Ann Radcliffe (1764-1823), author of the first true Gothic romance The Mysteries of Udolpho (1794). Date unknown for this Penguin paperback.
The ever-enigmatic Thomas Ligotti (1953), whose exquisitely weird short fiction was first collected in Song of a Dead Dreamer back in 1985 by Silver Scarab Press.
And Philip Nutman (1963-2013), journalist and author. His "Full Throttle" was a terrific entry in 1990's Splatterpunks.
