May I knock on the door at exactly 9am, and she opens it a few seconds later. Her clothes are all wispy layers of black and she has bright red hair clipped up on top of her head and lipstick the same colour as her hair. She is far more beautiful than I had imagined when we talked on the phone, but also far more anxious – her hands flutter to and from her face as she shows me around, and she apologises constantly for the mess, even though the house is spotless.
