The Perfect Nanny - Leila Slimani
From the very first sentence of this Prix Goncourt-winning psychological thriller, we know that this is no Mary Poppins tale. Neither is it a conventional thriller, as it delves deep into the prickly issues of class and gender that emerge when a busy, successful working Parisian couple hire a stranger to look after their children. When doll-like, self-assured, imperturbable Louise shows up for an interview, it is love at first sight for everyone. Myriam and Paul hire her, and thus begins a twisted relationship of dependence, resentment, jealousy, and obsession.
