A third television adaption of the novel was made as an episode for the French series "Les Petits Meurtres d'Agatha Christie" ("The Little Murders of Agatha Christie") on 14 September 2012, under the title ""Le couteau sur la nuque"" ("The Knife on the Neck"). The adaptation changed the setting to a theatre in the city of Amiens, France, in the 1950s, made changes in a number of characters – Christie's detectives were replaced by "Commissaire" Larosière (Antoine Duléry) and his clumsy assistant, "Inspecteur" Lampion (Marius Colluci), while the killer is glamorous actress Sarah Morlant (Maruschka Detmers), and the victim is Morlant's inconvenient husband is fellow actor Pierre Fougère (Jean-Marie Winling) – and featured an additional murder subplot involving the theatre's concierge.
