Rue d’Hauteville is both a Paris address and a threshold between Louise’s isolated life and the household in which she becomes indispensable. The Massé family’s fifth-floor apartment stands on this street; Louise repeatedly travels to it, tends its rooms, and returns to it as her own pressures intensify. Its significance lies in the way familiar urban routines—walking to work, entering an apartment, cleaning a kitchen—gradually acquire the weight of foreboding.

Setting and the Massé Apartment

The Massé apartment is in a handsome building on Rue d’Hauteville, in Paris’s tenth arrondissement, where neighbors exchange warm greetings without knowing one another. It is the smallest apartment in the building. When their second child was born, Paul Massé and Myriam divided the living room with a partition; they sleep in a cramped room between the kitchen and a window facing the street. Myriam’s collected furniture, Berber rugs, and Japanese prints give the compact home a distinctly personal interior.

That domestic space is also the center of the family’s daily dependence on Louise. She records school and dance schedules, medical appointments, the children’s medicines, and even small purchases in a flower-covered notebook. She rearranges cupboards, puts lavender sachets among the coats, and keeps the apartment so orderly that accumulated dishes, laundry, and unopened mail disappear. The street’s apartment is thus not merely where the family lives: it is where the repeated work of producing their comfort becomes visible.

Louise’s Route and Arrival

Louise approaches the apartment through a long commute and often arrives early. On one morning she reaches the building with nearly an hour to spare, waits at the nearby Café Le Paradis, then enters and sits on a stair between floors rather than ringing before the agreed time. Paul finds her there as he comes down carrying his bicycle, a pink helmet on his head. Asked why she did not come in, she says she did not want to disturb anyone. The episode establishes a pattern of restraint and watchfulness at the building’s threshold.

Her commute becomes a repeated act of endurance. On Monday mornings she leaves before dawn, walks to the RER, changes at Auber, waits for the train, goes up Rue Lafayette, and then takes Rue d’Hauteville. The narration likens her to a soldier pressing on and to an injured animal that continues forward. The route gives the apartment a double meaning: it is the destination of her paid labor and the daily path into the family attachment that increasingly organizes her life.

Domestic Order and Unease

Louise’s work transforms the apartment. She prepares meals, manages the children’s routines, and continues cleaning even when Myriam tells her that she can leave. After the children come out of the bath and run into their mother’s arms, Louise scrubs the tub, folds towels, empties the washing machine, prepares the children’s beds, and begins dinner. When Myriam tries to take a saucepan from her, Louise holds on and gently urges her to rest and enjoy the children. Her competence makes her nearly invisible at the same time that the household comes to rely on her.

The kitchen later shows how an ordinary domestic space can become unsettling. One evening it appears cleaner than usual: the refrigerator door, cupboard handles, and extractor hood have been wiped, and the window is gleaming. On the small table where the children and their nanny eat sits a chicken carcass stripped of every trace of meat. Against the immaculate surfaces, the bare skeleton looks less like a meal’s remains than a disturbing presence. Rue d’Hauteville’s apartment holds both the reassuring evidence of Louise’s care and the objects through which that reassurance turns ominous.

Pressure, Return, and Aftermath

Louise’s daily relation to the neighborhood is not only a matter of work. A month before the tragedy, she tells Rose Grinberg that she is in financial trouble: her landlord is harassing her, debts have accumulated, and her bank account is overdrawn. She offers to work evenings or early mornings, cleaning or ironing. The disclosure connects the orderly apartment on Rue d’Hauteville to the economic precarity Louise carries beyond it, while Rose’s recollection later becomes part of the surrounding account of the events.

After Paul and Myriam leave for a holiday, Louise doubles back up Rue d’Hauteville and enters their apartment. She opens the shutters Myriam had closed, changes all the sheets, empties cupboards, cleans shelves, shakes out the old Berber rug Myriam refuses to replace, and vacuums. She then remains in the apartment for the week, living on the sofa, watching television, and eating from the refrigerator and pantry. The return turns a workplace into a temporary private refuge, though Louise still does not sleep in the couple’s bed.

As Louise’s distress deepens, the children’s repeated questions and demands become intolerable to her, and the apartment is where she spends the day with the television on while refusing to take them to the square. Later, Captain Dorval’s investigation reconstructs the morning of the crime through testimony and neighborhood inquiries, including accounts connected to the building and the nearby café. The same address that once signifies a carefully sustained family routine is consequently bound to the hidden strain beneath that routine and to the investigation that follows its rupture.
