The Massé household and their nanny Louise
In Paris's 10th arrondissement, lawyer Myriam Massé and her husband Paul, a music producer, hire Louise, a meticulous, indebted white Frenchwoman, to care for their children Mila and Adam so Myriam can return to work. Louise becomes indispensable, cooking, cleaning and joining the family on holiday in Greece, while her own life collapses into eviction and poverty. The novel opens with 'The baby is dead' after Louise has killed both children, then goes back to the hiring and runs forward to that moment.
