**What is The Sixth Commandment about?**

According to the BBC’s synopsis, The Sixth Commandment “tells the story of how the meeting of an inspirational teacher, Peter Farquhar, and a charismatic student, Ben Field, set the stage for one of the most complex and confounding criminal cases in recent memory”.

Farquhar, a lecturer in his late 60s, met Field when he was working at Buckingham University in 2011. Field would go on to manipulate Farquhar into believing that he had fallen in love with him, trying to persuade the academic to change his will, making the student the main beneficiary.

Farquhar died in 2015, and when Field was tried for his murder in 2019, the prosecution said that the younger man had been secretly giving him drugs and spiking his drinks, in an apparent bid to make his death appear to be accidental or suicide.

It also emerged that while the pair were living together, Farquhar experienced extended gaslighting, with Field hiding his things and even erasing contacts in his phone.

Field also struck up a relationship with Ann Moore-Martin, a former headmistress in her 80s, and tried to convince her to change her will to include him, too, writing messages “from God” in lipstick on her mirrors in an attempt to persuade her. When she eventually became aware of his manipulation tactics, she cut him out of her life.
