"She does not live here,—it's opposite," said Rodolph.

"Thank ye, master. They told me the left-hand door; but I've mistook."

Rodolph did not recollect the name of the diamond-matcher, which Morel the lapidary had only mentioned once or twice, and thus had no motive for interesting himself in the female to whom Barbillon came with his message; but yet, although ignorant of the ruffian's crimes, his face was so decidedly repulsive that he remained at the threshold of the door, curious to see the person to whom Barbillon brought the letter.

Barbillon had scarcely knocked at the door opposite to Germain's, than it opened, and the jewel-matcher, a stout woman of about fifty, appeared with a candle in her hand.

"Ma'am Mathieu?" inquired Barbillon.

"That's me, my man."

"Here's a letter, and I waits for an answer."

And Barbillon made a step forward to enter the doorway, but the woman made him a sign to remain where he was, and unsealed the letter, which she read by the light of the candle she held, and then replied with an air of satisfaction:

"Say it's all right, my man, and I will bring what is required. I will be there at the same hour as usual. My respects to the lady."

"Yes, missus. Please to remember the porter!"
