Our story is called "The Diamond Lens. " It was written by Fitz-James O'Brien. Today we will hear the second and final part of the story. Here is Maurice Joyce with part two of "The Diamond Lens."When I was a child, someone gave me a microscope. I spent hours looking through that microscope, exploring Nature's tiny secrets. As I grew up, I became more interested in my microscope than in people.When I was twenty years old, my parents sent me to New York City to study medicine. I never went to any of my classes. Instead, I spent all my time, and a lot of my money, trying to build the perfect microscope. I wanted to make a powerful lens that would let me see even the smallest parts of life. But all my experiments failed.Then one day, I met a young man, who lived in the apartment above mine. Jules Simon told me about a woman who could speak to the dead. When I visited Madame Vulpes, she let me speak to the spirit of the man who invented the microscope. The spirit of Anton Leeuwenhoek told me how to make a perfect lens from a diamond of one hundred forty carats.But where could I find a diamond that big?When I returned home, I went to Simon's apartment. He was surprised to see me and tried to hide a small object in his pocket. I wanted to discover what it was, so I brought two bottles of wine to his apartment. We began to drink. By the time we had finished the first bottle, Simon was very drunk."Simon, I know you have a secret. Why don't you tell me about it?" Something in my voice must have made him feel safe. He made me promise to keep his secret. Then he took a small box from his pocket. When he opened it, I saw a large diamond shaped like a rose. A pure white light seemed to come from deep inside the diamond.Simon told me he had stolen the diamond from a man in South America. He said it weighed exactly one hundred forty carats.Excitement shook my body. I could not believe my luck. On the same evening that the spirit of Leeuwenhoek tells me the secret of the perfect lens, I find the diamond I need to create it.I decided to steal Simon's treasure.I sat across the table from him as he drank another glass of wine. I knew I could not simply steal the diamond. Simon would call the police. There was only one way to get the diamond. I had to kill Simon.Everything I needed to murder Simon was right there in his apartment. A bottle full of sleeping powder was on a table near his bed. A long thin knife lay on the table. Simon was so busy looking at his diamond that I was able to put the drug in his glass quite easily. He fell asleep in fifteen minutes.I put his diamond in my pocket and carried Simon to the bed. I wanted to make the police think Simon had killed himself. I picked up Simon's long thin knife and stared down at him. I tried to imagine exactly how the knife would enter Simon's heart if he were holding the knife himself.I pushed the knife deep into his heart. I heard a sound come from his throat, like the bursting of a large bubble. His body moved and his right hand grabbed the handle of the knife. He must have died immediately.I washed our glasses and took the two wine bottles away with me. I left the lights on, closed the door and went back to my apartment.Simon's death was not discovered until three o'clock the next day. One of the neighbors knocked at his door and when there was no answer, she called the police. They discovered Simon's body on the bed. The police questioned everyone. But they did not learn the truth. The police finally decided Jules Simon had killed himself, and soon everyone forgot about him. I had committed the perfect crime.
