Apple TV thriller Nocturne features Stephen Graham as serial killer

Apple TV's psychological thriller Nocturne adapts Lars Kepler’s crime novels, starring Stephen Graham as a manipulative, imprisoned serial killer.

The plot centers on a retired detective, played by Liev Schreiber, who is pulled into a new investigation after a long-missing boy appears alive.

The series departs from standard whodunit tropes by shifting the narrative focus to the mechanics of the perpetrator's continued influence from behind bars.
