The Princess and Curdie by George MacDonald

He found himself in a large room, dimly lighted by a silver lamp that hung from the ceiling. Far at the other end was a great bed, surrounded with dark heavy curtains. He went softly toward it, his heart beating fast. It was a dreadful thing to be alone in the king's chamber at the dead of night. To gain courage he had to remind himself of the beautiful princess who had sent him.

But when he was about halfway to the bed, a figure appeared from the farther side of it, and came towards him, with a hand raised warningly. He stood still. The light was dim, and he could distinguish little more than the outline of a young girl. But though the form he saw was much taller than the princess he remembered, he never doubted it was she. For one thing, he knew that most girls would have been frightened to see him there in the dead of the night, but like a true princess, and the princess he used to know, she walked straight on to meet him. As she came she lowered the hand she had lifted, and laid the forefinger of it upon her lips. Nearer and nearer, quite near, close up to him she came, then stopped, and stood a moment looking at him.
