The candle was instantly extinguished. In discreet silence the girls stole back to their beds, and listened. As an aid to the vigilance of the sentinel, the door had been left ajar. Through the narrow opening, a creaking of the broad wooden stairs of the old house became audible. In another moment there was silence. An interval passed, and the creaking was heard again. This time, the sound was distant and diminishing. On a sudden it stopped. The midnight silence was disturbed no more. What did this mean? Had one among the many persons in authority under Miss Ladd’s roof heard the girls talking, and ascended the stairs to surprise them in the act of violating one of the rules of the house? So far, such a proceeding was by no means uncommon. But was it within the limits of probability that a teacher should alter her opinion of her own duty half-way up the stairs, and deliberately go back to her own room again? The bare idea of such a thing was absurd on the face of it. What more rational explanation could ingenuity discover on the spur of the moment? Francine was the first to offer a suggestion. She shook and shivered in her bed, and said, “For heaven’s sake, light the candle again! It’s a Ghost.” “Clear away the supper, you fools, before the ghost can report us to Miss Ladd.” With this excellent advice Emily checked the rising panic. The door was closed, the candle was lit; all traces of the supper disappeared. For five minutes more they listened again. No sound came from the stairs; no teacher, or ghost of a teacher, appeared at the door. Having eaten her supper, Cecilia’s immediate anxieties were at an end; she was at leisure to exert her intelligence for the benefit of her schoolfellows. In her gentle ingratiating way, she offered a composing suggestion. “When we heard the creaking, I don’t believe there was anybody on the stairs. In these old houses there are always strange noises at night--and they say the stairs here were made more than two hundred years since.” The girls looked at each other with a sense of relief--but they waited to hear the opinion of the queen. Emily, as usual, justified the confidence placed in her. She discovered an ingenious method of putting Cecilia’s suggestion to the test. “Let’s go on talking,” she said. “If Cecilia is right, the teachers are all asleep, and we have nothing to fear from them. If she’s wrong, we shall sooner or later see one of them at the door. Don’t be alarmed, Miss de Sor. Catching us talking at night, in this school, only means a reprimand. Catching us with a light, ends in punishment. Blow out the candle.” Francine’s belief in the ghost was too sincerely superstitious to be shaken: she started up in bed. “Oh, don’t leave me in the dark! I’ll take the punishment, if we are found out.” “On your sacred word of honor?” Emily stipulated. “Yes--yes.” The queen’s sense of humor was tickled.
