In the summer, days in Oslo, Norway, stretch on for such a long time that it’s not until the late hours of the night that the sun begins to fade. But with all that light comes lots of shadows, and it’s in that darkness that Jo Nesbø’s Detective Hole takes place.

The nine-episode serial killer mystery is now streaming on Netflix, and you can also watch the trailer above. Get a sneak peek into what happens when antihero Detective Harry Hole (Tobias Santelmann) goes head to head with his fellow police officer and adversary Tom Waaler (Joel Kinnaman).

“Harry Hole isn’t just another detective,” Santelmann tells Netflix. “He’s a character [who] readers around the world have lived with for almost 30 years, and I’m grateful for the opportunity to bring him to the screen. I approached this role with deep respect for Jo Nesbø’s work and for the audience that has followed Harry for so long. At the same time, I had to find my Harry — or our Harry — and I hope we’ve created something that feels true to the spirit of the books while also standing on its own.”

As seen in the trailer, Hole is on the hunt for a serial killer lurking in the dark recesses of Oslo’s streets while also attempting to bring corrupt cop Waaler to justice. It’s no wonder that when Hole is asked how long he’s worked as a detective, his answer is a world-weary one: “Far too long.”

For Kinnaman, playing Waaler was “an exciting challenge” that was also rewarding. “Filming in Oslo, the city so deeply woven into Jo Nesbø’s novels, brings an authenticity to the series that’s impossible to replicate,” he tells Netflix. “Collaborating closely with Jo to explore this darker side of Harry’s world has been a rewarding creative experience, and I’m so proud to help bring this story to the screen.”

With over 60 million books sold worldwide — including a staggering 5.6 million in Norway alone (more than the nation’s population!) — Nesbø’s novels have enthralled readers and defined the Nordic noir genre. The arrival of the iconic Norwegian detective onscreen will offer viewers a look into the many sides of evil. They’ll go on a journey with Hole and Waaler as they work within an ethically blurry criminal justice system to get what they want — no matter the cost, they’re looking for some kind of peace.

“Do you ever think about what makes people like us do what we do?” Waaler asks Hole.

The answer? “To silence those goddamn voices.”
