It's hard to find an employer who doesn't ask too many questions about my past. So I thank my lucky stars that the Garricks miraculously give me a job, cleaning their stunning penthouse with views across the city and preparing fancy meals in their shiny kitchen.

I can work here for a while, stay quiet until I get what I want. It's almost perfect. But I still haven't met Mrs Garrick, or seen inside the guest bedroom. I'm sure I hear her crying. I notice spots of blood around the neck of her white nightgowns when I'm doing laundry. And one day I can't help but knock on the door. When it gently swings open, what I see inside changes everything.... That's when I make a promise. After all, I've done this before. I can protect Mrs. Garrick while keeping my own secrets locked up safe. Douglas Garrick has done wrong.

He is going to pay. It's simply a question of how far I'm willing to go.... An unbelievably twisty read that will have you glued to the pages late into the night.
