"But you must sit down quietly," charged Aunt Peggy, "and you must learn your texts, to repeat to me when I get home." After Aunt Peggy and the old servant, in their great cloaks and bonnets and fur tippets, had gone out of the yard and down the road, Letitia sat quiet for fifteen minutes or so, hunting in the Bible for easy texts; then suddenly she thought of the little green door, and wondered, as she had done so many times before, if it could possibly be opened. She laid down her Bible and stole out through the kitchen to the cheese-room and tried the door. It was locked just as usual. "Oh, dear!" sighed Letitia, and was ready to cry. It seemed to her that this little green door was the very worst of all her trials; that she would rather open that and see what was beyond than have all the nice things she wanted and had to do without. Suddenly she thought of a little satin-wood box with a picture on the lid which Aunt Peggy kept in her top bureau-drawer. Letitia had often seen this box, but had never been allowed to open it. "I wonder if the key can be in that box," said she. She did not wait a minute. She was so naughty that she dared not wait for fear she should remember that she ought to be good. She ran out of the cheese-room, through the kitchen and sitting-room, to her aunt's bedroom, and opened the bureau drawer, and then the satin-wood box. It contained some bits of old lace, an old brooch, a yellow letter, some other things which she did not examine, and, sure enough, a little black key on a green ribbon. Letitia had not a doubt that it was the key of the little green door. She trembled all over, she panted for breath, she was so frightened, but she did not hesitate. She took the key and ran back to the cheese-room. She did not stop to shut the satin-wood box or the bureau drawer. She was so cold and her hands shook so that she had some difficulty in fitting the key into the lock of the little green door; but at last she succeeded, and turned it quite easily. Then, for a second, she hesitated; she was almost afraid to open the door; she put her hand on the latch and drew it back. It seemed to her, too, that she heard strange, alarming sounds on the other side. Finally, with a great effort of her will, she unlatched the little green door, and flung it open and ran out.
