Written by Sarah Phelps, the four-part crime drama will star Timothy Spall, Anne Reid, Éanna Hardwicke, Annabel Scholey and Sheila Hancock. 

The series will explore the deaths of inspirational teacher Peter Farquhar (Timothy Spall) and his religious neighbour Ann Moore-Martin (Anne Reid) in the village of Maids Moreton, Buckinghamshire.

The trajectory of Farquhar’s life changed when he met younger charismatic student Ben Field (Éanna Hardwicke), which led to one of the most confusing and intricate criminal cases in recent history.

Field also had a suspicious relationship with Moore-Martin, which led to a series of chilling secrets being revealed. 

Both Farquhar and Moore-Martin were gaslighted and exploited by Field, who took advantage of their isolation and loneliness. 

The drama also examines the dramatic police investigation and high-profile trial that followed their deaths.

The rest of the cast includes Ben Bailey Smith, Conor MacNeill, Adrian Rawlins and Amanda Root. 

The Sixth Commandment has been made in cooperation with Farquhar and Moore-Martin’s families and will celebrate their lives as much-loved friends and family members. 

Timothy Spall commented: "When I received Sarah Phelps’ brilliant scripts I knew this was an essential story to tell. I am honoured to be playing the remarkable Peter Farquhar and hope I do him justice, which is the very least he deserves."

Anne Reid added: “I found the story of The Sixth Commandment extremely disturbing and I feel a great sense of responsibility in portraying this good, kind, trusting woman, Ann, who was so cruelly deceived.”
