"The Griffin's" surprise at seeing them seemed as great as their own. She gave a gasp of consternation, peeped hastily inside the empty room, then turned to Lindsay and Cicely with a look of mingled relief and wrath.

"What were you doing in the lantern room?" she asked sharply. "You know perfectly well you've no right to be up here. You must mind your own business, and keep to your own places, instead of poking and ferreting about into matters that don't concern you. I can't have you rambling about wherever you please, and the sooner you understand that the better. It was sorely against my advice that the Manor was let for a school!"

She spoke rudely, and seemed more upset and annoyed than the occasion warranted. She swept the two girls downstairs before her, muttering angrily as she went, and did not let them out of her sight until she had watched them safely into the garden.

"How horrid she was!" exclaimed Cicely, when they were alone, and able to talk things over. "Miss Russell never said we weren't to go on to that top landing."

"What was Mrs. Wilson doing there herself—in an empty room, in such a deserted part of the house?" asked Lindsay meditatively.

"I don't know. She looked quite aghast at seeing us."

"I believe there's something about it we don't understand. Perhaps she has some reason beyond mere fussiness and nastiness for wanting to keep us away from that particular room."

"What kind of a reason?"

"Well, suppose she had discovered the hiding-place?"

"Wouldn't she tell Monica?"
