Identity

Chantal and Jean-Marc are an unmarried couple living together in Paris. She works at an advertising agency; he abandoned medical studies after three years and never found a replacement vocation. The novel traces the quiet unraveling and repair of their relationship as misunderstandings and anxieties about identity, aging, and love spiral into a crisis that blurs the boundary between reality and dream.

Chantal arrives alone at a hotel on the Normandy coast; Jean-Marc will join her the next day. At dinner she overhears waitresses discussing Lost to Sight, a television program about people who have vanished without a trace. She imagines losing Jean-Marc this way and being condemned to wait indefinitely. That night a dream populated by figures from her past, her dead mother, her ex-husband, his domineering sister, nullifies the present she cherishes by replacing Jean-Marc with a life she abandoned long ago.

Meanwhile, Jean-Marc visits F., a gravely ill high school friend in Brussels. F. recalls that the teenage Jean-Marc once declared the sight of an eyelid blinking over a cornea filled him with disgust. Jean-Marc has no memory of the remark and reflects that modern friendship serves only as a mirror for one's past self. After leaving the hospital, he feels an overwhelming need to be with Chantal.

The next day on the shore, Chantal watches men pushing strollers and formulates a melancholy thought: She lives in a world where men will never turn to look at her again. On the beach, Jean-Marc spots a distant figure he takes for Chantal and panics when a speeding sailcar heads toward her. The woman turns out to be a stranger, and Jean-Marc is shaken by the realization that he cannot reliably distinguish the person he loves from anyone else.

Back at the hotel, when Jean-Marc presses Chantal to explain her mood, she says men no longer turn to look at her. She intends the remark as light, but it comes out bitter, and a powerful wave of heat engulfs her, one of the fierce hot flashes she refuses to name. Jean-Marc is shaken: Her sadness about male attention feels like an erasure of his devotion. When he tries to embrace her, she pushes him away, afraid her damp body will betray the aging she cannot bring herself to discuss.

Essential backstory explains the weight of this moment. Chantal's son died at age five. When her sister-in-law and husband urged her to have another child so she would forget, Chantal decided to leave. She felt the extended family was trying to absorb her, treating her body as communal property. She chose advertising over teaching because it could fund her independence, waited years before meeting Jean-Marc, then asked for a divorce, bought an apartment, and moved in with him without marrying.

Back in Paris, Chantal finds an unstamped letter in her mailbox praising her beauty. She hides it beneath her brassieres in the wardrobe. A second letter arrives, signed "C.D.B.," describing her movements on a specific Saturday. More letters follow, growing bolder; the most recent imagines flinging a crimson cardinal's mantle over her naked body. Inspired, Chantal buys a red nightgown and wears it during lovemaking with Jean-Marc, sensing a third presence watching them. She tries to identify the writer, first suspecting a young man at a corner bistro, then a dignified beggar on their street, but each candidate proves wrong.

The narrative reveals the truth: Jean-Marc is the author of the letters, writing under the coded signature C.D.B. The initials stand for Cyrano de Bergerac, the literary figure famous for composing eloquent love letters on another's behalf. After Chantal's remark that men no longer look at her, Jean-Marc wrote the first letter to restore her confidence. When she hid it instead of showing him, he kept writing, describing her body part by part. He was gratified to see her dress with greater care but stung that she followed another man's aesthetic suggestions rather than his. After discovering the letters hidden beneath her brassieres, his jealousy deepens: Her secrecy seems to protect the possibility of a future adventure. Yet love prevails, and he writes one final letter announcing the correspondent's departure for London, the city he and Chantal associate with Britannicus, a lecherous older Englishman who once courted her.

Chantal conducts her own investigation. She visits a handwriting analysis office, where an assistant confirms that C.D.B.'s script matches Jean-Marc's. She rereads a letter describing her trip to the dry cleaner and realizes the details could only have been observed by Jean-Marc, who was inside the shop with her. She concludes he is spying on her, seeking a pretext to leave because she has grown old.

Crisis erupts when Chantal's former sister-in-law arrives unannounced with three children who ransack the bedroom, flinging open the wardrobe and scattering brassieres and hidden letters across the floor. Chantal orders the visitors out and declares no one has the right to rummage in her things, a statement aimed more at Jean-Marc than at the intruders. Alone with him, she reads the final letter in front of him, showing she knows he is the author. They exchange bitter accusations: She calls him a spy; he accuses her of hiding in conformism. That night, for the first time, they eat without speaking.

The next morning Chantal packs a valise and announces she is going to London. Jean-Marc places his keys on the foyer table as a sign he will not return and follows her to the Gare du Nord station. There, Chantal is surprised by agency colleagues heading to a London conference and boards the train with them. She listens to her boss, Leroy, argue that the meaning of life is procreation and nothing more. Chantal finds herself agreeing that love as passionate attachment to one person either does not exist or ought not to. As the train enters the Channel Tunnel, the words "lost to sight" return to her, and the journey toward disappearance feels gentle, even joyful. Jean-Marc, who has boarded the same train, watches her from behind, noting a lively persona he does not recognize.

At London's station, chaos erupts. Jean-Marc spots Chantal but is seized by a policeman as he struggles through a crowd. By the time he is freed, she has vanished. Leroy refuses to reveal her hotel. Jean-Marc wanders the city with barely enough money for a return ticket and sits on a bench facing a row of white houses.

The narrative shifts into a dreamlike register. Jean-Marc storms into a house with red curtains, imagining an orgy. Chantal finds herself among naked bodies, repelled yet aroused, and flees through corridors. She takes refuge in a broom closet with a dog curled on rags and asks the dog which man it used to be, sensing an enigmatic greeting from some inaccessible past, a trace of a fantasy of Jean-Marc's about orgiasts turning into animals. She then finds herself in a large salon where a septuagenarian in a white robe calls her "Anne." She insists that is not her name but cannot remember her real name. She strains to recall the man who loved her; fragments surface, a garden, a dead child. She hears doors being nailed shut and, desperate, emits a long, inarticulate cry.

Then Jean-Marc is clasping Chantal's shuddering body, telling her to wake up. The narrator intervenes, asking who dreamed the story and at what point reality turned into reverie. Was it when the train entered the tunnel, that morning, when the first letter was sent, or was the letter itself only imagined? The question goes unanswered.

In the final scene, Chantal and Jean-Marc lie together by bedside lamplight. She tells him she will never let him out of her sight, afraid that even during the instant her eyelid blinks, something could slip into his place. She refuses his kiss, wanting only to look at him. She will leave the lamp on all night, every night: a vigil against the disappearance of the beloved into the dark interval of an unseen moment.
