Dorothy leaned forward to look across Hester's desk at her sister. She was anxious that Dora should not fail. She would have imparted, could she have done so, her knowledge of Saladin to her twin. But there was only nervous anxiety in her look and manner. The moment Dora's lips opened and she began her reply, Hester turned sharply and stared at Dorothy. It was a despicable trick--a mean and contemptible attempt to get the twins into trouble. And Hester did it deliberately. She knew that Miss Carrington was much more near-sighted than she was willing to acknowledge. Seeing Hester look at Dorothy caused the teacher to believe that Dorothy was answering for her sister. "Stop!" commanded Miss Carrington, rising quickly from her seat on the platform. Dora, who had begun very well at last, halted in her answer and looked surprised. Miss Carrington was glaring now at Dorothy. "How dare you, Dorothy Lockwood?" she demanded, her face quite red with anger. "There is no trusting any of you girls. Cheat!" There was a sudden intake of breath all over the room. Some of the girls looked positively horror-stricken. For the teacher to use such an expression shocked Laura, and Jess, and Nellie for an instant, as though the word had been addressed to them personally. "Oh!" gasped Jess. The teacher flashed her a glance. "Silence, Miss Morse!" Dorothy had risen slowly to her feet. "What--what do you mean, Miss Carrington?" she whispered. "Do you say I--I have _cheated?"_ "Cheat!" repeated the teacher, with an index finger pointing Dorothy down. "I saw you. I heard you. You started to answer for your sister." "I did not!" cried the accused girl. "She certainly did not, Miss Carrington!" repeated Dora, rising likewise. "Silence!" exclaimed Miss Carrington. "I would not believe either of you. You are both disgracing your classmates and Central High." A sibilant hiss rose in the back of the room. The girls were more angry at this outburst of the teacher than all of them dared show. Dorothy burst into a fit of weeping. She covered her face with her hands and ran out of the room. Dora, defying Miss Carrington, muttered: "Ugly, mean thing!" Then she ran after her sister. The room was in tense excitement. Miss Carrington saw suddenly that she positively had nobody on her side. She began to question the girls immediately surrounding the twins' seats. "You saw her answer for her sister, Miss Morse?" "I did not," declared Jess icily. "Were you not looking at Dorothy, Laura?" asked the teacher. "No, Miss Carrington. I was looking at Dora." "And Dora answered!" cried the usually gentle and retiring Nellie Agnew. "Why----Miss Grimes!" exclaimed the disturbed teacher. "You know that Dorothy was answering for her sister?" "Oh, no, Miss Carrington," denied Hester. "But you looked at her?" "Yes." "What for?" snapped the teacher. "Why," drawled Hester, "that pin Dorothy wears in her blouse was on crooked and it attracted my attention."
