“Then she smiled and it was terrible. Madeline’s lips pulled up at the corners in a terrible parody of good humor, her mouth stretching painfully wide, her jaw dropped so far that it looked almost like a scream. Above that awful grin, her eyes were as flat and dead as stones. I do not delude myself that I have seen every way the human mind can fail, though I have seen a hundred ways that soldiers and civilians can break in war. But I had never seen a smile like that.”
