"You're launched now, lad—fair launched! And I know you'll float," said old Jack, grave at last, as he took his leave, his precious letter most carefully stowed away in his breast-pocket. It had been a great day for Jack, great for what he had done, great for the way in which his doing it had come about.

Within less than twenty-four hours Montreal had been written to, Gilly Foot had been written to—and Andy was at the Nun's door.

She dwelt with Miss Dutton in a big block of flats near Sloane Street, very high up. Her sitting-room was small and cosy, presenting, however, one marked peculiarity. On two of the walls the paper was red, on the other two green. Seeing Andy's eyes attracted by this phenomenon, the Nun explained: "We quarrelled over the colour to such an extent that at last I lost my temper, and, when Sally was away for a day, had it done like this—to spite her. Now she won't let me alter it, because it's a perpetual warning to me not to lose my temper. But it does look a little queer, doesn't it?"

She had received him with her usual composure. "I knew you'd come, because I knew Mr. Jack Rock would do as I wanted, and I was sure he couldn't keep the letter to himself. Well, that's all right! It was only that the obvious thing wanted doing."

"But I don't see—well, I don't see why you should care."

She looked at him, a lurking laugh in her eye.

"Oh, you needn't suppose that it was life and death to me! It was rather fun, just on its own account. You'll like Gilly; he's a good sort, though he's rather greedy. Did you notice that? Billy's really my friend. I'm very fond of Billy. Are you ambitious? Billy's very ambitious."

"No, I don't think I am."

The Nun lay back on a long chair; she was certainly wonderfully pretty as she smiled lazily at Andy.

"You look a size too large for the room," she remarked. "Yes, Billy's ambitious. He'd like to marry me, only he's ambitious. It doesn't make any difference to me, because I'm not in love with him; but I'm afraid it's an awfully uncomfortable state of affairs for poor Billy."
