A new six-part BBC series titled "Hercule" will explore the origin story of a younger Hercule Poirot, delving into his backstory and potential sexual fluidity. The adaptation, set to begin filming in Liverpool with Edward Bluemel in the title role, will portray Poirot as he leaves the Belgian police force to establish his detective business in London.

Unlike previous adaptations and Agatha Christie's original novels, the series is expected to hint at Poirot's subtle attractions to both men and women. A source close to the production described the exploration as nuanced and non-explicit, stating that while "Poirot ends up in bed with anyone" is not part of the narrative, there are "hints that he might be a bit fluid sexually, with attractions to men and women."

Bluemel, 33, will be the youngest actor to portray the iconic Belgian sleuth. The series will also feature Poirot's early encounters with characters like Inspector Japp and Captain Hastings. The cast includes James Nesbitt, Tamsin Greig, Henry Ashton, James D'Arcy, Calvin Demba, Phil Dunning, Jack Gleeson, and Mawaan Rizwan.

Christie herself never detailed Poirot's romantic life. In the 1940 book "One, Two, Buckle My Shoe," he expressed fascination with jewel thief Countess Rossakoff. However, his primary focus in the novels remained solving crimes and his personal habits, such as a penchant for herbal tea and precisely matched breakfast eggs.

David Suchet, who famously played Poirot from 1989 to 2013, has stated that the character was "not actually sexual at all," rather than gay, emphasizing his singular focus on his work. In contrast, Kenneth Branagh's film adaptations introduced a tragic backstory involving a lost female love during wartime.

The forthcoming BBC series is described as "an intimate study of Hercule Poirot the man and an epic portrait of Britain between the wars." It will draw upon three of Christie's early stories, with Poirot first appearing in "The Mysterious Affair at Styles" in 1920. James Prichard, Agatha Christie's great-grandson, expressed confidence in Bluemel's casting, calling him an "extremely talented performer."
