Lord Edgware is a rude and ill-tempered man who nobody likes.Adolf Hitlarious: In-universe - Carlotta Adams's Hitler impersonation is considered very amusing by her audience.Adaptation Dye-Job: Jenny Driver is mostly recognisable, in the book, from her distinctive red hair.

The character's appearance is rather unremarkable in the adaptation, and nothing is mentioned about his looks.

Adaptational Ugliness: When visiting the titular character's mansion in the novel, Hastings gives a lengthy monologue about how handsome the butler (Alton) is, describing the latter as an Adonis.

Alton the butler is mincing and effeminate in the novel, but not in the series.

Jane Wilkinson in the novel, on the other hand, was openly self-centered, which is revealed in the end to be Not an Act she really was that selfish, and she committed three murders because she felt she was in her right to do so.

Jane Wilkinson appears to be a sweet and charming woman, but upon being unmasked reveals herself to be a smug Femme Fatale who enjoys manipulating people.

Adaptation Name Change: Genevieve 'Jenny' Driver from the novel becomes Penny Driver in the series, possibly to distinguish her from Geraldine 'Gerry' Marsh.

But all this is revealed to be an act after she is exposed as the killer, and her deliberate gloating of her final speech comes across as meaner-spirited than the childish amorality she exhibited in her final letter to Poirot in the original book. In this adaptation, she is initially portrayed as a sympathetic victim who is forced to silently endure her husband's cruelty, and her asking for Poirot's help comes across more like a desperate plea than a callous demand.

Subverted with Jane Wilkinson, who in the book is described as a blatantly selfish individual who shamelessly brags about wanting to kill her husband so that she can marry another man, and refuses to take the hint when Poirot tries to refuse her commission to 'get rid' of her husband.

In this adaptation he is a friendly Nice Guy who expresses appreciation for Poirot's help, and ultimately gives him a substantial monetary reward in gratitude for saving him from unknowingly marrying a murderess.

The Duke of Merton from the original novel was very cold and supercilious toward Poirot.

Recurring cast: Captain Hastings, Inspector Japp, Miss Lemon
