Marcia pried and pried, stopping now and then to look about her and listen, as if afraid of being caught; and at last fished up from between the stones something glittering which looked like--was it possible?--Dora thought it looked like a slender chain with something hanging to it. Could it be?--was it--Belle's locket? She darted from her corner, along the piazza, down the steps leading to the garden, and around to the side of the wall where Marcia was; but the girl saw and heard her coming, and before she reached her the thing she had held in her hand was dropped again into its hiding-place between the stones. Yet not so quickly but that Dora saw the motion of Marcia's hand, and she was more than ever convinced that something was wrong. They stood and faced one another, the little lady and the colored girl: the former, stern and indignant, as became one who had caught a culprit in the act; the other, sheepish and guilty, wriggling her shoulders uneasily, and not daring to meet the eye which accused her. "Give me that," said Dora, severely. "Give you what, Miss Johnson?" said Marcia, twisting and wriggling more than ever and vainly trying to put on an air of innocence. "What you had in your hand. I b'lieve you've put it back in the wall, but you'll have to let me see it," said Dora. "I ain't got nothin', Miss; and I s'pect Miss Ashton wants you. I hear her callin'," said Marcia. "She's not calling, and if she was I wouldn't go till I knew what that was," answered Dora, firmly. "She'll excuse me when I tell her why." Marcia persisted, and insisted that she had had nothing in her hand; but Dora knew better. And though the girl tried every device to rid herself of the young lady, she was not to be moved. She would mount guard over that hidden thing till she learned what it was, if she stood there all day. Equally determined was Marcia; but she coaxed and threatened and tried to frighten in vain. Dora was a child of too much sense to be at all disturbed by the stories she told of what would happen to her; treated with scorn all the bribes which Marcia promised; and repeated over and over again her resolution not to stir till she saw what was in that crack. As for Miss Ashton coming for her, it was just what Dora wished for: she could tell her teacher, and leave the matter in her hands, sure that she would find means of coming at the truth. And now there was Nelly Ransom's voice making itself heard. "Dora! Dora! Where are you? Miss Ashton wants to know if you are worse." "Come here, Nelly," said Dora; while Marcia grew more and more uneasy as she found the toils of her own wickedness closing down and down upon her. "You go and ask Miss Ashton to come here very quick. I've made a great discovery. Make haste." Nelly obeyed, wondering much; and Miss Ashton, rather alarmed, speedily appeared on the spot.
