Foraging through old Fontana Great Ghost Stories paperbacks, I found this excellent story by Desmond MacCarthy - an author I know very little about, and who doesn't seem to have written many (any?) other notable ghost stories... but this is a superb one.
I hope you enjoy "Pargiton and Harby". Another "deep cut" horror story is coming soon, alongside some bona fide classics!
Stay tuned...
