The Turn of the Key - Ruth Ware

Okay, it´s prediction time:


"Rihannon, listen, I can promise you this - this is absolutely cast iron. I swear on - on my grave, I am never, ever going to sleep with your father."


It was on the tip of my tongue.

I am never, never going to sleep with your father because -




- he is also my father.
