"Pietro, she is more than beautiful!" sighed O'Mally.

"But wait," said Pietro. He alone among the men knew the cause of Worth's disappearance. "Trouble."

Leaning against the door which gave entrance to the ball-room from the hall were two officers, negligently interested in the moving picture. "What do you make of it?" asked one.

"Body of Bacchus, you have me there!"

"Shall we go?"

"No, no! The prince himself will be here at eleven. He was, singularly enough, not invited; and knowing the story as I do, I am curious to witness the scene. The women are already picking her to pieces. To give a ball in this hurried manner, without ladies in attendance! These Americans! But she is beautiful," with evident reluctance.

Hillard, peering gloomily over their shoulders, overheard. The prince! Oh, this must not be. There could be only one prince in a matter of this kind. He pushed by the Italians without apology for his rudeness, edged around the ball-room till he reached La Signorina's side. He must save her at all hazards.

"A word," he whispered in German.

"What is it?" she asked in the same tongue.

"The prince himself will be here at eleven."
