Strange Case of Dr. Jekyll and Mr. Hyde Chapter 9

By Robert Louis Stevenson

Chapter 9

  • Dr. Lanyon receives a letter from Dr. Jekyll asking him, in the name of their long and esteemed friendship, to perform a complicated favor.
  • The favor involves breaking and entering into Dr. Jekyll’s laboratory and giving some potions to a messenger who will arrive at Dr. Lanyon’s house at midnight.
  • Dr. Lanyon does as the letter requests.
  • Mr. Hyde shows up, eager to take the chemicals. He’s wearing clothes that are much too big for him.
  • He takes the chemicals and transforms into Dr. Henry Jekyll.
  • This is quite a disturbing sight, especially for a man of science such as Dr. Lanyon.
