Summary

Gibert secures a terrorism‑provision warrant for the parking garage’s CCTV footage after polite requests fail. He leaves intimidating officers to guard the server and the access doors. Once the warrant is finalized, the garage’s lawyer forces compliance. Gibert drives from Levallois‑Perret to Brunelle’s DGSI office, joking about Paris traffic. At DGSI, Brunelle introduces him to digital forensics specialist Mohammed “MoMo” Motii. They load the garage’s CCTV onto MoMo’s system. Brunelle directs MoMo to first filter out hatchbacks, then focus on cars that arrived Sunday and left Monday after the murder. Using AI software, MoMo matches drivers to vehicles, but gait recognition does not find the suspect. MoMo then checks Métro‑tunnel footage and spots the suspect exiting a fake airshaft door. The AI pinpoints a chalk‑colored Peugeot sedan as the escape vehicle. The driver avoided cameras; the license plate shows the car was stolen Sunday morning and later found torched in Seine‑Saint‑Denis with a special accelerant, making evidence recovery unlikely. Gibert doubts witnesses will cooperate, but MoMo insists he can talk to people from that district because he is from there.

Key Events

  • Gibert obtains a warrant under a terrorism emergency provision for the parking garage’s CCTV footage.
  • Gibert and Brunelle decide to analyze the footage at DGSI because her equipment is better.
  • MoMo uses AI to filter vehicles: removes hatchbacks, then isolates cars parked Sunday and leaving Monday.
  • Gait‑recognition AI finds no match for the suspect.
  • MoMo reviews Métro‑tunnel cameras and catches the suspect leaving a fake airshaft door.
  • The AI identifies a stolen, chalk‑colored Peugeot as the likely escape vehicle.
  • The Peugeot is later found torched in Seine‑Saint‑Denis; firefighters note a special accelerant.
  • MoMo challenges Gibert’s claim that locals won’t talk, stating he can engage witnesses because he grew up there.

Character Development

  • Inspector Gibert: Demonstrates procedural persistence (securing warrant) and an awareness of antipolice sentiment in France. His joke about DGSI’s fancy environment reveals a blue‑collar cop’s perspective. He initially dismisses the possibility of cooperation in Seine‑Saint‑Denis.
  • Brunelle: Efficient and tactical, she guides the digital investigation, quickly grasping the AI’s capabilities. She authorizes the use of “training simulations” that would be inadmissible in court, showing a willingness to bend rules for results.
  • MoMo (Mohammed Motii): A new asset introduced this chapter. He is confident, skilled with AI, and proud of his origins. His remark that police don’t know how to talk to people from Seine‑Saint‑Denis hints at a cultural bridge he can provide.

Themes, Symbols, or Motifs

  • Trust vs. Surveillance: The chapter contrasts the public’s distrust of police (antipolice sentiment, reluctance to cooperate) with the police’s increasing reliance on surveillance technology (CCTV, AI facial/gait recognition).
  • Professionalism: The killer’s team is described as “professionals” who know how to avoid cameras and destroy evidence (stolen car torched with accelerant). This motif elevates the antagonists beyond ordinary criminals.
  • Class and Geography: The contrast between the sleek DGSI building (Levallois‑Perret, an affluent suburb) and the troubled district of Seine‑Saint‑Denis (MoMo’s home) underscores socioeconomic divides that affect police‑community relations.

Why This Chapter Matters

This chapter advances the investigation by tying the killer’s escape to a specific vehicle and revealing the existence of a professional support network. It also introduces MoMo, a character who brings a vital skill set (AI forensics) and local knowledge that traditional cops lack. The use of computer‑vision AI – though technically inadmissible – speeds up the hunt and forces characters to confront the gap between formal legality and operational effectiveness. The destruction of the Peugeot eliminates forensic evidence, raising the stakes for the next step: finding a human witness in a community where police have little credibility.

Study Questions and Answers

1. Why does Gibert leave intimidating officers at the garage before the warrant is signed?
Answer: He fears that employees with antipolice sentiment might deliberately destroy CCTV footage or tamper with the evidence doors. By posting his toughest officers, he hopes to prevent any “accidents” while the warrant is being processed.

2. What two steps does Brunelle take to narrow down the suspect vehicle using MoMo’s AI?
Answer: First, she eliminates hatchbacks because a trunk is needed to hide a person. Second, she limits the search to cars that arrived on Sunday (the day of the murder) and left on Monday morning, reducing the number of vehicles to four.

3. Why does MoMo believe he can succeed where Gibert expects failure in finding witnesses?
Answer: MoMo explains that the problem is not that residents of Seine‑Saint‑Denis refuse to talk—it’s that the police do not know how to communicate respectfully with them. Because MoMo grew up there, he understands the local culture and can approach potential witnesses effectively.
