I'm reading a short story called "Tomorrow's Dead" by David Dean. He's a writer from Georgia now living in New Jersey, and his protagonist, who also lives in New Jersey, goes back to his home town of Columbus, GA. He has a conversation with the police chief, who gets down to business like this:
"So then, what is it we can do for you?" he asked in the gently tumbled grammar of the Piedmont.I have no idea why that question is being singled out as odd in any way, let alone as "gently tumbled" (whatever that is supposed to mean). Is this just because I grew up in Tennessee? Nowhere near the Piedmont, of course, but ... No. It sounds perfectly standard to me.
