She could have done it, had she been in possession of her accustomed faculties. But between the harrowing suspicion that engrossed her mind and the nervous moisture that gathered in her eyes with each step, she mounted a story too high, and did not perceive her blunder until, happening to think that her apartment must lie somewhere in the region she had gained, she consulted the numbers upon the adjacent doors, and saw that she had wandered a hundred rooms out of her way, She stopped short to consider which of the corridors, stretching in gas-lit vistas on either hand, would conduct her soonest to the desired haven, when a gentleman emerging from a chamber close by stepped directly upon her train.
