You know whose fault it is—whose hands have robbed me,” he said fiercely; “whose lips have given to another what once they gave to me.”

“Never, never!” The words broke involuntarily from her lips, though what it was she denied so furiously was not quite clear at first.

“You will not deny that for a few moments at least, I had a right to believe that you gave them to me? You kissed me back that morning.”

She said no word at that, only put up her hand to her eyes for a moment as though to shut out something. The gesture brought into sight the yellow diamond, and with a finger he scornfully indicated it.

“Is not that a symbol of what I have lost—and another gained?”

Even as he spoke the large shadow bore down on them of Montague come to expostulate concerning a sit-out dance that was booked to him. Vivienne’s voice, low, but very clear and cold, cut short his plainings.

“This ring is merely the symbol of a business arrangement between myself and Mr Montague. He very kindly lent me a sum of money with which to make a good speculation. I went to him in preference to applying to a money-lender, and in honour of my confidence in him he asked me to wear this charming stone. When I return the money in three months’ time or less, I also return the ring. Is not that exactly how the matter stands, Mr Montague?”

“I believe it is,” responded Montague with exceeding dryness, and looking anything but amiable. The unexpectedness of the attack took the wind out of his sails. He would have had more pleasure in bomb-shelling de Windt than making any statement of the kind.

“That is all then, thank you,” said Vivienne calmly. “I shall have finished my talk with Mr de Windt in about five minutes’ time.”

Millionaires in South Africa are not accustomed to such treatment, and if Montague had been followed he might have been heard to mutter in his wrath that she could finish her conversation with de Windt in Hades if she liked. The principal fact, as far as Vivienne was concerned, was that he departed. De Windt too had risen, his haggard face grown very dark.
