Document 3: Lovecraftian horror: Lovecraftian horror is a subgenre of horror fiction that emphasizes the cosmic horror of the unknown (and in some cases, unknowable) more than gore or other elements of shock, though these may still be present. It is named after American author H. P. Lovecraft (1890–1937), who is largely credited as the first author to pioneer the genre.
Document 4: H. P. Lovecraft: Howard Phillips Lovecraft ( ; August 20, 1890 – March 15, 1937) was an American author who achieved posthumous fame through his influential works of horror fiction. He was virtually unknown and published only in pulp magazines before he died in poverty, but he is now regarded as one of the most significant 20th-century authors in his genre. Lovecraft was born in Providence, Rhode Island, where he spent most of his life. Among his most celebrated tales are "The Call of Cthulhu" and "The Shadow over Innsmouth", both canonical to the Cthulhu Mythos. Lovecraft was never able to support himself from earnings as author and editor. He saw commercial success increasingly elude him in this latter period, partly because he lacked the confidence and drive to promote himself. He subsisted in progressively strained circumstances in his last years; an inheritance was completely spent by the time that he died at age 46.

Lovecraft and first introduced in the short story "The Call of Cthulhu", published in the American pulp magazine "Weird Tales" in 1928. Considered a Great Old One within the pantheon of Lovecraftian cosmic entities, the creature has since been featured in numerous popular culture references. Lovecraft depicts Cthulhu as a gigantic entity worshipped by cultists. Cthulhu's appearance is described as looking like an octopus, a dragon and a caricature of human form. Its name was given to the Lovecraft-inspired universe where it and its fellow entities existed, the Cthulhu Mythos.

Document 11: Graham Greene: Henry Graham Greene (2 October 1904 – 3 April 1991), better known by his pen name Graham Greene, was an English novelist regarded by many as one of the great writers of the 20th century. Combining literary acclaim with widespread popularity, Greene acquired a reputation early in his lifetime as a major writer, both of serious Catholic novels, and of thrillers (or "entertainments" as he termed them). He was shortlisted, in 1966 and 1967, for the Nobel Prize for Literature. Through 67 years of writings, which included over 25 novels, he explored the ambivalent moral and political issues of the modern world, often through a Catholic perspective.
Document 12: The Mask of Dimitrios: The Mask of Dimitrios is a 1944 American film noir directed by Jean Negulesco and written by Frank Gruber, based on the 1939 novel of the same name written by Eric Ambler (in the United States, it was published as "A Coffin for Dimitrios"). Ambler is known as a major influence on writers and a developer of the modern thriller genre.
Document 13: Cthulhu Mythos: The Cthulhu Mythos is a shared fictional universe, based on the work of American horror writer H. P. Lovecraft. The term was coined by August Derleth, a contemporary correspondent and protégé of Lovecraft's, to identify the settings, tropes, and lore employed by Lovecraft and his literary successors. The name "Cthulhu" derives from the central creature in Lovecraft's seminal short story, "The Call of Cthulhu", first published in the pulp magazine "Weird Tales" in 1926. Richard L. Tierney, a writer who also wrote "Mythos" tales, later applied the term "Derleth Mythos" to distinguish Lovecraft's works from Derleth's later stories, which modify key tenets of the "Mythos". Authors of Lovecraftian horror in particular frequently use elements of the Cthulhu Mythos.

He is widely regarded as a central figure of Romanticism in the United States and American literature as a whole, and he was one of the country's earliest practitioners of the short story. Poe is generally considered the inventor of the detective fiction genre and is further credited with contributing to the emerging genre of science fiction. He was the first well-known American writer to try to earn a living through writing alone, resulting in a financially difficult life and career.
