Who Is Ben Field?
Benjamin Luke Field was a volunteer churchwarden and doctoral student living in Buckinghamshire, England. Before his arrest, he was active within his local church community and was reportedly preparing for a future in religious ministry. Those who encountered him publicly often viewed him as intelligent, articulate, and deeply involved in church life.
Investigators later alleged that behind this public image, Field systematically manipulated vulnerable older individuals for financial gain. His relationship with retired English teacher and novelist Peter Farquhar became the center of one of the UK’s most closely followed criminal investigations. The case stood out because prosecutors argued that psychological coercion and deception played a major role in the victim’s death rather than straightforward physical violence.
The Relationship With Peter Farquhar
Peter Farquhar was a respected retired teacher, author, and devout Christian living in the village of Maids Moreton. He developed a close relationship with Field after meeting through church activities.
During the trial, prosecutors argued that Field convinced Farquhar they were involved in a genuine romantic relationship while secretly pursuing financial benefits. Evidence presented in court suggested that Farquhar rewrote parts of his will and increasingly relied on Field emotionally.
Investigators also alleged that Field isolated Farquhar, manipulated his emotional wellbeing, and encouraged circumstances that ultimately contributed to his death. The prosecution described the relationship as carefully engineered for financial advantage rather than genuine affection.
The Investigation Into Peter Farquhar’s Death
Peter Farquhar died in October 2015. Initially, his death appeared consistent with alcohol-related causes.
However, concerns soon emerged after friends, relatives, and investigators noticed unusual circumstances surrounding the events leading to his death. Police uncovered diary entries, digital evidence, financial records, and witness testimony suggesting that Farquhar had experienced prolonged psychological manipulation.
The investigation expanded further when authorities examined Field’s interactions with another elderly resident, retired headteacher Ann Moore-Martin. Prosecutors alleged that similar patterns of deception had been used in an attempt to benefit financially from her estate as well.
These discoveries transformed what first appeared to be a natural or accidental death into a major criminal investigation.
The 2019 Trial
Murder and Fraud Charges
In 2019, Field stood trial at Oxford Crown Court.
The prosecution argued that he deliberately manipulated Peter Farquhar over an extended period before causing his death through a combination of alcohol and medication. Prosecutors described the conduct as calculated and financially motivated.
Field denied murdering Farquhar but admitted deceiving both Farquhar and Ann Moore-Martin for financial reasons. He pleaded guilty to several fraud and burglary offences connected to the victims.
The jury ultimately convicted him of murdering Peter Farquhar while acquitting him of attempting to murder Ann Moore-Martin, whose death was later determined to have resulted from natural causes.
Sentence
Following the conviction, Field received a life sentence with a minimum term of 36 years for murder. He also received concurrent prison terms for fraud and burglary offences involving both victims.
The judgment attracted widespread media coverage because of the unusual nature of the prosecution’s case, which relied heavily on evidence of psychological manipulation rather than direct eyewitness testimony.
Why the Case Became So Well Known
Several factors made the Ben Field case particularly notable.
First, investigators described a pattern of “gaslighting,” in which victims were allegedly manipulated into questioning their own judgment and reality.
Second, both principal victims were elderly, deeply religious individuals whom prosecutors said had been deliberately targeted because they were emotionally vulnerable.
Third, Peter Farquhar had documented much of his personal life through diaries, providing investigators with unusually detailed insight into his declining emotional and physical condition.
Finally, the legal issues surrounding causation—whether Field legally caused Farquhar’s death despite Farquhar voluntarily consuming alcohol—became central to later appeals and generated significant legal discussion.
The Sixth Commandment and Public Interest
The case reached an even wider audience in 2023 through the BBC drama The Sixth Commandment.
The series dramatized the relationship between Peter Farquhar, Ann Moore-Martin, and Ben Field while emphasizing the emotional manipulation that prosecutors alleged occurred over several years.
Critics praised the production for focusing on the victims rather than sensationalizing the crimes. The series introduced many viewers to the complexities of coercive control, emotional abuse, and financial exploitation of vulnerable adults.
Interest in the real-life case increased substantially following the programme’s release.
Ben Field’s Appeals
Field appealed his conviction multiple times after 2019.
Earlier appeals in 2021 and 2022 were unsuccessful. However, the Criminal Cases Review Commission later referred the case back to the Court of Appeal under exceptional circumstances, allowing judges to reconsider important legal questions surrounding causation and jury directions.
In April 2026, the Court of Appeal ruled that the jury at the original trial had not been properly directed on key legal issues concerning whether Peter Farquhar voluntarily consumed the whisky that contributed to his death. As a result, the court quashed Field’s murder conviction and ordered a retrial. Importantly, the judges did not declare Field innocent; instead, they determined that the original conviction was legally unsafe because of errors in the jury instructions. Field remained in custody while further legal proceedings continued.
Legal Significance of the Appeal
The appeal attracted considerable attention from legal experts because it addressed complex questions about criminal causation.
The Court of Appeal examined whether a person’s voluntary actions can interrupt the legal chain of causation in homicide cases when another person has allegedly manipulated or deceived them.
The ruling was viewed as legally significant beyond Field’s individual case because it clarified important principles concerning jury directions and criminal responsibility. Although the conviction was overturned, prosecutors were permitted to pursue a retrial while broader legal questions could also be considered by higher courts.
