Richard Marsh (Richard Bernard Heldmann, 18571915) was a bestselling, versatile and prolific author of gothic, crime, adventure, romantic and comic fiction. This book, the first on Marsh, establishes his credentials as a significant agent within thefin de siècle gothic revival. Marshs work spans a range of gothic modes, including the canonicalfin de siècle subgenres of urban and imperial gothic and gothic-inflected sensation and supernatural fiction, but also rarer hybrid genres such as the comic gothic and the occult romance. His greatest success came in 1897 when he published his bestselling invasion narrativeThe Beetle: A Mystery, a novel that articulated many of the key themes offin de siècle urban gothic and outsold its close rival, Bram StokersDracula, well into the twentieth century. The present work extends studies of Marshs literary production beyondThe Beetle, contending that, in addition to his undoubted interest in non-normative gender and ethnic identities, Marsh was a writer with an acute sense of spatiality, whose fiction can be read productively through the lens of spatial theory.
