The housemaid, "Welcome to the family," says Nina Winchester as I shake her elegant, manicured hand. I smile politely and look around the marble hallway. The work here is my last chance to start anew. I can pretend to be who I want. But I will soon learn that the secrets of the Winchesters are far more dangerous than my own... Every day I clean the beautiful house of the Winchesters from top to bottom. I pick up her daughter from school. And I cook a delicious meal for the whole family before eating alone in my tiny room on the top floor. I try to ignore how Nina makes a mess only to watch me clean up. How she tells strange lies about her own daughter. And how her husband, Andrew, seems to be more broken by the day. But when I look into Andrew's pretty brown eyes that are so full of pain, I can hardly imagine what it would be like to lead Nina's life. The walk-in wardrobe, the chic car, the perfect husband. The secret of the housemaid "Don't go to the guest room." A shadow falls on Douglas Garrick's face as he touches the door with his fingertips. "My wife... she is very sick." As he continues to show me her incredible penthouse apartment, I have a terrible feeling because of the woman behind closed doors. But I can't risk losing that job - not if I want to keep my darkest secret … It's hard to find an employer who doesn't ask too many questions about my past. That's why I thank my lucky stars for miraculously giving me a job of cleaning their stunning penthouse overlooking the city and preparing chic meals in their gleaming kitchen. I can work here for a while and stay calm until I get what I want.
