Louisa looked amazed. Never before had Mary Isabel set her decrees at naught.
"Are you crazy, Mary Isabel?" she demanded.
"No, I am not crazy. But I am going to town and I am going to get a silver-grey silk for myself and a new hat. I will not wear a bonnet and you need never mention it to me again, Louisa."
"If you are going to town I shall stay home," said Louisa in a cold, ominous tone that almost made Mary Isabel quake. If it had not been for that reassuring crackle of Tom's letter I fear Mary Isabel would have given in. "This house can't be left alone. If you go, I'll stay."
Louisa honestly thought that would bring the rebel to terms. Mary Isabel had never gone to town alone in her life. Louisa did not believe she would dare to go. But Mary Isabel did not quail. Defiance was not so hard after all, once you had begun.
Mary Isabel went to town and she went alone. She spent the whole delightful day in the shops, unhampered by Louisa's scorn and criticism in her examination of all the pretty things displayed. She selected a hat she felt sure Tom would like—a pretty crumpled grey straw with forget-me-nots and ribbons. Then she bought a grey silk of a lovely silvery shade.
When she got back home she unwrapped her packages and showed her purchases to Louisa. But Louisa neither looked at them nor spoke to Mary Isabel. Mary Isabel tossed her head and went to her own room. Her draught of freedom had stimulated her, and she did not mind Louisa's attitude half as much as she would have expected. She read Tom's letter over again to fortify herself and then she dressed her hair in a fashion she had seen that day in town and pulled out all the little curls on her forehead.
The next day she took the silver-grey silk to the Latimer dressmaker and picked out a fashionable design for it. When the silk dress came home, Louisa, who had thawed out somewhat in the meantime, unbent sufficiently to remark that it fitted very well.
"I am going to wear it to the induction tomorrow," Mary Isabel said, boldly to all appearances, quakingly in reality. She knew that she was throwing down the gauntlet for good and all. If she could assert and maintain her independence in this matter Louisa's power would be broken forever.
