She was re-entering the carriage with a smile again upon her face, when the man who had acted as Beaton's valet came round from the back and stood beside her; at sight of him her smile vanished. He raised his hat to Beaton.

"I also am pleased to have met you." He turned to the woman. "I think, if you don't mind, or even if you do, that we'll keep that engagement together. After you into the carriage."

Evidently she found the sight of him by no means gratifying.

"What's the meaning of this? What are you doing here? I thought it was agreed that you should wait for me till I came back."

"I had a sort of idea that I might keep on waiting; it even struck me as just possible that you might never come back at all. After you into the carriage."

She hesitated; looked as if she would like to refuse; then, with a laugh, which was hardly a happy one, she did as he suggested. He followed her; the door was shut; the carriage drove off. Sydney Beaton was left standing on the pavement; oblivious of what was taking place, of where he was; as incapable, just then, of taking care of himself as any inmate of an asylum. He remained standing where they had left him, swaying to and fro. The fog had thickened; a drizzling rain had begun to fall. It was not easy to make out where he was, but he was at the corner of a street, in what seemed to be an old-world square, which in that moment was as deserted as if all the houses round about it had been empty and it was miles away from anywhere.

But presently his solitude was broken; two men came round the corner, doubtful-looking men, shabby-genteel looking men, in some queer way the sort of men one would expect to find prowling about in such a place at such a time. At sight of Beaton they paused; they exchanged glances; one nudged the other. Then one spoke to him, with what he possibly meant to be an ingratiating smile.

"Nasty day, captain; looks as if we were going to have a real London particular." When Sydney seemed to be unconscious even of his presence his tone became a little insolent. "Waiting for anybody, guv'nor--or are you just a-taking of the air?"

The other spoke, with a glance at his companion which had in it something which was evil:

"Can't you see that the gentleman's taking of the air? What he wants is someone to take it with him; what do you say to our offering the gentleman our society?"
