That's the name I'd forgotten!
Wikipedia hosts extracts from William Stead's articles and it can be clearly seen that the manipulations of human traffickers have changed very little. This is the technique sometimes nicknamed the "loverboy method", clearly described over a hundred years ago.
Stead quoted a former brothel-keeper who confirmed the nature of the trade*
"Maids, as you call them – fresh girls as we know them in the trade – are constantly in request, and a keeper who knows his business has his eyes open in all directions, his stock of girls is constantly getting used up, and needs replenishing, and he has to be on the alert for likely "marks" to keep up the reputation of his house. I have been in my time a good deal about the country on these errands. The getting of fresh girls takes time, but it is simple and easy enough when, once you are in it. I have gone and courted girls in the country under all kinds of disguises, occasionally assuming the dress of a parson, and made them believe that I intended to marry them, and so got them in my power to please a good customer. How is it done? Why, after courting my girl for a time, I propose to bring her to London to see the sights. I bring her up, take her here and there, giving her plenty to eat and drink–especially drink. I take her to the theatre, and then I contrive it so that she loses her last train. By this time she is very tired, a little dazed with the drink and excitement, and very frightened at being left in town with no friends..."
"I offer her nice lodgings for the night: she goes to bed in my house, and then the affair is managed. My client gets his maid, I get my £10 or £20 commission, and in the morning the girl, who has lost her character, and dare not go home, in all probability will do as the others do, and become one of my "marks"–that is, she will make her living in the streets, to the advantage of my house. The brothel keeper's profit is, first, the commission down for the price of a maid, and secondly, the continuous profit of the addition of a newly seduced, attractive girl to his establishment. That is a fair sample case of the way in which we recruit.
