VIII The Adventure of the Speckled Band [UNABRIDGED AUDIOBOOK WITH TEXT]

A young woman named Helen Stoner consults the detective Sherlock Holmes about her ill-tempered and immensely strong stepfather, Dr. Grimesby Roylott. He has required her to move into a particular room of his heavily mortgaged ancestral home, Stoke Moran. The room has some very odd features, such as a bed bolted to the floor. It is also the room that Stoner's twin sister, Julia, had slept in when she died under suspicious circumstances. Julia had been engaged to be married and had she lived would have received a L250 pound annuity from her late mother's income.

A number of other details about the place are mysterious and disturbing. A low whistling sound is heard late at night, as well as a metallic clank. There is a strange bell cord over the bed, and it does not seem to work any bell. There are also Julia's dying words about a "speckled band"...
