In Pension Vanilos, the French Télévisions film adaptation of Agatha Christie's Hickory Dickory Dock, for the Les Petits Meurtres d'Agatha Christie TV series, N'Daye Sissoco is a student studying English literature and who lodges at Pension Vanilos, a hostel run by Solange Vanilos. As commissaire Laurence investigated the murder of Louise Lambert at the hostel and began to uncover a link to an international drug smuggling network, N'Daye came under suspicion because she had claimed to have travelled to England when in fact she had gone to Switzerland. However she explained to the commissaire's satisfaction that she had gone to Switzerland in order to give birth and to put the child up for adoption after an unplanned pregnancy. According to her, the father did not want the child and did not want to marry her. She could not afford to take care of the child because of her studies. There is a scene showing N'Daye probably speaking to the father of the child but there is no indication who he is but he is probably not a fellow lodger at the hostel.
N'Daye is of West African descent and there is a fleeting glimpse of her passport which shows that she is from Senegal. There is no exact parallel in the orginal Christie novel for this character as there wasn't this unwanted pregnancy sideplot. In the original novel, the student studying English literature were both French, René Halle and Geneviève Maricaud. The character of N'Daye is played by Sandrine Salyères.
