"But really, Miss Murray——" he began, as he rose, not a little bewildered, from his chair.

"Stop!" she said. "In mercy to yourself and your wife, stop! There is the door; go, and remember that from now we are strangers, and if ever you meet Carol again—no, I won't say that. God grant that you never may see her again, for if you do——"

"Well, and suppose I do, Miss Murray, what then?" he interrupted, with his hand on the handle of the door. He had never heard such words from the lips of either man or woman before, and that personal vanity which is a characteristic even of the worst of men was grievously outraged.

"Never mind what I mean," she said, cutting him short again. "I have said all that I am going to say except this—if ever you meet Carol again, for her sake and yours, for your wife's and your children's when they come, don't see her. Now go!"

There was a something in her voice and in her manner which said even more than her lips had done. Something which not only struck him dumb for the time being, but which also drove home into his soul a conviction that this girl, outcast and social pariah as she was, not only held his fate in her hands, but that she possessed some unknown power over his destiny, that she knew something which, if spoken, might blast the bright promise of his life and overwhelm him in irretrievable ruin.

She had called him a cad, and as his thoughts flew back to that morning in Vane Maxwell's rooms at Oxford, a pang of self-conviction told him that she had spoken justly. He felt, too, that he was hopelessly in the wrong, that by his suggestion he had sorely insulted her, and that in exchange for his insult she had given him mercy. He would have given anything to know the real meaning of her words, and yet he dare not even ask her.

He looked round at her once and saw her, standing rigid and impassive waiting to be relieved of his presence. His thoughts went back a few months to the times when those little dinners of four had been so pleasant, and when this girl, who was now looking at him like an accusing angel, had matched even Carol herself in the gaiety of her conversation and the careless use she made of her mother-wit, and he tried hard to say something which should in some way cover his retreat, but the words wouldn't come, and so he just opened the door and walked out.

Dora heard the street door bang behind him, and then her tensely-strung nerves relaxed. She dropped into an easy chair, clasped her hands over her temples, and whispered:

"Oh dear, oh dear, how is all this going to end, and what would happen if they only knew! And now I've got to see Sir Arthur. Shall I tell him everything or not? No, I daren't, I daren't. It's too awful. Was there ever anything like it in the world before?"

And then her body swayed forward, her elbows dropped on to her knees, her hands clasped her temples tighter, and the next moment she had burst into a passion of tears.
