Simon was very excited as he came into my laboratory. "O my dear fellow!" he gasped. "I have just seen the most amazing thing in the world!" He told me he had gone to visit a woman who had strange, magical powers. She could speak to the dead and read the minds of the living. To test her, Simon had written some questions about himself on a piece of paper. The woman, Madame Vulpes, had answered all of the questions correctly. Hearing about the woman gave me an idea. Perhaps she would be able to help me discover the secret of the perfect lens. Two days later, I went to her house. Madame Vulpes was an ugly woman with sharp, cruel eyes. She didn't say a word to me when she opened the door, but took me right into her living room. We sat down at a large round table, and she spoke. "What do you want from me?" "I want to speak to a person who died many years before I was born." "Put your hands on the table." We sat there for several minutes. The room grew darker and darker. But Madame Vulpes did not turn on any lights. I began to feel a little silly. Then I felt a series of violent knocks. They shook the table, the back of my chair, the floor under my feet and even the windows.
