They paused by common consent where the Heath drops suddenly from the edge of the road; opening out the view towards London. The hollow beneath them, filled by a thin fog, had become mysterious and immense.

"By the way," said Maddox, following an apparently irrelevant train of thought, "what has become of your friendship for Miss Poppy Grace?"

"It has gone," said Rickman, "where the old trousers go. Look there—"

Above them heaven seemed to hang low, bringing its stars nearer. A few clouds drifted across it, drenched in the blue of the night behind them, a grey-blue, watery and opaque. Below, sunk in a night greyer and deeper, were the lights of London. The ridge they stood on was like the rampart of another world hung between the stars which are the lights of poets, and the lights which are the stars of men. Under the stars Maddox chanted softly the last verses of the Song of Confession that Rickman had made.

"Oh, Ricky-ticky," he said, "you know everything. How did you know it?"

"Because I've been there."

"But—you didn't stay?"

"No—no. I didn't stay. I couldn't."

"I'm still there. And for the life of me I see no way out. It's like going round in the underground railway—a vicious circle. Since you're given to confession—own up. Don't you ever want to get back there?"

"Not yet. My way won't take me back if I only stick to it."
