At that moment Baron Cloten returned, his face beaming with delight.

"Miss Emily," he said, "your aunt wishes to speak to you. May I have the honor to take you to her?"

"Directly," said Emily, and then to Felix: "Rely on what I told you. You have sharp eyes and ears."

She took Cloten's arm.

"I must find that out," said Felix to himself when he was alone again. "Helen's manner has really been extraordinary of late."

He went up to the piano. "Shall I turn the music for you, Helen?"

"Thanks," Helen replied dryly. "I play from memory."

After a short pause: "Please, cousin, go away. It makes me nervous to have anybody stand so close behind me."

"It seems to me Doctor Stein stood yesterday half an hour behind you and you did not show any great nervousness."

"Then I will rise," said Helen. She wound up with a short finale and left the piano, without paying any attention to the general Ah! of the dancers.
