Lady Chatterley's Lover is a novel by D. H. Lawrence, first published privately in 1928 in Italy, and in 1929 in France and Australia. An unexpurgated edition was not published openly in the United Kingdom until 1960, when it was the subject of a watershed obscenity trial against the publisher Penguin Books. Penguin won the case, and quickly sold 3 million copies. The book was also banned for obscenity in the United States, Canada, Australia, India and Japan. The book soon became notorious for its story of the physical (and emotional) relationship between a working class man and an upper class woman, its explicit descriptions of sex, and its use of then-unprintable words.

"The Murders in the Rue Morgue" is a short story by Edgar Allan Poe published in Graham's Magazine in 1841. It has been recognized as the first modern detective story; Poe referred to it as one of his "tales of ratiocination". C. Auguste Dupin is a man in Paris who solves the mystery of the brutal murder of two women. Numerous witnesses heard a suspect, though no one agrees on what language was spoken. At the murder scene, Dupin finds a hair that does not appear to be human. As the first fictional detective, Poe's Dupin displays many traits which became literary conventions in subsequent fictional detectives, including Sherlock Holmes and Hercule Poirot. Many later characters, for example, follow Poe's model of the brilliant detective, his personal friend who serves as narrator, and the final revelation being presented before the reasoning that leads up to it. Dupin himself reappears in "The Mystery of Marie Rogêt" and "The Purloined Letter".
