In the twelfth episode of season 36 of Les  Mystères de l’amour  , broadcast on Sunday, April 13, 2025 on TMC, Ingrid ( Carole Dechantre ) is convinced that Natacha is linked to the disappearance of Peter’s ( Serge Gisquière ) hard drive . As a reminder, Nicolas and Ingrid are investigating to help Eve find Peter’s hard drive.

Ingrid confides that Natacha has always been attracted to money. She thinks Nicolas will manage to get her to talk because she’s crazy about him. She admits that she already had a crush on him back when Natacha worked with her. In front of Jimmy, Laly, and Hélène, Ingrid explains that her plan is to use Nicolas ( Patrick Puydebat ) to get Natacha to talk.

Later, Ingrid and Nicolas are in the car. Before going to Natacha’s house, Nicolas doesn’t seem very confident. But Ingrid emphasizes that it’s the only way to recover Peter’s hard drive. Then, she gives him a micro-transmitter so she can hear what’s happening. Ingrid also gives him an earpiece so she can dictate what he needs to say.

Before getting out of the car, André, the other actor in the series alongside Natacha and the prime suspect in the hard drive theft after his date with Eve ( Eve Peyrieux ), also goes to the café. This disrupts Nicolas and Ingrid’s plan. But Ingrid advises him not to give up and to wait. Nicolas then receives a message from Natacha. She says she’s not ready and asks him to wait before going upstairs.

The Mysteries of Love: Nicolas’s infidelity revealed, Ingrid in shock

Ingrid understands that she’s going to try to get rid of André ( Nicolas Audebaud ). They have to wait for André to come out again. Meanwhile, Ingrid desperately wants to kiss Nicolas. He refuses, because he needs to get ready for Natacha. Later, André finally leaves, and Nicolas is able to go to the date. Before leaving, Ingrid reminds him that he has to drive her wild and go as far as he can. Ingrid kisses Nicolas on the lips to give him courage.

So, Nicolas arrives at Natacha’s (Joyce Franrenet ). She apologizes for keeping him waiting and compliments him. But during the conversation, Natacha brings up her past relationship with Nicolas. Ingrid, who overhears the conversation, realizes that Nicolas cheated on her back then. Natacha continues with the compliments and gives details about their relationship.

Nicolas is embarrassed because he knows Ingrid can hear everything. Natasha ends up kissing Nicolas, but Ingrid tells her to stop. He finally puts the plan into action and pretends to be broke. But Natasha doesn’t tell him anything about the hard drive.

The mysteries of love  can be seen every Sunday from 8 p.m. on TMC.
