"You know, your majesty, that I have inherited the habit of speaking aloud to myself from my father," replied the prince, with a constrained smile.

"The king my husband did not cease speaking when I made his appearance," exclaimed the queen, angrily; "he had no secrets to hide from me."

"The thoughts of my royal father were grand, and worthy of the sympathy of Queen Sophia Dorothea," said the prince, bowing low.

"God forbid that the thoughts of his son should be of another and less worthy character!" exclaimed the queen. "My sons should, at least, be too proud to soil their lips with an untruth; and if they have the courage to do wrong, they should also find courage to acknowledge it."

"I do not understand you, my dear mother;" and meeting her penetrating glance with quiet composure, he continued, "I am conscious of no wrong, and consequently have none to acknowledge."

"This is an assurance which deserves to be unmasked," exclaimed the queen, who could no longer suppress her anger. "You must know, prince, that I am not to be deceived by your seeming candor and youthful arrogance. I know that you were not alone, for I myself saw the lady coming here who kept you company while awaiting me, and I followed her to this house."

"Then it seems that your majesty has followed a fata morgana," said the prince, with a forced smile; "for, as you see, I am alone, and no one else is present in the conservatory."

But even while speaking, the prince glanced involuntarily toward the grotto which concealed his secret.

The Queen Sophia Dorothea caught this glance, and divined its meaning.

"There is no one in the saloon, and it now remains to examine the grotto," said she, stepping forward hastily.
