For a long time she lay back, drinking, in long draughts, the spiced night air, frosted only enough to give it flavor. There was no necessity for speech, and above, the stars glittered lavishly, despite the white light of the moon.

At last she murmured half-aloud and almost contentedly: "'Who knows but the world may end to-night?'"

Above the throbbing purr of the engine which had already done ten miles, the man beside her caught the voice, but missed the words. He bent forward.

"I beg your pardon?" he politely inquired.

At the question she started violently, and both hands came to her heart with a spasmodic movement. Von Ritz carried the car around an ugly rut.

"Don't be alarmed, Your Highness," he said, in a cold, evenly modulated voice which, though pitched low, carried clearly above the noise of the cylinders. "I may call you 'Your Highness' now, may I not? We are quite alone. Or do you still prefer that I respect your incognita?"

The girl's eyes blazed upon him until he could feel their intense focusing, though he kept his own fixed unbendingly on the road ahead. Finally she mastered her anger enough to speak.

"Colonel Von Ritz," she commanded, "you will take me back at once!" She drew herself as far away from him as the space on the seat permitted.

"Your Highness's commands are supreme." The man spoke in the same even voice. "I intend taking Your Highness back—when it is safer for Your Highness to go back."

He turned the car suddenly to the right and sped along the narrower road that led away from the main thoroughfare.
