Marianne

In Marseille, Gérard Loiret is found dead on the banks of a river. The murder weapon, found at the bottom of the water, is unusual to say the least: a pétanque ball. Always accompanied by Captain Pastor and with her experience, Marianne must demonstrate sagacity to investigate this unusual murder case, the victim of which is a pétanque player who does not hesitate to "stuff" his boules to win lucrative bets. But that's not all: he will also have to coach Pastor, whose sentimental life is more than lively, and provide psychological support to his faithful clerk, Yves, in the depths of depression and who is struggling to cut the cord with his Mom

Marianne investigates the death of Amandine Laroque, who died after falling into the sea from the top of a rocky eminence. Is it a suicide or a murder? She worked in a detox center for addicts. The employees and patients of the establishment are immediately suspected...

Marianne and Zacharie learn to live together on a daily basis, and thwart the suspicion of Commissioner Franco. Soon, Judge Vauban was called to the scene of a fire breaking out near the creeks. On site, she is introduced to Commander Lamarre, head of rescue operations, who seems very close to Captain Pastor. Arnaud Viguier, a firefighter who responded to a campsite surrounded by flames, was found dead on site. But his body was badly beaten... A letter found in the deceased's belongings calls into question the integrity of one of his colleagues.

Pastor and Vauban are dispatched to the scene of a new crime.

On site, the pair of investigators found a lost earring. They also soon uncover troubled actions on the part of the manager. Meanwhile, the situation deteriorates in court, and Marianne has difficulty juggling her very busy job and her new role as foster family for young Zacharie.

Marianne asks Pastor to let his ears wander to try to glean information about Franco, whose attitude arouses her suspicions. Furthermore, they are investigating the death of Jennifer Duval, 24, a professional rugby player, star of the Gazelles de Provence team...

Marianne now knows that Franco hid information from her concerning the death of Zacharie's mother. But she is called to investigate the death of Brigitta Wagner, housekeeper for the Marrand family for 17 years, found dead in the swimming pool of their property the day after a garden party...
