Curdie saw how it was, and begged her to allow him to lie on the floor, but she would not hear of it.
In the night he was waked by Lina pulling at him.

As soon as he spoke to her she ceased, and Curdie, listening, thought he heard someone trying to get in.

He rose, took his mattock, and went about the house, listening and watching; but although he heard noises now at one place now at another, he could not think what they meant for no one appeared.
Certainly, considering how she had frightened them all in the day, it was not likely any one would attack Lina at night.

By and by the noises ceased, and Curdie went back to his bed, and slept undisturbed.
In the morning, however, Derba came to him in great agitation, and said they had fastened up the door, so that she could not get out.

Curdie rose immediately and went with her: they found that not only the door, but every window in the house was so secured on the outside that it was impossible to open one of them without using great force.
