Shetland S04 R5 Exclusive Official

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. shetland s04 r5

Perez is haunted. Not by ghosts—by guilt. His confrontation with Alice (the grieving mother of one of Malone’s victims) is the episode’s brutal heart. She doesn’t scream or cry. She whispers: “You’re not here to find who killed him, Jimmy. You’re here to find who did the world a favour.” Henshall’s performance is a study in containment—his jaw tightens, his eyes drop. He knows she’s right. Tosh pushes for arrest

The reveal, while emotionally devastating, arrives via a piece of exposition that feels slightly rushed—a sudden memory from a minor character that unlocks everything. Given the show’s usual patient unspooling of clues, this moment clunks. It’s the episode’s only misstep, but it’s a noticeable one.

Perez stands alone at the marina, his parka collar turned against the wind. Tosh (Alison O’Donnell) joins him, and their clipped dialogue tells us everything: forensic results are inconclusive, Malone’s past is leaking to the press, and the station is under pressure from Police Scotland to make an arrest—any arrest.
