Doppelganger Country

I am rereading COAL MINER'S DAUGHTER by Loretta Lynn before teaching it to some graduate students, or as they are sometimes called by the more whimsical and capricious among us, "grad students." Last time I mentioned the book, I told you about a UFO in it. Well, get this! I guess I forgot it also has a doppelganger in it, or as I like to call it, a doppelgänger. Thank goodness for the "blog" someone on the "internet" had the foresight to produce an illustration of the very alive Ms. Lynn looking like a ghost for no reason! Our scene begins as young Loretta is playing a Halloween prank: "We were rubbing soap on the windows of Tillie Dollarhide, who lived just up the holler. I could see her working in the kitchen. Suddenly I looked down in the yard and saw that same woman walking by some rocks in her garden."
