open by day but generally closed at night. The door yielded. Both entered, and found themselves in darkness; but Mme. Bonacieux was acquainted with all the turnings and windings of this part of the Louvre, appropriated for the people of the household. She closed the door after her, took the duke by the hand, and after a few experimental steps, grasped a balustrade, put her foot upon the bottom step, and began to ascend the staircase. The duke counted two stories. She then turned to the right, followed the course of a long corridor, descended a flight, went a few steps farther, introduced a key into a lock, opened a door, and pushed the duke into an apartment lighted only by a lamp, saying, “Remain here, my Lord Duke; someone will come.” She then went out by the same door, which she locked, so that the duke found himself literally a prisoner.
