In 2020, pathologist Caroline Muirhead's fiancé, Scottish farmer Alexander 'Sandy' McKellar, confessed to her that he and his twin brother Robert had killed cyclist Tony Parsons in a 2017 hit-and-run on the A82 near Bridge of Orchy and buried the body on the Auch Estate.
I keep thinking about the way Caroline Muirhead films herself. Not the big moments—the confession, the police interviews, the courtroom—but the small ones. The way she holds her phone at arm’s length in the car, her face lit by the dashboard glow, talking to the camera like it’s the only thing that won’t judge her.
The way she cries, then checks the recording, then cries some more. It’s unsettling, this performative vulnerability, this need to document even her own unraveling. And yet, I can’t look away.
Should I Marry a Murderer? is a true-crime docuseries that doesn’t just ask whodunit—it asks what does it do to you when the person you love is the one who did it? The answer, as it turns out, is messy, contradictory, and deeply human. It’s also, at times, infuriating.
The series follows Caroline, a pathologist, as she navigates the fallout of her fiancé Sandy McKellar’s confession: that he and his twin brother Robert killed cyclist Tony Parsons in a 2017 hit-and-run and buried the body on their family estate. The crime itself is horrifying, but the real story here is Caroline’s psychological descent—her love addiction, her trauma responses, her desperate, self-destructive need to believe in Sandy even after he admits to murder.
The docuseries leans heavily on footage she shot herself, from mundane moments to raw, unfiltered breakdowns. It’s intimate to the point of discomfort, like watching someone pick at a wound in real time.
And that’s where the trouble starts. Because while Should I Marry a Murderer? is undeniably gripping—three episodes flew by in a single sitting—it’s also deeply divisive. Some viewers see Caroline as a brave whistleblower, a woman failed by the system, a victim of both her fiancé’s crimes and her own toxic attachments.
"Gripping yet contentious true crime docuseries: it hooks viewers with its intimate perspective and sharply divides opinion on its central figure and focus."
The three-part story is compelling and easy to binge, with self-shot footage and unvarnished emotional moments creating a vivid psychological portrait of Caroline Muirhead and her relationship with Sandy McKellar. The heavy emphasis on her perspective, the extensive selfie-style filming, and the stretched three-episode runtime frustrate many, who question her decisions, doubt parts of her account, and wish the murdered cyclist Tony Parsons and his family were given more space.
Netflix’s 2026 docuseries Should I Marry a Murderer? doesn’t need fake on‑set feuds — the real drama is messier than any writers’ room could dream up. latestnetflix.com's read is that From a director who thought the story was “too crazy to be real” to a Red Bull can that’s now basically a true‑crime prop, here’s the juiciest behind‑the-scenes and real-world fallout around the show, its creators, and its very polarizing star, Dr.Caroline Muirhead.
Love it, hate it, or hate‑watch it, Should I Marry a Murderer? has done the impossible: made a discarded energy drink can, a deeply messy relationship and a soft‑spoken Scottish pathologist the most argued‑about trio in true crime this year.
