Anthony Chapell

In the short story Yellow Iris, Anthony Chapell ("Tony" to his friends) is a friend of Hercule Poirot and the boyfriend of Pauline Weatherby. He recognised Poirot when he arrived at the "Jardin des Cygnes" restaurant and introduced him to the others at his table and invited him to join them.

Very little is given about the background of Chappell or in what context he is acquainted with Poirot. He is described as a young man and usually cheerful. Poirot had gone to the restaurant because he had received an appeal for help from a mysterious woman. For Poirot Chapell is not at all the person he expected to see there because "It seemed impossible to associate the idea of danger or melodrama with any party of which Tony Chapell was a member." Chapell tells Poirot that he had just quarreled with Pauline that day, and also provides background information about the various people at the table.

At the end of the story, he is reconciled with Pauline and they dance together to "their song".

Portrayals
Anthony Chapell is played by Dorian Healy in the film adaptation of Yellow Iris in Series 5 of ITV's Agatha Christie's Poirot. Here he is a journalist. He first meets Poirot in Buenos Aires during the time 2 years before the events in London, seen mostly in flashback. He is pursuing a story about Barton Russell, an oil prospector, as he senses that something big is going on. He attempts to gain an interview Barton or an invitation to the dinner at "Jardin des Cygnes" through Pauline but Pauline angrily rejects him, saying that he is only using her for his journalistic career and is not in love with her at Chapell finally gets an invitation through Lola Valdez.

Poirot witnesses Anthony's quarrel with Pauline and commiserates and gets him to talk. Chapell fills him in on the backgrounds of the various personalities that he is dealing with.

In London two years later, he has another quarrel with Pauline (he is now engaged to her). She accuses him of "being a fink" for writing an article speculating on the imminent collapse of Sovereign Oil, Barton's company.
