So with this in mind, obliterating all other thoughts at their hour of retiring, for the first evening since their fright ten days before, neither Polly nor Betty remembered the locking of their outside door upon getting into bed. And this time it was Polly O'Neill who was aroused first a short while after midnight by the slow turning of their doorknob and then the sense of an almost noiseless figure entering their bedroom. Immediately she awoke Betty by suddenly calling her name aloud, and at the same instant sprang out of bed, again touching the electric button and flooding the room with revealing light. CHAPTER XX THE BEGINNING OF LIGHT "Why, why!" exclaimed Polly in surprise and consternation, standing perfectly still with her hand upraised toward the light, too puzzled to let it drop down at her side. But with a little, warning cry Betty had called to her and almost at the same moment was across the room, with her arms about a tall, slight figure. "Mother, mother," she whispered quietly, "wake up. You have gotten up out of your bed and wandered into Polly's and my room. And you have frightened us nearly to death! Dear me, you have not walked in your sleep for years, have you?" At Betty's first words following the stream of light, Mrs. Ashton had opened her eyes with returning consciousness until now she appeared almost entirely wide awake. And an expression both of fear and annoyance crossed her face. "You poor children, so I am your ghost and your burglar," she declared, "and I believed it was you who were having nightmares! I am awfully sorry. Betty knows I used to have this unfortunate habit of strolling about the house in my sleep long ago. But I am quite sure that I have not done it for several years now. The truth is I have not yet gotten over the nervous shock of Betty's being brought home to me and my not knowing how seriously she was injured for such a time; it seemed an eternity." Betty had thrown a shawl over her mother's shoulders, as she was clad only in her night-dress, and she and Polly slipped into their dressing gowns. "Wasn't it odd, though, mother, your coming in here both times? I wonder if you had me on your mind and wanted to see how I was. But you did not seem to. You kept groping your way toward that old closet as though you wished to rummage about in it. But do come and let me take you back to bed now, and I will stay with you so you will behave yourself and give Polly a chance to rest." For quite five minutes after the two had gone, Polly lay awake. There were really so many things to consider, because, of course, when one has too active an imagination it is apt to lead one into trouble. First, she must apologize to Anthony Graham for her totally unfounded suspicion of him. And then, thank Heaven, she had not breathed the suggestion aloud! Yet just for a moment she had wondered if Edith Norton could have--but it was not true and of course never could have been.
