But not knowing who Psyche was, they shook their heads.

"And that is not all," continued Ilse. "A Prussian prince was here, a fine and gallant man, tall and young. He, too, is at the feet of the lovely Mademoiselle Julie. I heard him say that he had seen her before she was brought to Zillenstein."

John's pulses suddenly beat hard. He knew instinctively the identity of the Prussian prince, but he asked quietly:

"What was the man from Prussia called?"

"Prince Wilhelm von Arnheim. I was present when he first saw here the beautiful Mademoiselle Julie. He bent before her and kissed her hand, as if she were a princess herself. The look that he gave her was full of love, and it was also most respectful. I, Ilse Brandt, know."

"I've no doubt of it, because you've received many such looks yourself, beautiful Ilse," said John.

"There she is now! At the window!" exclaimed Olga.

John looked at once, and his heart leaped within him. Julie stood framed in a window, high up in the new part of the castle. The light seemed to fall upon her, as one turns it in a flood upon a picture, and her figure was in the center of a glow that brought out the coppery touches in the wonderful golden hair, that was the marvel of everybody. She seemed to be gazing wistfully over the misty mountains, and John's heart was full of yearning.

"I can't believe," said Ilse, "that she is a spy or has ever been a spy. She has not the look, nor the manner. When the Prince von Arnheim was here they gave a great dinner, and Prince Karl bade her come to it. I took her a beautiful dress of his niece, who is away in Vienna. I thought she would refuse, but she said that she would come as Prince Karl requested. I was her maid, I dressed her and she was very beautiful. She went to the dinner, and the aged Lady Ursula, the cousin and dependent of the prince, sat with her."

"What happened?" asked John in a low voice.
