Dulcie Lang

Dulcie Lang was a non-canonical character who was created for the film adaptation of Four and Twenty Blackbirds in Season 1 of ITV's Agatha Christie's Poirot. In the film, Dulcie was the model of artist Henry Gascoigne. She possessed several of Henry's oil paintings of her which he had given to her as a gift. As Henry did not allow his oils to be sold while he was alive, the paintings became very valuable after his death. This became a motive for Henry's murder and made Dulcie a suspect. However, Dulcie insisted to Poirot and Hastings that she would not be selling them at any price. Later, Hastings found out that Dulcie had an alibi. She was a model as a still life session during the time of the murder.

Dulcie Lang was played in the film by Holly De Jong. This character does not occur in the original story.
