"And will you not tell me how you discovered the truth?" she asked.

"I chanced to learn of this meeting with His Royal Highness, the Duke of Lotzen, and was a witness of all that occurred here between you."

"You cannot mean that you overheard our conversation!" she exclaimed.

"Every word," said the King.

"But where—and how?"

The Duke glanced up toward the Gallery—and a bitter smile crossed his face.

"His Grace of Lotzen has guessed it," said Frederick.

She turned to the Duke interrogatingly.

"The gallery—behind the arras, yonder," he said.

"Exactly," said the King.
