That night I became a mad man, and beat Sir Danvers to death for no reason at all. I felt only a wild delight as I hit his body again and again. Afterwards I ran to the flat and destroyed all my papers. I was not ashamed of my crime. Instead I was filled with a high, sweet excitement. I relived the murder as I walked back home through the streets. I felt strong and masterful…Edward Hyde had a song on his lips as he mixed a dose of the drug. 'Your very good health, Sir Danvers!' he laughed as he drank. A moment of terrible pain, then poor Henry Jekyll fell to his knees and begged God to forgive him.

When I was myself again, I locked the door that led from the street to my laboratory. I broke the key and threw it away. Goodbye forever, Mr Hyde! I whispered.
