But Isobel had gone. He looked for a moment at the door of her room through which she had vanished, and then he turned on his heel and followed me. He threw his hat upon the table and faced us both defiantly.

"It is I," he said, "who have something to say to you, and I'd like to get it over quick. D—n your hypocritical compact, Arnold Greatson! There! You're in love with Isobel! Any fool can see it, and you want to keep the child all to yourself."

Allan took a quick step forward, but I held out my hand.

"Don't interfere, Allan," I said. "Let him say all that he has to say."

"I mean to!" Arthur continued, "and I hope you'll like it. The compact was a fraud from beginning to end, and I'll have no more to do with it. Isobel's too old to live here with you fellows, and I'm going to ask her to marry me. I'm going to advise her to go and stay with Lady Delahaye, who wants her, and I'm going to marry her from there if she'll have me."

"Lady Delahaye," I repeated thoughtfully. "You have been in communication with her, have you?"

"Yes, I have! And I think she's right. Isobel ought to have some women friends. She may have enemies, but I'm not so sure about that. Lady Delahaye isn't one of them, at any rate. The people who want to get her away from here may be her best friends, after all."

"Is that all, Arthur?"

"It's enough, isn't it?" he answered doggedly.

"Quite! Now listen," I said. "To-night we are going to hear Isobel's history. We are going to know who she is, and all about her. Stay with us, and you shall share the knowledge. As for the rest, you have been talking like a fool. We do not wish to take you seriously. We took up the charge of Isobel jointly. If the time has come now for us to give her up, I should like us all to be in agreement. It is very likely that the time has come. I, too, think that in many ways it would be for her benefit. We are prepared to give her up when we know the proper people to undertake the care of her—but never, Arthur, to Lady Delahaye."
