Police Judiciaire

Police Judiciaire is the French judicial police force whose investigators pursue the murder of Emil Florian and the abduction of Agnès Dantier and her father, Vincent. Its methods are practical and evidentiary: officers combine witness accounts, surveillance footage, timing, and spatial reconstruction to identify what happened. But the investigation also turns inward. The perpetrator’s plan is meant not only to take revenge on Agnès’s father, but to discredit the force for what its predecessors did—and failed to do—during the war.

Identity and Institutional Setting

Police Judiciaire operates as the investigative institution at the story’s centre. In its formal public role, it works alongside the examining magistrate and public prosecutor, while police commanders coordinate the response to major cases. At a briefing, Agnès welcomes the magistrate Albert Reboux and prosecutor Jules Frènes as representatives of the Palais de Justice, as well as Frédéric Anselme, chief of the GIPN. The scene places criminal investigation within a wider system of public authority, rather than presenting the police as acting alone.

The force’s responsibilities are shown at street level as well as in official meetings. Lieutenant Alejo Busquet identifies himself as a Police Judiciaire officer when he visits Marie Lacroix to interview her about the emergency call she made from Rue Verbier. That call had reported a Muslim killed during a prayer service, but the anonymous caller supplied no further account of how the man died. Because the call was made free of charge, without a card, investigators could not trace it directly; they would need the caller to come forward or be identified by other means.

Investigation and Evidence

The first investigation demonstrates how a crime scene can be both rich in possible evidence and difficult to manage. Rue Verbier is overlooked by at least fifty apartment balconies and many more windows; two cameras in a car park may also have recorded something. A shot from a window could have struck a stationary target, and a silenced rifle could have made the sound difficult to distinguish from an ordinary noise. Yet a large number of potential witnesses creates its own logistical problem. Roland Granot, the second-in-command and the officer best suited to triage them, is on leave.

Surveillance does not immediately supply a complete account. The camera trained on the marketplace does not cover the area outside the prayer room, and investigators initially see only part of the relevant sequence. Lartigue identifies footage of the old woman with a trolley as a before-the-incident image, promising to compare it with footage from another camera. The images must be read alongside testimony rather than treated as a self-sufficient record.

Marie Lacroix’s account later provides a crucial timeline. From a third-floor balcony opposite the Basilique, she saw Emil Florian join the prayer meeting, saw the woman later identified as Corinne Delage strike him with her shopping trolley, and watched him bend forward as if praying without getting up again. She also saw Florian arrive before the available CCTV footage began. That earlier movement helps investigators reconstruct his route: Florian had seen Armani Tardelli on Jean Médecin, concealed himself behind a Colonne Morris, and then ran when Armani entered a boutique on Rue Verbier. A small crowd watching a living-statue performer helped screen his movement. The sequence shows why a gap in recorded coverage need not mean there is no recoverable evidence: a witness’s view can supply the missing beginning.

The same attention to the limits and construction of surveillance becomes central to the later abduction inquiry. Investigators review Camera One from Agnès’s arrival in a Citroën until she fails to reappear around the corner. They mark the exact times of several image blips, since the kidnappers acted during that interval. Darac rejects explanations involving a camera jammer or a repeated time sequence: the displayed time tags remain continuous. He proposes instead that, on Thursday evening, a man photographed the camera’s field of view from precisely its vantage point, then later placed the photograph in front of the lens. The camera autofocus could not sharpen the image completely because the photograph was too close, and its framing differed slightly from the live scene. The simple deception was enough to obscure the abduction without altering the timestamp.

People, Procedure, and Public Trust

The force’s investigations require officers to deal with people who are not merely sources of information but also vulnerable to institutional classifications. When Darac tells Mansoor Narooq that the police know he is staying in the country illegally, Mansoor’s expression collapses. Darac does not take satisfaction in exposing his status; he wonders what it would mean to be moved around the world, unwanted except in the place where one was most vulnerable. Mansoor answers by invoking the annual deportation quota of twenty-five thousand and treating his own impending removal as one more subtraction. The encounter complicates the force’s authority: the investigation can identify a legal violation, but the act of classification carries a human cost that Darac recognizes.

Other moments expose the difference between investigative purpose and prejudice. Manou Esquebel tries to provoke Darac with a sexual proposition and a crude attempt to redirect the encounter; Darac declines, adding that he is neither gay nor a homophobe and will not provide a lawyer with grounds to allege an assault. The exchange is evidence of Manou’s tactic and Darac’s response, not a general statement about police conduct. It shows an officer resisting both provocation and the possibility that force might compromise the case.

The institution also encounters the history that gives the present investigation its larger stakes. Agnès explains to two young visitors that, in August 1942, Caserne Auvare was used to detain Jews rounded up by local police; more than five hundred people were deported to a holding camp near Paris and then to Auschwitz. Her account establishes that local policing has a wartime history of direct participation in persecution. In a different conversation, Darac invokes the separation of church and state to argue that citizens are not required to observe, believe in, or show respect for the Catholic faith. The juxtaposition of secular civic principle, minority religious practice, and historical police conduct places the force within ongoing conflicts over belonging and state power.

The Case Against the Force

The abductions and the threat attached to them are ultimately revealed as a plan directed at Police Judiciaire as an institution. Agnès reasons that Jarret’s first objective was revenge on her father. A second was to discredit the force as punishment for what its predecessors had done—and failed to do—during the war. If Agnès and her father were murdered after officials had received a warning, the public could blame the investigators for having ignored it. The scheme therefore turns the appearance of police failure into part of the crime’s intended effect.

The threat had to be alarming enough to damage the force if the murders occurred, but not so credible that Paris would commit overwhelming resources to stopping it. Extensive stop-and-search operations or increased surveillance could have obstructed the kidnappers and undermined Jarret’s first objective. Agnès sees this as a calculated balance: the threat was designed to create a public accusation without triggering the response that might prevent the abductions.

A further objective was to direct suspicion toward Muslims through the slogan Just Cause. The label would make the kidnappings look like the work of a terrorist organization and draw investigators away from the personal motive. Agnès identifies the strategy as an exploitation of race and bloodline, and concludes that the inability to move beyond those categories is among the saddest dimensions of the plot. The force’s struggle is consequently not only to solve crimes, but to resist the false explanation designed to exploit public prejudice.

Consequences and Significance

At the climax of the rescue, Darac discovers water seeping from beneath the lock-up’s roller door after a man identified as Monsieur Flaubert recognizes Astrid’s flyer. Regulations require him to call for backup and wait, but he remembers Astrid’s thirty seconds, drives away to gain space, and crashes his Peugeot through the door. Inside, he sees a hose running from the van’s tailpipe and understands that he must act immediately to disconnect it and locate Jarret. The moment presents procedure and urgency in direct tension: the institutional response has rules, but the evidence before Darac makes delay dangerous.

The completed case leaves Police Judiciaire exposed to a double judgment. The force must be capable of careful, technically informed investigation in the present, while acknowledging that its institutional predecessors were implicated in wartime persecution. Jarret’s attempt to turn that history into a weapon does not erase the history; nor does it make the present investigators responsible for every earlier act. The novel’s account of Police Judiciaire therefore binds operational competence to public trust and historical accountability, making the investigation a test of whether the institution can distinguish evidence from manipulation without denying the past it is being made to answer for.
