The Castle of Otranto is regarded as the first Gothic novel. The son of Manfred, Prince of Otranto, is mysteriously killed on his wedding day by a huge helmet. The event leads to a fast-paced story of jealous passion, intrigue, murder and supernatural phenomena unfolding in an atmosphere of thunderclaps, moonlight, and dark castle walls - mirroring the inner turmoils of the characters themselves. Horace Walpole's tale, an immediate success when it first appeared in 1764, is a classic of its genre.
