." . . all existing lamps are paled by the rising of a fresh luminary order -- Mrs. Ann Radcliffe (1764-1823), whose famous novels made terror and suspense a fashion, and who set new and higher standards in the domain of macabre and fear-inspiring atmosphere despite a provoking custom of destroying her own phantoms at the last through labored mechanical explanations. To the familiar Gothic trappings of her predecessors Mrs. Radcliffe added a genuine sense of the unearthly in scene and incident which closely approached genius; every touch of setting and action contributing artistically to the impression of illimitable frightfulness which she wished to convey. A few sinister details like a track of blood on castle stairs, a groan from a distant vault, or a weird song in a nocturnal forest can with her conjure up the most powerful images of imminent horror; surpassing by far the extravagant and toilsome elaborations of others. Nor are these images in themselves any the less potent because they are explained away before the end of the novel. Mrs. Radcliffe's visual imagination was very strong, and appears as much in her delightful landscape touches -- always in broad, glamorously pictorial outline, and never in close detail -- as in her weird phantasies." -- H. P. Lovecraft, "Supernatural Horror In Literature"
