Jo Nesbø has written and showrun the Netflix series Jo Nesbø’s Detective Hole, adapting nine episodes of his Harry Hole saga while reworking his novels for television
Jo Nesbø has long been a defining voice in modern crime fiction, with more than 60 million copies sold and translations into 51 languages. Now the Norwegian author has moved from page to production, having adapted and overseen every episode of Jo Nesbø’s Detective Hole on Netflix. In stepping into the role of showrunner — a position uncommon in Norway’s television tradition — Nesbø led the creative team that reimagined his most famous character for a global streaming audience. The series draws principally from The Devil’s Star, while threading in backstory from earlier novels to introduce viewers to Harry Hole’s complicated world.
The process of changing a novel into a visual narrative required a different set of muscles. Nesbø wrote all nine scripts and navigated the tension between authorial control and collaborative interpretation. He has previously seen his work adapted by other filmmakers — notably Morten Tyldum’s 2011 film of Headhunters and the 2017 production of The Snowman — but this project placed him at the center of the camera-side decision making. Working with co-directors Øystein Karlsen and Anna Zackrisson, he allowed scenes and characters to be pushed beyond what appears in print, seeking a televisual language that keeps the novels’ essence while embracing dramatic flourishes suited to serialized storytelling.
Assuming the responsibilities of a showrunner meant acquiring habits that differ sharply from solitary novel writing. Nesbø describes the transition as an emotional learning curve: where novels permit a single creative voice to dictate inner monologue and detail, television requires visual shorthand and trust in collaborators. He had tested screenwriting before — contributing episodes to other projects — but scripting every episode of a nine-part series demanded that he pare back literary impulse and let images carry weight. At the same time, Nesbø retained enough flexibility to let directors and actors shape rhythm and tone, acknowledging that adaptations are a new work built from the novel’s DNA rather than a literal transcription.
The adaptation centers on Harry Hole, a dogged, flawed detective who embodies familiar noir archetypes while remaining a distinct voice in Scandinavian crime fiction. For the screen, Nesbø selected a narrative arc where Hole is already established, which is why the series leans on The Devil’s Star as its spine while summarizing elements from earlier books. Oslo becomes a character in its own right: the city’s streets and institutions are presented as a gritty, lived-in stage for the cat-and-mouse between Hole and his adversaries. Nesbø has emphasized that certain cultural details and types of humor don’t fully translate to English, reinforcing the decision to make the series authentic to its Norwegian roots.
Casting presented its own creative choices. Tobias Santelmann portrays Harry Hole, and the production discovered a layered performance in him after initial screenings: what first seemed too genial evolved into a version of Hole that carries both warmth and a darker edge. Opposite him, Joel Kinnaman plays Tom Waaler, a corrupt detective who becomes central to the unfolding mystery. These actors, guided by Nesbø’s scripts and the directing team, helped translate a literary antihero into a screen presence who feels lived-in, volatile, and propelled by a stubborn moral center despite numerous personal failings.
Beyond this adaptation, Nesbø maintains an active role in cinema and television projects. He has collaborated on screenplays and is involved with other film adaptations of his work, including a version of Blood On Snow that he helped draft and a screenplay co-written for a film adaptation of The Night House. These ventures illustrate how contemporary novelists can operate across media, moving between crafting long-form fiction and writing for visual storytelling. Nesbø also draws on a varied past — from professional sports to music — which informs his narrative instincts and his willingness to experiment with tone and form.
At the heart of his creative approach is a pragmatic loyalty to readers’ imagination: Nesbø writes with a compact sense of storytelling borne from early experiences composing lyrics and telling family tales. He says he writes largely for two imagined friends who share his taste in music and film, rather than for trends or industry metrics. While the appetite for book adaptations appears strong across platforms, Nesbø stays focused on crafting characters and plots that can survive the shift from novel to screen — trusting that faithful spirit, not literal fidelity, keeps the work recognisable.
In the end, Jo Nesbø’s Detective Hole represents a full-circle moment: the creator of Harry Hole has translated the detective’s world into a serialized visual form while embracing collaboration and reinvention. For fans of Scandi noir and newcomers alike, the series offers both a faithful emotional core and new dramatic contours, shaped by a writer who chose to move into the director’s seat and shepherd his own creation into the streaming era.
