"I can't imagine what you will do."

"I don't quite know myself yet, but I am not sister to four brothers for nothing. If you only could guess, Molly, what scrapes those boys have been in—the kind of things even Maurice has been suspected of doing. But I have always got them to confide in me; and somehow, when we talked the thing out, and straightened it a bit, and got the tangles out of it, as it were, we always began to get glimpses of daylight. Of course I could not interfere in the boys' affairs as I can in yours, but I have before now set quite hopeless sort of scrapes—indeed they seemed so at the time—straight."

"Well, I wish you would take me up," said Molly.

"I intend to, you may be sure, and also that poor Kate O'Connor. Of course I am angry with her for suspecting you, but it is impossible not to love her and be interested in her. Now, Molly, I want you to promise me one thing."

"What is that?"

"Just tell Kate the truth quite simply to-morrow; don't exaggerate, and don't protest. Tell her you know she suspects you, assure her of your innocence, and then leave the matter in my hands; don't say another word. Of course it is easy to guess who is at the bottom of all the mischief."

"Who?" inquired Molly.

"Why, Matilda Matthews! Did you notice how anxious Kate was to keep her in the room this evening, and how often Matilda made for the door? I was quite amused watching the clever way in which Kate kept her victim within sight. Of course I could not guess her motive at the time; now I see that she wanted to shame Matilda thoroughly."

"Yes; I hate Matilda!" said Molly. "I never did hate anyone before, but I hate her! Of course she has made the mischief; but how did she find out? That is the puzzle of all puzzles, Cecil."

"Of course it is a puzzle," said Cecil; "but we'll drag it into the light of day somehow. Now, Molly, I'm dead tired, and I think I must say good-night."
