"Victory, mademoiselle!" she exclaimed, rapturously.
"Explain, if you please."
"Mademoiselle is aware that her dressing-room opens into my bedroom."
"Yes."
"And adjoining my chamber there is a large room containing the wardrobes for mademoiselle's dresses."
"Well?"
"There is a door in this room which opens upon a narrow staircase to which I never paid any attention before."
"And where does this staircase lead?"
"It leads down to a small door which has been closed up, but which opens, as nearly as I can judge, upon the side street."
"This door opens upon the street?" cried Mlle. de Beaumesnil, quickly.
