Dept. Q: Season 1 is a nine-episode Scottish crime thriller about damaged investigators reopening cases that the police have effectively abandoned. Led by Matthew Goode as the abrasive and traumatized DCI Carl Morck, the Netflix series combines a serialized missing-person mystery with an ensemble drama about guilt, institutional neglect, and professional reinvention.
It is not a documentary, nor is it a light episodic detective procedural. Its strongest appeal is the uneasy partnership at the center: three outsiders gradually turn a basement public-relations exercise into a functioning cold-case unit. Viewers looking for atmosphere, flawed investigators, and a mystery that develops across an entire season will find a lot to engage with; viewers wanting a clean case-of-the-week format may find its pacing and Carl’s hostility more difficult.
What is Dept. Q about?
The season begins after a police shooting leaves a young constable dead and Carl’s partner, DCI James Hardy, paralyzed. Carl survives physically, but returns to work psychologically scarred, isolated from his colleagues, and increasingly difficult to manage.
Police leadership gives him a new assignment: take charge of Department Q, a basement unit supposedly created to revisit Edinburgh’s unresolved cases. The department is also useful as a public-relations project for an under-resourced force. It can make the police appear active without demanding that the institution immediately solve the cases it has neglected.
#1 Best Overall
Carl’s first major investigation concerns Merritt Lingard, a prominent prosecutor who disappeared several years earlier. What begins as an old file with little institutional momentum becomes unexpectedly active when Carl, Syrian-born investigator Akram Salim, and Detective Constable Rose Dickson start following its surviving evidence. Ferry records, island inquiries, old notes, disputed testimony, and connections to other deaths gradually transform the case into a present-tense emergency.
That structure gives the show two equally important engines. One is the question of what happened to Merritt Lingard. The other is whether Carl can function inside a team—and whether the people assigned to Department Q can turn professional marginalization into a source of strength.
A spoiler-light look at Season 1’s structure
The first season contains nine episodes, all available on Netflix. The episodes are designed to be watched in order rather than treated as separate mysteries.
- Episode 1: Carl returns after the shooting and is placed in charge of the new department. The missing prosecutor’s case is introduced.
- Episode 2: Carl and his assistant begin digging into the cold case while Carl’s personal problems disrupt the investigation.
- Episode 3: Carl and Akram retrace the ferry journey toward the Isle of Mhòr, while Rose argues that she belongs in Department Q.
- Episode 4: Rose investigates on the island and Akram discovers a note that changes the direction of the case.
- Episode 5: The prosecutor’s disappearance becomes connected to a death, increasing both the stakes and the pressure on Carl.
- Episode 6: Police activity surrounding the Leith Park shooting intersects with Carl’s unresolved trauma.
- Episode 7: Carl makes dangerous allegations as Rose develops a new line of inquiry involving Sam Haig.
- Episode 8: A clue from the kidnappers brings Department Q closer to the central riddle.
- Episode 9: A decades-old recording helps the investigators assemble the remaining clues while the rescue effort reaches its most urgent stage.
This outline avoids revealing the solution to the Merritt Lingard case. The season’s finale is built around the convergence of the investigation, the shooting’s emotional consequences, and a chamber-based rescue situation, so the final episodes are best experienced without a detailed recap beforehand.

Carl Morck
Matthew Goode plays DCI Carl Morck as intelligent, abrasive, emotionally guarded, and often actively unpleasant. Carl is not introduced as a misunderstood genius whose rough edges are immediately excused. His behavior damages relationships, aggravates his superiors, and makes collaboration difficult.
That abrasiveness is also part of the show’s dark humor. Department Q is meant to look like a managed institutional solution, but its leader is a poor public-relations asset: he is suspicious, blunt, angry, and more interested in evidence than appearances. The comedy comes from that mismatch, not from the cases themselves.
The shooting gives Carl’s hostility a psychological context without turning it into a justification. His guilt over Hardy, his changed professional status, and his difficulty returning to ordinary police work all shape the way he investigates. The cold case becomes a way for him to remain useful, but usefulness is not the same as recovery.
Akram Salim
Alexej Manvelov plays Akram Salim, Carl’s initially unexpected investigative partner. Akram provides practical momentum and a counterweight to Carl’s isolation. Their relationship develops through work rather than instant sentimentality: evidence forces them to rely on one another before either man is especially ready to trust the other.

