Attention, TV lovers! The spy thriller of the year is back - and no, it's not Slow Horses. Dept. Q is the five-star series that spent six weeks in the global top 10 shows when it was released on Netflix earlier this year - and now, it's giving Slow Horses a run for its money and returning for a glorious series 2 with a surprise new cast.
You may remember that series 1 introduced us to emotionally-scarred DCI Carl Morck (Matthew Goode), who had recently returned to work after an attack that left one colleague paralysed and another dead. He's now in charge of cold case unit Department Q, which consists of razor-sharp misfits who solve cases from the basement of an Edinburgh police station - and we're about to meet some interesting new recruits.
While we patiently wait for Dept Q. series 2 to arrive on our screens, here’s everything you need to know about the series, including the cast, plot and how to watch it.
What is Dept. Q about?
An adaptation of the novels of the same name by Danish author, Jussi Adler-Olsen, the first series of Dept. Q, which aired in nine parts, revolved around Carl Morck, a former top-rated detective in Edinburgh who, following an attack that left his partner paralysed and another policeman dead, had taken some time out. Now, it's time to return and he's taken off the homicide unit and tasked with setting up Department Q.
What is Department Q, you ask? Well, it's a cold case unit and the team are tasked with solving cases that have previously been closed or forgotten - often deemed unsolvable. They must also work from the basement of the Edinburgh police headquarters. Essentially, it's nothing more than a PR opportunity for the embattled Edinburgh police department and Carl has no real intention of actually solving any crimes. That is, until he learns of the sudden disappearance of lawyer Merritt Lingard (Chloe Pirrie).
We won’t give any spoilers away here, just in case you're yet to watch series 1, but let's just say that Carl and his team find themselves very invested in the case. And do they solve it? You'll have to tune in to find out.

Netflix's Mona Qureshi and Manda Levin said: “We are raring to return to Carl Morck and his band of glorious misfits at Dept. Q.

Is Dept. Q any good?
Yes - it's certainly giving Slow Horses some competition! The show brilliantly blends the mystery of unsolved cases with the fun of watching a group of unlikely colleagues attempt to get to the bottom of them. It’s the work of genius director and writer Scott Frank who, prior to Dept. Q, co-created, directed, and wrote Netflix’s record-setting The Queen's Gambit, so we probably shouldn't have expected anything less.
How can I watch Dept. Q?
Netflix hasn’t yet shared a release date for Dept. Q series 2, but we're expecting it to air at some point in 2027. As soon as we have a confirmed date, we'll share it here. Until then, you can catch up on series 1 on Netflix.
