'The name she passed under when I met her was Helen Vaughan, but what her real name was I can't say. I don't think she had a name. No, no, not in that sense. Only human beings have names, Villiers; I can't say any more. Good-bye; yes, I will not fail to call if I see any way in which you can help me. Good-night.' The man went out into the bitter night, and Villiers returned to his fireside. There was something about Herbert which shocked him inexpressibly; not his poor rags nor the marks which poverty had set upon his face, but rather an indefinite terror which hung about him like a mist. He had acknowledged that he himself was not devoid of blame; the woman, he had avowed, had corrupted him body and soul, and Villiers felt that this man, once his friend, had been an actor in scenes evil beyond the power of words. His story needed no confirmation: he himself was the embodied proof of it. Villiers mused curiously over the story he had heard, and wondered whether he had heard both the first and the last of it. 'No,' he thought, 'certainly not the last, probably only the beginning. A case like this is like a nest of Chinese boxes; you open one after another and find a quainter workmanship in every box. Most likely poor Herbert is merely one of the outside boxes; there are stranger ones to follow.' Villiers could not take his mind away from Herbert and his story, which seemed to grow wilder as the night wore on. The fire began to burn low, and the chilly air of the morning crept into the room; Villiers got up with a glance over his shoulder, and shivering slightly, went to bed. A few days later he saw at his club a gentleman of his acquaintance, named Austin, who was famous for his intimate knowledge of London life, both in its tenebrous and luminous phases. Villiers, still full of his encounter in Soho and its consequences, thought Austin might possibly be able to shed some light on Herbert's history, and so after some casual talk he suddenly put the question: 'Do you happen to know anything of a man named Herbert--Charles Herbert?' Austin turned round sharply and stared at Villiers with some astonishment. 'Charles Herbert? Weren't you in town three years ago? No; then you have not heard of the Paul Street case? It caused a good deal of sensation at the time.' 'What was the case?'
