Apple TV’s key art for Nocturne is mostly concrete. A stained grey wall fills the frame, Liev Schreiber and Zazie Beetz stand in the upper half with their faces turned away to the left, and at the bottom, small enough to miss on a phone screen, Stephen Graham sits cross-legged on the floor in a rust-brown prison shirt, hands folded, the only one of the three looking straight out. The picture tells you where the weight sits before the synopsis does. The man who is already locked up holds the whole composition together.

Nocturne is an Apple TV original crime drama, a serial-killer procedural adapted from two novels by Lars Kepler, the pen name of the Swedish married writers Alexandra Coelho Ahndoril and Alexander Ahndoril. Schreiber plays Jonah Lynn, an ex-soldier turned homicide detective. Beetz plays FBI agent Saga Bauer, whom Apple’s synopsis calls his surrogate daughter. Graham plays Jurek Walter, the killer. Rowan Joffé created the series for television, and John Hlavin runs it as showrunner.

A killer who is already caught

Most serial-killer stories are chases. Nocturne, on the evidence of its premise, starts after the chase is over. Apple TV’s own short description reads: “When the victim of a notorious killer unexpectedly turns up alive, a detective races against time to find the one person still missing, while his protégé goes undercover to get answers from the killer himself.” The killer is not loose. The question is what he knows, and who is still out there.

The official trailer sharpens that. As TV Insider describes it, Jonah goes to see Jurek, who is held in the basement of a psychiatric hospital, because the police and the FBI believe there are more victims and that people are disappearing again, the way they did before. Jurek offers his own version of why the detective is standing in front of him: he is there “because I brought you here.” A prisoner who claims to be running the investigation from a locked room is an old engine of the genre, from The Silence of the Lambs onward. What Nocturne adds is the price of getting him to talk.

The room next door

That price is Saga. The trailer sets up the plan as an undercover placement, and Jonah argues against it in plain terms: “You’re way too close. You know what he’s done. You know what he’s capable of. He has a way of getting to people. He figures out who you are, you don’t come back.” She goes anyway, and takes the room next to Jurek’s. Her own line in the trailer names the threat precisely: “They say he can walk through walls, but you know his real power? Getting in your head.”

Apple’s synopsis ends on a question aimed at the man who signs off on that plan rather than the woman who carries it out: “how far will Jonah go?” Read from the premise alone, the tension of the series does not sit in whether Jurek escapes. It sits in the corridor between two rooms, and in a detective who left the city to protect his family and now has to decide whether protecting one person means exposing another.

From Stockholm to western Pennsylvania

Kepler’s novels are Swedish through and through. In the books, Joona Linna is a detective superintendent in the Swedish police’s National Operations Department, and Saga Bauer works for the Swedish Security Service. Nocturne moves the map. Jonah Lynn, a name that keeps the sound of Joona Linna, is an ex-soldier who, in Apple’s words, is “tired of working the tough streets of Philadelphia” and moves to a small town in western Pennsylvania for a quiet life. Saga Bauer and Jurek Walter keep the names Kepler gave them, now in an American setting.

The change of landscape is the most visible decision of the adaptation. Stockholm’s institutions give way to a Pennsylvania town that Jonah chose because nothing was supposed to happen there, and the premise turns that retreat into the place the threat follows him. The series combines two books in the Joona Linna cycle: The Sandman, the fourth, and Lazarus, the seventh. The production was previously titled Lazarus, and the first episode carries the title “Lazarus, Come Forth.” Kepler’s novels have sold more than 20 million copies in 40 languages, according to Apple, and the authors are among the executive producers. Kepler’s work has reached the screen before, when Lasse Hallström directed The Hypnotist in Sweden.

Who is behind Nocturne

The credits point to procedural experience on both sides of the Atlantic. Joffé, a BAFTA winner, wrote and directed Brighton Rock and created Tin Star, and wrote Ballad of a Small Player. Hlavin, who developed and writes the series, comes from Shooter, The Shield and The Man Who Fell to Earth. Tim Van Patten, whose credits include Masters of the Air, Franklin and Black Mirror, directs the first two episodes and executive produces. Schreiber and Beetz are also executive producers, Beetz through her company Sleepy Poppy. A+E Studios produces with Range Studios.

Around the three leads, the ensemble includes Bill Camp as Chief Dave Ellison, Rory Culkin as Karl Anders, Chrissy Metz as Ida Frost, Gary Carr as Nathan Pollock and Poorna Jagannathan. Graham arrives with an Emmy, a Golden Globe and an Actor Award behind him, and the marketing places him, quite literally, at the centre of the frame.

The season has not premiered yet, so the open question is the one the premise itself sets. If the only way to find Jurek Walter’s last missing victim is to let him into Saga Bauer’s head, Nocturne will have to decide what finding that victim costs the person who went in, and whether Jonah can still call what he did protection.
