Dude buys a house out of town from the family of the old Greek immigrant who had it since like World War 2. “Oh, one thing, she said the spring down the bottom of the yard running to the creek is sacred. Never let us play in it. Funny the stuff from the old country, right?”
And he laughs and doesn’t think anything of it and then decides he can save on the water bill by plumbing it in to flush his toilet, and finds out that the old dear didn’t move continents alone… Hey, coulda been worse. She’s got another friend living out in the woods, makes hyper realistic stone sculptures in memory of local missing persons…
It’s easy to see why I never went anywhere with this, but good luck if you ever do try it! Though got a few other fics to do first, right?
