Overview
- Nocturne premiered Friday, Oct. 30, 2026 with a two-episode launch on Apple TV and will publish new episodes weekly through Dec. 25, 2026.
- The series adapts Lars Kepler’s novels and relocates the story from Sweden to a small town in western Pennsylvania while keeping Nordic-noir tone and visuals.
- Reviews consistently single out Stephen Graham’s chilling turn as incarcerated killer Jurek Walter and Zazie Beetz’s undercover FBI agent Saga as the show’s strongest elements.
- The first two episodes set up the central mystery—an apparently returned missing boy, his still-missing sister, Jonah Lynn’s reopening of the case, Saga’s undercover placement in Riverside Psychiatric Hospital, and Jurek’s manipulation of a hospital worker—without revealing key plot twists.
- Critics note the show’s polished production and steady pacing but say its slow-burn structure and familiar serial-killer conventions make it watchable rather than distinctly original, a point to watch as weekly episodes unfold.
