But the blushing face would not be turned towards his own. Margaret's head was still averted.

"Don't ask me," she pleaded; "don't ask me. The day would come when you would regret your choice. I could not endure that. It would be too bitter. You have been very kind to me; and it would be a poor return for your kindness, if——"

"If you were to make me unutterably happy, eh, Margaret? I think it would be only a proper act of gratitude. Haven't I run all over Clapham, Brixton, and Wandsworth—to say nothing of an occasional incursion upon Putney—in order to procure you half-a-dozen pupils? And the very first favour I demand of you, which is only the gift of this clever little hand, you have the audacity to refuse me point-blank."

He waited for a few moments, in the hope that Margaret would say something; but her face was still averted, and the trembling hand which Mr. Austin was holding struggled to release itself from his grasp.

"Margaret," he said, very gravely, "perhaps I have been foolish and presumptuous in this business. In that case I fully deserve to be disappointed, however bitter the disappointment may be. If I have been wrong, Margaret; if I have been deceived by your sweet smile, your gentle words; for pity's sake tell me that it is so, and I will forgive you for having involuntarily deceived me, and will try to cure myself of my folly. But I will not leave this room, I will not abandon the dear hope that has brought me here to-night, until you tell me plainly that you do not love me. Speak, Margaret, and speak fearlessly."

But Margaret was still silent, only in the silence Clement Austin heard a low, sobbing sound.

"Margaret darling, you are crying. Ah! I know now that you love me, and I will not leave this room except as your plighted husband."

"Heaven help me!" murmured Joseph Wilmot's daughter; "Heaven lead me right! for I do love you, Clement, with all my heart."

CHAPTER XXVIII.
BUYING DIAMONDS.

Mr. Dunbar did not waste much time before he began the grand business which had brought him to London—that is to say, the purchase of such a collection of diamonds as compose a necklace second only to that which brought poor hoodwinked Cardinal de Rohan and the unlucky daughter of the Caesars into such a morass of trouble and slander.
