In La Maison du péril, the France Télévisions adaptation of Peril at End House for the TV series Les Petits Meurtres d'Agatha Christie, Eléonore (last name not given) is the parallel of Magdala Buckley. She is the cousin of Joséphine de Vilmarais. Eléonore is portrayed by Clémentine Poidatz.
Eléonore has a slightly different backstory and role in the plot compared with Maggie Buckley. Here Eléonore is not asked to come down to stay with Joséphine. The two have been staying together in the same house for a long time. When Joséphine's parents died and she inherited the big house, she asked Eléonore to live with her and they treat each other as sisters. In this adaptation Eléonore is a wealthy woman in her own right and she regularly gives money to support Joséphine's fashion design business as well as the photography hobby of Joséphine's brother Abel. What is similar to the original novel is that Eléonore is secretly in love with a famous aviator Guillaume de Saint-Langis. At the time of the events in the episode she is one month pregnant with his baby. However, this secret relationship has very little to do with the events in the episode.
Like Maggie Buckley, Eléonore is killed, and like her, she is wearing a red shawl loaned to her by Joséphine so that people would think that Joséphine is the intended victim. However the motive is different. In this adaptation, there is no plot device of a will favouring Eléonore and the possibility of exploiting an ambiguity in names which Joséphine could exploit to inherit. Here Guillaume doesn't even go missing or suffer a mishap. Eléonore had been spending a lot of her own money to support the activities of Joséphine and Abel but Eléonore feels that it is time to stop and that the two should stand on their own feet. Joséphine fears suddenly becoming poor and without financial support. But she also knows that Eléonore has made a will leaving a large sum of money to her. Getting this money, and not the fortune of the pilot Guillaume, is the motive for murder.
