But nothing could be said or done to hinder Oliver from taking his place at the piano, for Lesley did not openly object, and her father could not interfere between her and his own guest. So Lesley sang, and did not sing so well as usual, for her heart failed her a little, partly through vexation and partly through disappointment at Maurice Kenyon's disappearance, but she gave pleasure to her hearers, in spite of what seemed to herself a comparative failure, and when she had finished her song, she was besieged by requests that she would sing once more.

"Sing 'Thine is my heart,'" Oliver's soft voice murmured in her ear.

"I have not that song here," said Lesley, quietly. She was not very much discomposed now, but she did not want to encourage his attention. She rose from the music-stool. "My music is downstairs," she said. "I must go and fetch it—I have a new song that Ethel has promised to play for me."

Oliver bit his lips and stood back as Lesley escaped by the door of the front drawing-room. Mr. Brooke's eye was upon him, and he could not therefore follow her; but he made his way into the library through the folding doors, and there a new mode of attack became visible to him. By the library door he gained the landing; and then he softly descended the stairs, which were now almost deserted, for the guests had crowded into the drawing-room, first to hear Lesley's song and then to listen to a recitation by Ethel Kenyon. But where had Lesley gone?

A subtle instinct told him that she had hidden herself for a moment—and told him also where to find her. The lights were burning low in her father's study, which had been set to rights a little, in order to serve as a room where people could lounge and talk if they wanted to escape the din of conversation in the larger rooms. He looked in, and at first thought it empty. But the movement of a curtain revealed some one's presence; and as his eyes became accustomed to the dimmer light, he saw that it was Lesley. She was standing between the fireplace and curtained window, and her hand was on the mantelpiece.

She started when she saw him in the doorway. It was her start that betrayed her. He came forward and shut the door behind him—Lesley fancied that she heard the click of the key in the lock. She tried to carry matters with a high hand.

"I am afraid I cannot find my music here," she said, "so please do not shut the door, Mr. Trent. There is little enough light as it is."

She walked forward, but he had planted himself squarely between her and the door. She could not pass.

"Mr. Trent——" she began.

"Wait! don't speak," he said, in a voice so hoarse and stifled that she could hardly recognize it as his own. "I must have a word with you—forgive me—I won't detain you long——"
