A Study in Scarlet is a 1887 detective novel by British author Arthur Conan Doyle. Written in 1886, the story marks the first appearance of Sherlock Holmes and Dr. Watson, who would become two of the most famous characters in popular fiction. The book's title derives from a speech given by Holmes, an amateur detective, to his friend and chronicler Watson on the nature of his work, in which he describes the story's murder investigation as his "study in scarlet": "There's the scarlet thread of murder running through the colourless skein of life, and our duty is to unravel it, and isolate it, and expose every inch of it."

"The Cask of Amontillado" (sometimes spelled "The Casque of Amontillado") is a short story by Edgar Allan Poe, first published in the November 1846 issue of Godey's Lady's Book. The story, set in an unnamed Italian city at carnival time in an unspecified year, is about a man taking fatal revenge on a friend who, he believes, has insulted him. Like several of Poe's stories, and in keeping with the 19th-century fascination with the subject, the narrative revolves around a person being buried alive - in this case, by immurement. As in "The Black Cat" and "The Tell-Tale Heart", Poe conveys the story from the murderer's perspective. Cover by the lovely @theygotnone
