Problem is, I'm not cooking a turkey.
I figured that it's one of the neighbors slow roasting a turkey overnight, and through some fluke of a drafty old house, the smell is invading. It seems a little weird at 2:00 in the morning, but whatever.
Problem is that I just let Sadie outside to pee, and there is no smell of roast turkey outside.
It seems to be coming from inside the house.
Apparently, I have a ghost, and it likes to cook for the holidays.
