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.
