Marrascaud is one of the twelve criminals who appeared in The Labours of Hercules, a short story collection written by Agatha Christie and features Belgian detective Hercule Poirot, and the main antagonist of its TV series episode adaptation in ITV's Agatha Christie's Poirot. The killer appeared in the fourth story, The Erymanthian Boar. He is soon revealed to be a seemly waiter known as Gustave.
In original story
Poirot takes a funicular to the mountain-top hotel of Rochers Neiges. Poirot introduces himself to Gustave tells Poirot that in fact, he is M. Drouet, a police inspector. They discover that before Gustave,
Poirot announces that Gustave is not Drouet but Marrascaud. It was "Robert" who was Drouet; Marrascaud killed him and took his place. We learn that during his first night in the hotel, Poirot did not drink his coffee, as he suspected it was drugged, and actually witnessed Gustave entering his room, rifling his pockets, and finding the note from Argenteui.
In Agatha Christie's Poirot
Marrascaud appeared in The Labours of Hercules, the third episode in the thirteenth season of Agatha Christie's Poirot, as the main antagonist. Unlike in the novel, the titular Labours are not undertaken by Poirot as cases, but rather refer to a series of paintings that are stolen by Marrascaud, the main villain; the title is also symbolic of Poirot's path to redemption after his plan to snare Marrascaud leads to the senseless murder of an innocent girl, Lucinda LeMesurier. The most significant departure from the source material is the change in Marrascaud's identity; in the novel, it is Gustave who is Marrascaud, but in the adaptation, it is Alice Cunningham, with Gustave being her accomplice (along with Dr. Lutz).
