What Happens in The French Detective: Full Plot Summary

The whole story of The French Detective (1975) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Two Rouen-based detectives, Commissioner Verjeat Lino Ventura and Inspector Lefèvre Patrick Dewaere, form an unlikely team. Verjeat is a weathered, street-smart veteran, while Lefèvre is a young, sharp-edged cynic who questions every rule. Their initial friction—snappy quips and mismatched styles—gradually softens into a wary partnership as they tackle a case that blends crime with political intrigue.

Their assignment is to take down a corrupt politician. During a heated election, a melee erupts between the supporters of two candidates. In the chaos, an opponent’s volunteer is murdered and a police officer is killed. The officer manages to warn colleagues that the killer is Portor Michel Peyrelon, a notorious thug whose notoriety looms over the campaign. Portor’s actions are tied to the broader political machine, since his brother is campaigning on behalf of the “law-and-order” candidate Lardatte Victor Lanoux. Verjeat believes the politician who hired the thugs bears guilt as well, and he pursues the case with a relentless, often stubborn focus that clashes with political pressure.

The chase is complicated by power and pride. Verjeat’s pursuit is impeded by Lardatte, a figure who wields influence and doesn’t hide his disdain for the detective. The tension spikes when Verjeat, during a tense moment of disarming a hostage—the dead volunteer’s father—finds himself publicly humiliated. The higher-ups announce a promotion and a transfer to a post outside Rouen within a week, a move that would pull him off the case entirely. Convinced that the transfer is a deliberate tactic to derail the investigation, Verjeat doubles down and leverages Lefèvre’s street-smart pragmatism to stay in the game.

With time slipping away, they craft a risky plan. Realizing that momentum and timing could decide the outcome, Verjeat and Lefèvre devise a complicated scheme to buy more time before the transfer. Their alliance evolves from initial friction into a functional if uneasy teamwork, each using their strengths to outwit the bureaucratic hurdles and to keep Portor squarely in their sights. The plan hinges on balancing procedure with instinct, and on turning political pressure into an opportunity to close in on the killer.

The case hangs on connections that bridge crime and politics. As the investigation tightens, Verjeat grows increasingly convinced that Portor is only part of a larger web—one that implicates the political machinery behind the election. The dynamic between the veteran and the skeptic becomes their strongest asset, allowing them to navigate a maze of influence, fear, and loyalty while pursuing Portor. They push forward, aware that every step could be their last chance to prove guilt and to expose the corruption that shadowed the vote.

In the end, the pursuit tests loyalty, nerve, and the limits of law. With the clock ticking toward Verjeat’s imminent transfer, the duo fights to link Portor to the murder and to reveal the political complicity that enabled the violence. Their success would mean justice for the fallen volunteer and the officer, and it would force the system to reckon with its own complicity in the crime. The story remains faithful to its premise: a tense, morally nuanced game of cat-and-mouse in which two opposites learn to work together to outthink an entrenched power structure.

Q1

Why does Verjeat hold Lardatte responsible for the murders?

Verjeat believes Lardatte bears guilt because Portor, the identified killer, is a thug whose brother actively campaigns for Lardatte's law-and-order candidacy. The detective concludes that the politician who hired the thugs is equally responsible for the violence they commit, making Lardatte complicit in both the murder of the volunteer and the killing of the police officer.

Verjeat suspects the transfer is orchestrated by Lardatte and his police contacts because it comes immediately after he publicly humiliated the councilman during the hostage incident. The timing, from a promising investigation to a sudden promotion and reassignment within a week, suggests political interference designed to remove him from the case before he can connect Portor to the political machine.
