The Murder of Roger Ackroyd Adaptation (Agatha Christie’s Poirot 7x01) * * * * *

I watched the adaptation of The Murder of Roger Ackroyd, based on the novel by Agatha Christie, shortly after finishing the book. One thing became clear very quickly: this adaptation is far more dramatic than the source material.

The novel is almost a cosy mystery. Despite the murder, much of the story revolves around village life, conversations, and the relationship between Poirot and Dr Sheppard. The adaptation shifts the focus firmly onto Poirot, which is actually something many Poirot adaptations do. Interestingly, a surprising number of the original novels are not really about Poirot at all. He often enters the story as an outsider and solves the mystery, while the narrative follows other characters.

In the novel, Dr Sheppard narrates the story. Through his eyes, we meet Poirot, who is supposedly retired and spending his time growing vegetable marrows. One of my favourite moments in the book is when Dr Sheppard initially assumes that Poirot is a hairdresser because of his immaculate appearance and mannerisms. The adaptation removes this entirely because everyone already knows who Poirot is from the start. While this makes sense for a television audience, I thought it was a missed opportunity because it was such a funny introduction.

Many of the actions performed by Dr Sheppard in the novel are given to Poirot in the adaptation. Information that is revealed to the doctor in the book is often revealed directly to Poirot on screen. Poirot also conducts investigations that were originally carried out by Dr Sheppard. As a result, the partnership between the two men feels much less important than it does in the novel.

This is especially noticeable because the book repeatedly positions Dr Sheppard as a replacement for Captain Hastings, who is mentioned as living in Argentina. Poirot and the doctor work closely together throughout the investigation. In the adaptation, Hastings is not mentioned and Poirot largely works alone.

Instead, the adaptation brings back the fan favourite Inspector Japp. He replaces Inspector Davis from the novel, which is a change that makes perfect sense in a long running television series. Japp already has an established relationship with Poirot and audiences know who he is. The adaptation also includes conversations about Poirot's retirement and even a visit to his old London apartment. These additions help connect the episode to the wider television series. Since the Poirot novels were not written in a strict chronological order and often feel scattered across Poirot's personal timeline, these continuity additions work well on screen.

One of the most significant changes involves Roger Ackroyd himself. In the novel, we never really learn how Ackroyd made his fortune. In the adaptation, however, he owns a chemical factory, and Poirot is not merely an acquaintance but one of the investors in the business. This creates a much closer connection between the detective and the victim.

The factory also provides some striking visual settings. Several scenes take place among large industrial machines, pipes, and chemical equipment. Even the final confrontation is moved from Ackroyd's house to the factory. While this is a major departure from the book, it works very well as visual storytelling. The machinery creates a much more dramatic backdrop than a drawing room.

The adaptation also presents Ackroyd as a distinctly modern man. His house is modern, his business is modern, and his outlook feels more progressive than the version I imagined while reading. In the novel, I pictured him living in a traditional country house, something much closer to a classic English estate.

The ages of some characters also felt different. While the novel never explicitly states Dr Sheppard's age, I always imagined both him and his sister Caroline as middle-aged. Caroline especially feels like someone who has spent years at the centre of village gossip. I also found myself wondering whether Dr Sheppard had romantic feelings for Flora Ackroyd, based on some of his observations about her. That interpretation disappears entirely in the adaptation, where both the doctor and his sister are portrayed as considerably older.

The adaptation also adds an additional murder that is not present in the novel. Combined with the darker atmosphere, this makes the story feel less like a traditional village mystery and more like a crime drama.

Perhaps the biggest difference overall is emotional. Because Poirot is a friend and business associate of Ackroyd, he is much more personally involved in the case. There are moments where you can see genuine sadness in him. Earlier in the story, when he learns about the blackmail surrounding Mrs Ferrars, he even warns Ackroyd to be careful. That warning adds an extra layer of tragedy to the events that follow.

There are also significant changes to the ending, though I will avoid discussing them because they would spoil both the book and the adaptation.

Overall, I enjoyed the adaptation. It captures the central mystery while reshaping the story into something more dramatic and more focused on Poirot himself. Some of my favourite moments from the novel are missing, particularly the humour surrounding Poirot's introduction, but the adaptation gains a stronger emotional core and some memorable visual scenes in return. It may not be the same story as the book, but it is an interesting interpretation of one of Agatha Christie's most famous mysteries.
