In the interview, Rowan Joffé explained that the ten‑part series is adapted from the Joona Linna novels by the Swedish writing team Lars Kepler. He said the adaptation narrows the narrative to the psychological impact of the killer Jurek Walter, played by Stephen Graham, rather than a broad community‑wide investigation.
