Fanny Derrien works in baggage at a large airport in Paris. She has many difficulties: she has problems with her boyfriend, her car threatens to stall on the way to work, her colleagues never cease to annoy. One evening she was found dead in the trunk of her car, her boyfriend is the prime suspect. Revel and Rousseau learn that her colleagues had harassed her for months, and she had complained several times to Philippe Galand, her supervisor, whom she trusted.

A psychiatrist is murdered shortly after attempting to contact his brother, a schizophrenic confined in a psychiatric clinic. Soon, Revel and Rousseau discover a scam orchestrated by the insurance manager of the clinic. Services not available have been charged to residents by several doctors at the facility. Among them, an ophthalmologist that the victim had met the day before his death.

The daughter of a prominent businessman is the first to discover the body of her father, who was stabbed while playing golf on a Sunday morning. She had a heated argument the night before with her father about her going to a trendy nightclub that seemed to be the hub of drug trafficking. Revel and Melanie's investigation leads them into a sting operation.

A young architecture student is murdered in the hall of the Gare de l'Est. The investigation of Revel and Melanie Rousseau tells them that he had been selected among the ten finalists in a large architectural project for La Défense. The favorite of the contest is now Xavier Michel Corbin, a famous architect who seemed to exert a strange fascination for the young man who was murdered.

A deputy mayor of Paris is killed in his car one evening as he was driving home a young social worker with whom he had spent the evening. Crime of passion or political assassination, Revel and Melanie Rousseau question the real motive of the murderer. They soon discover that it was the social worker who was the target and that the second murder was a smokescreen designed to cover his tracks.

A triple murder within minutes puts investigators on the trail of a police officer with a personality disorder. This discovery has a profound effect on Revel, as the suspect is his half-brother who he has not seen for years, and he discovers that he is suffering the same disease as their mother.
