I saw them so plain in the moonlight ! '' `` Now lie down , dear little Carrie , till I find out what all this means , '' said Agnes . The weeping child obeyed , hugging up close to her little sister for protection . The light had been taken away at ten o'clock , as was the invariable custom at Mrs. Arlington 's ; but Agnes opened both shutters , and admitted the bright moonlight into the room , making every object to be discerned almost as plainly as in the day-time . She then stepped to her own bed . Miss Glenn certainly was not there . She went to the door of her room , and found it locked on the inside , as she had left it when she went to bed .
