Danish Thriller The Hartung Case Returns to Netflix With Season 2026

Now, creators return with The Holst Case, featuring a different killer and a new investigation system.

Why The Hartung Case Became a Global Sensation

What to Expect in Season 2: The Holst Case

Season 2, titled The Holst Case, brings back detectives Naia Thulin and Europol investigator Mark Hess. This time, they investigate the disappearance of a 41-year-old woman who had been systematically stalked for months. The perpetrator sent her photos, videos, and an audio file containing an innocent-sounding children's counting song.

When she is found murdered, the detectives link the case to the unsolved homicide of a 17-year-old student two years earlier. The new season promises a more traditional investigation approach, with clues and interrogations driving the narrative.

The Creative Mind Behind the Series
