"I read all my books, dear. Including the old ones...Old ones with old magic in them. And getting a sample of your hair was rather easy..."
"What are you talking about?" Sarah said. Suddenly, a massive headache came on. She closed her eyes against the pain.
When she opened them, Mrs. Finch's glasses were on her face. She tried taking them off, but the world became a blur.
Mrs. Finch was looking around with satisfaction. "I haven't been able to see without glasses since I was ten," she said. "Oh, you can walk around, if you'd like. But you'll find you can't leave the room."
"What are you doing to me?"
"To you...that is why I chose you. You are a self-centered little brat."
"Chose me for what?"
"My replacement, of course. And I'll go off and learn about all this technology they seem to think is more important than books and be back. You may even still be here," Mrs. Finch said.
"Let me go, you senile old bat."
"Now, now...best not to lose your temper."
Sarah started to respond when she felt another headache coming on.
