“Welcome to the family,” Nina Winchester says as I shake her elegant, manicured hand. I smile politely, gazing around the marble hallway. Working here is my last chance to start fresh. I can pretend to be whoever I like. But I’ll soon learn that the Winchesters’ secrets are far more dangerous than my own.... Every day I clean the Winchesters’ beautiful house top to bottom. I collect their daughter from school. And I cook a delicious meal for the whole family before heading up to eat alone in my tiny room on the top floor.
