One evening, in 18-, I was in Rome and was invited to a big party in the palace of Duke Di Broglio.The Duke was old and boring, but his wife was young and beautiful, and not very sensible.I had evil plans for her.She and I had agreed to meet, during the party, in a quiet room where we could be alone.As I walked from room to room looking for her in the crowds, I suddenly felt a hand touch my arm.Then I heard a whisper in my ears.Angrily I turned round and saw a man.He was wearing the same clothes as I was, but his face was covered with a black mask.I caught him by his arm. 'Stop!' I shouted."I have had enough trouble from you! This is the last time you'll follow me anywhere! Come with me now into the next room.If you don't, I shall kill you right now, here where you stand!’I took him into a small room nearby and pushed him violently to the floor.He got to his feet shakily, and stood up against the wall.
