On a rain-dark September night near Hampstead, a young medical student makes a routine walk along Millfield Lane and stumbles over what seems at first to be a stump in the shadows. It is the foot of a dead man, and the discovery hurls him into a mystery that feels at once clinical, eerie, and dangerous. When he returns with a policeman, the body has vanished, leaving only wet footprints, a deserted lane, and mounting suspicion that he has seen something impossible. By daylight, he finds fresh clues: a bloodstain on the fence, signs that the body may have been lifted into the woods, and a curious gold trinket engraved with cryptic letters. Tracks lead toward Ken Wood and a hidden estate, hinting at a secretive, possibly religious connection, but the police remain unconvinced. As autumn settles over Hampstead, the doctor resumes his rounds, yet the mystery continues to haunt him. He also becomes drawn to Sylvia Vyne, a charming young woman whose company brings a welcome lightness—until they notice a foreign-looking man shadowing them in a gallery. His left-handed writing, odd eyes, and intense attention to Sylvia's crucifix suggest a hidden identity, and the doctor realizes that the vanished corpse and the watcher in the gallery may be tied to the same unsettling secret.
