Comment: It’s a bit unclear to what genre this story exactly belongs (unless one reads SF simply as Speculative Fiction).
The affair had occurred five years previously. The house was abandoned and perhaps inevitably there was talk of haunting. Jean explicitly corroborated these reports. The group had been jocular, skylarking, inviting ghosts to the feast: all ostensibly casual and careless, but all inwardly thrilling to the spooky look of the house, and the memory of the macabre killing. Jean had noticed a flickering of red light at the window of the living room. She had assumed it to be a reflection of the fire, then had looked again. There was no glass in the window. Others noticed; there were squeals and squeaks from the girls. All rose to their feet. Inside the living room, clearly visible, hung a body, twisting and writhing, clothed in flames. And from within came a series of agonized throat-wrenching sobs.
