A BEAUTIFUL WOMAN. A MEDICAL EXPERIMENT. THE HORRIFYING TRUTH OF WHAT LIES HIDDEN IN THE SOUL. _THE INMOST LIGHT_ is a deeply disturbing psychological horror story by ARTHUR MACHEN, exploring the esoteric terror of identity and the transference of consciousness. The tale is introduced through a group of friends discussing a baffling and tragic case: the mysterious deterioration and eventual death of Mrs. Lathom, the beautiful and refined wife of a prominent London doctor. Dr. Lathom, a respected scientist, becomes obsessed with a secret, revolutionary medical project that requires him to study HUMAN CONSCIOUSNESS. _THE INMOST LIGHT_ is a chilling masterpiece of body-horror and transcendental dread, a precursor to many modern stories of mind-switching and the fundamental terror of losing one's identity.
