Should I Marry a Murderer? – Review | Netflix Docuseries

SHOULD I MARRY A MURDERER? on Netflix is a true crime documentary series in three parts. Not only is it well-made and told, but Dr. Caroline Muirhead is also simply fantastic in her honesty and directness. I could not stop watching it. Read our full Should I Marry a Murderer? docuseries review here!

SHOULD I MARRY A MURDERER? is a Netflix true crime documentary series with three episodes. I binge-watched the entire docuseries, which doesn’t happen too often. Mostly because I simply could not stop. If you think the title of this true crime docuseries sounds bad, then just know that it isn’t too accurate.

Sure, a woman involved with (and even engaged to) a man who admits to having killed someone is the central figure. However, I wouldn’t say she wonders whether she should marry him once she hears about his criminal actions. On the other hand, she can’t quite leave him as the police are relying on her to get evidence.

A life-changing Tinder swipe

While Should I Marry a Murderer? does begin with a Tinder match, the crime isn’t related to the dating app. I say this because we’ve already covered a few true crime Netflix productions about dating gone wrong. From The Tinder Swindler to Love Con Revenge.

In this latest Netflix docuseries, we’re going much darker. Here, a woman believes she has met the perfect man for her, but will soon learn of a terrible secret: Her fiancé reveals a hit-and-run situation. Not only did he kill a man, but he was also driving under the influence and got rid of the body afterwards.

The woman is the young forensic pathologist, Dr. Caroline Muirhead, and the man is Sandy McKellar. What makes Should I Marry a Murderer? such a fascinating watch is how she acts along the way. Very importantly, she makes no excuses and explains quite directly (and emotionally) how her life changed in record time.

Caroline Muirhead brings closure to Tony Parsons’ family

While the victim of the hit-and-run is Tony Parsons, there is another victim in the investigation of this crime: Dr. Caroline Muirhead. Not only does she help the police, but she also becomes a makeshift undercover investigator.

Meanwhile, the police do nothing to help or support her. As the investigation spirals – because they act too fast, which also endangers Caroline Muirhead – she finds herself trapped between helping the police, getting more evidence from talking with Alexander “Sandy” McKellar, and trying to keep her own family safe.

It would be easy to say that she should just run in the opposite direction from Sandy, but they are happy together. Mostly because she has just left a long-term relationship in a very bad way, but still, Sandy makes her happy. And also, because the police continue to rely on her for answers.

Ultimately, the police are treating her in disgusting ways. She’s let down and almost seen as one of the suspects (certainly treated like one), while being forced into dangerous situations. Caroline Muirhead is very honest, and when I questioned her actions, she would end up actively answering those very questions.

Key people interviewed for this Netflix docuseries

Along with Dr. Caroline Muirhead, who is a forensic pathologist from Glasgow, Scotland, so she’s as whipsmart as you would expect, we also hear from many other people involved with the case. From Charles Blackbourne, a bartender who was the last person to see Tony Parsons alive, to Stephen and Margaret Muirhead, Caroline’s parents, and James O’Kelly, Caroline’s friend.

Also, in relation to the investigation and criminal proceedings, Lorna Dawson, a forensic soil scientist, plays a key part. Plus, the wonderfully direct Frances McMenamin, who is a consultant legal advisor for the Scottish Criminal Cases Review Commission, has harsh words for how Caroline was treated as a witness.

Being more open-minded is Mike Wade, senior reporter for The Times, while David Green, former head of homicide and major crime for Scotland’s Crown Office and Procurator Fiscal Service, doesn’t have much respect for what Caroline Muirhead went through. Well, except for an acknowledgement at the very end.

Watch Should I Marry a Murderer? on Netflix now

Should I Marry a Murderer? is a documentary series directed by Josh Allott (The Man with 1000 Kids) and features exclusive interviews with Caroline Muirhead, who describes the entire ordeal from start to finish. It’s a fascinating, scary, and sad story of a life that goes completely off the rails due to a new romantic relationship.

In this three-part documentary, we also get never-before-seen footage from Caroline’s personal archives. She recorded a lot (both videos and sound), which would serve as help for the police. Not that they ever gave her much acknowledgement compared to the grief and danger they placed her in.

Dr. Caroline Muirhead has gone through hell to help bring someone she loved to justice. It resulted in a very negative spiral, and making this documentary cannot have been easy. Fortunately, I hope most viewers will acknowledge that she tried to do the right thing – and paid a huge price for this herself!

Should I Marry a Murderer? is out on Netflix from April 29, 2026.
