This seems like an interesting mix of quirky, camp, funny, sharp, and dark. The main character is quite entertaining and odd. The characters feel 3D. It's refreshing to see an elderly protagonist that isn't reduced to a stereotype. I don't know what the scam is, but it'll have to be a good one for this MC to get fooled. I'd love to see her at the center of some black humor and go on ridiculous adventures to dole out some just deserts. Hope it stays a bit camp. Great dialogue so far.
