Death continued to stare at the emperor with his cold, hollow eyes, and the room was fearfully still. Suddenly there came through the open window the sound of sweet music. Outside, on the bough of a tree, sat the living nightingale. She had heard of the emperor's illness, and was therefore come to sing to him of hope and trust. And as she sung, the shadows grew paler and paler; the blood in the emperor's veins flowed more rapidly, and gave life to his weak limbs; and even Death himself listened, and said, "Go on, little nightingale, go on."
