The children did not know at first what they had especially to tell to Mademoiselle; but that clever woman was not ten minutes in their society before she had obtained a vast lot of useful information from them—information which she meant to turn to good account. She had her way to make in the world, and could only make it by more or less dishonest means. In short, before she left the little girls on this occasion, she knew that little secret with regard to Nina’s account-book, and why Nina was learning this salutary lesson. She pretended to be rather shocked by the little girl’s disclosure.

“Oh, mais fi donc! mon enfant,” she exclaimed. “You to have had that very great mistrust! and your beautiful instructress has the anxiety written all over her face. She punishes you, and it is well. Doubtless it is also for that very reason that she confines you and your sister in this so triste appartement, while she and Fanchon go abroad in order to amuse themselves. But, my dear petites, I have not come to this house for nothing. I would aid you. I see not why you two poor little ones should not also have your so great pleasure. What would you say to coming out with me for a little pastime to-morrow evening?”

“We would love it beyond anything!” said Joey. “But,” said Nina, “we would not dare!”

“And why not, petites, if no person did know it?”

“Surely you could not manage that?”

“Ah—but yes; I think I know a way. I would you advise to slip into bed to-morrow evening with a willing grace; but put on your night things over your pretty day garments, so that you can slip them off quickly when I appear. I will then take you abroad for a delicious hour. We will go out and see the wonders of the night, and you will be in bed again and, peut-être, asleep, before Mademoiselle Brenda and Mademoiselle Fanchon appear.”

This sounded delicious, daring, extremely naughty, and altogether quite impossible to resist, to the little girls.

“You are quite a darling,” said Nina. “I only wish you were our governess instead of horrid Brenda!”

“Ah, méchante—but Brenda, whom you like not, is of the best. She has the principles the most high, and the desires the most perfect for your real advancement.”

“I don’t think so for a single minute,” said Nina.
