Agatha Christie's Hjerson

Explore this unique Swedish mystery series starring Agatha Christie spin-off character, Sven Hjerson.


Launching on Topic in the US December 1st

Now streaming in the UK on All4

Never before has a spin-off character from Agatha Christie’s literary universe been adapted into a television series, until now. Agatha Christie created Ariadne Oliver, a mystery crime writer who Christie herself admitted to sharing certain similarities with. Ariadne, in turn, has her own master detective: Scandinavian sleuth Sven Hjerson, who loves crudités and cold winter swims and solving murder mysteries. This character is brought to life, and taken to modern-day Sweden to explore new crimes and cases. Johan Rheborg stars in the leading role as detective Sven Hjerson, and his sidekick Klara Sandberg is played by Hanna Alström.

The eight-part-show is a thrilling meta whodunnit set in contemporary Sweden, and the Finnish island of Åland. The new TV series Agatha Christie's Hjerson arrived in Sweden, Norway, Denmark and Finland in August 2021, and in Germany in January 2022.

About the characters

The former investigator Sven Hjerson has solved some of the toughest cases in Swedish crime history. Now retired from the limelight, living on the fringes of society, his life mainly consists of daily routines, a vegan diet, vinyl record collecting and an unhealthy appetite for gossip.

Klara Sandberg is a reality TV producer living with her partner Niklas and their daughter Olivia. Her career has stagnated and she is looking for something new – is this really all that life has to offer? When she manages to successfully pitch the idea for a new TV show starring Hjerson, it could just be the solution to all of her problems. There’s just one snag – she’s never actually met Sven Hjerson...

The role of Klara Sandberg is played by Hanna Alström, acclaimed for her roles in numerous films and television series, including Sameblod, Kingsman: The Secret Service, and Ted – In the Name of Love.

In addition to Johan Rheborg and Hanna Alström in the leading roles, the cast also includes a starring lineup of other actors who appear in various roles throughout the series, including David Fukamachi Regnfors, Alida Moberg, Peter Kanerva, Björn Andrésen, Evelyn Mok, Roshi Hoss, Peter Eggers, Livia Millhagen, Niklas Engdahl, Bengt Braskered, Sanna Sundqvist, Jonas Malmsjö, Shiham Surafa and Joel Spira.
