God I probably knew her Califrau.
I knew an alcoholic mother like that once. Was always wearing fur coats (quite literally fur coat and no knickers) even in the hottest of heatwaves, and had a sort of glazed look and askew make-up. And she would have a coca cola tin which was full of brandy or whisky or something. Once she hit one of the church helpers and declared that she'd done it for the priest, as he wasn't free to hit the woman himself, but as she slurred confidentially at me "he's wanted to give her a slap for years, but he can't because of holy orders and the bishop."
Happy days.
