said Maggie.
