"Oh, Lord Lancaster, you are too late! She is come now!" cried Lady Adela, for her glance, too, had fallen on the graceful, hesitating figure. She saw with inexpressible chagrin that Leonora was in simple but faultless costume. Her dress, of some soft, shining, thin, black material, was of stylish and fashionable make, and her white shoulders and arms gleamed marble-white through the thin folds. She had arranged all her rich tresses of chestnut hair in loose puffs and waves on the top of her head, and fastened a single spray of starry white jasmine flowers at the side. Some of the same sweet, fragrant blossoms fastened the full ruff of white crÊpe lisse at the round, white throat, and constituted her only adorning. Her white arms and dimpled wrist, left bare by the elbow-sleeves of her dress, were more beautiful in their shapely grace than Lady Adela's ten-button gloves and diamond bracelets.

"She has had the impertinence to get herself up in full evening dress, the minx!" the earl's daughter muttered, almost audibly; and then she uttered a suppressed exclamation of annoyance, for Lord Lancaster had started for her side, and was making his way rapidly across the room to the door.

"He has left me for her!" was her jealous, angry thought, and a sudden hatred for Leonora entered her heart.

Meanwhile, Lord Lancaster had reached the spot where the girl was standing, with a slightly heightened color on her face, but with that quiet air of self-possession she habitually wore. She was not at all overwhelmed by the honor Lady Lancaster had thrust upon her, but she was a little indignant at the dowager, who purposely left her standing there alone, taking care that De Vere did not see her and go to her rescue.

But she forgot her nephew sitting in full view across the room, or she thought that he would not forsake the side of Lady Adela. What was her amazement when she saw him standing by the girl's side, saw the fair face lifted to his with a grateful smile!

"Lady Lancaster has commanded your humble servant to appear before your highness and execute divers pieces of music," she was saying, mischievously, when the dowager pounced down upon them like a hawk, and, with an angry aside to her nephew, bore Leonora off to the piano.

The next minute De Vere came forward gladly. By this time every one was looking, yet he was in nowise intimidated.

"Oh, Miss West, how glad I am to meet you, and looking as charming as ever, too!" in an audible aside, while his face beamed with delight. Leonora drew her hand rather hastily away.

"I am not here on equal terms, please remember that," she said, turning around and sitting down on the piano-stool. "It is my lady's orders that I shall amuse the company."

"Then I shall turn your music—may I?" he entreated.

She gave a careless assent, and looked at the great pile of music.

"Perhaps you will select something to play," she said; and seeing, without turning her head, that Lancaster had gone back to his seat by the earl's daughter.

"He is afraid she will be jealous of me," the girl said to herself, with the least little curl of her red lip.

"Can you play this?" De Vere inquired, placing a simple little song before her.

"Yes; but I do not want a song, please. Give me something by Mozart or Rossini—something brilliant. I am on exhibition, you see," saucily.

"Can you really play Mozart?" he whispered to her as he searched for the music.

"Oh, yes; and Beethoven, too. I am fond of music, so I have studied it a great deal. I can play almost anything," she said, carelessly, as she took the piece he handed her—an exceedingly brilliant and difficult piece by Mozart, and ran her quick eyes over it.

She placed the music before her, and struck the first notes. The hum of voices in the room grew instantly still. No one spoke while that grand torrent of music rose and fell on the charmed air, as those slim white fingers of Leonora swept the echoing keys. They forgot the performer for a little, even as she forgot them. Her cheeks glowed, her eyes sparkled. While she played she remembered nothing but the harmonies that were shed from her subtle finger-touches. The art of the grand composer charmed her, and when she paused at last, it was with a low sigh of blended pain and pleasure.

"Brava!" said De Vere, bending over her, and she smiled.

"Have I done well? It is because I have a passion for music, and have given my soul to it."
