Two of television’s most iconic detectives are stepping out of their respective worlds and into the same frame. Douglas Henshall (Shetland) and Matthew Goode (Department Q) join forces in a relentless new thriller that promises to leave both of their original series in the shadows.
At the heart of the story lies the most infamous cold case in history — a decades-old mystery wrapped in betrayal, buried truths, and horrors that refuse to stay hidden. As their characters navigate a labyrinth of psychological manipulation, political corruption, and personal demons, the line between justice and obsession blurs to breaking point.
With Shetland’s brooding atmosphere and Dept Q’s suffocating tension fused into one, this is not just a crossover — it’s a seismic event in crime drama. The stakes are higher, the darkness deeper, and the revelations more devastating than anything either detective has faced before.
Once you step into their investigation, there’s no way back.

BREAKING NEWS: Detectives Douglas Henshall (Shetland) and Matthew Goode (Dept Q) Join Forces in a Dark, Twisted Crime Thriller That Will Eclipse Both Series and Haunt Your Mind — Together They Crack the Most Infamous Cold Case in History!
Crime thriller fans, prepare yourselves. In what is shaping up to be the most explosive collaboration in recent television history, Douglas Henshall — famed for his brooding detective role in Shetland — and Matthew Goode, known for his chilling work in Dept Q, are teaming up for a new crime saga destined to redefine the genre.
The untitled project, currently shrouded in secrecy but rumored to be called Darkness Within, promises a gripping narrative where two of the sharpest minds in crime drama collide. Henshall’s deeply intuitive detective and Goode’s enigmatic investigator join forces to unravel the most notorious cold case the country has ever seen — a mystery cloaked in shadows, deception, and decades-old secrets.
What makes this pairing truly unprecedented is the clash and chemistry between their characters. Henshall’s detective, weathered by years on the force and haunted by personal demons, brings a patient, atmospheric approach reminiscent of the haunting landscapes and slow-burning suspense that made Shetland a cult favorite. On the other hand, Goode’s character injects a razor-sharp, relentless psychological edge, reminiscent of the dark, methodical investigations that defined Dept Q.

Themes of trust, betrayal, and moral ambiguity will be explored with unflinching honesty — all while the detectives navigate a labyrinth of lies that threatens to consume them both.
Critics and fans alike are already buzzing with anticipation, speculating that this series could surpass the success and impact of both Shetland and Dept Q, setting a new benchmark for crime storytelling on television.
With production set to begin imminently, viewers can expect a masterclass in tension, atmosphere, and complex storytelling — a haunting journey that will keep audiences glued to their screens and talking long after the final episode.
