“Ah, I forgot,” said Madame Henrietta, “I forgot the secret spring; the fourth plank of the flooring,—press on the spot where you will observe a knot in the wood. Those are the instructions; press, vicomte! press, I say, yourself.”

Raoul, pale as death, pressed his finger on the spot which had been indicated to him; at the same moment the spring began to work, and the trap rose of its own accord.

“It is ingenious enough, certainly,” said the princess; “and one can see that the architect foresaw that a woman’s hand only would have to make use of this spring, for see how easily the trap-door opened without assistance.”

“A staircase!” cried Raoul.

“Yes, and a very pretty one, too,” said Madame Henrietta. “See, vicomte, the staircase has a balustrade, intended to prevent the falling of timid persons, who might be tempted to descend the staircase; and I will risk myself on it accordingly. Come, vicomte, follow me!”

“But before following you, madame, may I ask where this staircase leads to?”

“Ah, true; I forgot to tell you. You know, perhaps, that formerly M. de Saint-Aignan lived in the very next apartment to the king?”

“Yes, Madame, I am aware of that; that was the arrangement, at least, before I left; and more than once I had the honor of visiting his rooms.”

“Well, he obtained the king’s leave to change his former convenient and beautiful apartment for the two rooms to which this staircase will conduct us, and which together form a lodging for him half the size, and at ten times greater the distance from the king,—a close proximity to whom is by no means disdained, in general, by the gentlemen belonging to the court.”

“Very good, Madame,” returned Raoul; “but go on, I beg, for I do not understand yet.”
