Something Wicked assembles more than 560 horror classics, macabre tales, and supernatural mysteries into an expansive genealogy of dread. Moving from Gothic castles, revenants, doubles, and cursed objects to psychological terror, occult investigation, science-fictional menace, and mordant satire, the volume demonstrates horror's remarkable formal elasticity. Canonical narratives stand alongside rediscovered popular fiction, short sensational pieces, ghost stories, and uncanny experiments, revealing how fear has been imagined across centuries, nations, and literary registers. Its contributors span Romanticism, Victorian Gothic, sensation fiction, decadence, realism, modernism, and early speculative fiction. British, American, French, German, Russian, and other European traditions converge, while women writers, periodical authors, and figures associated with popular and pulp literature substantially broaden the archive beyond a narrow canon. Together these voices trace horror's engagement with imperial anxiety, gendered confinement, class instability, scientific change, spiritualism, criminality, and the limits of rational explanation. This is an invaluable volume for readers, students, and scholars seeking both immersion and comparative perspective. Its extraordinary breadth invites readers to follow recurring motifs across divergent styles and historical moments, while the juxtapositions foster a productive dialogue between celebrated masterpieces and less familiar curiosities. Something Wicked offers an education in the many languages of literary terror.
