The writers (led by David Kane) pull off a neat trick. For forty minutes, all evidence points to Sally McColl (a standout guest turn by Anneika Rose), the prison nurse who befriended Malone. Her alibi crumbles; her laptop contains searches for untraceable poisons. Tosh pushes for arrest.
What makes this episode exceptional is how it refuses to separate the investigation from the investigators’ inner lives.

But Perez, in a moment of quiet genius, asks: “Why would a nurse, trained to save lives, leave a murder scene looking like a frantic amateur?”
The episode opens not with action, but with the haunting stillness of a Lerwick dawn. Cinematographer Simon Miller continues his masterclass in atmosphere: the grey, pregnant sky hangs over the peat-stained water like a held breath. It’s a visual metaphor for the community itself—clenched, waiting. The writers (led by David Kane) pull off a neat trick
Shetland S04E05 is not a standalone thriller. It’s a pressure valve. It asks us: what is justice when the law fails? And what does it cost the people who try to answer that question?
The final ten minutes flip the board. We learn the poison wasn’t the cause of death—the blunt force trauma to the back of the skull was. The poison was a cover . And the real killer? The person who had access to Malone’s new identity, his medical records, and a motive no one thought to check: his own sister, living under a different name, who he’d abused as a child.
