My name is Renée. I am fifty-four years old. For twenty-seven years I have been the concierge at number 7, rue de Grenelle, a fine hôtel particulier with a courtyard and private gardens, divided into eight luxury apartments, all of which are inhabited, all of which are immense. I am a widow, I am short, ugly, and plump, I have bunions on my feet and, if I am to credit certain early mornings of self-inflicted disgust, the breath of a mammoth.
