This true-crime tale of a predator poisoning two vulnerable victims is harrowing and intense – but it is impossible to look away
You may think you are beyond being harrowed at this point; that age, experience and daily headlines testifying to the relentlessly awful nature of the world have created a callus on your soul that protects you from such profound disturbance. Especially via such a quotidian, unassuming – essentially friendly – form as television.
Then along comes something like The Sixth Commandment that – over the course of its four immaculate episodes – shaves that callus off scene by scene and reminds you of what television, people and your heart can still do.
The Sixth Commandment aired on BBC One and is now on iPlayer
