Many of Sir Arthur Conan Doyle's mysteries begin with lengthy expositions, setting up the backstory for the case, so that the detective can begin his investigation. Such is the case in "The Adventures of the Speckled Band," in which Sherlock Holmes must get to the bottom of the mysterious death of Helen Stoner's sister, Julia. The rising action begins after Holmes has an extensive interview with Helen to get all the details of the case.
After Holmes talks to Helen, Dr. Grimesby Roylott confronts Holmes about their conversation, and the rising action begins. Holmes goes to Roylott's family home, Stoke Moran, to investigate. Helen is staying at the home and sleeping in the same room where her sister died. With each odd thing that Holmes finds -- such as a bed clamped to the floor and medical equipment that does not work -- more information is revealed, and the tension builds. After thoroughly investigating, Holmes says he has figured out what happened and asks Helen to sleep in another room. Without Roylott's knowledge, Holmes and Watson stay in her room for the night to test Holmes' hypothesis, building the tension of the story. In the climax, the murderer is revealed, and Holmes' theory is proven correct.
