Elizabeth was watching her and noticed her pallor and swaying body. "What is the matter, Jean? What has happened? This isn't a bit like you. Can I help you?" "No, Elizabeth; I shall be all right as soon as I get upstairs. Please don't leave until the others do." Then she crept up the stairs and when she entered her own room she closed the door and locked it. She quickly tore off the two costumes, leaving the black one on the couch where Elizabeth would be sure to see it; then she threw the Old Mother Hubbard dress into a trunk which was in her closet, closed the lid, and locked it. Putting on her kimona she sat down to think and wait for the girls to come upstairs. When Elizabeth entered the room, Jean was more like herself and talked gayly about the girls' costumes. "I'll go out in the corridor and put out the lights, and I've got a message to deliver to one of the girls, so don't wait up for me." She put out all the lights on fourth floor and then walked slowly up and down the corridor three or four times before knocking softly at Marjorie's door. Without waiting for her to reply, Jean entered the room and closed the door gently after her. "Marjorie, remember I come here to-night as proctor as well as friend. What you have done is awful. I can hardly think about it calmly. How did you dare think of such a thing? You've broken every rule of our house, you've deceived every girl here and Mrs. Thompson as well, you've committed an offense worthy of expulsion, you've disgraced yourself and all the rest of us. Now what's to be done? I'm the only girl who knows what has happened, although others were mystified at my being the monk and the Mother Hubbard, too. That will be forgotten in a day or two, but what you have done is of more serious import. You wonder why I dressed up in Jack's costume? I was tired of dancing and went out into the cozy corner beyond the lemonade table to rest a little. Before I had been there long you and Jack came and I could not help overhearing your conversation. After he had gone I knew you would go back to the other rooms alone and every one would wonder where your constant attendant had gone. Questions would be asked and you would have to give some sort of an explanation. The idea came to me to put on Jack's costume for the remainder of the evening and save you from a difficult position. Now I have given you an explanation of my conduct and I ask for one of yours."
