Better Than Shetland And Darker Than The Loch…! BBC’s Forgotten Island Crime Thriller Is The “Outstanding” Mystery Viewers Are Binge-Watching — And Series 2 Will Bring An Even More Chilling Case
For fans of atmospheric detective dramas filled with secrets, family betrayal and haunting landscapes, the BBC may have just uncovered its next obsession.

While shows like Shetland and The Loch have earned a loyal following for their gripping mysteries and isolated settings, another Scottish crime drama has quietly been winning over viewers with its darker story, emotional characters and unforgettable atmosphere.
The Island has been described as an “outstanding” detective thriller, offering a slow-burning investigation where every character appears to be hiding something — and every secret could change everything.
Set against the breathtaking but isolated backdrop of Scotland’s Western Isles, the drama follows Family Liaison Officer Kat Crichton, a woman forced to return to the island she escaped years earlier after a shocking murder tears through the local community.
But this is no ordinary investigation.
The deeper Kat digs, the more she discovers that the crime is connected to the people she thought she knew — and to a painful past she has spent years trying to leave behind.
A remote island. A brutal murder. A past that refuses to stay buried.
A Murder Mystery Wrapped In Secrets
The story begins when Kat is assigned to investigate the death of a woman found at a remote island mansion belonging to wealthy businessman Sir Douglas Maclean.
At first, the case appears to be a simple burglary that went horribly wrong. However, Kat immediately senses that something does not add up.
Despite Sir Douglas surviving the attack, Kat believes the powerful businessman may know more than he is admitting.
As the investigation continues, the detective becomes drawn deeper into the complicated world of the Maclean family — a wealthy but deeply troubled family where old grudges, hidden relationships and unanswered questions slowly begin to emerge.
The murder forces Kat to confront memories from a decade earlier, including a mysterious New Year’s party where the roots of the tragedy may have first been planted.
The island may look peaceful from the outside, but beneath the surface lies a community filled with secrets.
One of the biggest strengths of The Island is its atmosphere.
Rather than relying only on shocking twists, the series builds tension slowly, creating a feeling that danger is always just around the corner.
The dramatic Scottish scenery adds to the mystery, with the isolated landscapes making the perfect setting for a story about suspicion, guilt and hidden truths.
Fans of Nordic crime dramas will recognize the same slow-burn style that made shows like The Killing and Broadchurch so addictive — a world where character emotions are just as important as solving the crime.
Viewers have praised the series for its gripping storytelling, calling it a “must-watch” for anyone who loves detective mysteries.
Many fans have also highlighted the strong performances, particularly from Sorcha Groundsell, who plays Kat Crichton.
A Complex Detective With Her Own Secrets

Kat is not the typical crime investigator.
While she is determined and intelligent, she is also carrying years of emotional pain from leaving the island behind.
Returning home means facing people and memories she has tried to forget, making the investigation much more personal than she expected.
Groundsell has described Kat as someone who has worked hard to rebuild her life but still has unresolved emotions connected to her past.
That personal conflict gives the series another layer, as viewers watch Kat not only search for a killer but also confront the parts of herself she has been running from.
A New Mystery Is Coming In Series 2


The good news for fans is that the story is far from over.
A second series of The Island is already in production, bringing Kat back for another dark investigation.
The upcoming episodes will introduce a brand-new mystery after the discovery of a young woman’s body beneath a local bridge.
As Kat investigates, she uncovers disturbing secrets surrounding missing young islanders and a possible killer hiding within the community.
The new storyline promises to be even darker, with Kat forced into a dangerous search that could expose some of the island’s most shocking secrets.
Why Crime Drama Fans Should Watch
For viewers who love shows where every character has something to hide, The Island delivers everything needed for a gripping mystery.
It has the isolated setting of Shetland, the dark secrets of The Loch, and the emotional intensity of a classic BBC thriller.
With its haunting atmosphere, complicated characters and slow-burning suspense, the series proves that some of the best crime dramas are the ones hiding quietly in the background.
A beautiful island. A terrifying secret. And a detective story that keeps getting darker with every episode.
