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 Chief Inspector Carl Morck is returning to police work, four months after he was badly wounded in an ambush shooting. His colleague and friend Detective Inspector James Hardy was also shot and paralysed, and a young uniformed police officer was killed. Morck receives a muted welcome since his colleagues generally hold him in low regard due to his arrogance and asociality. Morck is also required (against his will) 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. She instead diverts most of the budget to her own department and its current cases, then assigns Morck as the sole officer to deal with a large number of cold cases. Morck is directed to set up his department in Room Q, a semi-derelict room full of office junk in the basement—the former Shower Quarters of the police station, thus the "Q".
Civilian employee Akram Salim, an immigrant from Syria who had worked as "something like" a policeman in that country and who is 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.

On 6 February 2024, Stephen Greenhorn and Colette Kane were revealed to be writing with Frank and Lakhani, with Frank directing the first two episodes. In August 2025, the series was renewed for a second season.
On 27 April 2023, it was announced that the series would be set in Edinburgh, Scotland, as opposed to the Copenhagen, Denmark setting of the source material. Filming took place in Edinburgh between February and June 2024. Scenes for the Jennings property were filmed at Burntisland Docks in Fife, although set on the fictional island of Mhòr. The police station scenes featured Argyle House.
In April 2026, it was announced that filming for the second season would run from July to December of that year, with no date given for its 2027 release. Parts of the second series were shot in Aberdeen, as well as Edinburgh.
In June 2026, Aisling Franciosi, Greg Wise, Nicholas Rowe, Tony Curran, Hamish Clark, Alex Ferns, Ross Anderson, Rebecca Root, Isla Johnston, and Amy Brenneman joined the cast of the second series as Kimmie, Derek Powell, Thomas Fulton, Winnie Calderwood, Christopher Herron, Phil Allenbeck, Ricky Daddario, June Lovesay, Agnes, and Helen respectively.
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."
Viewership According to data from Showlabs, Dept. Q ranked seventh on Netflix in the United States during the week of 2–8 June 2025.
