Myra Hindley died three years after this documentary was released, but she had already been surplanted as Britain's most notorious female killer by Rosemary West. Even so, she remained the most hated. Herein we hear from the still grieving mothers of her and Brady's victims as well as Peter Topping, the man who led the investigation.
True crime buffs will be familiar with the later developments, including the games Brady played with the police, and Hindley's attempts to portray herself as an accessory after the facts if not entirely innocent, but the one surprising thing here are the crime scene photographs of their last victim and a photograph of the young girl they tortured at 16 Wardle Brook Avenue.
There have been many far worse monsters since, but the fascination for this particular killer couple is likely to continue long after many of their successors have been buried and forgotten.
