He was in a strange mood. There came first the quick certainty that this was Margaret. And then, like a flood, this sense of her and of her nearness swept over him. She walked before him; but if she had been in his arms, as she once had been, he could not have felt her more near. If he looked, he would see her very thoughts. He told himself that all he had ever seen was a mirage-the real Margaret had never shared a single thought with him.

He had been quite sure that it was going to be immensely interesting to meet her again; it had not entered his head that he would be angry. Yet he had not walked half a dozen yards behind her before he was as angry as he had ever been in his life. He was angry in a new way-angry with Margaret for earning her living, angrier because she had mixed herself up in who knew what ridiculous and criminal conspiracy, and angriest of all because she had made him angry. Mixed with his anger-curiosity. What was at the bottom of it? What did it all mean? The explorer in him was most keenly on the alert. He meant to get to the bottom of the business.

Perhaps his step quickened a little; he was nearer her than he had meant to be when they passed under a street lamp. The light hung above it like a faint white cloud. _ He said, “How d’you do, Margaret?” and said it lightly and pleasantly. To Margaret Langton the voice came out of the fog and out of the past. There was a step that kept pace with her own. And then Charles Moray said her name- Charles. She turned, a ghost in a nimbus. The quick movement was Margaret, the rest a blur.

“Charles!”

Her voice was unbelievably familiar; it might have been some voice of his own speaking to him. It shook him, and a hotter anger than before leapt in him.

“Charles! How dare you frighten me like that!”

“Did I frighten you!” He spoke smoothly and easily.

Margaret caught her breath.

“I thought someone was following me. It’s horrible to be followed in a fog.”

“I was waiting for you, and I nearly missed you. That ass Archie had forgotten your address, so I had to try and catch you here.”

They walked on; the lamp receded. Margaret said,

“Why did you want to-catch me?”

He shrugged his shoulders.

“I’ve been away. Perhaps you haven’t noticed. One comes back, one sees one’s friend-”

“Friends-are we friends? I shouldn’t have thought you would ever want to see me again.”

This was the old Margaret, fiercely untactful. Charles leapt at the opening. He wanted to hit hard, to hurt her as much as possible. He kept his indifferent tone very successfully.

“Why on earth shouldn’t I want to see you? After all, we were friends for about ten years before we ever thought of getting engaged. Wasn’t it ten years? We were friends for ten years, and then we were engaged for six months, and then-we stopped being engaged. Well, the engagement being only an episode, it can be just wiped out. You see?”

No woman likes to be told that she was only an episode. Charles was pleasantly aware of this; aware too that he had succeeded in piercing some armour of defense.

She said, with a hot resentment, in her voice,

“How can we be friends? How can you possibly want to be friends with me?”

Charles laughed.

“My dear girl, why not? Do let us be modern. These things don’t last, you know. Do you expect me to be tragic after four years? I was naturally a bit peeved at the time. But one doesn’t go on being peeved.” He paused, then struck again and struck hard. “I’ve been looking forward immensely to seeing you-but of course I thought you would be married.”

“Married! I!”

“Well,” said Charles, “I didn’t suppose you turned me down just for the fun of the thing. Naturally there was someone else.”

Margaret turned on him, her head up.

“Did you say that just to hurt? Or did you believe it?”

Charles laughed again.

“A bit of both. I believed it all right.”

She made a sound-not a sigh or a sob, but a quick angry breath.

“Look here,” said Charles, “I’ll put nearly all my cards on the table if you like. I propose that we should wash out the episode and revert to the status quo ante. If you won’t do this, I shall naturally conclude that you mind meeting me, that you find it embarrassing or painful.”

Margaret was certainly very angry.

“My dear Charles, doesn’t it occur to you that I might simply be bored?”

“No, it doesn’t. We could fight like fiends, and we could hate each other like poison; but we could never be bored. When can I come and see you?”

“You can’t come and see me.”

“Too embarrassing? Too painful?”

There was no answer. He thought he heard her catch her breath again. He continued in a pleasant social manner:

“I was proposing, you know, to revert to the days before the episode. You were ten, weren’t you, when your people came to George Street? I seem to remember that you didn’t mince your words in those days. Why bother to mince them now? Why not revert-say anything you like?”

Margaret said nothing; she walked without turning her head. Charles walked beside her. He was sorry there was a fog; he would have liked to see her face. He gave her a moment; then he spoke again.

“No words bad enough?”

There were no words at all.

“When can I come and see you?”

Silence-the fog-a black slippery crossing- Basil Street. They crossed, and passed through another patch of hazy light.

“You used not to sulk,” said Charles meditatively.

She flung round on him then like an angry school-girl.

“How dare you?”

Charles was immensely pleased.

“Touché!” he said to himself; and then aloud, “I’m sorry-I haven’t any manners. I’ve been deprived of the refining influence of woman for four years, you see. When can I come and see you?”

They had reached the Knightsbridge pavement, and he stopped instinctively on its dark brink. It was very dark, the lights of the crawling cars only just discernible, the noise of the traffic a bewildering dull sound that seemed to come from everywhere at once.

Charles stopped, but Margaret Langton never hesitated; she walked straight on, and even as he looked round her she was lost in the shuffling, whispering, hooting gloom. Charles plunged after her. Someone swore, a hoarse voice shouted. “Where are you gettin’ to?” The hooter of a car went off right in his ear, and his shoulder collided violently with somebody’s driving-mirror. The next half minute continued to be like that, only more so.

He fetched up on the island in the middle of the road with feelings of relief. The island was crowded. Under the powerful light it was possible to see one’s next door neighbour. Charles annoyed all the rest of the people on the island by being neighbour to each of them in turn. He trod on several toes, was prodded in the ribs by a very powerful umbrella, and a number of people asked him what he thought he was doing. As it was impossible to explain that he was looking for Margaret, he had to say he was sorry a good many times.

Margaret was not on the island. He came to a standstill behind abroad blue serge back. A heavily built man stood just in front of him. He wore a rough blue coat of the pea-jacket style and had about this neck a large khaki muffler-the sort of thing that one’s aunts knitted stacks of during the war. The thought passed through Charles’ mind and then pricked him so sharply that he very nearly cried out. He had made the same comparison before, within the last few days; and he had made it about the same muffler. He had stared at that blue serge back and that khaki comforter before. He had stared through the knot-hole of his mother’s cupboard and seen that lumpy shoulder and that bullet head come into view as Number Forty, the deaf janitor, opened the door to Grey Mask’s visitors.

He pushed against the man, hoping to see his face; and as he did so, he said mechanically,
