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 the fin de siecle gothic revival. Marshs work spans a range of gothic modes including the canonical fin de siecle subgenres of urban and imperial gothic and gothicinflected 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 narrative The Beetle A Mystery a novel that articulated many of the key themes of fin de siecle urban gothic and outsold its close rival Bram Stokers Dracula well into the twentieth century. The present work extends studies of Marshs literary production beyond The Beetle contending that in addition to his undoubted interest in nonnormative 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.
