It took some time to go over the attic, although if there were some connection between the attic and Jannet’s room, it could only be in a certain part, the girls thought, and there they spent some time. They looked dubiously at various piles of boards not far from the partition. Some old carpet close to it Jannet with great effort drew aside till she could see how the floor looked at the angle. The girls grew a little tired. What was the use of doing it all to-day? Jannet suspected the big cupboard that stood against the partition, but their combined strength could not move it, and there was no indication of a way through it and the partition.

“Let’s go down, have our supper, and give this up till to-morrow, Nell. We had too much fun dressing up first. Besides, we ought to have some one help us move the heavy stuff. I’ll ask Uncle Pieter.”

Nell, who was quite ready for something different, assented. Gradually they made their way back to the trunks, though they did pause again to examine anything that seemed worth while to know about. If their hands had been soiled before, they were “filthy” with the “dust of ages,” Nell declared,—“with all apologies to Paulina, Jannet.”

Again jingling her keys, Jannet went to the door, which she had closed before they began their search in the other part of the attic, though why Jannet scarcely knew. Surely there was no one to watch them. “Why!” Jannet exclaimed, “it doesn’t open!” She looked at Nell, startled. “Try it for yourself!” Nell shook the door and they looked at each other in dismay.

“Could Paulina have locked it by mistake?” asked Nell.

“Some one very likely has locked this on purpose,” declared Jannet presently. The two girls stood by the door, puzzled, slightly alarmed. “This is a mess, Nell. It doesn’t look as if I’d get you that good supper we were going to have.”

“Perhaps we can call to some one from the window.”

“Perhaps we can. But the tenant house is where all the evening activities are, unless some one has an errand here. Paulina said that she would be back about seven o’clock, unless she took a notion to go to prayer-meeting with her sister. They drive to the village church. Daphne doesn’t sleep here. No telling how soon the girls will come back,—but who locked us in, then?”

“Never mind, Jannet. We have cookies, the fudge and something to drink. Your guardian angel must have told you to bring those up. Do you suppose we’ll have to be up here after dark?”

Jannet shook her head regretfully. “You be sister Ann, Nell, and watch the window for any one that might come. Paulina is the most likely one before dark, and it does not get dark early, fortunately. I’m going to see if I can’t open the door. I will know enough to lock the door myself the next time I am up here, and leave my key in the lock on this side. That’s what she has done, you see, and I can’t get my key in. I left it on the ring with the rest, or—”
