Dept. Q


Dept. Q is a British crime thriller television series created by Scott Frank and Chandni Lakhani, based on the book series Department Q by Danish writer Jussi Adler-Olsen. It premiered on Netflix on 29 May 2025. In August 2025, it was renewed for a second season.

Premise

Top-rated detective Carl Morck is returning to police work. He has recently been involved in an ambush shooting, in which he was badly wounded, his colleague and friend James Hardy was paralysed and a young uniformed police officer was killed. Morck receives a muted welcome since his colleagues generally regard him as arrogant and asocial. Morck is also required to attend therapy sessions for the after-effects of the shooting.
The Scottish government has decided to temporarily concentrate on unsolved crimes, believing that successful outcomes will generate good headlines that improve public opinion regarding the police force. Morck's hard-pressed and under-resourced commander, Moira Jacobson, is offered a substantial budget to set up a new unsolved crimes unit. Preferring to use most of the budget for her own department and current cases, she assigns Morck as the sole officer dealing with a large number of cold cases. Morck is given a semi-derelict basement office/bathroom to work in, the former Shower Quarters of the police station, thus the Q in the series title.
Civilian employee Akram Salim, a Syrian former policeman looking for more challenging work, quietly insinuates himself into Morck's basement and is tasked with organising case files. While doing that, he suggests investigating the missing Crown Office solicitor Merritt Lingard. Joined by a recovering Hardy and young constable Rose Dickson, the misfit team begin looking into Lingard's disappearancethe main case investigated during the first season of the series.

Reception

The review aggregator website Rotten Tomatoes reported an 87% approval rating based on 49 critic reviews. The website's critics consensus reads, "In a sea of generic crime dramas, Dept. Q stakes its claim amongst the thrilling, enthralling, and sublime thanks to a winning cast and veteran creative Scott Frank." Metacritic, which uses a weighted average, gave a score of 69 out of 100 based on 22 critics, indicating "generally favorable".
Kristen Baldwin of Entertainment Weekly gave the series an A− and said, "'Broken people healing themselves by providing closure for crime victims' can be an especially effective sub-genre if the writing, directing, and casting align – and in Dept. Q everything gels beautifully." Lucy Mangan reviewed the series for The Guardian, giving it a rating of 4/5 and describing the script as "sharp and lean, and especially good at channelling Morck's spitting sarcasm". Alan Sepinwall of Rolling Stone wrote, "Goode is an exposed nerve, ready to lash out at anyone around him for the slightest offense, which makes him a good match for Manvelov's understated cool as Akram, who is clearly much more dangerous than his reserved and polite demeanor would suggest." Daniel Fienberg of The Hollywood Reporter commented, "Solid mystery, great ensemble, ample ongoing potential."

According to data from Showlabs, Dept. Q ranked seventh on Netflix in the United States during the week of 2–8 June 2025.
