Joseph Thomas Sheridan Le Fanu was an Irish writer of Gothic tales and mystery novels. He was the premier ghost story writer of the nineteenth century and had a seminal influence on the development of this genre in the Victorian era. He was a meticulous craftsman, with a penchant for frequently reworking plots and ideas from his earlier writing in subsequent pieces of writing. He specialised in tone and effect rather than “shock horror”, often following a mystery format. (source: Wikipedia)
