Best known of the five long tales of Sheridan Le Fanu which make up In a Glass Darkly is 'Carmilla'. The tale is a covert account of lesbianism, lusciously filmed with Ingrid Pitt and Kate O'Mara under the title The Vampire Lovers. Even so exotic a collection as In a Glass Darkly, with its German-writing exegete-behind-the-narrator and its continental locations, includes a sharp delineation of Georgian Dublin in The Familiar. 'German Ghosts and Ghost Seers' is likely one of Le Fanu's earliest sources for the doctrines of Emanuel Swedenborg. The ghostly Ferris must be treated as an influence upon the author of Uncle Silas and In a Glass Darkly. The stories of In a Glass Darkly arise, in several ways, from Dr Martin Hesselius's archive, and the variety of narrative-perspectives adopted in turn complicates the much-mediated relation between reader and character.
