Another Dinesen story of ruined happiness

Isak Dinesen's story The Ring, in her final collection, Anecdotes of Destiny, is yet another example of her strange cruelty and misanthropy  the story at the start has all the telltales of a sweet fable about enduring Loren - and yet...if you've ever read Dinesen - which presumably you have as this is the last story in the collection - you know things will not go well and the story will take a turn toward dark matter.  In short: a young recently married couple are enjoying the first days of their life together in a cottage in the countryside where the very competent husband is beginning to earn a living running a small sheep farm. The two stroll through a verdant landscape and arrive at the sheep pen to learn that two of the sheep are ill and that a thief has stolen sheep and bled them to death over the past few nights. Oh? As the husband discusses these ominous matters w a hireling the young wife heads off for a stroll  oh? And for no possible reason she leaves the trail and heads into a glade where she of course runs into the sheep thief - bearing a knife. Oddly she tosses a handkerchief and her wedding ring onto the ground - and the thief kicks the ring aside. She returns to her has and. He can see that she's upset and she tells him she has lost her wedding ring. He's surprisingly blasé and says don't worry we can replace it.  I but its obvious they cannot replace the ring and that their marriage is ruined and that somehow she has been possessed by an evil force. So I guess this is a fable of some sort, but what makes ID dwell as she does on such ruined happiness and such tortured lives? There are other "dark" writers of course, many of them genre writers (Poe and Lovecrsft come to mind) but few if any who write so persistneltly about the destruction of innocence and in such a genre-defiant manner.  This story is perhaps the conscious counterweight to de Maupassant's Necklace story - the mysterious and unfounded (not a hint of foreshadowing to the wife's reckless behavior) actions and blind, destructive fate.