The investigation advances when different skills, experiences, and instincts are allowed to coexist—even when Carl would prefer to operate by himself.
Rose Dickson
Leah Byrne plays Detective Constable Rose Dickson, a determined officer who pushes to join the department. Rose is not simply an assistant added to complete the team. Her persistence, investigative instincts, and willingness to challenge the unit’s assumptions help Department Q become more than a place where unwanted personnel are stored.
James Hardy
Jamie Sives’s DCI James Hardy remains central even when he is not conducting an investigation. His paralysis and the circumstances surrounding the shooting are the emotional wound around which Carl’s story is organized. Hardy’s presence prevents the season from treating Carl’s trauma as a convenient backstory that can be forgotten whenever the mystery becomes exciting.
The central mystery and the show’s themes
The Merritt Lingard investigation is constructed as a cold case that refuses to remain safely in the past. Carl and his colleagues have to contend with missing evidence, institutional resistance, old power structures, and people who have reasons to keep the original story buried.
Rank #3
The case also lets the show examine the gap between public importance and institutional attention. Merritt is a prominent prosecutor, yet the disappearance has become a file rather than a priority. Department Q’s existence exposes that contradiction: the police can claim to care about abandoned cases while treating the unit as a publicity distraction.
Several themes recur throughout the season:
- Institutional neglect: Cases are not abandoned only because clues run out. Bureaucratic priorities, reputational concerns, limited resources, and professional defensiveness also shape which victims receive sustained attention.
- Guilt after police violence: Carl’s post-shooting trauma affects his judgment, relationships, and sense of identity. The show treats the incident as an ongoing consequence rather than a single inciting event.
- Rehabilitation: Department Q offers Carl, Akram, and Rose a chance to prove themselves, but the series is skeptical of easy redemption. A new job does not automatically repair a damaged person.
- Class and power: The Lingard case moves through institutions and social circles where status can protect people from scrutiny. The investigation is partly a struggle over who is believed and who is allowed to define the official version of events.
- Outsider collaboration: The department succeeds because people who do not fit neatly into the established police hierarchy bring different forms of attention to the work.
Atmosphere, tone, and visual identity
Dept. Q draws on Nordic-noir source material but relocates the story to Edinburgh and its surrounding Scottish landscape. The result is not a straightforward Danish-to-Scottish transfer. It is an English-language television adaptation with a new geographic identity, a different cultural setting, and significant changes to the characters and plot structure.
The atmosphere is grimy, damp, and gothic without becoming purely ornamental. Basements, institutional interiors, ferries, remote island locations, and enclosed spaces all reinforce the sense that the characters are working below the level of the official police operation—physically and metaphorically.
Scott Frank writes and directs the series. Netflix credits him with writing or co-writing all nine episodes and directing six. His creative approach emphasizes controlled mood and psychologically damaged protagonists, while the cast and Scottish setting give the show a distinctly British crime-drama texture. Rob Bullock, Scott Frank, and Andy Harries are executive producers; Chandni Lakhani is also credited as a creator in series information.
The humor is dry and often uncomfortable. Carl’s antagonism produces workplace friction, but the show generally avoids presenting the department as a cheerful found family. Trust develops unevenly, and the characters remain wounded even as they become more capable investigators.

Book versus show: what does Dept. Q adapt?
The series is adapted from Jussi Adler-Olsen’s Department Q crime novels, primarily the first story in the series. That book is published in the United States as The Keeper of Lost Causes and in the United Kingdom as Mercy.
The Keeper of Lost Causes by Jussi Adler-Olsen is the most direct next step for viewers who want to explore the source material. The novel is useful as a comparison, but it should not be approached as a scene-by-scene transcript of the Netflix season. The television adaptation changes the setting from Copenhagen to Edinburgh and reworks character details, relationships, and elements of the plot for its Scottish, English-language production.
Readers who continue through the literary series can look for subsequent Department Q books, including The Absent One (also published as Disgrace), A Conspiracy of Faith (also published as Redemption), The Purity of Vengeance (also published as Guilt), The Marco Effect (also published as Buried), The Hanging Girl, Selfies, Victim 2117, and Natrium Chloride. Titles and availability can vary by country and edition, so readers should check their local market.
Is Dept. Q: Season 1 worth watching?
Yes, if you enjoy serialized cold cases, atmospheric police dramas, and protagonists whose emotional damage is part of the story rather than a decorative character trait. The series is especially well suited to viewers who like Nordic-noir adaptations, ensemble workplace tension, remote-location mysteries, and investigations that reveal the failures of the institutions around them.
The main qualification is Carl. His behavior is deliberately abrasive, and the season spends considerable time showing the consequences of his trauma and isolation. Some viewers will find that complexity compelling; others may find his hostility exhausting. The plotting is also dense, and the season’s momentum can feel measured when the story shifts from procedural discovery to character development.
That trade-off is central to the show’s identity. Dept. Q is not primarily asking, “Can a brilliant detective solve an ingenious puzzle?” It is asking whether neglected people and neglected cases can be brought back into view—and what solving one case can and cannot repair.
Season 2 status
Netflix announced a second season on June 25, 2026. The announcement said that Matthew Goode, Alexej Manvelov, Leah Byrne, and Jamie Sives would return, with additional returning and new cast members, and described production as underway.

Recommended viewing approach
- Watch in order. The Merritt Lingard case and Carl’s recovery arc are serialized across all nine episodes.
- Expect a character drama. The shooting, Hardy’s condition, Carl’s therapy, and the team dynamic receive substantial attention.
- Avoid ending explainers until after Episode 9. The final episodes depend on the gradual assembly of clues and the rescue situation.
- Read the novel afterward if you want comparison rather than prediction. The source book and series share a foundation, but the Edinburgh setting and adaptation changes mean the book is not simply the season in prose form.

The Bottom Line
Dept. Q: Season 1 is a moody, nine-episode cold-case drama whose real subject is the formation of an unlikely investigative team. Its Edinburgh setting, bleak humor, and damaged central detective distinguish it from a conventional procedural. The slow-burn character work and Carl Morck’s abrasive personality will not suit everyone, but viewers willing to follow the full season get a mystery shaped as much by institutional failure and personal trauma as by clues.
