Marius tracks and loses the Leblanc father and daughter

Marius’s effort to follow M. Leblanc and his daughter transforms romantic curiosity into a vigil, then into a loss that governs his search for them. He learns where they live and repeatedly watches for their return, but surveillance cannot secure the connection he longs for: the pair disappear, leaving him to wait through successive days and nights with no certainty of where they have gone.

Finding the Address

After discovering the young woman in the Luxembourg Gardens, Marius follows her and the older man he calls M. Leblanc. He comes away pleased with what he has learned: he believes the daughter is named Ursule, that she is the child of a rentier, and that they live on the third floor of a house on Rue de l’Ouest. The details seem to turn an elusive encounter into a knowable destination.

The next day, Marius follows them from the Gardens to the house. At the entrance, M. Leblanc lets his daughter go ahead, then pauses before crossing the threshold and looks directly at Marius. The look makes the pursuit briefly visible to the person being followed. Yet Marius continues to treat the house as a place from which he might maintain contact: it gives his attention a fixed point even when he has no invitation or assurance that the pair will appear again.

A Vigil on Rue de l’Ouest

The following day, M. Leblanc and his daughter do not come to the Gardens. Marius waits there in vain, then goes to Rue de l’Ouest after nightfall. A light in the third-floor windows keeps him beneath the house until it goes out. When they are again absent from the Gardens, he returns to his nighttime watch. His dinner becomes uncertain, and the narration presents love as sustaining him through the vigil even as ordinary life gives way to waiting.

For eight days, the two do not reappear in the Gardens. Marius does not dare watch the entrance during daylight; instead, he goes at night to contemplate the reddish light behind the windows. Passing shadows stir his hopes, but reveal nothing definite. The watch narrows into an attention to signs: a lit window, a moving shadow, the possible presence of the people he is seeking.

On the eighth night, no light appears. Marius waits first until ten, then until midnight, and finally until one in the morning. No one enters the house, and the third-floor windows remain dark. He leaves in a gloomy state. The repeated extension of his vigil makes the absence more than a missed meeting: every additional hour postpones the answer he hopes to find while making the possibility of their departure harder to ignore.

The Disappearance

The next day, Marius returns to the Gardens, expecting not to find them, and later goes back to Rue de l’Ouest. The windows are dark, the shutters closed, and there is no sign of life on the third floor. He enters through the main doorway and asks the porter about the tenant upstairs. The answer is that the man has moved away. Marius falters and asks when it happened, but the decisive fact is already clear: the address that had organized his pursuit no longer leads to M. Leblanc or his daughter.

The porter recognizes him and teasingly asks whether he is, after all, a spy. The remark gives a name to the awkwardness already present in M. Leblanc’s fixed look: Marius’s devotion has taken the form of watching people who have not asked to be watched. But the question does not restore the lost trail. His careful attention has established where the pair lived, not where they have gone, and he leaves without a new means of reaching them.

What the Lost Trail Opens

Several months pass without Marius finding any trace of the young woman. The disappearance therefore does not resolve his attachment; it suspends it. When he eventually sees her again, it is in the miserable apartment of his neighbor, Thénardier, where she and her father have come to give Marius sixty francs out of pity. The return of the pair overturns the apparent separation, but does not simply restore the earlier pattern: Marius now asks Thénardier’s eldest daughter to obtain the young woman’s address, promising her whatever she wants in exchange.

The renewed search soon intersects with a planned trap. Marius overhears Thénardier and his wife discussing an attempt to blackmail M. Leblanc, whom they say they have recognized. He decides to alert the police, and Inspector Javert takes charge. Marius then learns that the man planning the attack is Thénardier, the same man he believes saved his father at Waterloo. His attempt to protect M. Leblanc collides with his sense of duty to his father’s memory; before he can decide what to do, the police arrest the bandits, while M. Leblanc disappears before Inspector Javert arrives. The original loss thus leads into a more dangerous pursuit, where finding the people he seeks brings Marius face to face with a conflict his surveillance alone cannot settle.
