The Day Boy and the Night Girl by George MacDonald
t had not been there before the darkness came, she suspected that it had to do with the lamp. She kneeled therefore, and searched with her hands, and bringing two large pieces together, recognized the shape of the lamp. Therefore it flashed upon her that the lamp was dead, that this brokenness was the death of which she had read without understanding, that the darkness had killed the lamp. What then could Falca have meant when she spoke of the lamp going out? There was the lamp -- dead indeed, and so changed that she would never have taken it for a lamp, but for the shape! No, it was not the lamp anymore now it was dead, for all that made it a lamp was gone, namely, the bright shining of it. Then it must be the shine, the light, that had gone out! That must be what Falca meant -- and it must be somewhere in the other place in the wall. She started afresh after it, and groped her way to the curtain.
