On March 26, 2026, Netflix unveiled the first season of Jo Nesbø’s Detective Hole, a crime drama that adapts the fifth novel in the Harry Hole saga, The Devil’s Star. The series follows Oslo police detective Harry Hole as he hunts a serial killer who leaves a ritualistic signature only he can decode.

Tobias Santelmann leads the cast as Hole, with Joel Kinnaman playing Tom Waaler, the corrupt officer who becomes the detective’s rival. Supporting performances come from Ellen Helinder, Anders Baasmo, Maxime Baune Bochud, and Peter Stormare. Episodes are directed by Øystein Karlsen and Anna Zackrisson, while Nesbø himself serves as writer.

Critics have noted striking parallels between Detective Hole and Amazon Prime’s long‑running Bosch. Both shows center on a detective named Harry, both protagonists are isolated and obsessive, and each series treats its city as a character—Los Angeles in Bosch and Oslo in Detective Hole. The tone of the new series is noticeably darker, echoing the bleakness of True Detective, yet it retains the procedural core that attracted Bosch’s audience.

The first season comprises ten episodes that chart Hole’s investigation of a serial killer and the personal toll the case takes on his family and colleagues—recurring themes in the source novels. The narrative also delves into the city’s rain‑slick streets, a backdrop praised for its atmospheric quality.

Norwegian author Jo Nesbø, whose crime novels have sold more than 50 million copies worldwide and have been translated into over 50 languages, created the Harry Hole character in 2003. The Detective Hole series marks the first television adaptation of the novels produced by Netflix.

Reviews describe the show as “genuinely suspenseful” and highlight the strong performances of Santelmann and Kinnaman. Some critics point out that the first season feels “overstuffed” and could benefit from a leaner focus, but overall the series is lauded for its moody depiction of Oslo and its tight procedural narrative.

Executive producers include Eric Fellner, Katy Rozelle, Niclas Salomonsson, Rene Ezra, Tim Bevan, and Øystein Karlsen. The series’ budget and financial performance remain undisclosed.

While the first season has been well received, no official announcement has confirmed a second season. The Harry Hole canon extends beyond The Devil’s Star, with more than ten books remaining, offering ample material for future adaptations. Should Netflix renew the series, it could follow the model of Bosch and Reacher, adapting one novel per season.

Detective Hole also underscores the growing popularity of Nordic Noir on global streaming platforms. Netflix’s investment in the show reflects its strategy to diversify its original content with high‑quality international crime dramas.

In sum, Jo Nesbø’s Detective Hole has positioned itself as a formidable contender in the crime‑thriller genre, presenting a darker, more atmospheric counterpart to Bosch. With only one season released, the show’s future remains uncertain, yet the extensive Harry Hole canon offers a clear path for potential continuation.
