A lady who looked some forty years of age, plainly dressed, but of distinguished appearance, was thereupon ushered into the room. Like any well-bred modiste, she bowed respectfully while the servant was present, but as soon as he had left the room she approached Mademoiselle Marguerite and took hold of her hands: “My dear young lady,” said she, “I am the sister-in-law of your old friend, the magistrate. Having an important message to send to you, he was trying to find a person whom he could trust to play the part of a dressmaker, as had been agreed upon between you, when I offered my services, thinking he could find no one more trusty than myself.” Tears glittered in Mademoiselle Marguerite’s eyes. The slightest token of sympathy is so sweet to the heart of the lonely and unfortunate! “How can I ever thank you, madame?” she faltered. “By not attempting to thank me at all, and by reading this letter as soon as possible.” The note she now produced ran as follows: “MY DEAR CHILD--At last I am on the track of the thieves.

Courage!” “Well!” said the spurious dressmaker, when she saw that Marguerite had finished reading the letter. “What answer shall I take my brother-in-law?” “Tell him that he shall certainly have the information he requires to-morrow. To-day, I can only give him the name of the carriage builder, from whom M. de Fondege has purchased his new carriages.” “Give it to me in writing, it is much the safest way.” Mademoiselle Marguerite did so, and her visitor who, as a woman, was delighted to find herself mixed up in an intrigue, then went off repeating the old magistrate’s advice: “Courage!”
