The trip was not long. A few minutes later the magic plane was under a big old tree. Sarah was in the middle of the Wild Wood. She didn't know where to go. "How can I get out of here?" she asked. "Can't you find the road?" she suddenly heard a voice. She looked up and down, but couldn't see anybody. There was just an ugly old tree near to where she stood. Then she heard the voice again.

"Certainly not," said the tree. "You, young people, must learn to work without help. Well, hurry up! And he shook his leaves sadly. Sarah went straight ahead. It was difficult to walk because it was dark. She wanted to take a bus , but there were no buses in the Wild Wood. So she had to go on foot. It was a long way. By the time she saw the Witch's house it was already morning. She went up to the castle and saw that the key was in the door. She opened it and went in." Come up here!" she heard a voice from upstairs. She went up and there she saw a large room. In the middle of this room there was a fire burning. In front of the fire there were two armchairs, and in one of them was an ugly old witch. Her friendly black cat, Midnight, was in the other.-
