I really liked this story. It wasn't so much a horror as a type of dark fantasy/weird fiction/awe fiction. This book therefore isn't meant to frighten you only, but to inspire within you a sense of awe: of terror and of wonder at the same time. Blackwood ingeniously interweaves the two as you adopt the wife's or the husband's view point.
It's relatively short so give it a shot.
Really really good story of the creepy and awe-invoking sort. Recommended!
Highly recommended for all people who believe passionately in the equality of all human beings.
