The Castle of Otranto is a 1764 novel by Horace Walpole. It is generally held to be the first gothic novel, initiating a literary genre which would become extremely popular in the later 18th century and early 19th century. Thus, Castle, and Walpole by extension is arguably the forerunner to such authors as Ann Radcliffe, Bram Stoker, Daphne du Maurier, and Stephen King. (Summary by Wikipedia)
