Helen's sense seemed to have much in common with the ruthless good sense of nature, which avenged rashness by a headache, and, like nature's good sense, might be depended upon.
Rachel went to bed; she lay in the dark, it seemed to her, for a very long time, but at length, waking from a transparent kind of sleep, she saw the windows white in front of her, and recollected that some time before she had gone to bed with a headache, and that Helen had said it would be gone when she woke.

She supposed, therefore, that she was now quite well again.

At the same time the wall of her room was painfully white, and curved slightly, instead of being straight and flat.

Turning her eyes to the window, she was not reassured by what she saw there.
