Madame Gilda Balmont

In Un meurtre en sommeil, the French Télévisions film adaptation of Agatha Christie's Sleeping Murder, for the season 1 of the Les Petits Meurtres d'Agatha Christie TV series, Madame Gilda Balmont is the wife of tennis instructor Mr Balmont and the parallel of Janet Erskine from the original novel is probably. Gilda Balmont is portrayed by Murielle Colvez.

Like Janet, Gilda's husband also had an affair, in this case with Hélène Poliakov some fifteen years before the events in the episode. Her husband wanted to leave her for the new woman but Gilda jealously held on and persuaded him to see sense and stay with her and their children.

Because her husband had an affair with Hélène, she therefore had a motive for wanting Hélène dead. She would also have a motive for killing Séverina Patrominio whom the police suspect knew something and had been blackmailing Hélène's killer. Gilda is therefore subjected to a handwriting analysis test with the other suspects but the handwriting expert Martin Carot exonerated her because her hand did not match that of the person who wrote Séverina's fake suicide note.

The credits only list her as "Mme Balmont" but her husband calls her "Gilda" in the dialogue.
