Agatha Christie's Hjerson is a Swedish mystery television series starring Johan Rheborg as the title character, loosely based on Agatha Christie's minor metafictional character Sven Hjerson.
Background In Christie's novels, Hjerson is the protagonist of a popular series of in-universe murder mysteries written by Ariadne Oliver, a self-parody of Christie herself, whilst Hjerson, an eccentric Finnish detective noted for his vegetarianism, functions as a pastiche of Christie's main protagonist, Belgian detective Hercule Poirot.
Premise Struggling Swedish reality TV producer Klara Sandberg (loosely based on Oliver) pitches a true crime series starring the formerly celebrated Hjerson, who has since become a recluse for mysterious reasons. Determined to get him to sign on, Klara inserts herself into Hjerson's routine, only to be present when a murder occurs on a boat they are both travelling on. Following that investigation, the two become an unlikely sleuthing duo as further mysteries follow.
Departing from his literary counterpart, Hjerson is presented as hailing from the Åland islands. He is bisexual, vegan (with a fondness for crudités) and adheres to strict and specific routines including cold winter swims.
