Megre postavlja zamku

The killer, who operates under the cover of night, leaves few traces, and the public and the media put pressure on the police to solve the case. Inspector Žil Megre, faced with the lack of concrete evidence, decides to set a trap to lure the killer. The plan involves the use of a police "decoy" - a young woman who walks the streets of the Marais under the watchful eye of the police, hoping to attract the attacker.
