In five to six sentences, summarize the events in "Dr. Lanyon’s Narrative.” Think about the chapter’s important details and events.

Answer:

Dr. Lanyon receives a letter from Dr. Jekyll desperately asking him to retrieve a specific drawer from Jekyll's laboratory. Lanyon follows the instructions, takes the drawer home, and awaits a visitor who arrives at midnight. This visitor, a small and disturbing man, creates a chemical mixture using the ingredients from the drawer. After drinking the potion, the man agonizingly transforms into Dr. Jekyll right before Lanyon’s eyes. This shocking revelation that Jekyll and Hyde are the same person causes Lanyon to fall into a state of physical and mental decline.
