Chauvelin nodded. He was beginning to understand.

"Well, now, tell me," he said, with that bland patience which had so oft served him in good stead in his unavowable profession. "Tell me. Last year citizen Marat adopted—we'll say adopted—a child, whom he placed in the Leridans' house on the Pantin road. Is that correct?"

"That is just how it is, citizen. And I—"

"One moment," he broke in somewhat more sternly, as the woman's garrulity was getting on his nerves. "As you say, I know the Leridans' house. I have had cause to send children there myself. Children of aristos or of fat bourgeois, whom it was our duty to turn into good citizens. They are not pampered there, I imagine," he went on drily; "and if citizen Marat sent his—er—adopted son there, it was not with a view to having him brought up as an aristo, what?"

"The child was not to be brought up at all," the woman said gruffly. "I have often heard citizen Marat say that he hoped the brat would prove a thief when he grew up, and would take to alcoholism like a duck takes to water."

"And you know nothing of the child's parents?"

"Nothing, citizen. I had to go to Pantin once a month and have a look at him and report to citizen Marat. But I always had the same tale to tell. The child was looking more and more like a young reprobate every time I saw him."

"Did citizen Marat pay the Leridans for keeping the child?"

"Oh, no, citizen! The Leridans make a trade of the children by sending them out to beg. But this one was not to be allowed out yet. Citizen Marat's orders were very stern, and he was wont to terrify the Leridans with awful threats of the guillotine if they ever allowed the child out of their sight."

Chauvelin sat silent for a while. A ray of light had traversed the dark and tortuous ways of his subtle brain. While he mused the woman became impatient. She continued to talk on with the volubility peculiar to her kind. He paid no heed to her, until one phrase struck his ear.
