Read the excerpt from The Secret Garden. She put her hand accidentally upon the tapestry near her, and then sprang back, feeling
quite startled. The tapestry was the covering of a door which fell open and showed her that there was another part of the corridor behind it, and Mrs. Med-lock was coming up it with her bunch of keys in her hand and a very cross look on her face. “What are you doing here?” she said, and she took Mary by the arm and pulled her away. “What did I tell you?” “I turned round the wrong corner,” explained Mary. “I didn’t know which way to go and I heard someone crying.” She quite hated Mrs. Medlock at the moment, but she hated her more the next. “You didn’t hear anything of the sort,” said the housekeeper. “You come along back to your own nursery or I’ll box your ears.” And she took her by the arm and half pushed, half pulled her up one passage and down another until she pushed her in at the door of her own room. “Now,” she said, “you stay where you’re told to stay or you’ll find yourself locked up. The master had better get you a governess, same as he said he would. You’re one that needs someone to look sharp after you. I’ve got enough to do.” She went out of the room and slammed the door after her, and Mary went and sat on the hearth-rug, pale with rage. She did not cry, but ground her teeth. “There was someone crying—there was—there was!” she said to herself. She had heard it twice now, and sometime she would find out. She had found out a great deal this morning. She felt as if she had been on a long journey, and at any rate she had had something to amuse her all the time, and she had played with the ivory elephants and had seen the gray mouse and its babies in their nest in the velvet cushion. Which evidence best supports the idea that Mrs. Medlock is hiding something from Mary? "'You didn't hear anything of the sort...'" "'She went out of the room and slammed the door after her...'" "'You’re one that needs someone to look sharp after you. I’ve got enough to do.'"
Well, it represents their key of achieving their long term dreams. It can also symbolize Walters greed and the destruction to his own original beliefs.
