She went down-stairs to the piano and played with strong feeling. Presently she began to sing a haunting melancholy song by Abt. From Abt she turned to Flotow; from Offenbach to Rossini; from Gounod to Verdi. The voice was now sad or gay, now tender or wild. She was mistress of every tone, every shade, every expression.

The door opened gradually. The little maid's face was moved to rapture over these exquisite sounds.

Crash! It was over.

"Bettina? Bettina, are you listening?"

"I am always listening." Bettina squeezed into the room. "I had not the heart to interrupt. It is beautiful, beautiful! To sing like that!" Then, with a burst of confidence: "There will be kings and dukes at your feet!"

"Enough!"

"Pardon, signora, I forgot. But listen; I bring a message. A boy came to say that the rehearsal will be at four this afternoon. It is now after twelve."

"So late? I did not know. We must be off to lunch."

"And the letter up-stairs on the floor?"

"Some day, Bettina, you will enter the Forbidden Chamber, and I shall have to play Bluebeard. This time, however, I do not mind. Leave it there or burn it," indifferently.
