“The Investigator: A British Crime Story” is a documentary series that has captivated true-crime enthusiasts worldwide. Available on Netflix, this gripping show delves into real-life unsolved cases, uncovering fresh evidence and offering new perspectives on some of Britain‘s most mysterious and chilling crimes.
Created by Mark Williams-Thomas, a former police detective and criminologist, the series provides a thorough investigation of cases that have long haunted the families involved. Through a mix of dramatized scenes, interviews, and reconstructions, Williams-Thomas re-examines each case to uncover secrets that were previously overlooked or ignored.

The Premise of the Show
At the heart of “The Investigator: A British Crime Story” is Mark Williams-Thomas, a criminologist with extensive experience in investigating high-profile crimes. The series is unique in that it blends investigative journalism with dramatic reenactments, allowing viewers to engage not only with the facts of each case but also with a cinematic retelling of events. Each episode focuses on a different cold case, where Williams-Thomas and his team work to bring new evidence to light and, in some instances, push law enforcement to revisit old investigations.
The primary strength of the series lies in its ability to blend documentary and drama. It doesn’t just focus on recounting facts but takes viewers on an emotional journey. The show follows Williams-Thomas as he interviews witnesses, speaks to the families of victims, and uncovers new leads that can potentially crack the cases wide open. It is this process of reinvestigating and, at times, reopening cases that sets “The Investigator” apart from other crime documentaries.
Season One: The Case of Carole Packman
The first season of “The Investigator” focuses on the mysterious disappearance of Carole Packman in 1985. Packman, a mother and housewife, vanished without a trace after visiting a solicitor to file for divorce from her husband, Russell Causley. Despite the lack of physical evidence or a body, Causley was convicted of her murder. However, doubts remained about his guilt, and the case was marked by unresolved questions.
Williams-Thomas revisits the case in order to uncover the truth. He works with Carole’s daughter, Sam, who has spent years searching for answers about her mother’s fate. The investigation reveals shocking new details, including a possible sighting of Carole long after she was presumed dead. The documentary dives into the story of Russell Causley’s deceit and fraud, including an attempt to fake his own death in a life insurance scam. In the course of his investigation, Williams-Thomas unearths evidence that suggests Causley may have been more involved in his wife’s disappearance than originally thought.
One of the major breakthroughs in this investigation came when Williams-Thomas uncovered new evidence that led the Dorset Police to reopen the case. This was a significant moment in the series, as it showed how modern investigative techniques could still impact long-closed cases. For many viewers, it was a powerful reminder that justice can be pursued, even after decades have passed.
Season Two: A Focus on Serial Killers
The second season of “The Investigator” shifts its focus from one mysterious case to multiple chilling stories tied to serial killers. Williams-Thomas investigates the crimes of Peter Tobin and Angus Sinclair, two infamous figures in British criminal history. The season provides a chilling look at how the authorities initially failed to connect the dots between these killers and their victims, leaving families in despair for years.
Peter Tobin and the Disappearances of Louise Kay and Jessie Earl
Peter Tobin is a convicted serial killer who was involved in several high-profile cases. In Season Two, Williams-Thomas revisits the 1988 disappearance of Louise Kay, a young woman who went missing after a night out in Eastbourne. Despite investigations at the time, the case remained unsolved for decades. Williams-Thomas’s investigation uncovers new evidence that links Tobin to Kay’s disappearance. He also connects Tobin to the disappearance of Jessie Earl, another woman whose murder had gone unsolved.
Through interviews with witnesses and extensive research, Williams-Thomas uncovers significant links between Tobin’s whereabouts and the missing women, eventually leading to a deeper understanding of his criminal behavior. This season, like the first, emphasizes the importance of revisiting old cases and asking new questions to uncover the truth.
Angus Sinclair and the Murders of Young Women
In addition to Tobin, Williams-Thomas also investigates the crimes of Angus Sinclair, a convicted serial killer responsible for the murders of two women. Sinclair was also suspected of being involved in the deaths of several other women, but for years, law enforcement was unable to connect him to these crimes. The series brings fresh attention to the case of the murdered women, including Anna Kenny, Hilda McCauley, and Agnes Cooney, whose deaths remained unexplained.
Through new research and interviews with law enforcement and witnesses, Williams-Thomas uncovers crucial evidence that links Sinclair to these murders, pushing authorities to reconsider their earlier conclusions. This investigation highlights the importance of persistence in the pursuit of justice, even when years have passed since the crimes were committed.
The Impact of the Show: Bringing Justice to Cold Cases
One of the most significant aspects of “The Investigator: A British Crime Story” is its potential to bring justice to cold cases. Throughout the series, Williams-Thomas uncovers crucial pieces of evidence that were previously overlooked or dismissed. His investigations have led to the reopening of several cases, such as that of Carole Packman, demonstrating the power of re-examining evidence with fresh eyes. This aspect of the show is not just about entertainment; it serves as a reminder that cold cases are never truly closed and that there is always potential for new breakthroughs.
The series also highlights the emotional toll that unresolved crimes take on the families involved. For viewers, seeing the pain and frustration of the victims’ loved ones brings a human element to the story. It is not just about solving a crime, but about seeking closure for those left behind. The work done by Williams-Thomas offers these families a renewed sense of hope that justice can still be achieved.
The Format and Reception
