This episode the story begins, as it so often does, with a gruesome East Anglian murder and a sentence of death by hanging. But who will carry out that sentence? Whose shoulders must carry the fullest and harshest weight of the British law? That’s where the Pierrepoints come in. Henry, Thomas, and Albert, executioners all! Their paths were to cross with those of some of the most notorious criminals of the 20th century, and some of those unfortunate enough to suffer the most terrible miscarriages of justice.
