The Sixth Commandment tells the story of how the meeting of an inspirational teacher, Peter Farquhar (Timothy Spall), and a charismatic young student, Ben Field (Éanna Hardwicke), who bonded over their love of books and involvement with the Church of England, set the stage for one of the most complex and confounding criminal cases in recent memory. It also focuses on how suspicions around Ben’s relationship with Peter’s deeply religious neighbour Ann Moore-Martin (Anne Reid), also targeted by Field, unlocked a series of stunning revelations, culminating in a headline-grabbing trial. The Sixth Commandment captures the initial seductions, the extreme gaslighting, the gripping police investigation and Peter’s killer finally being brought to justice four years after his untimely death.
