The leads grow increasingly muddled as the investigation proceeds, until Phil puts forward a hypothesis: the two murders might be linked.

Mélissa still bears the scars of her confrontation with Clémence. Craving a rush, she unconsciously gives in to taking unnecessary risks—to the point of alarming Gaëlle, though the latter, too absorbed in her mother’s revelations, struggles to even notice.

Our investigators follow in the footsteps of Paul Gauguin, whose time in Martinique resurfaces in the wake of a crime—the murder of a painter who had come to immerse himself in the work of his master.

Alerted by Phil, Gaëlle and Aurélien sense that Mélissa is hiding something from them and decide to tail her before it is too late.

The murder of an internationally renowned pianist rocks the island. Visiting as part of a mentorship program, the virtuoso was concealing a secret affair with one of her young students—twenty-five years her junior.

Meanwhile, Gaëlle notices troubling signs in Mélissa: nausea, sudden cravings, emotional roller coasters… All clues that, this time, may well herald an unexpected promise.

The lifeless body of a funeral home director is discovered in a cemetery. Since taking the reins of the business, the company had experienced a meteoric rise—achieved through methods that were far from universally accepted.

As for Gaëlle, a minor fender-bender with a clergyman turns into love at first sight—and she is determined not to let this chance slip away.

A renowned fashion designer is found murdered in his studio. Against the advice of her colleagues, Mélissa insists on taking part in the investigation. She is pregnant, certainly—but not incapacitated. As the investigation stalls, a discovery breathes new life into the case: the victim had reportedly been warned—in minute detail—of his own death... by a famous psychic on the island. Meanwhile, Gaëlle refuses to let go of Jason. To stay close to him, she throws herself into the life of his church.

Aurélien’s cousin is found critically injured in her banana plantation by her son. Her employee, however, did not survive the attack.

Etcheverry decides to bring Thaïs onto the case to lend a hand to Mélissa and Gaëlle.

Arnaud abruptly leaves Mélissa’s house. Jason, for his part, has refused to speak to Gaëlle since the night they spent together. At that very moment, the lifeless body of a member of a yole team is discovered on a beach.
