Context paragraphs:
The Sleep of Death: The Sleep of Death is a 1980 Swedish-Irish historical horror film directed by Calvin Floyd and starring Per Oscarsson, Curd Jürgens, Patrick Magee and Marilù Tolo.  It is based on the novel "The Room at the Flying Dragon" by Sheridan Le Fanu.  In 1815 at the end of the Napoleonic Wars, a young Englishman travels to France in pursuit of a woman.  Once there he begins to experience otherworldly events.  Its Swedish title is Ondskans Värdshus.

Alicia Le Fanu: Alicia Le Fanu (born 1791) was an Irish poet and writer.  She was the daughter of Elizabeth Sheridan and Captain Henry Le Fanu, and a granddaughter of actor Thomas Sheridan and his wife, writer Frances Sheridan.  She died, unmarried, sometime after 1844, in Dublin.  She was buried in the churchyard of St. Peter's Church, Aungier Street, Dublin, but the exact date of death is unknown.

Thomas Le Fanu: Thomas Philip Le Fanu (1784–1845) was an Irish Dean in the first half of the 19th century.  He was the son of Joseph Le Fanu and Alicia Sheridan, and the father of Joseph Sheridan Le Fanu.  He married Emma Lucretia Dobbin.

Carmilla: Carmilla is a Gothic novella by Joseph Sheridan Le Fanu and one of the early works of vampire fiction, predating Bram Stoker's "Dracula" (1897) by 26 years.  First published as a serial in "The Dark Blue" (1871–72), the story is narrated by a young woman preyed upon by a female vampire named Carmilla, later revealed to be Mircalla, Countess Karnstein (Carmilla is an anagram of Mircalla).  The story is often anthologized and has been adapted many times in film and other media.

The House by the Churchyard: The House by the Churchyard (1863) is a novel by Sheridan Le Fanu that combines elements of the mystery novel and the historical novel.  Aside from its own merits, the novel is important as a key source for James Joyce's "Finnegans Wake".

The Wyvern Mystery: The Wyvern Mystery is a 2000 BBC film starring Naomi Watts and Derek Jacobi.  The film is based on Sheridan Le Fanu's novel.

Uncle Silas: Uncle Silas, subtitled "A Tale of Bartram-Haugh", is a Victorian Gothic mystery-thriller novel by the Irish writer J. Sheridan Le Fanu.  Despite Le Fanu resisting its classification as such, the novel has also been hailed as a work of sensation fiction by contemporary reviewers and modern critics alike.  It is an early example of the locked room mystery subgenre, rather than a novel of the supernatural (despite a few creepily ambiguous touches), but does show a strong interest in the occult and in the ideas of Emanuel Swedenborg, a Swedish scientist, philosopher and Christian mystic.

Vampires vs. Zombies: Vampires vs. Zombies is an independent horror film loosely based upon J. Sheridan Le Fanu's classic 1872 novel "Carmilla".  Unlike Le Fanu's story, however, most of the action in the film takes place inside a car.  The title and the cover were obviously inspired by the horror film "Freddy vs. Jason", it's unclear if it was intended as a mockbuster of that film or not.

Sheridan Le Fanu: Joseph Thomas Sheridan Le Fanu ( ; 28 August 1814 – 7 February 1873) was an Irish writer of Gothic tales and mystery novels.  He was a leading ghost story writer of the nineteenth century and was central to the development of the genre in the Victorian era.  M. R. James described Le Fanu as "absolutely in the first rank as a writer of ghost stories".  Three of his best-known works are "Uncle Silas", "Carmilla" and "The House by the Churchyard".

Alicia Sheridan Le Fanu: Alicia Sheridan Le Fanu (1753–1817) was an Irish writer.  She was the daughter of actor Thomas Sheridan and his wife, writer Frances Chamberlaine Sheridan.  She was the sister of Richard Brinsley Sheridan and the aunt of writer Alicia LeFanu (with whom she is sometimes confused).
