In a Glass Darkly

Though carefully educated in medicine and surgery, I have never practised either. The study of each continues, nevertheless, to interest me profoundly. Neither idleness nor caprice caused my secession from the honourable calling which I had just entered. The cause was a very trifling scratch inflicted by a dissecting knife. This trifle cost me the loss of two fingers, amputated promptly, and the more painful loss of my health, for I have never been quite well since, and have seldom been twelve months together in the same place.

The curious case which I am about to place before you, is referred to, very pointedly, and more than once, in the extraordinary Essay upon the drugs of the Dark and the Middle Ages, from the pen of Doctor Hesselius.

In a Glass Darkly (1872), a collection of five short stories in the horror and mystery genres, presented as the posthumous papers of the occult detective Dr Hesselius.
