He wanted to know whom he hated.

To his great astonishment, the door opened and Christine Daae appeared, wrapped in furs, with her face hidden in a lace veil, alone.

She closed the door behind her, but Raoul observed that she did not lock it.

When the passage was once more deserted, he crossed it, opened the door of the dressing-room, went in and shut the door.
