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, Séverina Patrominio is the parallel of Lily Kimble in the original novel. Séverina is portrayed by Paty Coquelaëre.
Séverina Patrominio worked for Poliakovs, the parallels of the Hallidays, some fifteen years before the events in the episode. Just like in the original, when the mistress of the house, Hélène Poliakov disappeared, Séverina shared her suspicions with another domestic working in the household, Suzanne Lebloc. In particular she told Suzanne that she believed that Hélène had not gone away but that her husband had killed her. Séverina also told Suzanne that the clothes which Hélène supposedly packed and took away were all wrong--they were winter clothes when the season was summer.
The distinctive of Séverina in this adaptation is that she used what she suspected and had been blackmailing Hélène's killer successfully for some fifteen years. Early in the episode, she comes up to the north of France from Lyons to meet up with Suzanne Lebloc and her husband Lucien. She told Lucien beforehand in a letter that she had come to sort out some things. What these things were are not revealed in the episode. But early in the episode, she apparently met with the person she was trying to blackmail and ended up being killed, after falling from height off the ramparts of Fort de Bondues. Although made to look like a suicide, commissaire Larosière suspected murder immediately because the suicide note was so sketchy.
