He was the very last person you would suspect of preying on the vulnerable.
But supposed committed Christian Benjamin Field mercilessly targeted two pensioners in the quaint Buckinghamshire village of Maids Moreton, murdering one and duping both as part of a plot to get them to change their wills.
The horrifying story of how 69-year-old retired English teacher Peter Farquhar and his neighbour Anne-Moore Martin, 83, were entrapped shocked the nation when the full details emerged in 2019.
Mr Farquhar suffered a campaign of gaslighting and physical and mental torture at the hands of 32-year-old church warden Field, who is serving a minimum 36-year prison sentence for his murder.
Now, first-look pictures of a four-part BBC drama documenting Field’s crimes have been released. Timothy Spall, 66, portrays Farquhar, whilst Anne Reid, 88, plays Ms Moore-Martin in The Sixth Commandment.

Field is portrayed by 26-year-old Irish star Éanna Hardwicke, whilst Sheila Hancock, 90, depicts retired secretary Liz Zettl, who was Field’s third intended target before he was caught.
The Sixth Commandment is directed by Saul Dibb and produced by Frances du Pille. A release date has not yet been announced.
Field was a 20-year-old undergraduate student when he first met Mr Farquhar.
On discovering that both he and his neighbour were wealthy, he decided to seduce them to get his hands on their money.
Pretending to be in love first with Mr Farquhar and then Miss Moore-Martin, he was sexually intimate with both, despite dismissing his male partner as a ‘faggot’ and having feelings of ‘indifference’ towards his female victim.
Once he had gained their trust, Field carried out sinister mind games and plied the pair with alcohol and drugs.
Mr Farquhar’s health deteriorated to the point where he was at times rambling, incoherent and suffering from hallucinations.
In the mornings he would often find himself covered in bruises and his prized possessions missing, with no memory of what had happened.

‘I am finding more joy in life now than ever before in my swift 23 years,’ Field wrote as he began his campaign of abuse.
After his arrest, police uncovered a list of potential future victims which included his own parents and grandparents.
He also fantasised in notebooks about a nighttime murder rampage, predicting he could kill up to 50 people in a single spree.
When Mr Farquhar was found dead by his cleaner in October 2015, the first person she called after the emergency services was Field, who everyone believed was his loyal partner.
In March the previous year, the pair had pledged themselves to one another in a London church service.
The day was particularly special for Mr Farquhar, who wrote in his journal: ‘It is one of the happiest moments of my life. Gone are the fears of dying alone.’
Mr Farquhar, who had struggled with his sexuality for years, had taught English at the private Manchester Grammar School before moving to the prestigious Stowe in 1983.
He was head of English there for 21 years, before deciding to retire in 2004 so he could write novels.
Describing his initial encounter with Mr Farquhar, who was a guest lecturer at his university, Field boasted of the pair’s ‘vulgarly commercial’ relationship.
‘He gives me things, and he gets me for a length of time,’ he wrote.
He explained the relationship in even cruder terms to a friend, writing:
‘He and I have struck a deal which is I pay for nothing and will hang out with him until his eventual death win/win… I’m p [pretty] comfortable w/death.’
Field and a university friend moved into Mr Farquhar’s home as lodgers in 2013.
At the time, he was working in the bakery section at Tesco and as a carer at a nearby nursing home.
There he filmed himself tormenting a resident, telling her she didn’t ‘have any friends and you have never married’.
Anne Moore-Martin, 83, was Field’s second victim. She too was seduced by the criminal. She is portrayed in the upcoming drama by Anne Reid, 88

In 2014, the same month as his and Mr Farquhar’s church ceremony, Field began a relationship with another woman, Setara Pracha, an admissions tutor at Buckingham Universtiy, where he had been a student.
He went on to become a deputy church warden at St Mary’s Church in Stowe and boasted to a friend how he was going to become a vicar.
The abuse he subjected Mr Farquhar to included torturing a pet chihuahua he had given him and making him believe he had dementia.
After his will had been changed in Field’s favour, Mr Farquhar was murdered. He was found to have consumed prescriptions sedatives and alcohol, and police believe he may also have been suffocated with a pillow.
Field initially avoided suspicion and pocketed £20,000 from his victim’s will. When Mr Farquhar’s house was sold by his brother, Field got a further £142,000.
He then moved on to his second victim, Ms Moore-Martin, who he had been introduced to by Mr Farquhar.
The retired teacher and devout Catholic quickly fell under his spell, giving him a key to her house and telling friends she loved him.
Above her dressing table she even hung a framed photograph of him bearing the words: ‘I am always with you’.
In 2016, she gave him £4,000 to buy a car. Having no intention of actually purchasing a vehicle with the money, Field hired a car for a day to dupe her.
He then conned the woman out of £27,000 telling her ne needed the money to help his brother, who he claimed was desperately ill.
On mirrors in her home, he would scrawl messages in white marker. One read: ‘Ben makes you whole, Give the whole to him.’
Another stated: ‘All that you give him will be returned tenfold.’
Convinced by his act, Ms Moore-Martin changed her will in Field’s favour at the end of 2016.

In February 2017 she suffered a seizure and ended up in hospital.
It remains unclear what caused the decline, but she did tell friends days earlier that Field had given her ‘some powder’ which helped her sleep.
Field was however cleared of attempting to kill her.
Once his victim was in hospital, Field was unable to get access to her and the pensioner’s niece, Anne-Marie Blake, became suspicious.
As police began an investigation, Ms Blake changed her aunt’s will to write Field out.
In March 2017, Field was arrested for the first time, but two months later, Ms Moore-Martin died for a massive stroke.
Her niece said in evidence to the jury at Field’s trial: ‘She was tortured by it and found it very difficult to get her head around the betrayal.
‘She said to me, “I am such an intelligent woman. How could I let this happen to myself?”

At his trial, former Stowe School secretary, Ms Zettl, then 101, became the oldest witness in a British murder case.
Field’s co-accused, Martyn Smith, who was cleared of involvement in the deaths of both Mr Farquhar and Ms Moore-Martin, had lived as a lodger with Ms Zettl.
In January 2022, Field began a second bid to have his conviction overturned. The Court of Appeal dismissed a previous challenge in 2021.
