Lars Kepler

Lars Kepler is the pseudonym of critically acclaimed husband and wife team Alexandra Coelho Ahndoril (b. 1966) and Alexander Ahndoril (b. 1967), authors of the No. 1 internationally bestselling Joona Linna series. With nine installments to date, the series has sold 18 million copies in 40 languages. The Ahndorils were both established writers before they adopted the pen name Lars Kepler, and have each published several acclaimed novels.

“I’m a fan for life!”
Tami Hoag, #1 New York Times best-selling author of The Boy

“Kepler treats us readers to a nonstop roller coaster of suspense, taking us deep into the hearts and minds of perfectly realized characters.”
Jeffery Deaver, #1 New York Times best-selling author of The Goodbye Man

“Kepler’s characters, particularly Joona Linna, are always drawn sharp and deep, like scalpel cuts. Kepler’s prose unrolls as smoothly as a loop of razor wire. But it’s Kepler’s storytelling that really draws blood.”
A. J. Finn, #1 New York Times best-selling author of The Woman in the Window

Liev Schreiber, Zazie Beetz & Stephen Graham to star in new Apple TV+ series based on Lars Kepler’s novels

Apple TV+ just announced their greenlight of a riveting new series based on Lars Kepler’s internationally bestselling crime novels, starring and executive produced by Tony Award winner and Emmy and Golden Globe Award nominee Liev Schreiber (The Perfect Couple, Ray Donovan) and Emmy Award nominee Zazie Beetz (Atlanta, Joker, Deadpool 2), and starring SAG Award winner Stephen Graham (Adolescence, Boardwalk Empire, Greyhound). The 10-episode drama is written and executive produced by BAFTA Award winner Rowan Joffe (Tin Star, The Ballad of a Small Player) and John Hlavin (Shooter, The Man Who Fell to Earth), with Emmy, Peabody and DGA Award winner Tim Van Patten (Franklin, Masters of the Air, Black Mirror) set to executive produce and direct the first two episodes.

Filming is set to begin this summer in Pittsburgh, US.

The project tells the story of Jonah Lynn (Schreiber), an ex-soldier turned homicide detective who, tired of working the tough streets of Philadelphia, moves to a small town in Western Pennsylvania for a quiet life. But, as the town and his family come under attack from the diabolically cunning serial killer Jurek Walter (Graham), Jonah must protect all that he holds dear. When the desperate search for Jurek’s last missing victim forces Jonah to send his adopted daughter, FBI Agent Saga Bauer (Beetz), up against Jurek, how far will Jonah go?

Produced for Apple TV+ by A+E Studios in association with Range Studios, the series is executive produced by showrunners Joffe and Hlavin. In addition to starring, Schreiber executive produces, as does Beetz via her Sleepy Poppy production company. Van Patten, Kepler (Alexandra Coelho Ahndoril and Alexander Ahndoril), Niclas Salomonsson, Øystein Karlsen, David Rysdahl, and Dorothy Fortenberry also serve as executive producers, while Julie Herrin serves as co-executive producer.
