Lullaby

Leïla Slimani’s Lullaby (published as The Perfect Nanny in the US and originally as Chanson douce in France) opens with one of the most chilling lines in contemporary literature: “The baby is dead.” In the very first paragraph, we learn that the nanny has killed two children. By revealing the horrific conclusion immediately, Slimani transforms the novel from a “whodunit” into a terrifying “why-dunnit,” forcing the reader to painstakingly examine the social and psychological threads that led to this tragedy. There is no mystery about the perpetrator; the mystery is the society that produced her. What follows is not just a thriller, but a ruthless dissection of class, race, gender, and the dangerous intimacy of domestic labor in contemporary Western society.

The story centers on Paul and Myriam, a bourgeois Parisian couple navigating the difficult transition from young parenthood to continued professional ambition. Myriam, a French-Moroccan woman who gave up her law career to raise their two young children, feels herself disappearing into the identity of “mother.” She loves her children, but she is also suffocating, mourning the brilliant career she abandoned. When she is offered a chance to return to work, she seizes it, and the couple hires Louise, a middle-aged white French nanny, to care for Mila and Adam. Louise initially presents herself as a miracle worker. She is quiet, polite, and unbelievably efficient. She doesn’t just care for the children; she scrubs the apartment until it gleams, cooks elaborate gourmet meals, and mends clothes with expert skill. She makes herself utterly indispensable, creating a “perfect” domestic sphere that allows the parents to pursue their professional and social lives without guilt. The parents, grateful and relieved, fool themselves into thinking they have accepted her into the family, taking her on vacation and bragging about her to friends as if she were a magical discovery.

However, Slimani masterfully exposes the rot beneath this veneer of perfection. The relationship between the couple and the nanny is defined by a deeply unequal power dynamic, despite—or perhaps because of—Louise being white and French. In France, where discussions of race often focus on immigrants and minorities, the hiring of a white nanny by a mixed-race couple inverts and complicates expected narratives. Yet Louise is still a servant in the truest sense—silent, invisible, and utterly dependent. She is expected to be grateful, to perform happiness, to have no needs of her own that might inconvenience her employers. The apartment, which she maintains with such obsessive care, is a stage where she performs perfection but where she has no real power, no stake, no future. She lives entirely for and through this family, and they, in their liberal self-congratulation, fail to see how precarious and ultimately dangerous that dependence is.

As the narrative peels back the layers of Louise’s life, we see the crushing weight of her circumstances. She is a widow, drowning in debt left by her deadbeat husband, chased by tax collectors and landlords, estranged from her adult daughter. Her small, filthy apartment is a stark contrast to the bright, clean Parisian flat she tends so lovingly. She is haunted by a past of abuse, neglect, and failure. The Massé family’s home becomes her only refuge, a fantasy world she clings to with desperate, suffocating intensity. When she is there, cooking and cleaning and caring for the children, she can almost believe she belongs. When she is sent home, alone to her empty life, the abyss opens beneath her feet.

The novel brilliantly critiques the “care economy” and the invisibility of the women who sustain it. In wealthy cities around the world, professional couples outsource the labor of child-rearing, house-cleaning, and emotional maintenance to an army of underpaid, often immigrant or working-class women. Myriam and Paul’s liberation—their ability to have careers, to go out to dinner, to take vacations—is built on Louise’s subjugation. They are often careless with her boundaries, keeping her late without asking, assuming her availability, underpaying her emotionally if not always financially, and ultimately discarding her needs when they become inconvenient. They congratulate themselves on treating her “like family” while never truly seeing her as an equal human being. The tension of the novel builds not through jump scares or dramatic confrontations, but through the accumulation of small humiliations and the claustrophobia of a relationship that is intimately physical—Louise bathes the children, puts them to bed, knows their bodies—yet rigidly hierarchical.

Slimani also interrogates the impossible demands placed on mothers. Myriam is caught between her desire to work and the guilt-inducing expectations that a “good mother” should be at home. She is judged for outsourcing her maternal duties even as she is implicitly encouraged by society to pursue professional success. This bind—be everything to your children, but also be a successful professional—is presented as unwinnable. Louise, in her terrifying perfection, becomes a mirror reflecting society’s demands back at mothers: you could be like this, if only you tried harder.

Louise’s unraveling is depicted not as a sudden break but as a slow “wobbling” of the mind, a silent scream of repressed rage and desperation. She becomes increasingly obsessed with the idea of keeping her place in the family, her identity now completely fused with her role as nanny. She convinces herself that if Myriam were to have another baby, it would secure her position forever. When this fantasy is blocked—when she begins to sense that her services may no longer be needed—her love for the children curdles into a monstrous, possessive rage. The murder is not an act of madness in the sense of being random or inexplicable; it is the logical, horrifying terminus of a system that dehumanizes care workers and isolates them in intimate spaces with those they serve.

Lullaby is a work exploring the “banality of evil,” showing how the monstrous can emerge from the mundane stresses of modern parenting, the isolation of urban life, and the deep, unbridgeable chasms of class inequality. It is a lullaby that turns into a nightmare, a soft song that ends in a scream. Slimani refuses to make Louise a simple monster or a simple victim; she is both, a product of a society that demands invisible labor and offers no safety net when those laborers fall. The novel is a warning, and a diagnosis, exposing the terrors that lurk not in far-off places but in the very heart of the bourgeois home, in the nursery, in the kitchen, in the quiet hours when no one is watching.
